Spring Operator 412cd83c3a URL Cleanup
This commit updates URLs to prefer the https protocol. Redirects are not followed to avoid accidentally expanding intentionally shortened URLs (i.e. if using a URL shortener).

# HTTP URLs that Could Not Be Fixed
These URLs were unable to be fixed. Please review them to see if they can be manually resolved.

# Fixed URLs

## Fixed But Review Recommended
These URLs were fixed, but the https status was not OK. However, the https status was the same as the http request or http redirected to an https URL, so they were migrated. Your review is recommended.

Brian Clozel 46016d090b Use LinkedHashmap to preserve insert order
In several places in the spring-webmvc module, URL patterns / objects
relationships are kept in `HashMap`s. When matching with actual URLs,
the algorithm uses a pattern comparator to sort the matching patterns
and select the most specific. But the underlying collection
implementation does not keep the original order which can lead to
inconsistencies.

This commit changes the underlying collection implementation to
`LinkedHashmap`s, in order to keep the insert order if the comparator
does not reorder entries.

Andy Clement b64d752906 Fix SpEL compilation of static method/property/field operations
Before this change the compilation of a method reference or property/field
access was not properly cleaning up the stack if compilation meant
calling a static method or accessing a static field. In these cases there
is no need for a target object on the stack and it should be removed if
present. For a simple expression it is harmless since the end result of
the expression is the thing on the top of the stack, but for nested
expressions if the inner expression suffered this issue, the outer
expression can find itself operating on the wrong element.

The particular issue covered the case of a static field access but this
fix (and associated tests) cover static method, property and field access.

Brian Clozel f53d01b00a Do not rewrite relative links with FixedVersionStrategy
Prior to this change, the resource handling FixedVersionStrategy would
be applied on all links that match the configured pattern. This is
problematic for relative links and can lead to rewritten links such as
"/fixedversion/../css/main.css" which breaks.

This commit prevents that Strategy from being applied to such links.
Of course, one should avoid to use that VersionStrategy with relative
links, but this change aims at not breaking existing links even if it
means not prefixing the version as expected.

When the plus operator is used between strings in a SpEL
expression and that expression is compiled, it is
important to include a cast if computation of any of
the operands isn't obviously leaving strings on the
stack. Likewise if the stack contents are known to
be strings, a cast should not be included.

Rossen Stoyanchev 0086dd830b Enforce cacheLimit in DefaultSubscriptionRegistry
When the cacheLimit is reached and there is an eviction from the
updateCache, the accessCache is now also updated.

This change also ensures that adding a destination to the cache is
protected with synchronization on the updateCache.

Brian Clozel daf94ea576 PathResourceResolver should not resolve root path
When resolving resources, the PathResourceResolver creates a Resource
instance and checks whether this resource `exists()` and `isReadable()`.
While that last call returns false for folders on the file system, both
calls return true for folders located inside JARs.

If a JAR location is configured as a resource location, then
PathResourceResolver can resolve folders in JARs as valid locations and
candidates for paths resolution.

Prior to this change, the PathResourceResolver would resolve "" as a
valid resource path (here, the "/META-INF/resources/webjars" if
configured, for example) and return a "" path for this resource,
effectively turning all "/" URLs into empty ones "".

This commit fixes the resolveUrlPathInternal implementation by not
allowing empty paths as valid resource paths.

Sam Brannen 40fc260d45 Updated required email dependencies in reference manual
Beginning with Java 6, the JavaBeans Activation Framework (JAF) is part
of the JDK. Thus, there is no longer a need to explicitly include a
dependency on `activation.jar` when using Spring's email support in
Spring Framework 4.0 and higher which anyway requires Java 6 or higher.

This commit therefore removes the JAF requirement from the reference
manual.

Sam Brannen 33b9bd72cc Proper support for Root WAC in Spring MVC Test
The modifications to DefaultMockMvcBuilder performed in conjunction
with SPR-12553 introduced a breaking change: the WebApplicationContext
supplied to DefaultMockMvcBuilder's constructor was *always* stored in
the ServletContext as the root WebApplicationContext, overwriting a
root WebApplicationContext that had been set by the user or by the
Spring TestContext Framework (TCF) -- for example, in
AbstractGenericWebContextLoader. Consequently, the changes in SPR-12553
cause tests that use @ContextHierarchy to fail if web components rely
on the correct WebApplicationContext being stored under the
WebApplicationContext#ROOT_WEB_APPLICATION_CONTEXT_ATTRIBUTE key.

This commit reverts the breaking changes introduced in SPR-12553: if
the root WebApplicationContext has already been set in the
ServletContext of the WebApplicationContext supplied to
DefaultMockMvcBuilder, no action is taken.

Furthermore, this commit introduces new code to address the initial
intent of SPR-12553. Specifically, if the root WebApplicationContext
has NOT been set in the ServletContext of the WebApplicationContext
supplied to DefaultMockMvcBuilder, the application context hierarchy
will be traversed in search of the root WebApplicationContext, and the
root WebApplicationContext will then be stored under the
ROOT_WEB_APPLICATION_CONTEXT_ATTRIBUTE key.

Stephane Nicoll daf12a9723 Allow Cache annotations to not specify any cache name
Since Spring 4.1, a CacheResolver may be configured to customize the way
the cache(s) to use for a given cache operation are retrieved. Since a
CacheResolver implementation may not use the cache names information at
all, this attribute has been made optional.

However, a fix was still applied, preventing a Cache operation without a
cache name to be defined properly. We now allow this valid use case.

default `DestinationResolver` was used.

This commit ensures that if a custom `DestinationResolver` has been set,
it is also configured accordingly for replies.

Brian Clozel c99cc53da1 Fix directories I/O in ResourceHttpRequestHandler
Prior to this commit, the `ResourceHttpRequestHandler` would not
properly handle HTTP requests to **directories contained in JARs**.
This would result in HTTP 500 errors, caused by `FileNotFoundException`
or `NullPointerException`.

This can be tracked to webapp ClassLoader implementations in servlet
containers:
* in Jetty9x, fetching a directory within a JAR as a `Resource` and
getting its InputStream work fine, but attempting to `close()` it
results in a NullPointerException as the underlying stream is null.
* In Tomcat6x, one cannot fetch an InputStream for the same `Resource`
as it throws a FileNotFoundException.

This change adds more try/catch clauses and catches more Exception so as
to result in HTTP 200 OK responses instead of server errors. While this
is inconsistent because the same code path would result in HTTP 404 with
existing directories on the file system, there's no other simple way to
make those checks for resources contained in JARs.

Brian Clozel 89694b009a Fix CachingResourceResolver key generation
When used in combination with GzipResourceResolver, the
CachingResourceResolver does not properly cache results, since it only
takes the request path as a input for cache key generation.

Here's an example of that behavior:

1. an HTTP client requests a resource with `Accept-Encoding: gzip`, so
the GzipResourceResolver can resolve a gzipped resource.
2. the configured CachingResourceResolver caches that resource.
3. another HTTP client requests the same resource, but it does not
support gzip encoding; the previously cached gzipped resource is still
returned.

This commit uses the presence/absence of gzip encoding support as an
input in cache keys generation.

Stephane Nicoll 5f6ae13002 Only require an exception CacheResolver if necessary
Previously, a cache infrastructure with only a CacheResolver would have
worked fine until the JSR-107 API is added to the classpath. When this is
the case, the JCache support kicks in and an exception cache resolver is
all of the sudden required.

The CacheResolver _is_ different as the default implementation does look
different attributes so if a custom CacheResolver is set, it is not
possible to "reuse" it as a fallback exception CacheResolver.

Now, an exception CacheResolver is only required if a JSR-107 annotation
with an "exceptionCacheName" attribute is processed (i.e. the exception
CacheResolver is lazily instantiated if necessary).

The use case of having a CachingConfigurerSupport with only a
CacheResolver was still broken though since the JCache support only looks
for a JCacheConfigurer bean (per the generic type set on
AbstractCachingConfiguration). This has been fixed as well.

Brian Clozel 151e96cac4 Fix InputStream caching in ContentCachingReqWrapper
Prior to this commit, the ContentCachingRequestWrapper would immediately
consume the wrapped request's InputStream when asked for the cached
content; that caused several issues:

* the request body was read in memory even if it wasn't yet consumed by
the application, leading to inefficiencies.
* when requesting the InputStream, an empty InputStream was returned
since the original was already read.

This case only happened for form POSTs requests.

This commit makes sure that the wrapper does not alter the request
expected behavior:

* when getting the inputstream, it is wrapped in order to cache its
content
* when getting request parameters, the request body is cached and its
inputstream is consumed, as expected

Sam Brannen b6f22aa514 Fully support XML config in GroovyBeanDefinitionReader
Prior to this commit, the GroovyBeanDefinitionReader claimed (via its
Javadoc) that it fully supported XML configuration files in addition to
its Groovy DSL; however, this was unfortunately inaccurate since XML
validation was disabled by default which led to certain features of XML
configuration not working. For example, it was impossible to define a
<qualifier> in an XML config file without specifying the 'type'
attribute (which has a default value defined in the spring-beans XSD).

This commit fixes this issue by ensuring that bean definitions in XML
resources are loaded with a "standard" XmlBeanDefinitionReader that is
created with default settings (i.e., with XML validation enabled). With
regard to backwards compatibility, bean definitions defined using the
Groovy DSL are still loaded with an XmlBeanDefinitionReader that has
XML validation disabled by default which is necessary for proper
parsing of the Groovy DSL.

Sam Brannen 55eb5b622c Support XML config fully in web integration tests
Prior to this commit, it was impossible to use all features of XML
configuration (e.g., the <qualifier> tag) in web-based integration
tests (loaded using @WebAppConfiguration, @ContextConfiguration, etc.)
if the Groovy library was on the classpath. The reason is that the
GroovyBeanDefinitionReader used internally by
GenericGroovyXmlWebContextLoader disables XML validation for its
internal XmlBeanDefinitionReader, and this prevents some XML
configuration features from working properly. For example, the default
value for the 'type' attribute (defined in the spring-beans XSD) of the
<qualifier> tag gets ignored, resulting in an exception when the
application context is loaded.

This commit addresses this issue by refactoring the implementation of
loadBeanDefinitions() in GenericGroovyXmlWebContextLoader to use an
XmlBeanDefinitionReader or GroovyBeanDefinitionReader depending on the
file extension of the resource location from which bean definitions
should be loaded. This aligns the functionality of
GenericGroovyXmlWebContextLoader with the existing functionality of
GenericGroovyXmlContextLoader.

Prior to this commit, the implementation of equals() in EncodedResource

work as expected.

This commit addresses this issue by including the charset in the
implementation of equals() and introducing corresponding tests in a new
EncodedResourceTests class. Furthermore, this commit makes
EncodedResource immutable and updates all Javadoc to reflect support
for the encoding and charset properties.

- Added assertions for pre-conditions on method arguments for all

 - Introduced additional tests in TestPropertySourceUtilsTests to verify
   the new pre-conditions.

 - Introduced INLINED_PROPERTIES_PROPERTY_SOURCE_NAME constant for the
   name of the MapPropertySource created from inlined properties; the
   name therefore no longer contains the inlined properties, but the
   original values of the inlined properties can now be logged at debug

Sam Brannen 2b135f0d51 Open up TestPropertySourceUtils for public consumption
Spring Framework 4.1 introduced support for @TestPropertySource;
however, the utilities used to parse inlined properties and add test
property sources to the environment are currently private which
prevents reuse by third-party frameworks like Spring Boot.

This commit addresses this issue by making such utilities public.

 - TestPropertySourceUtils is now a public class.

 - Various utility methods in TestPropertySourceUtils have been made
   public.

 - addResourcePropertySourcesToEnvironment() has been renamed to
   addPropertiesFilesToEnvironment().

 - extractEnvironmentProperties() has been renamed to
   convertInlinedPropertiesToMap().

 - All public methods in TestPropertySourceUtils are now fully
   documented.

Sam Brannen e5d41d91d5 Preserve ordering of inlined props in @TestPropertySource
The initial implementation for adding inlined properties configured via
@TestPropertySource to the context's environment did not preserve the
order in which the properties were physically declared. This makes
@TestPropertySource a poor testing facility for mimicking the
production environment's configuration if the property source mechanism
used in production preserves ordering of property names -- which is the
case for YAML-based property sources used in Spring Boot, Spring Yarn,
etc.

This commit addresses this issue by ensuring that the ordering of
inlined properties declared via @TestPropertySource is preserved.
Specifically, the original functionality has been refactored. extracted
from AbstractContextLoader, and moved to TestPropertySourceUtils where
it may later be made public for general purpose use in other frameworks.

Rossen Stoyanchev f398dd03a7 Pass SockJS session attributes to HandshakeHandler
Before this change the WebSocketTransportHandler passed
Collections.emptyMap as attributes to the HandshakeHandler because
it didn't matter what attributes the underlying WebSocketSession has
since it is wrapped by the SockJsSession and that's what exposed for
use everywhere.

This change has the WebSocketTransportHandler passing the attributes
from the SockJsSession instead since it's more accurate for the
underlying WebSocketSession to have access to the same map instance
and it allows the HandshakeHandler to change the attributes even if
it doesn't need to do that today.

Andy Wilkinson 9499e4166c Fix Animal Sniffer
Jasper Reports’ transitive dependency on spring-context (via
castor-xml which is a new dependency in 6.0.3) was being mapped by
Gradle to a dependency on the spring-context project. For reasons that
I do not fully understand this was causing -source and -javadoc jars
to be added to the project's compile classpath which is used by the
Animal Sniffer Ant task. When the task runs these jars do not exist
which causes it to fail. This commit fixes the problem by adding an
exclusion of org.springframework:spring-context to the Jasper Reports
dependencies in spring-context-support and spring-webmvc.

Brian Clozel 0225a7776c Revisit empty body response support in HTTP client
Prior to this commit, HTTP responses without body (response status 204
or 304, Content-Length: 0) were handled properly by RestTemplates. But
some other cases were not properly managed, throwing exceptions for
valid HTTP responses.

This commit better handles HTTP responses, using a response wrapper that
can tell if a response:

* has no message body (HTTP status 1XX, 204, 304 or Content-Length:0)
* has an empty message body

This covers rfc7230 Section 3.3.3.

Brian Clozel d57f7f8783 Sort handler matches in ResourceUrlProvider
Prior to this change, the `ResourceUrlProvider.getForLookupPath` method
would try to match handlers using the keySet order in the
handlerMappings Map. In case of several matches, the handler used for
the return value could vary, since the registration order in the
handlerMappings can't be guaranteed in the configuration.

This commit now collects all matching handlers and sort them using a
`PatternComparator`, in order to try each handler from the most specific
mapping to the least.

Brian Clozel 4550b4a254 Avoid loss of body content in AbstractRequestLoggingFilter
Prior to this commit, the `ContentCachingRequestWrapper` class would
cache the response content only if the reponse would be consumed using
its InputStream. In case of a Form request, Spring MVC consumes the
response using the `getParameter*` Servlet API methods. This causes the
cached content to never be written.

This commit makes the `ContentCachingResponseWrapper` write the request
body to the cache buffer by using the `getParameter*` API, thus avoiding
those issues.

Brian Clozel 77c8aa53ae Allow relative paths within resource location path
Prior to this change, location paths used for resource handling would

`file://home/user/static/../static/`. When checking if the resolved
resource's path starts with the location path, a mismatch would happen
when comparing for example:

* the location `file://home/user/static/../static/`
* and the resource `file://home/user/static/resource.txt`

This commit cleans the location path before comparing it to the resource

Sam Brannen 0c856b3d22 Support @Configuration as meta-annotation in the TCF
Spring Framework 4.0 introduced support for using test-related
annotations as meta-annotations in the Spring TestContext Framework
(TCF) in order to create custom composed annotations within a test
suite; however, the detection of default @Configuration classes in test
classes was not updated to search for @Configuration declared as a
meta-annotation. Specifically, AnnotationConfigContextLoaderUtils
invokes Class.isAnnotated() which only searches for annotations
declared directly on the class in question.

This commit addresses this issue by refactoring the
isDefaultConfigurationClassCandidate() method in
AnnotationConfigContextLoaderUtils so that it uses
AnnotationUtils.findAnnotation() instead of Class.isAnnotated() for
detecting the presence of the @Configuration annotation, either
directly or as a meta-annotation.

Sam Brannen 7d171e6722 Handle exceptions properly in SpringJUnit4ClassRunner
JUnit 4.9 introduced a regression in BlockJUnit4ClassRunner.runChild()
such that exceptions thrown from methodBlock() cause the current test
execution to abort immediately. As a result, the failing test method is
unrooted, and subsequent test methods are never invoked. Furthermore,
RunListeners registered with JUnit are not properly notified.

In conjunction with SPR-11908, SpringJUnit4ClassRunner was updated to
use the aforementioned changes to BlockJUnit4ClassRunner.runChild().
Consequently, SpringJUnit4ClassRunner now suffers from the same
regression.

This commit addresses this issue by ensuring that any exceptions thrown
during the invocation of methodBlock() are properly wrapped in a JUnit
Fail Statement.

Stephane Nicoll adec0265a4 Restore default transaction manager by name lookup

is represented by an empty string (passing the faulty null check).

= How to contribute to the reference
The Spring Framework reference now uses http://asciidoctor.org/[asciidoctor]. This
document describes how to contribute documentation updates.
== Building with Gradle
You can build the documentation using gradle using the `reference` task. For example, from
the project root execute the following command:
./gradlew reference
the output will be available at `spring-framework/build/reference/htmlsingle/index.html`
== Live editing
One of the nice features about using asciidoctor is the support for live editing.
You will find a Guardfile already present at `spring-framework/src/asciidoc/Guardfile`.
Make sure first to follow the setup instructions within the
http://asciidoctor.org/docs/editing-asciidoc-with-live-preview/[Editing AsciiDoc with Live Preview]
document. Once you have done that, there are additional gems to install to make it work
(assuming that you are using http://livereload.com/[LiveReload]):
gem install guard-rspec guard-livereload
When running `guard start` within the `src/asciidoc/` folder, any changes to the
`src/asciidoc/index.adoc` file will automatically be written at
`src/asciidoc/build/index.html`.
== Troubleshooting
* If you are using LiveReload, make sure to select _Allow access to file URLs_ in the
LiveEdit plugin options of your browser.
* The icon used to enable _LiveReload_ can be a bit confusing. The dot is empty when it is
disabled and full when the plugin is active. Make sure to enable it on the tab
displaying the `index.html` file.
* Ensure you are _not_ running guard start at all as two instances could not run at the
same time. To exit a current session in a clean way, just type e in the shell.
== Documentation notes
Some notes on documentation
* Documentation is wrapped at 90 chars, ensure that you manually wrap your edits
* Tabs are used for indentation, do not use spaces
* Follow the existing style when inserting `source` blocks
* http://asciidoctor.org/docs/asciidoc-syntax-quick-reference/[Asciidoctor Quick Reference]
* http://asciidoctor.org/docs/user-manual/[Asciidoctor Manual]

# Contributing to the Spring Framework
_Have something you'd like to contribute to the framework? We welcome pull
requests but ask that you carefully read this document first to understand how
best to submit them; what kind of changes are likely to be accepted; and what
to expect from the Spring team when evaluating your submission._
First off, thank you for taking the time to contribute! :+1: :tada:
_Please refer back to this document as a checklist before issuing any pull
request; this will save time for everyone!_

### Understand the basics
### Code of Conduct
This project is governed by the [Spring Code of Conduct](CODE_OF_CONDUCT.adoc).
By participating you are expected to uphold this code.
Please report unacceptable behavior to spring-code-of-conduct@spring.io.
### How to Contribute
#### Ask questions
If you have a question, check Stack Overflow using
[this list of tags](https://stackoverflow.com/questions/tagged/spring+or+spring-mvc+or+spring-aop+or+spring-jdbc+or+spring-transactions+or+spring-annotations+or+spring-jms+or+spring-el+or+spring-test+or+spring+or+spring-remoting+or+spring-orm+or+spring-jmx+or+spring-cache+or+spring-webflux?tab=Newest). Find an existing discussion, or start a new one if necessary.
If you believe there is an issue, search through
[existing issues](https://github.com/spring-projects/spring-framework/issues) trying a
few different ways to find discussions, past or current, that are related to the issue.
Reading those discussions helps you to learn about the issue, and helps us to make a
decision.
Not sure what a pull request is, or how to submit one? Take a look at GitHub's
excellent [help documentation][] first.
#### Create an Issue
### Search JIRA first; create an issue if necessary
Reporting an issue or making a feature request is a great way to contribute. Your feedback
and the conversations that result from it provide a continuous flow of ideas. However,
before creating a ticket, please take the time to [ask and research](#ask-questions) first.
Is there already an issue that addresses your concern? Do a bit of searching
in our [JIRA issue tracker][] to see if you can find something similar. If you
do not find something similar, please create a new JIRA issue before submitting
a pull request unless the change is truly trivial -- for example: typo fixes,
removing compiler warnings, etc.
If you create an issue after a discussion on Stack Overflow, please provide a description
in the issue instead of simply referring to Stack Overflow. The issue tracker is an
important place of record for design discussions and should be self-sufficient.
### Sign the Contributor License Agreement
Once you're ready, create an issue on [GitHub](https://github.com/spring-projects/spring-framework/issues).
If you have not previously done so, please fill out and submit the
[SpringSource CLA form][]. You'll receive a token when this process is complete.
Keep track of this; you may be asked for it later!
Many issues are caused by subtle behavior, typos, and unintended configuration.
Creating a [Minimal Reproducible Example](https://stackoverflow.com/help/minimal-reproducible-example)
(starting with https://start.spring.io for example) of the problem helps the team
quickly triage your issue and get to the core of the problem.
Note that emailing/postal mailing a signed copy is _not_ necessary. Submission
of the web form is all that is required.
#### Issue Lifecycle
Once you've completed the web form, simply add the following in a comment on
your pull request:
When an issue is first created, it is flagged `waiting-for-triage` waiting for a team
member to triage it. Once the issue has been reviewed, the team may ask for further
information if needed, and based on the findings, the issue is either assigned a target
milestone or is closed with a specific status.
I have signed and agree to the terms of the SpringSource Individual
Contributor License Agreement.
When a fix is ready, the issue is closed and may still be re-opened until the fix is
released. After that the issue will typically no longer be reopened. In rare cases if the
issue was not at all fixed, the issue may be re-opened. In most cases however any
follow-up reports will need to be created as new issues with a fresh description.
You do not need to include your token/id. Please add the above statement to all
future pull requests as well, simply so that the Spring Framework team knows
immediately that this process is complete.
#### Submit a Pull Request
## Create a Branch
1. If you have not previously done so, please sign the
[Contributor License Agreement](https://cla.spring.io/sign/spring). You will be reminded
automatically when you submit the PR.
### Branch from `master`
1. Should you create an issue first? No, just create the pull request and use the
description to provide context and motivation, as you would for an issue. If you want
to start a discussion first or have already created an issue, once a pull request is
created, we will close the issue as superseded by the pull request, and the discussion
about the issue will continue under the pull request.
Master currently represents work toward Spring Framework 4.0. Please submit
all pull requests there, even bug fixes and minor improvements. Backports to
`3.2.x` will be considered on a case-by-case basis.
1. Always check out the `main` branch and submit pull requests against it
(for target version see [settings.gradle](settings.gradle)).
Backports to prior versions will be considered on a case-by-case basis and reflected as
the fix version in the issue tracker.
1. Choose the granularity of your commits consciously and squash commits that represent
multiple edits or corrections of the same logical change. See
[Rewriting History section of Pro Git](https://git-scm.com/book/en/Git-Tools-Rewriting-History)
for an overview of streamlining the commit history.
### Use short branch names
1. Format commit messages using 55 characters for the subject line, 72 characters per line
for the description, followed by the issue fixed, e.g. `Closes gh-22276`. See the
[Commit Guidelines section of Pro Git](https://git-scm.com/book/en/Distributed-Git-Contributing-to-a-Project#Commit-Guidelines)
for best practices around commit messages, and use `git log` to see some examples.
Branches used when submitting pull requests should preferably be named
according to JIRA issues, e.g. 'SPR-1234'. Otherwise, use succinct, lower-case,
dash (-) delimited names, such as 'fix-warnings', 'fix-typo', etc. In
[fork-and-edit][] cases, the GitHub default 'patch-1' is fine as well. This is
important, because branch names show up in the merge commits that result from
accepting pull requests and should be as expressive and concise as possible.
1. If there is a prior issue, reference the GitHub issue number in the description of the
pull request.
## Use Spring Framework Code Style
If accepted, your contribution may be heavily modified as needed prior to merging.
You will likely retain author attribution for your Git commits granted that the bulk of
your changes remain intact. You may also be asked to rework the submission.
The complete [Spring Framework Code Style][] reference is available on the wiki, but
here's a quick summary:
If asked to make corrections, simply push the changes against the same branch, and your
pull request will be updated. In other words, you do not need to create a new pull request
when asked to make changes.
### Mind the whitespace
#### Participate in Reviews
Please carefully follow the whitespace and formatting conventions already
present in the framework.
Helping to review pull requests is another great way to contribute. Your feedback
can help to shape the implementation of new features. When reviewing pull requests,
however, please refrain from approving or rejecting a PR unless you are a core
committer for the Spring Framework.
1. Tabs, not spaces
1. Unix (LF), not DOS (CRLF) line endings
1. Eliminate all trailing whitespace
1. Wrap Javadoc at 90 characters
1. Aim to wrap code at 90 characters, but favor readability over wrapping
1. Preserve existing formatting; i.e. do not reformat code for its own sake
1. Search the codebase using `git grep` and other tools to discover common
naming conventions, etc.
1. Latin-1 (ISO-8859-1) encoding for Java sources; use `native2ascii` to convert
if necessary
### Build from Source
See the [Build from Source](https://github.com/spring-projects/spring-framework/wiki/Build-from-Source)
wiki page for instructions on how to check out, build, and import the Spring Framework
source code into your IDE.
### Add Apache license header to all new classes
### Source Code Style
```java
/*
* Copyright 2002-2014 the original author or authors.
*
* Licensed under the Apache License, Version 2.0 (the "License");
* you may not use this file except in compliance with the License.
* You may obtain a copy of the License at
*
* http://www.apache.org/licenses/LICENSE-2.0
*
* Unless required by applicable law or agreed to in writing, software
* distributed under the License is distributed on an "AS IS" BASIS,
* WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied.
* See the License for the specific language governing permissions and
* limitations under the License.
*/
The wiki pages
[Code Style](https://github.com/spring-projects/spring-framework/wiki/Code-Style) and
[IntelliJ IDEA Editor Settings](https://github.com/spring-projects/spring-framework/wiki/IntelliJ-IDEA-Editor-Settings)
define the source file coding standards we use along with some IDEA editor settings we customize.
package ...;
```
### Reference Docs
### Update Apache license header in modified files as necessary
The reference documentation is authored in [Asciidoctor](https://asciidoctor.org/) format
using [Antora](https://docs.antora.org/antora/latest/). The source files for the documentation
reside in the [framework-docs/modules/ROOT](framework-docs/modules/ROOT) directory. For
trivial changes, you may be able to browse, edit source files, and submit directly from GitHub.
Always check the date range in the license header. For example, if you've
modified a file in 2014 whose header still reads:
When making changes locally, execute `./gradlew antora` and then browse the results under
`framework-docs/build/site/index.html`.
```java
* Copyright 2002-2011 the original author or authors.
```
Asciidoctor also supports live editing. For more details see
[AsciiDoc Tooling](https://docs.asciidoctor.org/asciidoctor/latest/tooling/).
Then be sure to update it to 2014 accordingly:
```java
* Copyright 2002-2014 the original author or authors.
```
### Use @since tags for newly-added public API types and methods
For example:
```java
/**
* ...
*
* @author First Last
* @since 4.0
* @see ...
*/
```
## Prepare Your Commit
### Submit JUnit test cases for all behavior changes
Search the codebase to find related tests and add additional `@Test` methods
as appropriate. It is also acceptable to submit test cases on a per JIRA issue
basis, for example:
```java
package org.springframework.beans.factory.support;
/**
* Unit tests for SPR-8954, in which a custom {@link InstantiationAwareBeanPostProcessor}
* forces the predicted type of a FactoryBean, effectively preventing retrieval of the
* bean from calls to #getBeansOfType(FactoryBean.class). The implementation of
* {@link AbstractBeanFactory#isFactoryBean(String, RootBeanDefinition)} now ensures
* that not only the predicted bean type is considered, but also the original bean
* definition's beanClass.
*
* @author Chris Beams
*/
public class Spr8954Tests {
@Test
public void cornerSpr8954() {
// ...
}
}
```
### Squash commits
Use `git rebase --interactive --autosquash`, `git add --patch`, and other tools
to "squash" multiple commits into a single atomic commit. In addition to the man
pages for git, there are many resources online to help you understand how these
tools work. The [Rewriting History section of Pro Git][] provides a good overview.
### Use real name in git commits
Please configure git to use your real first and last name for any commits you
intend to submit as pull requests. For example, this is not acceptable:
Author: Nickname <user@mail.com>
Rather, please include your first and last name, properly capitalized, as
submitted against the SpringSource contributor license agreement:
Author: First Last <user@mail.com>
This helps ensure traceability against the CLA and also goes a long way to
ensuring useful output from tools like `git shortlog` and others.
You can configure this via the account admin area in GitHub (useful for
fork-and-edit cases); _globally_ on your machine with
git config --global user.name "First Last"
git config --global user.email user@mail.com
or _locally_ for the `spring-framework` repository only by omitting the
'--global' flag:
cd spring-framework
git config user.name "First Last"
git config user.email user@mail.com
### Format commit messages
Please read and follow the [Commit Guidelines section of Pro Git][].
Most importantly, please format your commit messages in the following way
(adapted from the commit template in the link above):
Short (50 chars or less) summary of changes
More detailed explanatory text, if necessary. Wrap it to about 72
characters or so. In some contexts, the first line is treated as the
subject of an email and the rest of the text as the body. The blank
line separating the summary from the body is critical (unless you omit
the body entirely); tools like rebase can get confused if you run the
two together.
Further paragraphs come after blank lines.
- Bullet points are okay, too
- Typically a hyphen or asterisk is used for the bullet, preceded by a
single space, with blank lines in between, but conventions vary here
Issue: SPR-1234, SPR-1235
1. Use imperative statements in the subject line, e.g. "Fix broken Javadoc link"
1. Begin the subject line with a capitalized verb, e.g. "Add, Prune, Fix,
Introduce, Avoid, etc."
1. Do not end the subject line with a period
1. Restrict the subject line to 50 characters or less if possible
1. Wrap lines in the body at 72 characters or less
1. Mention associated JIRA issue(s) at the end of the commit comment, prefixed
with "Issue: " as above
1. In the body of the commit message, explain how things worked before this
commit, what has changed, and how things work now
For examples of this style, issue a `git log --author=cbeams` in the
`spring-framework` git repository. For convenience, here are several such commits:
- https://github.com/spring-projects/spring-framework/commit/08e2669b84ec0faa2f7904441fe39ac70b65b078
- https://github.com/spring-projects/spring-framework/commit/1d9d3e6ff79ce9f0eca03b02cd1df705925575da
- https://github.com/spring-projects/spring-framework/commit/8e0b1c3a5f957af3049cfa0438317177e16d6de6
- https://github.com/spring-projects/spring-framework/commit/b787a68f2050df179f7036b209aa741230a02477
## Run the Final Checklist
### Run all tests prior to submission
See the [building from source][] section of the `README` for instructions. Make
sure that all tests pass prior to submitting your pull request.
### Submit your pull request
Subject line:
Follow the same conventions for pull request subject lines as mentioned above
for commit message subject lines.
In the body:
1. Explain your use case. What led you to submit this change? Why were existing
mechanisms in the framework insufficient? Make a case that this is a
general-purpose problem and that yours is a general-purpose solution, etc.
1. Add any additional information and ask questions; start a conversation or
continue one from JIRA
1. Mention the JIRA issue ID
1. Also mention that you have submitted the CLA as described above
Note that for pull requests containing a single commit, GitHub will default the
subject line and body of the pull request to match the subject line and body of
the commit message. This is fine, but please also include the items above in the
body of the request.
### Mention your pull request on the associated JIRA issue
Add a comment to the associated JIRA issue(s) linking to your new pull request.
### Expect discussion and rework
The Spring team takes a very conservative approach to accepting contributions to
the framework. This is to keep code quality and stability as high as possible,
and to keep complexity at a minimum. Your changes, if accepted, may be heavily
modified prior to merging. You will retain "Author:" attribution for your Git
commits granted that the bulk of your changes remain intact. You may be asked to
rework the submission for style (as explained above) and/or substance. Again, we
strongly recommend discussing any serious submissions with the Spring Framework
team _prior_ to engaging in serious development work.
Note that you can always force push (`git push -f`) reworked / rebased commits
against the branch used to submit your pull request. In other words, you do not
need to issue a new pull request when asked to make changes.

## Spring Framework
The Spring Framework provides a comprehensive programming and configuration
model for modern Java-based enterprise applications - on any kind of deployment
platform. A key element of Spring is infrastructural support at the application
level: Spring focuses on the "plumbing" of enterprise applications so that teams
can focus on application-level business logic, without unnecessary ties to
specific deployment environments.
This is the home of the Spring Framework: the foundation for all [Spring projects](https://spring.io/projects). Collectively the Spring Framework and the family of Spring projects are often referred to simply as "Spring".
The framework also serves as the foundation for [Spring Integration][], [Spring
Batch][] and the rest of the Spring [family of projects][]. Browse the repositories
under the [Spring organization][] on GitHub for a full list.
Spring provides everything required beyond the Java programming language for creating enterprise applications for a wide range of scenarios and architectures. Please read the [Overview](https://docs.spring.io/spring-framework/reference/overview.html) section of the reference documentation for a more complete introduction.
## Code of Conduct
This project is governed by the [Spring Code of Conduct](CODE_OF_CONDUCT.adoc). By participating, you are expected to uphold this code of conduct. Please report unacceptable behavior to spring-code-of-conduct@spring.io.
## Access to Binaries
For access to artifacts or a distribution zip, see the [Spring Framework Artifacts](https://github.com/spring-projects/spring-framework/wiki/Spring-Framework-Artifacts) wiki page.
## Downloading Artifacts
See [downloading Spring artifacts][] for Maven repository information. Unable to
use Maven or other transitive dependency management tools? See [building a
distribution with dependencies][].
## Documentation
See the current [Javadoc][] and [reference docs][].
The Spring Framework maintains reference documentation ([published](https://docs.spring.io/spring-framework/reference/) and [source](framework-docs/modules/ROOT)), GitHub [wiki pages](https://github.com/spring-projects/spring-framework/wiki), and an
[API reference](https://docs.spring.io/spring-framework/docs/current/javadoc-api/). There are also [guides and tutorials](https://spring.io/guides) across Spring projects.
## Getting Support
Check out the [Spring forums][] and the [spring][spring tag] and
[spring-mvc][spring-mvc tag] tags on [Stack Overflow][]. [Commercial support][]
is available too.
## Micro-Benchmarks
## Issue Tracking
Report issues via the [Spring Framework JIRA]. Understand our issue management
process by reading about [the lifecycle of an issue][]. Think you've found a
bug? Please consider submitting a reproduction project via the
[spring-framework-issues][] GitHub repository. The [readme][] there provides
simple step-by-step instructions.
See the [Micro-Benchmarks](https://github.com/spring-projects/spring-framework/wiki/Micro-Benchmarks) wiki page.
## Building from Source
The Spring Framework uses a [Gradle][]-based build system. In the instructions
below, [`./gradlew`][] is invoked from the root of the source tree and serves as
a cross-platform, self-contained bootstrap mechanism for the build.
## Build from Source
### Prerequisites
See the [Build from Source](https://github.com/spring-projects/spring-framework/wiki/Build-from-Source) wiki page and the [CONTRIBUTING.md](CONTRIBUTING.md) file.
[Git][] and [JDK 8 update 20 or later][JDK8 build]
## Continuous Integration Builds
Be sure that your `JAVA_HOME` environment variable points to the `jdk1.8.0` folder
extracted from the JDK download.
Information regarding CI builds can be found in the [Spring Framework Concourse pipeline](ci/README.adoc) documentation.
### Check out sources
`git clone git@github.com:spring-projects/spring-framework.git`
## Stay in Touch
### Import sources into your IDE
Run `./import-into-eclipse.sh` or read `import-into-idea.md` as appropriate.
> **Note:** Per the prerequisites above, ensure that you have JDK 8 configured properly in your IDE.
Follow [@SpringCentral](https://twitter.com/springcentral), [@SpringFramework](https://twitter.com/springframework), and its [team members](https://twitter.com/springframework/lists/team/members) on 𝕏. In-depth articles can be found at [The Spring Blog](https://spring.io/blog/), and releases are announced via our [releases feed](https://spring.io/blog/category/releases).
### Install all spring-\* jars into your local Maven cache
`./gradlew install`
### Compile and test; build all jars, distribution zips, and docs
`./gradlew build`
... and discover more commands with `./gradlew tasks`. See also the [Gradle
build and release FAQ][].
## Contributing
[Pull requests][] are welcome; see the [contributor guidelines][] for details.

# Spring Framework Build
This folder contains the custom plugins and conventions for the Spring Framework build.
They are declared in the `build.gradle` file in this folder.
## Build Conventions
The `org.springframework.build.conventions` plugin applies all conventions to the Framework build:
* Configuring the Java compiler, see `JavaConventions`
* Configuring the Kotlin compiler, see `KotlinConventions`
* Configuring testing in the build with `TestConventions`
## Build Plugins
### Optional dependencies
The `org.springframework.build.optional-dependencies` plugin creates a new `optional`
Gradle configuration - it adds the dependencies to the project's compile and runtime classpath
but doesn't affect the classpath of dependent projects.
This plugin does not provide a `provided` configuration, as the native `compileOnly` and `testCompileOnly`
configurations are preferred.
### RuntimeHints Java Agent
The `spring-core-test` project module contributes the `RuntimeHintsAgent` Java agent.
The `RuntimeHintsAgentPlugin` Gradle plugin creates a dedicated `"runtimeHintsTest"` test task for each project.
This task will detect and execute [tests tagged](https://junit.org/junit5/docs/current/user-guide/#running-tests-build-gradle)
with the `"RuntimeHintsTests"` [JUnit tag](https://junit.org/junit5/docs/current/user-guide/#running-tests-tags).
In the Spring Framework test suite, those are usually annotated with the `@EnabledIfRuntimeHintsAgent` annotation.
By default, the agent will instrument all classes located in the `"org.springframework"` package, as they are loaded.
The `RuntimeHintsAgentExtension` allows to customize this using a DSL:
```groovy
// this applies the `RuntimeHintsAgentPlugin` to the project
plugins {
id 'org.springframework.build.runtimehints-agent'
}
// You can configure the agent to include and exclude packages from the instrumentation process.
runtimeHintsAgent {
includedPackages = ["org.springframework", "io.spring"]
excludedPackages = ["org.example"]
}
dependencies {
// to use the test infrastructure, the project should also depend on the "spring-core-test" module
testImplementation(project(":spring-core-test"))
}
```
With this configuration, `./gradlew runtimeHintsTest` will run all tests instrumented by this java agent.
The global `./gradlew check` task depends on `runtimeHintsTest`.
NOTE: the "spring-core-test" module doesn't shade "spring-core" by design, so the agent should never instrument
code that doesn't have "spring-core" on its classpath.

This part of the reference documentation covers topics that apply to multiple modules
within the core Spring Framework.
[[appendix-spring-properties]]
== Spring Properties
{spring-framework-api}/core/SpringProperties.html[`SpringProperties`] is a static holder
for properties that control certain low-level aspects of the Spring Framework. Users can
configure these properties via JVM system properties or programmatically via the
`SpringProperties.setProperty(String key, String value)` method. The latter may be
necessary if the deployment environment disallows custom JVM system properties. As an
alternative, these properties may be configured in a `spring.properties` file in the root
of the classpath -- for example, deployed within the application's JAR file.
The following table lists all currently supported Spring properties.

= Core Technologies
This part of the reference documentation covers all the technologies that are
absolutely integral to the Spring Framework.
Foremost amongst these is the Spring Framework's Inversion of Control (IoC) container.
A thorough treatment of the Spring Framework's IoC container is closely followed by
comprehensive coverage of Spring's Aspect-Oriented Programming (AOP) technologies.
The Spring Framework has its own AOP framework, which is conceptually easy to
understand and which successfully addresses the 80% sweet spot of AOP requirements
in Java enterprise programming.
Coverage of Spring's integration with AspectJ (currently the richest -- in terms of
features -- and certainly most mature AOP implementation in the Java enterprise space)
is also provided.
AOT processing can be used to optimize your application ahead-of-time. It is typically
used for native image deployment using GraalVM.

[[aop-api-advice]]
= Advice API in Spring
Now we can examine how Spring AOP handles advice.
[[aop-api-advice-lifecycle]]
== Advice Lifecycles
Each advice is a Spring bean. An advice instance can be shared across all advised
objects or be unique to each advised object. This corresponds to per-class or
per-instance advice.
Per-class advice is used most often. It is appropriate for generic advice, such as
transaction advisors. These do not depend on the state of the proxied object or add new
state. They merely act on the method and arguments.
Per-instance advice is appropriate for introductions, to support mixins. In this case,
the advice adds state to the proxied object.
You can use a mix of shared and per-instance advice in the same AOP proxy.
[[aop-api-advice-types]]
== Advice Types in Spring
Spring provides several advice types and is extensible to support
arbitrary advice types. This section describes the basic concepts and standard advice types.
[[aop-api-advice-around]]
=== Interception Around Advice
The most fundamental advice type in Spring is interception around advice.
Spring is compliant with the AOP `Alliance` interface for around advice that uses method
interception. Classes that implement `MethodInterceptor` and that implement around advice should also implement the
following interface:
[source,java,indent=0,subs="verbatim,quotes"]
----
public interface MethodInterceptor extends Interceptor {
Object invoke(MethodInvocation invocation) throws Throwable;
}
----
The `MethodInvocation` argument to the `invoke()` method exposes the method being
invoked, the target join point, the AOP proxy, and the arguments to the method. The
`invoke()` method should return the invocation's result: the return value of the join
point.
The following example shows a simple `MethodInterceptor` implementation:
[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim,quotes",role="primary"]
----
public class DebugInterceptor implements MethodInterceptor {
public Object invoke(MethodInvocation invocation) throws Throwable {
System.out.println("Before: invocation=[" + invocation + "]");
Object rval = invocation.proceed();
System.out.println("Invocation returned");
return rval;
}
}
----
Kotlin::
+
[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
----
class DebugInterceptor : MethodInterceptor {
override fun invoke(invocation: MethodInvocation): Any {
println("Before: invocation=[$invocation]")
val rval = invocation.proceed()
println("Invocation returned")
return rval
}
}
----
======
Note the call to the `proceed()` method of `MethodInvocation`. This proceeds down the
interceptor chain towards the join point. Most interceptors invoke this method and
return its return value. However, a `MethodInterceptor`, like any around advice, can
return a different value or throw an exception rather than invoke the proceed method.
However, you do not want to do this without good reason.
NOTE: `MethodInterceptor` implementations offer interoperability with other AOP Alliance-compliant AOP
implementations. The other advice types discussed in the remainder of this section
implement common AOP concepts but in a Spring-specific way. While there is an advantage
in using the most specific advice type, stick with `MethodInterceptor` around advice if
you are likely to want to run the aspect in another AOP framework. Note that pointcuts
are not currently interoperable between frameworks, and the AOP Alliance does not
currently define pointcut interfaces.
[[aop-api-advice-before]]
=== Before Advice
A simpler advice type is a before advice. This does not need a `MethodInvocation`
object, since it is called only before entering the method.
The main advantage of a before advice is that there is no need to invoke the `proceed()`
method and, therefore, no possibility of inadvertently failing to proceed down the
interceptor chain.
The following listing shows the `MethodBeforeAdvice` interface:
[source,java,indent=0,subs="verbatim,quotes"]
----
public interface MethodBeforeAdvice extends BeforeAdvice {
void before(Method m, Object[] args, Object target) throws Throwable;
}
----
(Spring's API design would allow for
field before advice, although the usual objects apply to field interception and it is
unlikely for Spring to ever implement it.)
Note that the return type is `void`. Before advice can insert custom behavior before the join
point runs but cannot change the return value. If a before advice throws an
exception, it stops further execution of the interceptor chain. The exception
propagates back up the interceptor chain. If it is unchecked or on the signature of
the invoked method, it is passed directly to the client. Otherwise, it is
wrapped in an unchecked exception by the AOP proxy.
The following example shows a before advice in Spring, which counts all method invocations:
[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim,quotes",role="primary"]
----
public class CountingBeforeAdvice implements MethodBeforeAdvice {
private int count;
public void before(Method m, Object[] args, Object target) throws Throwable {
++count;
}
public int getCount() {
return count;
}
}
----
Kotlin::
+
[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
----
class CountingBeforeAdvice : MethodBeforeAdvice {
var count: Int = 0
override fun before(m: Method, args: Array<Any>, target: Any?) {
++count
}
}
----
======
TIP: Before advice can be used with any pointcut.
[[aop-api-advice-throws]]
=== Throws Advice
Throws advice is invoked after the return of the join point if the join point threw
an exception. Spring offers typed throws advice. Note that this means that the
`org.springframework.aop.ThrowsAdvice` interface does not contain any methods. It is a
tag interface identifying that the given object implements one or more typed throws
advice methods. These should be in the following form:
[source,java,indent=0,subs="verbatim,quotes"]
----
afterThrowing([Method, args, target], subclassOfThrowable)
----
Only the last argument is required. The method signatures may have either one or four
arguments, depending on whether the advice method is interested in the method and
arguments. The next two listing show classes that are examples of throws advice.
The following advice is invoked if a `RemoteException` is thrown (including from subclasses):
[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim,quotes",role="primary"]
----
public class RemoteThrowsAdvice implements ThrowsAdvice {
public void afterThrowing(RemoteException ex) throws Throwable {
// Do something with remote exception
}
}
----
Kotlin::
+
[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
----
class RemoteThrowsAdvice : ThrowsAdvice {
fun afterThrowing(ex: RemoteException) {
// Do something with remote exception
}
}
----
======
Unlike the preceding
advice, the next example declares four arguments, so that it has access to the invoked method, method
arguments, and target object. The following advice is invoked if a `ServletException` is thrown:
[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim,quotes",role="primary"]
----
public class ServletThrowsAdviceWithArguments implements ThrowsAdvice {
public void afterThrowing(Method m, Object[] args, Object target, ServletException ex) {
// Do something with all arguments
}
}
----
Kotlin::
+
[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
----
class ServletThrowsAdviceWithArguments : ThrowsAdvice {
fun afterThrowing(m: Method, args: Array<Any>, target: Any, ex: ServletException) {
// Do something with all arguments
}
}
----
======
The final example illustrates how these two methods could be used in a single class
that handles both `RemoteException` and `ServletException`. Any number of throws advice
methods can be combined in a single class. The following listing shows the final example:
[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim,quotes",role="primary"]
----
public static class CombinedThrowsAdvice implements ThrowsAdvice {
public void afterThrowing(RemoteException ex) throws Throwable {
// Do something with remote exception
}
public void afterThrowing(Method m, Object[] args, Object target, ServletException ex) {
// Do something with all arguments
}
}
----
Kotlin::
+
[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
----
class CombinedThrowsAdvice : ThrowsAdvice {
fun afterThrowing(ex: RemoteException) {
// Do something with remote exception
}
fun afterThrowing(m: Method, args: Array<Any>, target: Any, ex: ServletException) {
// Do something with all arguments
}
}
----
======
NOTE: If a throws-advice method throws an exception itself, it overrides the
original exception (that is, it changes the exception thrown to the user). The overriding
exception is typically a RuntimeException, which is compatible with any method
signature. However, if a throws-advice method throws a checked exception, it must
match the declared exceptions of the target method and is, hence, to some degree
coupled to specific target method signatures. _Do not throw an undeclared checked
exception that is incompatible with the target method's signature!_
TIP: Throws advice can be used with any pointcut.
[[aop-api-advice-after-returning]]
=== After Returning Advice
An after returning advice in Spring must implement the
`org.springframework.aop.AfterReturningAdvice` interface, which the following listing shows:
[source,java,indent=0,subs="verbatim,quotes"]
----
public interface AfterReturningAdvice extends Advice {
void afterReturning(Object returnValue, Method m, Object[] args, Object target)
throws Throwable;
}
----
An after returning advice has access to the return value (which it cannot modify),
the invoked method, the method's arguments, and the target.
The following after returning advice counts all successful method invocations that have
not thrown exceptions:
[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim,quotes",role="primary"]
----
public class CountingAfterReturningAdvice implements AfterReturningAdvice {
private int count;
public void afterReturning(Object returnValue, Method m, Object[] args, Object target)
throws Throwable {
++count;
}
public int getCount() {
return count;
}
}
----
Kotlin::
+
[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
----
class CountingAfterReturningAdvice : AfterReturningAdvice {
var count: Int = 0
private set
override fun afterReturning(returnValue: Any?, m: Method, args: Array<Any>, target: Any?) {
++count
}
}
----
======
This advice does not change the execution path. If it throws an exception, it is
thrown up the interceptor chain instead of the return value.
TIP: After returning advice can be used with any pointcut.
[[aop-api-advice-introduction]]
=== Introduction Advice
Spring treats introduction advice as a special kind of interception advice.
Introduction requires an `IntroductionAdvisor` and an `IntroductionInterceptor` that
implement the following interface:
[source,java,indent=0,subs="verbatim,quotes"]
----
public interface IntroductionInterceptor extends MethodInterceptor {
boolean implementsInterface(Class intf);
}
----
The `invoke()` method inherited from the AOP Alliance `MethodInterceptor` interface must
implement the introduction. That is, if the invoked method is on an introduced
interface, the introduction interceptor is responsible for handling the method call -- it
cannot invoke `proceed()`.
Introduction advice cannot be used with any pointcut, as it applies only at the class,
rather than the method, level. You can only use introduction advice with the
`IntroductionAdvisor`, which has the following methods:
[source,java,indent=0,subs="verbatim,quotes"]
----
public interface IntroductionAdvisor extends Advisor, IntroductionInfo {
ClassFilter getClassFilter();
void validateInterfaces() throws IllegalArgumentException;
}
public interface IntroductionInfo {
Class<?>[] getInterfaces();
}
----
There is no `MethodMatcher` and, hence, no `Pointcut` associated with introduction
advice. Only class filtering is logical.
The `getInterfaces()` method returns the interfaces introduced by this advisor.
The `validateInterfaces()` method is used internally to see whether or not the
introduced interfaces can be implemented by the configured `IntroductionInterceptor`.
Consider an example from the Spring test suite and suppose we want to
introduce the following interface to one or more objects:
[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim,quotes",role="primary"]
----
public interface Lockable {
void lock();
void unlock();
boolean locked();
}
----
Kotlin::
+
[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
----
interface Lockable {
fun lock()
fun unlock()
fun locked(): Boolean
}
----
======
This illustrates a mixin. We want to be able to cast advised objects to `Lockable`,
whatever their type and call lock and unlock methods. If we call the `lock()` method, we
want all setter methods to throw a `LockedException`. Thus, we can add an aspect that
provides the ability to make objects immutable without them having any knowledge of it:
a good example of AOP.
First, we need an `IntroductionInterceptor` that does the heavy lifting. In this
case, we extend the `org.springframework.aop.support.DelegatingIntroductionInterceptor`
convenience class. We could implement `IntroductionInterceptor` directly, but using
`DelegatingIntroductionInterceptor` is best for most cases.
The `DelegatingIntroductionInterceptor` is designed to delegate an introduction to an
actual implementation of the introduced interfaces, concealing the use of interception
to do so. You can set the delegate to any object using a constructor argument. The
default delegate (when the no-argument constructor is used) is `this`. Thus, in the next example,
the delegate is the `LockMixin` subclass of `DelegatingIntroductionInterceptor`.
Given a delegate (by default, itself), a `DelegatingIntroductionInterceptor` instance
looks for all interfaces implemented by the delegate (other than
`IntroductionInterceptor`) and supports introductions against any of them.
Subclasses such as `LockMixin` can call the `suppressInterface(Class intf)`
method to suppress interfaces that should not be exposed. However, no matter how many
interfaces an `IntroductionInterceptor` is prepared to support, the
`IntroductionAdvisor` used controls which interfaces are actually exposed. An
introduced interface conceals any implementation of the same interface by the target.
Thus, `LockMixin` extends `DelegatingIntroductionInterceptor` and implements `Lockable`
itself. The superclass automatically picks up that `Lockable` can be supported for
introduction, so we do not need to specify that. We could introduce any number of
interfaces in this way.
Note the use of the `locked` instance variable. This effectively adds additional state
to that held in the target object.
The following example shows the example `LockMixin` class:
[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim,quotes",role="primary"]
----
public class LockMixin extends DelegatingIntroductionInterceptor implements Lockable {
private boolean locked;
public void lock() {
this.locked = true;
}
public void unlock() {
this.locked = false;
}
public boolean locked() {
return this.locked;
}
public Object invoke(MethodInvocation invocation) throws Throwable {
if (locked() && invocation.getMethod().getName().indexOf("set") == 0) {
throw new LockedException();
}
return super.invoke(invocation);
}
}
----
Kotlin::
+
[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
----
class LockMixin : DelegatingIntroductionInterceptor(), Lockable {
private var locked: Boolean = false
fun lock() {
this.locked = true
}
fun unlock() {
this.locked = false
}
fun locked(): Boolean {
return this.locked
}
override fun invoke(invocation: MethodInvocation): Any? {
if (locked() && invocation.method.name.indexOf("set") == 0) {
throw LockedException()
}
return super.invoke(invocation)
}
}
----
======
Often, you need not override the `invoke()` method. The
`DelegatingIntroductionInterceptor` implementation (which calls the `delegate` method if
the method is introduced, otherwise proceeds towards the join point) usually
suffices. In the present case, we need to add a check: no setter method can be invoked
if in locked mode.
The required introduction only needs to hold a distinct
`LockMixin` instance and specify the introduced interfaces (in this case, only
`Lockable`). A more complex example might take a reference to the introduction
interceptor (which would be defined as a prototype). In this case, there is no
configuration relevant for a `LockMixin`, so we create it by using `new`.
The following example shows our `LockMixinAdvisor` class:
[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim,quotes",role="primary"]
----
public class LockMixinAdvisor extends DefaultIntroductionAdvisor {
public LockMixinAdvisor() {
super(new LockMixin(), Lockable.class);
}
}
----
Kotlin::
+
[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
----
class LockMixinAdvisor : DefaultIntroductionAdvisor(LockMixin(), Lockable::class.java)
----
======
We can apply this advisor very simply, because it requires no configuration. (However, it
is impossible to use an `IntroductionInterceptor` without an
`IntroductionAdvisor`.) As usual with introductions, the advisor must be per-instance,
as it is stateful. We need a different instance of `LockMixinAdvisor`, and hence
`LockMixin`, for each advised object. The advisor comprises part of the advised object's
state.
We can apply this advisor programmatically by using the `Advised.addAdvisor()` method or
(the recommended way) in XML configuration, as any other advisor. All proxy creation
choices discussed below, including "`auto proxy creators,`" correctly handle introductions
and stateful mixins.

[[aop-api-advised]]
= Manipulating Advised Objects
However you create AOP proxies, you can manipulate them BY using the

interface, no matter which other interfaces it implements. This interface includes the
following methods:

fun replaceAdvisor(a: Advisor, b: Advisor): Boolean
fun isFrozen(): Boolean
----
======
The `getAdvisors()` method returns an `Advisor` for every advisor, interceptor, or
other advice type that has been added to the factory. If you added an `Advisor`, the
returned advisor at this index is the object that you added. If you added an
interceptor or other advice type, Spring wrapped this in an advisor with a
pointcut that always returns `true`. Thus, if you added a `MethodInterceptor`, the advisor
returned for this index is a `DefaultPointcutAdvisor` that returns your
`MethodInterceptor` and a pointcut that matches all classes and methods.
The `addAdvisor()` methods can be used to add any `Advisor`. Usually, the advisor holding
pointcut and advice is the generic `DefaultPointcutAdvisor`, which you can use with
any advice or pointcut (but not for introductions).
By default, it is possible to add or remove advisors or interceptors even once a proxy
has been created. The only restriction is that it is impossible to add or remove an
introduction advisor, as existing proxies from the factory do not show the interface
change. (You can obtain a new proxy from the factory to avoid this problem.)
The following example shows casting an AOP proxy to the `Advised` interface and examining and
manipulating its advice:
[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim,quotes",role="primary"]
----
Advised advised = (Advised) myObject;
Advisor[] advisors = advised.getAdvisors();
int oldAdvisorCount = advisors.length;
System.out.println(oldAdvisorCount + " advisors");
// Add an advice like an interceptor without a pointcut
// Will match all proxied methods
// Can use for interceptors, before, after returning or throws advice
advised.addAdvice(new DebugInterceptor());
// Add selective advice using a pointcut
advised.addAdvisor(new DefaultPointcutAdvisor(mySpecialPointcut, myAdvice));
assertEquals("Added two advisors", oldAdvisorCount + 2, advised.getAdvisors().length);
----

// Can use for interceptors, before, after returning or throws advice
advised.addAdvice(DebugInterceptor())
// Add selective advice using a pointcut
advised.addAdvisor(DefaultPointcutAdvisor(mySpecialPointcut, myAdvice))
assertEquals("Added two advisors", oldAdvisorCount + 2, advised.advisors.size)
----
======
NOTE: It is questionable whether it is advisable (no pun intended) to modify advice on a
business object in production, although there are, no doubt, legitimate usage cases.
However, it can be very useful in development (for example, in tests). We have sometimes
found it very useful to be able to add test code in the form of an interceptor or other
advice, getting inside a method invocation that we want to test. (For example, the advice can
get inside a transaction created for that method, perhaps to run SQL to check that
a database was correctly updated, before marking the transaction for roll back.)
Depending on how you created the proxy, you can usually set a `frozen` flag. In that
case, the `Advised` `isFrozen()` method returns `true`, and any attempts to modify
advice through addition or removal results in an `AopConfigException`. The ability
to freeze the state of an advised object is useful in some cases (for example, to
prevent calling code removing a security interceptor).

[[aop-autoproxy]]
= Using the "auto-proxy" facility
So far, we have considered explicit creation of AOP proxies by using a `ProxyFactoryBean` or
similar factory bean.
Spring also lets us use "`auto-proxy`" bean definitions, which can automatically
proxy selected bean definitions. This is built on Spring's "`bean post processor`"
infrastructure, which enables modification of any bean definition as the container loads.
In this model, you set up some special bean definitions in your XML bean definition file
to configure the auto-proxy infrastructure. This lets you declare the targets
eligible for auto-proxying. You need not use `ProxyFactoryBean`.
There are two ways to do this:
* By using an auto-proxy creator that refers to specific beans in the current context.
* A special case of auto-proxy creation that deserves to be considered separately:
auto-proxy creation driven by source-level metadata attributes.
[[aop-autoproxy-choices]]
== Auto-proxy Bean Definitions
This section covers the auto-proxy creators provided by the
`org.springframework.aop.framework.autoproxy` package.
[[aop-api-autoproxy]]
=== `BeanNameAutoProxyCreator`
The `BeanNameAutoProxyCreator` class is a `BeanPostProcessor` that automatically creates
AOP proxies for beans with names that match literal values or wildcards. The following
example shows how to create a `BeanNameAutoProxyCreator` bean:
[source,xml,indent=0,subs="verbatim,quotes"]
----
<bean class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator">
<property name="beanNames" value="jdk*,onlyJdk"/>
<property name="interceptorNames">
<list>
<value>myInterceptor</value>
</list>
</property>
</bean>
----
As with `ProxyFactoryBean`, there is an `interceptorNames` property rather than a list
of interceptors, to allow correct behavior for prototype advisors. Named "`interceptors`"
can be advisors or any advice type.
As with auto-proxying in general, the main point of using `BeanNameAutoProxyCreator` is
to apply the same configuration consistently to multiple objects, with minimal volume of
configuration. It is a popular choice for applying declarative transactions to multiple
objects.
Bean definitions whose names match, such as `jdkMyBean` and `onlyJdk` in the preceding
example, are plain old bean definitions with the target class. An AOP proxy is
automatically created by the `BeanNameAutoProxyCreator`. The same advice is applied
to all matching beans. Note that, if advisors are used (rather than the interceptor in
the preceding example), the pointcuts may apply differently to different beans.
[[aop-api-autoproxy-default]]
=== `DefaultAdvisorAutoProxyCreator`
A more general and extremely powerful auto-proxy creator is
`DefaultAdvisorAutoProxyCreator`. This automagically applies eligible advisors in the
current context, without the need to include specific bean names in the auto-proxy
advisor's bean definition. It offers the same merit of consistent configuration and
avoidance of duplication as `BeanNameAutoProxyCreator`.
Using this mechanism involves:
* Specifying a `DefaultAdvisorAutoProxyCreator` bean definition.
* Specifying any number of advisors in the same or related contexts. Note that these
must be advisors, not interceptors or other advice. This is necessary,
because there must be a pointcut to evaluate, to check the eligibility of each advice
to candidate bean definitions.
The `DefaultAdvisorAutoProxyCreator` automatically evaluates the pointcut contained
in each advisor, to see what (if any) advice it should apply to each business object
(such as `businessObject1` and `businessObject2` in the example).
This means that any number of advisors can be applied automatically to each business
object. If no pointcut in any of the advisors matches any method in a business object,
the object is not proxied. As bean definitions are added for new business objects,
they are automatically proxied if necessary.
Auto-proxying in general has the advantage of making it impossible for callers or
dependencies to obtain an un-advised object. Calling `getBean("businessObject1")` on this
`ApplicationContext` returns an AOP proxy, not the target business object. (The "`inner
bean`" idiom shown earlier also offers this benefit.)
The following example creates a `DefaultAdvisorAutoProxyCreator` bean and the other
elements discussed in this section:
[source,xml,indent=0,subs="verbatim,quotes"]
----
<bean class="org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator"/>
<bean class="org.springframework.transaction.interceptor.TransactionAttributeSourceAdvisor">
<property name="transactionInterceptor" ref="transactionInterceptor"/>
</bean>
<bean id="customAdvisor" class="com.mycompany.MyAdvisor"/>
<bean id="businessObject1" class="com.mycompany.BusinessObject1">
<!-- Properties omitted -->
</bean>
<bean id="businessObject2" class="com.mycompany.BusinessObject2"/>
----
The `DefaultAdvisorAutoProxyCreator` is very useful if you want to apply the same advice
consistently to many business objects. Once the infrastructure definitions are in place,
you can add new business objects without including specific proxy configuration.
You can also easily drop in additional aspects (for example, tracing or
performance monitoring aspects) with minimal change to configuration.
The `DefaultAdvisorAutoProxyCreator` offers support for filtering (by using a naming
convention so that only certain advisors are evaluated, which allows the use of multiple,
differently configured, AdvisorAutoProxyCreators in the same factory) and ordering.
Advisors can implement the `org.springframework.core.Ordered` interface to ensure
correct ordering if this is an issue. The `TransactionAttributeSourceAdvisor` used in the
preceding example has a configurable order value. The default setting is unordered.

[[aop-concise-proxy]]
= Concise Proxy Definitions
Especially when defining transactional proxies, you may end up with many similar proxy
definitions. The use of parent and child bean definitions, along with inner bean
definitions, can result in much cleaner and more concise proxy definitions.
First, we create a parent, template, bean definition for the proxy, as follows:
[source,xml,indent=0,subs="verbatim,quotes"]
----
<bean id="txProxyTemplate" abstract="true"
class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
<property name="transactionManager" ref="transactionManager"/>
<property name="transactionAttributes">
<props>
<prop key="*">PROPAGATION_REQUIRED</prop>
</props>
</property>
</bean>
----
This is never instantiated itself, so it can actually be incomplete. Then, each proxy
that needs to be created is a child bean definition, which wraps the target of the
proxy as an inner bean definition, since the target is never used on its own anyway.
The following example shows such a child bean:
[source,xml,indent=0,subs="verbatim,quotes"]
----
<bean id="myService" parent="txProxyTemplate">
<property name="target">
<bean class="org.springframework.samples.MyServiceImpl">
</bean>
</property>
</bean>
----
You can override properties from the parent template. In the following example,
we override the transaction propagation settings:
[source,xml,indent=0,subs="verbatim,quotes"]
----
<bean id="mySpecialService" parent="txProxyTemplate">
<property name="target">
<bean class="org.springframework.samples.MySpecialServiceImpl">
</bean>
</property>
<property name="transactionAttributes">
<props>
<prop key="get*">PROPAGATION_REQUIRED,readOnly</prop>
<prop key="find*">PROPAGATION_REQUIRED,readOnly</prop>
<prop key="load*">PROPAGATION_REQUIRED,readOnly</prop>
<prop key="store*">PROPAGATION_REQUIRED</prop>
</props>
</property>
</bean>
----
Note that in the parent bean example, we explicitly marked the parent bean definition as
being abstract by setting the `abstract` attribute to `true`, as described
xref:core/beans/child-bean-definitions.adoc[previously], so that it may not actually ever be
instantiated. Application contexts (but not simple bean factories), by default,
pre-instantiate all singletons. Therefore, it is important (at least for singleton beans)
that, if you have a (parent) bean definition that you intend to use only as a template,
and this definition specifies a class, you must make sure to set the `abstract`
attribute to `true`. Otherwise, the application context actually tries to
pre-instantiate it.

= Using the `ProxyFactoryBean` to Create AOP Proxies
If you use the Spring IoC container (an `ApplicationContext` or `BeanFactory`) for your
business objects (and you should be!), you want to use one of Spring's AOP
`FactoryBean` implementations. (Remember that a factory bean introduces a layer of indirection, letting
it create objects of a different type.)
NOTE: The Spring AOP support also uses factory beans under the covers.
The basic way to create an AOP proxy in Spring is to use the
`org.springframework.aop.framework.ProxyFactoryBean`. This gives complete control over
the pointcuts, any advice that applies, and their ordering. However, there are simpler
options that are preferable if you do not need such control.
[[aop-pfb-1]]
== Basics
The `ProxyFactoryBean`, like other Spring `FactoryBean` implementations, introduces a
level of indirection. If you define a `ProxyFactoryBean` named `foo`, objects that
reference `foo` do not see the `ProxyFactoryBean` instance itself but an object
created by the implementation of the `getObject()` method in the `ProxyFactoryBean` . This
method creates an AOP proxy that wraps a target object.
One of the most important benefits of using a `ProxyFactoryBean` or another IoC-aware
class to create AOP proxies is that advice and pointcuts can also be
managed by IoC. This is a powerful feature, enabling certain approaches that are hard to
achieve with other AOP frameworks. For example, an advice may itself reference
application objects (besides the target, which should be available in any AOP
framework), benefiting from all the pluggability provided by Dependency Injection.
[[aop-pfb-2]]
== JavaBean Properties
In common with most `FactoryBean` implementations provided with Spring, the
`ProxyFactoryBean` class is itself a JavaBean. Its properties are used to:
* Specify the target you want to proxy.
* Specify whether to use CGLIB (described later and see also xref:core/aop-api/pfb.adoc#aop-pfb-proxy-types[JDK- and CGLIB-based proxies]).
Some key properties are inherited from `org.springframework.aop.framework.ProxyConfig`
(the superclass for all AOP proxy factories in Spring). These key properties include
the following:
* `proxyTargetClass`: `true` if the target class is to be proxied, rather than the
target class's interfaces. If this property value is set to `true`, then CGLIB proxies
are created (but see also xref:core/aop-api/pfb.adoc#aop-pfb-proxy-types[JDK- and CGLIB-based proxies]).
* `optimize`: Controls whether or not aggressive optimizations are applied to proxies
created through CGLIB. You should not blithely use this setting unless you fully
understand how the relevant AOP proxy handles optimization. This is currently used
only for CGLIB proxies. It has no effect with JDK dynamic proxies.
* `frozen`: If a proxy configuration is `frozen`, changes to the configuration are
no longer allowed. This is useful both as a slight optimization and for those cases
when you do not want callers to be able to manipulate the proxy (through the `Advised`
interface) after the proxy has been created. The default value of this property is
`false`, so changes (such as adding additional advice) are allowed.
* `exposeProxy`: Determines whether or not the current proxy should be exposed in a
`ThreadLocal` so that it can be accessed by the target. If a target needs to obtain
the proxy and the `exposeProxy` property is set to `true`, the target can use the
`AopContext.currentProxy()` method.
Other properties specific to `ProxyFactoryBean` include the following:
* `proxyInterfaces`: An array of `String` interface names. If this is not supplied, a CGLIB
proxy for the target class is used (but see also xref:core/aop-api/pfb.adoc#aop-pfb-proxy-types[JDK- and CGLIB-based proxies]).
* `interceptorNames`: A `String` array of `Advisor`, interceptor, or other advice names to
apply. Ordering is significant, on a first come-first served basis. That is to say
that the first interceptor in the list is the first to be able to intercept the
invocation.
+
The names are bean names in the current factory, including bean names from ancestor
factories. You cannot mention bean references here, since doing so results in the
`ProxyFactoryBean` ignoring the singleton setting of the advice.
+
You can append an interceptor name with an asterisk (`*`). Doing so results in the
application of all advisor beans with names that start with the part before the asterisk
to be applied. You can find an example of using this feature in xref:core/aop-api/pfb.adoc#aop-global-advisors[Using "`Global`" Advisors].
* singleton: Whether or not the factory should return a single object, no matter how
often the `getObject()` method is called. Several `FactoryBean` implementations offer
such a method. The default value is `true`. If you want to use stateful advice - for
example, for stateful mixins - use prototype advice along with a singleton value of
`false`.
[[aop-pfb-proxy-types]]
== JDK- and CGLIB-based proxies
This section serves as the definitive documentation on how the `ProxyFactoryBean`
chooses to create either a JDK-based proxy or a CGLIB-based proxy for a particular target
object (which is to be proxied).
NOTE: The behavior of the `ProxyFactoryBean` with regard to creating JDK- or CGLIB-based
proxies changed between versions 1.2.x and 2.0 of Spring. The `ProxyFactoryBean` now
exhibits similar semantics with regard to auto-detecting interfaces as those of the
`TransactionProxyFactoryBean` class.
If the class of a target object that is to be proxied (hereafter simply referred to as
the target class) does not implement any interfaces, a CGLIB-based proxy is
created. This is the easiest scenario, because JDK proxies are interface-based, and no
interfaces means JDK proxying is not even possible. You can plug in the target bean
and specify the list of interceptors by setting the `interceptorNames` property. Note that a
CGLIB-based proxy is created even if the `proxyTargetClass` property of the
`ProxyFactoryBean` has been set to `false`. (Doing so makes no sense and is best
removed from the bean definition, because it is, at best, redundant, and, at worst
confusing.)
If the target class implements one (or more) interfaces, the type of proxy that is
created depends on the configuration of the `ProxyFactoryBean`.
If the `proxyTargetClass` property of the `ProxyFactoryBean` has been set to `true`,
a CGLIB-based proxy is created. This makes sense and is in keeping with the
principle of least surprise. Even if the `proxyInterfaces` property of the
`ProxyFactoryBean` has been set to one or more fully qualified interface names, the fact
that the `proxyTargetClass` property is set to `true` causes CGLIB-based
proxying to be in effect.
If the `proxyInterfaces` property of the `ProxyFactoryBean` has been set to one or more
fully qualified interface names, a JDK-based proxy is created. The created
proxy implements all of the interfaces that were specified in the `proxyInterfaces`
property. If the target class happens to implement a whole lot more interfaces than
those specified in the `proxyInterfaces` property, that is all well and good, but those
additional interfaces are not implemented by the returned proxy.
If the `proxyInterfaces` property of the `ProxyFactoryBean` has not been set, but
the target class does implement one (or more) interfaces, the
`ProxyFactoryBean` auto-detects the fact that the target class does actually
implement at least one interface, and a JDK-based proxy is created. The interfaces
that are actually proxied are all of the interfaces that the target class
implements. In effect, this is the same as supplying a list of each and every
interface that the target class implements to the `proxyInterfaces` property. However,
it is significantly less work and less prone to typographical errors.
[[aop-api-proxying-intf]]
== Proxying Interfaces
Consider a simple example of `ProxyFactoryBean` in action. This example involves:
* A target bean that is proxied. This is the `personTarget` bean definition in
the example.
* An `Advisor` and an `Interceptor` used to provide advice.
* An AOP proxy bean definition to specify the target object (the `personTarget` bean),
the interfaces to proxy, and the advice to apply.
The following listing shows the example:
[source,xml,indent=0,subs="verbatim,quotes"]
----
<bean id="personTarget" class="com.mycompany.PersonImpl">
<property name="name" value="Tony"/>
<property name="age" value="51"/>
</bean>
<bean id="myAdvisor" class="com.mycompany.MyAdvisor">
<property name="someProperty" value="Custom string property value"/>
</bean>
<bean id="debugInterceptor" class="org.springframework.aop.interceptor.DebugInterceptor">
</bean>
<bean id="person"
class="org.springframework.aop.framework.ProxyFactoryBean">
<property name="proxyInterfaces" value="com.mycompany.Person"/>
<property name="target" ref="personTarget"/>
<property name="interceptorNames">
<list>
<value>myAdvisor</value>
<value>debugInterceptor</value>
</list>
</property>
</bean>
----
Note that the `interceptorNames` property takes a list of `String`, which holds the bean names of the
interceptors or advisors in the current factory. You can use advisors, interceptors, before, after
returning, and throws advice objects. The ordering of advisors is significant.
NOTE: You might be wondering why the list does not hold bean references. The reason for this is
that, if the singleton property of the `ProxyFactoryBean` is set to `false`, it must be able to
return independent proxy instances. If any of the advisors is itself a prototype, an
independent instance would need to be returned, so it is necessary to be able to obtain
an instance of the prototype from the factory. Holding a reference is not sufficient.
The `person` bean definition shown earlier can be used in place of a `Person` implementation, as
follows:
[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim,quotes",role="primary"]
----

----
Kotlin::
+

----
val person = factory.getBean("person") as Person;

======
Other beans in the same IoC context can express a strongly typed dependency on it, as
with an ordinary Java object. The following example shows how to do so:
[source,xml,indent=0,subs="verbatim,quotes"]
----
<bean id="personUser" class="com.mycompany.PersonUser">
<property name="person"><ref bean="person"/></property>

The `PersonUser` class in this example exposes a property of type `Person`. As far as
it is concerned, the AOP proxy can be used transparently in place of a "`real`" person
implementation. However, its class would be a dynamic proxy class. It would be possible
to cast it to the `Advised` interface (discussed later).
You can conceal the distinction between target and proxy by using an anonymous
inner bean. Only the `ProxyFactoryBean` definition is different. The
advice is included only for completeness. The following example shows how to use an
anonymous inner bean:
[source,xml,indent=0,subs="verbatim,quotes"]
----
<bean id="myAdvisor" class="com.mycompany.MyAdvisor">
<property name="someProperty" value="Custom string property value"/>
</bean>
<bean id="debugInterceptor" class="org.springframework.aop.interceptor.DebugInterceptor"/>
<bean id="person" class="org.springframework.aop.framework.ProxyFactoryBean">
<property name="proxyInterfaces" value="com.mycompany.Person"/>
<!-- Use inner bean, not local reference to target -->
<property name="target">
<bean class="com.mycompany.PersonImpl">
<property name="name" value="Tony"/>
<property name="age" value="51"/>
</bean>
</property>
<property name="interceptorNames">
<list>
<value>myAdvisor</value>
<value>debugInterceptor</value>
</list>
</property>
</bean>
----
Using an anonymous inner bean has the advantage that there is only one object of type `Person`. This is useful if we want
to prevent users of the application context from obtaining a reference to the un-advised
object or need to avoid any ambiguity with Spring IoC autowiring. There is also,
arguably, an advantage in that the `ProxyFactoryBean` definition is self-contained.
However, there are times when being able to obtain the un-advised target from the
factory might actually be an advantage (for example, in certain test scenarios).
[[aop-api-proxying-class]]
== Proxying Classes
What if you need to proxy a class, rather than one or more interfaces?
Imagine that in our earlier example, there was no `Person` interface. We needed to advise
a class called `Person` that did not implement any business interface. In this case, you
can configure Spring to use CGLIB proxying rather than dynamic proxies. To do so, set the
`proxyTargetClass` property on the `ProxyFactoryBean` shown earlier to `true`. While it is best to
program to interfaces rather than classes, the ability to advise classes that do not
implement interfaces can be useful when working with legacy code. (In general, Spring
is not prescriptive. While it makes it easy to apply good practices, it avoids forcing a
particular approach.)
If you want to, you can force the use of CGLIB in any case, even if you do have
interfaces.
CGLIB proxying works by generating a subclass of the target class at runtime. Spring
configures this generated subclass to delegate method calls to the original target. The
subclass is used to implement the Decorator pattern, weaving in the advice.
CGLIB proxying should generally be transparent to users. However, there are some issues
to consider:
* `final` classes cannot be proxied, because they cannot be extended.
* `final` methods cannot be advised, because they cannot be overridden.
* `private` methods cannot be advised, because they cannot be overridden.
* Methods that are not visible, typically package private methods in a parent class
from a different package, cannot be advised because they are effectively private.
NOTE: There is no need to add CGLIB to your classpath. CGLIB is repackaged and included
in the `spring-core` JAR. In other words, CGLIB-based AOP works "out of the box", as do
JDK dynamic proxies.
There is little performance difference between CGLIB proxies and dynamic proxies.
Performance should not be a decisive consideration in this case.
[[aop-global-advisors]]
== Using "`Global`" Advisors
By appending an asterisk to an interceptor name, all advisors with bean names that match
the part before the asterisk are added to the advisor chain. This can come in handy
if you need to add a standard set of "`global`" advisors. The following example defines
two global advisors:

[[aop-api-pointcuts]]
= Pointcut API in Spring
This section describes how Spring handles the crucial pointcut concept.
[[aop-api-concepts]]
== Concepts
Spring's pointcut model enables pointcut reuse independent of advice types. You can
target different advice with the same pointcut.
The `org.springframework.aop.Pointcut` interface is the central interface, used to
target advice to particular classes and methods. The complete interface follows:
[source,java,indent=0,subs="verbatim,quotes"]
----
public interface Pointcut {
ClassFilter getClassFilter();
MethodMatcher getMethodMatcher();
}
----
Splitting the `Pointcut` interface into two parts allows reuse of class and method
matching parts and fine-grained composition operations (such as performing a "`union`"
with another method matcher).
The `ClassFilter` interface is used to restrict the pointcut to a given set of target
classes. If the `matches()` method always returns true, all target classes are
matched. The following listing shows the `ClassFilter` interface definition:
[source,java,indent=0,subs="verbatim,quotes"]
----
public interface ClassFilter {
boolean matches(Class clazz);
}
----
The `MethodMatcher` interface is normally more important. The complete interface follows:
[source,java,indent=0,subs="verbatim,quotes"]
----
public interface MethodMatcher {
boolean matches(Method m, Class<?> targetClass);
boolean isRuntime();
boolean matches(Method m, Class<?> targetClass, Object... args);
}
----
The `matches(Method, Class)` method is used to test whether this pointcut ever
matches a given method on a target class. This evaluation can be performed when an AOP
proxy is created to avoid the need for a test on every method invocation. If the
two-argument `matches` method returns `true` for a given method, and the `isRuntime()`
method for the MethodMatcher returns `true`, the three-argument matches method is
invoked on every method invocation. This lets a pointcut look at the arguments passed
to the method invocation immediately before the target advice starts.
Most `MethodMatcher` implementations are static, meaning that their `isRuntime()` method
returns `false`. In this case, the three-argument `matches` method is never invoked.
TIP: If possible, try to make pointcuts static, allowing the AOP framework to cache the
results of pointcut evaluation when an AOP proxy is created.
[[aop-api-pointcut-ops]]
== Operations on Pointcuts
Spring supports operations (notably, union and intersection) on pointcuts.
Union means the methods that either pointcut matches.
Intersection means the methods that both pointcuts match.
Union is usually more useful.
You can compose pointcuts by using the static methods in the
`org.springframework.aop.support.Pointcuts` class or by using the
`ComposablePointcut` class in the same package. However, using AspectJ pointcut
expressions is usually a simpler approach.
[[aop-api-pointcuts-aspectj]]
== AspectJ Expression Pointcuts
Since 2.0, the most important type of pointcut used by Spring is
`org.springframework.aop.aspectj.AspectJExpressionPointcut`. This is a pointcut that
uses an AspectJ-supplied library to parse an AspectJ pointcut expression string.
See the xref:core/aop.adoc[previous chapter] for a discussion of supported AspectJ pointcut primitives.
[[aop-api-pointcuts-impls]]
== Convenience Pointcut Implementations
Spring provides several convenient pointcut implementations. You can use some of them
directly; others are intended to be subclassed in application-specific pointcuts.
[[aop-api-pointcuts-static]]
=== Static Pointcuts
Static pointcuts are based on the method and the target class and cannot take into account
the method's arguments. Static pointcuts suffice -- and are best -- for most usages.
Spring can evaluate a static pointcut only once, when a method is first invoked.
After that, there is no need to evaluate the pointcut again with each method invocation.
The rest of this section describes some of the static pointcut implementations that are
included with Spring.
[[aop-api-pointcuts-regex]]
==== Regular Expression Pointcuts
One obvious way to specify static pointcuts is regular expressions. Several AOP
frameworks besides Spring make this possible.
`org.springframework.aop.support.JdkRegexpMethodPointcut` is a generic regular
expression pointcut that uses the regular expression support in the JDK.
With the `JdkRegexpMethodPointcut` class, you can provide a list of pattern strings.
If any of these is a match, the pointcut evaluates to `true`. (As a consequence,
the resulting pointcut is effectively the union of the specified patterns.)
The following example shows how to use `JdkRegexpMethodPointcut`:
[source,xml,indent=0,subs="verbatim"]
----
<bean id="settersAndAbsquatulatePointcut"
class="org.springframework.aop.support.JdkRegexpMethodPointcut">
<property name="patterns">
<list>
<value>.*set.*</value>
<value>.*absquatulate</value>
</list>
</property>
</bean>
----
Spring provides a convenience class named `RegexpMethodPointcutAdvisor`, which lets us
also reference an `Advice` (remember that an `Advice` can be an interceptor, before advice,
throws advice, and others). Behind the scenes, Spring uses a `JdkRegexpMethodPointcut`.
Using `RegexpMethodPointcutAdvisor` simplifies wiring, as the one bean encapsulates both
pointcut and advice, as the following example shows:
[source,xml,indent=0,subs="verbatim"]
----
<bean id="settersAndAbsquatulateAdvisor"
class="org.springframework.aop.support.RegexpMethodPointcutAdvisor">
<property name="advice">
<ref bean="beanNameOfAopAllianceInterceptor"/>
</property>
<property name="patterns">
<list>
<value>.*set.*</value>
<value>.*absquatulate</value>
</list>
</property>
</bean>
----
You can use `RegexpMethodPointcutAdvisor` with any `Advice` type.
[[aop-api-pointcuts-attribute-driven]]
==== Attribute-driven Pointcuts
An important type of static pointcut is a metadata-driven pointcut. This uses the
values of metadata attributes (typically, source-level metadata).
[[aop-api-pointcuts-dynamic]]
=== Dynamic pointcuts
Dynamic pointcuts are costlier to evaluate than static pointcuts. They take into account
method arguments as well as static information. This means that they must be
evaluated with every method invocation and that the result cannot be cached, as arguments will
vary.
The main example is the `control flow` pointcut.
[[aop-api-pointcuts-cflow]]
==== Control Flow Pointcuts
Spring control flow pointcuts are conceptually similar to AspectJ `cflow` pointcuts,
although less powerful. (There is currently no way to specify that a pointcut runs
below a join point matched by another pointcut.) A control flow pointcut matches the
current call stack. For example, it might fire if the join point was invoked by a method
in the `com.mycompany.web` package or by the `SomeCaller` class. Control flow pointcuts
are specified by using the `org.springframework.aop.support.ControlFlowPointcut` class.
NOTE: Control flow pointcuts are significantly more expensive to evaluate at runtime than even
other dynamic pointcuts. In Java 1.4, the cost is about five times that of other dynamic
pointcuts.
[[aop-api-pointcuts-superclasses]]
== Pointcut Superclasses
Spring provides useful pointcut superclasses to help you to implement your own pointcuts.
Because static pointcuts are most useful, you should probably subclass
`StaticMethodMatcherPointcut`. This requires implementing only one
abstract method (although you can override other methods to customize behavior). The
following example shows how to subclass `StaticMethodMatcherPointcut`:
[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim,quotes",role="primary"]
----
class TestStaticPointcut extends StaticMethodMatcherPointcut {
public boolean matches(Method m, Class targetClass) {
// return true if custom criteria match
}
}
----
Kotlin::
+
[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
----
class TestStaticPointcut : StaticMethodMatcherPointcut() {
override fun matches(method: Method, targetClass: Class<*>): Boolean {
// return true if custom criteria match
}
}
----
======
There are also superclasses for dynamic pointcuts.
You can use custom pointcuts with any advice type.
[[aop-api-pointcuts-custom]]
== Custom Pointcuts
Because pointcuts in Spring AOP are Java classes rather than language features (as in
AspectJ), you can declare custom pointcuts, whether static or dynamic. Custom
pointcuts in Spring can be arbitrarily complex. However, we recommend using the AspectJ pointcut
expression language, if you can.
NOTE: Later versions of Spring may offer support for "`semantic pointcuts`" as offered by JAC --
for example, "`all methods that change instance variables in the target object.`"

[[aop-prog]]
= Creating AOP Proxies Programmatically with the `ProxyFactory`
It is easy to create AOP proxies programmatically with Spring. This lets you use
Spring AOP without dependency on Spring IoC.
The interfaces implemented by the target object are
automatically proxied. The following listing shows creation of a proxy for a target object, with one
interceptor and one advisor:
[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim,quotes",role="primary"]
----
ProxyFactory factory = new ProxyFactory(myBusinessInterfaceImpl);
factory.addAdvice(myMethodInterceptor);
factory.addAdvisor(myAdvisor);
MyBusinessInterface tb = (MyBusinessInterface) factory.getProxy();
----
Kotlin::
+
[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
----
val factory = ProxyFactory(myBusinessInterfaceImpl)
factory.addAdvice(myMethodInterceptor)
factory.addAdvisor(myAdvisor)
val tb = factory.proxy as MyBusinessInterface
----
======
The first step is to construct an object of type
`org.springframework.aop.framework.ProxyFactory`. You can create this with a target
object, as in the preceding example, or specify the interfaces to be proxied in an alternate
constructor.
You can add advice (with interceptors as a specialized kind of advice), advisors, or both
and manipulate them for the life of the `ProxyFactory`. If you add an
`IntroductionInterceptionAroundAdvisor`, you can cause the proxy to implement additional
interfaces.
There are also convenience methods on `ProxyFactory` (inherited from `AdvisedSupport`)
that let you add other advice types, such as before and throws advice.
`AdvisedSupport` is the superclass of both `ProxyFactory` and `ProxyFactoryBean`.
TIP: Integrating AOP proxy creation with the IoC framework is best practice in most
applications. We recommend that you externalize configuration from Java code with AOP,
as you should in general.
@@ -1,232 +0,0 @@
[[aop-targetsource]]
= Using `TargetSource` Implementations
Spring offers the concept of a `TargetSource`, expressed in the
`org.springframework.aop.TargetSource` interface. This interface is responsible for
returning the "`target object`" that implements the join point. The `TargetSource`
implementation is asked for a target instance each time the AOP proxy handles a method
invocation.
Developers who use Spring AOP do not normally need to work directly with `TargetSource` implementations, but
this provides a powerful means of supporting pooling, hot swappable, and other
sophisticated targets. For example, a pooling `TargetSource` can return a different target
instance for each invocation, by using a pool to manage instances.
If you do not specify a `TargetSource`, a default implementation is used to wrap a
local object. The same target is returned for each invocation (as you would expect).
The rest of this section describes the standard target sources provided with Spring and how you can use them.
TIP: When using a custom target source, your target will usually need to be a prototype
rather than a singleton bean definition. This allows Spring to create a new target
instance when required.
[[aop-ts-swap]]
== Hot-swappable Target Sources
The `org.springframework.aop.target.HotSwappableTargetSource` exists to let the target
of an AOP proxy be switched while letting callers keep their references to it.
Changing the target source's target takes effect immediately. The
`HotSwappableTargetSource` is thread-safe.
You can change the target by using the `swap()` method on HotSwappableTargetSource, as the follow example shows:
[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim,quotes",role="primary"]
----
HotSwappableTargetSource swapper = (HotSwappableTargetSource) beanFactory.getBean("swapper");
Object oldTarget = swapper.swap(newTarget);
----
Kotlin::
+
[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
----
val swapper = beanFactory.getBean("swapper") as HotSwappableTargetSource
val oldTarget = swapper.swap(newTarget)
----
======
The following example shows the required XML definitions:
[source,xml,indent=0,subs="verbatim,quotes"]
----
<bean id="initialTarget" class="mycompany.OldTarget"/>
<bean id="swapper" class="org.springframework.aop.target.HotSwappableTargetSource">
<constructor-arg ref="initialTarget"/>
</bean>
<bean id="swappable" class="org.springframework.aop.framework.ProxyFactoryBean">
<property name="targetSource" ref="swapper"/>
</bean>
----
The preceding `swap()` call changes the target of the swappable bean. Clients that hold a
reference to that bean are unaware of the change but immediately start hitting
the new target.
Although this example does not add any advice (it is not necessary to add advice to
use a `TargetSource`), any `TargetSource` can be used in conjunction with
arbitrary advice.
[[aop-ts-pool]]
== Pooling Target Sources
Using a pooling target source provides a similar programming model to stateless session
EJBs, in which a pool of identical instances is maintained, with method invocations
going to free objects in the pool.
A crucial difference between Spring pooling and SLSB pooling is that Spring pooling can
be applied to any POJO. As with Spring in general, this service can be applied in a
non-invasive way.
Spring provides support for Commons Pool 2.2, which provides a
fairly efficient pooling implementation. You need the `commons-pool` Jar on your
application's classpath to use this feature. You can also subclass
`org.springframework.aop.target.AbstractPoolingTargetSource` to support any other
pooling API.
NOTE: Commons Pool 1.5+ is also supported but is deprecated as of Spring Framework 4.2.
The following listing shows an example configuration:
[source,xml,indent=0,subs="verbatim,quotes"]
----
<bean id="businessObjectTarget" class="com.mycompany.MyBusinessObject"
scope="prototype">
... properties omitted
</bean>
<bean id="poolTargetSource" class="org.springframework.aop.target.CommonsPool2TargetSource">
<property name="targetBeanName" value="businessObjectTarget"/>
<property name="maxSize" value="25"/>
</bean>
<bean id="businessObject" class="org.springframework.aop.framework.ProxyFactoryBean">
<property name="targetSource" ref="poolTargetSource"/>
<property name="interceptorNames" value="myInterceptor"/>
</bean>
----
Note that the target object (`businessObjectTarget` in the preceding example) must be a
prototype. This lets the `PoolingTargetSource` implementation create new instances
of the target to grow the pool as necessary. See the {spring-framework-api}/aop/target/AbstractPoolingTargetSource.html[javadoc of
`AbstractPoolingTargetSource`] and the concrete subclass you wish to use for information
about its properties. `maxSize` is the most basic and is always guaranteed to be present.
In this case, `myInterceptor` is the name of an interceptor that would need to be
defined in the same IoC context. However, you need not specify interceptors to
use pooling. If you want only pooling and no other advice, do not set the
`interceptorNames` property at all.
You can configure Spring to be able to cast any pooled object to the
`org.springframework.aop.target.PoolingConfig` interface, which exposes information
about the configuration and current size of the pool through an introduction. You
need to define an advisor similar to the following:
[source,xml,indent=0,subs="verbatim,quotes"]
----
<bean id="poolConfigAdvisor" class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">
<property name="targetObject" ref="poolTargetSource"/>
<property name="targetMethod" value="getPoolingConfigMixin"/>
</bean>
----
This advisor is obtained by calling a convenience method on the
`AbstractPoolingTargetSource` class, hence the use of `MethodInvokingFactoryBean`. This
advisor's name (`poolConfigAdvisor`, here) must be in the list of interceptors names in
the `ProxyFactoryBean` that exposes the pooled object.
The cast is defined as follows:
[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim,quotes",role="primary"]
----
PoolingConfig conf = (PoolingConfig) beanFactory.getBean("businessObject");
System.out.println("Max pool size is " + conf.getMaxSize());
----
Kotlin::
+
[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
----
val conf = beanFactory.getBean("businessObject") as PoolingConfig
println("Max pool size is " + conf.maxSize)
----
======
NOTE: Pooling stateless service objects is not usually necessary. We do not believe it should
be the default choice, as most stateless objects are naturally thread-safe, and instance
pooling is problematic if resources are cached.
Simpler pooling is available by using auto-proxying. You can set the `TargetSource` implementations
used by any auto-proxy creator.
[[aop-ts-prototype]]
== Prototype Target Sources
Setting up a "`prototype`" target source is similar to setting up a pooling `TargetSource`. In this
case, a new instance of the target is created on every method invocation. Although
the cost of creating a new object is not high in a modern JVM, the cost of wiring up the
new object (satisfying its IoC dependencies) may be more expensive. Thus, you should not
use this approach without very good reason.
To do this, you could modify the `poolTargetSource` definition shown earlier as follows
(we also changed the name, for clarity):
[source,xml,indent=0,subs="verbatim,quotes"]
----
<bean id="prototypeTargetSource" class="org.springframework.aop.target.PrototypeTargetSource">
<property name="targetBeanName" ref="businessObjectTarget"/>
</bean>
----
The only property is the name of the target bean. Inheritance is used in the
`TargetSource` implementations to ensure consistent naming. As with the pooling target
source, the target bean must be a prototype bean definition.
[[aop-ts-threadlocal]]
== `ThreadLocal` Target Sources
`ThreadLocal` target sources are useful if you need an object to be created for each
incoming request (per thread that is). The concept of a `ThreadLocal` provides a JDK-wide
facility to transparently store a resource alongside a thread. Setting up a
`ThreadLocalTargetSource` is pretty much the same as was explained for the other types
of target source, as the following example shows:
[source,xml,indent=0,subs="verbatim,quotes"]
----
<bean id="threadlocalTargetSource" class="org.springframework.aop.target.ThreadLocalTargetSource">
<property name="targetBeanName" value="businessObjectTarget"/>
</bean>
----
NOTE: `ThreadLocal` instances come with serious issues (potentially resulting in memory leaks) when
incorrectly using them in multi-threaded and multi-classloader environments. You
should always consider wrapping a `ThreadLocal` in some other class and never directly use
the `ThreadLocal` itself (except in the wrapper class). Also, you should
always remember to correctly set and unset (where the latter involves a call to
`ThreadLocal.remove()`) the resource local to the thread. Unsetting should be done in
any case, since not unsetting it might result in problematic behavior. Spring's
`ThreadLocal` support does this for you and should always be considered in favor of using
`ThreadLocal` instances without other proper handling code.

= Aspect Oriented Programming with Spring
Aspect-oriented Programming (AOP) complements Object-oriented Programming (OOP) by
providing another way of thinking about program structure. The key unit of modularity
in OOP is the class, whereas in AOP the unit of modularity is the aspect. Aspects
enable the modularization of concerns (such as transaction management) that cut across
multiple types and objects. (Such concerns are often termed "crosscutting" concerns
in AOP literature.)
One of the key components of Spring is the AOP framework. While the Spring IoC
container does not depend on AOP (meaning you do not need to use AOP if you don't want
to), AOP complements Spring IoC to provide a very capable middleware solution.

[[aop-advice-after-returning]]
== After Returning Advice
After returning advice runs when a matched method execution returns normally.
You can declare it by using the `@AfterReturning` annotation.
[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim",role="primary"]
----
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.AfterReturning;
@Aspect
public class AfterReturningExample {
@AfterReturning("execution(* com.xyz.dao.*.*(..))")
public void doAccessCheck() {
// ...
}
}
----
Kotlin::
+
[source,kotlin,indent=0,subs="verbatim",role="secondary"]
----
import org.aspectj.lang.annotation.Aspect
import org.aspectj.lang.annotation.AfterReturning
@Aspect
class AfterReturningExample {
@AfterReturning("execution(* com.xyz.dao.*.*(..))")
fun doAccessCheck() {
// ...
}
}
----
======
NOTE: You can have multiple advice declarations (and other members as well),
all inside the same aspect. We show only a single advice declaration in these
examples to focus the effect of each one.
Sometimes, you need access in the advice body to the actual value that was returned.
You can use the form of `@AfterReturning` that binds the return value to get that
access, as the following example shows:
[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim",role="primary"]
----
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.AfterReturning;
@Aspect
public class AfterReturningExample {
@AfterReturning(
pointcut="execution(* com.xyz.dao.*.*(..))",
returning="retVal")
public void doAccessCheck(Object retVal) {
// ...
}
}
----
Kotlin::
+
[source,kotlin,indent=0,subs="verbatim",role="secondary"]
----
import org.aspectj.lang.annotation.Aspect
import org.aspectj.lang.annotation.AfterReturning
@Aspect
class AfterReturningExample {
@AfterReturning(
pointcut = "execution(* com.xyz.dao.*.*(..))",
returning = "retVal")
fun doAccessCheck(retVal: Any?) {
// ...
}
}
----
======
The name used in the `returning` attribute must correspond to the name of a parameter
in the advice method. When a method execution returns, the return value is passed to
the advice method as the corresponding argument value. A `returning` clause also
restricts matching to only those method executions that return a value of the
specified type (in this case, `Object`, which matches any return value).
Please note that it is not possible to return a totally different reference when
using after returning advice.
[[aop-advice-after-throwing]]
== After Throwing Advice
After throwing advice runs when a matched method execution exits by throwing an
exception. You can declare it by using the `@AfterThrowing` annotation, as the
following example shows:
[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim",role="primary"]
----
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.AfterThrowing;
@Aspect
public class AfterThrowingExample {
@AfterThrowing("execution(* com.xyz.dao.*.*(..))")
public void doRecoveryActions() {
// ...
}
}
----
Kotlin::
+
[source,kotlin,indent=0,subs="verbatim",role="secondary"]
----
import org.aspectj.lang.annotation.Aspect
import org.aspectj.lang.annotation.AfterThrowing
@Aspect
class AfterThrowingExample {
@AfterThrowing("execution(* com.xyz.dao.*.*(..))")
fun doRecoveryActions() {
// ...
}
}
----
======
Often, you want the advice to run only when exceptions of a given type are thrown,
and you also often need access to the thrown exception in the advice body. You can
use the `throwing` attribute to both restrict matching (if desired -- use `Throwable`
as the exception type otherwise) and bind the thrown exception to an advice parameter.
The following example shows how to do so:
[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim",role="primary"]
----
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.AfterThrowing;
@Aspect
public class AfterThrowingExample {
@AfterThrowing(
pointcut="execution(* com.xyz.dao.*.*(..))",
throwing="ex")
public void doRecoveryActions(DataAccessException ex) {
// ...
}
}
----
Kotlin::
+
[source,kotlin,indent=0,subs="verbatim",role="secondary"]
----
import org.aspectj.lang.annotation.Aspect
import org.aspectj.lang.annotation.AfterThrowing
@Aspect
class AfterThrowingExample {
@AfterThrowing(
pointcut = "execution(* com.xyz.dao.*.*(..))",
throwing = "ex")
fun doRecoveryActions(ex: DataAccessException) {
// ...
}
}
----
======
The name used in the `throwing` attribute must correspond to the name of a parameter in
the advice method. When a method execution exits by throwing an exception, the exception
is passed to the advice method as the corresponding argument value. A `throwing` clause
also restricts matching to only those method executions that throw an exception of the
specified type (`DataAccessException`, in this case).
[NOTE]
====
Note that `@AfterThrowing` does not indicate a general exception handling callback.
Specifically, an `@AfterThrowing` advice method is only supposed to receive exceptions
from the join point (user-declared target method) itself but not from an accompanying
`@After`/`@AfterReturning` method.
====
[[aop-advice-after-finally]]
== After (Finally) Advice
After (finally) advice runs when a matched method execution exits. It is declared by
using the `@After` annotation. After advice must be prepared to handle both normal and
exception return conditions. It is typically used for releasing resources and similar
purposes. The following example shows how to use after finally advice:
[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim",role="primary"]
----
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.After;
@Aspect
public class AfterFinallyExample {
@After("execution(* com.xyz.dao.*.*(..))")
public void doReleaseLock() {
// ...
}
}
----
Kotlin::
+
[source,kotlin,indent=0,subs="verbatim",role="secondary"]
----
import org.aspectj.lang.annotation.Aspect
import org.aspectj.lang.annotation.After
@Aspect
class AfterFinallyExample {
@After("execution(* com.xyz.dao.*.*(..))")
fun doReleaseLock() {
// ...
}
}
----
======
[NOTE]
====
Note that `@After` advice in AspectJ is defined as "after finally advice", analogous
to a finally block in a try-catch statement. It will be invoked for any outcome,
normal return or exception thrown from the join point (user-declared target method),
in contrast to `@AfterReturning` which only applies to successful normal returns.
====
[[aop-ataspectj-around-advice]]
== Around Advice
The last kind of advice is _around_ advice. Around advice runs "around" a matched
method's execution. It has the opportunity to do work both before and after the method
runs and to determine when, how, and even if the method actually gets to run at all.
Around advice is often used if you need to share state before and after a method
execution in a thread-safe manner for example, starting and stopping a timer.
[TIP]
====
Always use the least powerful form of advice that meets your requirements.
For example, do not use _around_ advice if _before_ advice is sufficient for your needs.
====
Around advice is declared by annotating a method with the `@Around` annotation. The
method should declare `Object` as its return type, and the first parameter of the method
must be of type `ProceedingJoinPoint`. Within the body of the advice method, you must
invoke `proceed()` on the `ProceedingJoinPoint` in order for the underlying method to
run. Invoking `proceed()` without arguments will result in the caller's original
arguments being supplied to the underlying method when it is invoked. For advanced use
cases, there is an overloaded variant of the `proceed()` method which accepts an array of
arguments (`Object[]`). The values in the array will be used as the arguments to the
underlying method when it is invoked.
[NOTE]
====
The behavior of `proceed` when called with an `Object[]` is a little different than the
behavior of `proceed` for around advice compiled by the AspectJ compiler. For around
advice written using the traditional AspectJ language, the number of arguments passed to
`proceed` must match the number of arguments passed to the around advice (not the number
of arguments taken by the underlying join point), and the value passed to proceed in a
given argument position supplants the original value at the join point for the entity the
value was bound to (do not worry if this does not make sense right now).
The approach taken by Spring is simpler and a better match to its proxy-based,
execution-only semantics. You only need to be aware of this difference if you compile
`@AspectJ` aspects written for Spring and use `proceed` with arguments with the AspectJ
compiler and weaver. There is a way to write such aspects that is 100% compatible across
both Spring AOP and AspectJ, and this is discussed in the
xref:core/aop/ataspectj/advice.adoc#aop-ataspectj-advice-proceeding-with-the-call[following section on advice parameters].
====
The value returned by the around advice is the return value seen by the caller of the
method. For example, a simple caching aspect could return a value from a cache if it has
one or invoke `proceed()` (and return that value) if it does not. Note that `proceed`
may be invoked once, many times, or not at all within the body of the around advice. All
of these are legal.
WARNING: If you declare the return type of your around advice method as `void`, `null`
will always be returned to the caller, effectively ignoring the result of any invocation
of `proceed()`. It is therefore recommended that an around advice method declare a return
type of `Object`. The advice method should typically return the value returned from an
invocation of `proceed()`, even if the underlying method has a `void` return type.
However, the advice may optionally return a cached value, a wrapped value, or some other
value depending on the use case.
The following example shows how to use around advice:

----
======
[[aop-ataspectj-advice-params]]
== Advice Parameters
Spring offers fully typed advice, meaning that you declare the parameters you need in the
advice signature (as we saw earlier for the returning and throwing examples) rather than
work with `Object[]` arrays all the time. We see how to make argument and other contextual
values available to the advice body later in this section. First, we take a look at how to
write generic advice that can find out about the method the advice is currently advising.
[[aop-ataspectj-advice-params-the-joinpoint]]
=== Access to the Current `JoinPoint`
Any advice method may declare, as its first parameter, a parameter of type
`org.aspectj.lang.JoinPoint`. Note that around advice is required to declare a first
parameter of type `ProceedingJoinPoint`, which is a subclass of `JoinPoint`.
The `JoinPoint` interface provides a number of useful methods:
* `getArgs()`: Returns the method arguments.
* `getThis()`: Returns the proxy object.
* `getTarget()`: Returns the target object.
* `getSignature()`: Returns a description of the method that is being advised.
* `toString()`: Prints a useful description of the method being advised.
See the {aspectj-api}/org/aspectj/lang/JoinPoint.html[javadoc] for more detail.
[[aop-ataspectj-advice-params-passing]]
=== Passing Parameters to Advice
We have already seen how to bind the returned value or exception value (using after
returning and after throwing advice). To make argument values available to the advice
body, you can use the binding form of `args`. If you use a parameter name in place of a
type name in an `args` expression, the value of the corresponding argument is passed as
the parameter value when the advice is invoked. An example should make this clearer.
Suppose you want to advise the execution of DAO operations that take an `Account`
object as the first parameter, and you need access to the account in the advice body.
You could write the following:
[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim",role="primary"]
----
@Before("execution(* com.xyz.dao.*.*(..)) && args(account,..)")
public void validateAccount(Account account) {
// ...
}
----
Kotlin::
+
[source,kotlin,indent=0,subs="verbatim",role="secondary"]
----
@Before("execution(* com.xyz.dao.*.*(..)) && args(account,..)")
fun validateAccount(account: Account) {
// ...
}
----
======
The `args(account,..)` part of the pointcut expression serves two purposes. First, it
restricts matching to only those method executions where the method takes at least one
parameter, and the argument passed to that parameter is an instance of `Account`.
Second, it makes the actual `Account` object available to the advice through the `account`
parameter.
Another way of writing this is to declare a pointcut that "provides" the `Account`
object value when it matches a join point, and then refer to the named pointcut
from the advice. This would look as follows:
[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim",role="primary"]
----
@Pointcut("execution(* com.xyz.dao.*.*(..)) && args(account,..)")
private void accountDataAccessOperation(Account account) {}
@Before("accountDataAccessOperation(account)")
public void validateAccount(Account account) {
// ...
}
----
Kotlin::
+
[source,kotlin,indent=0,subs="verbatim",role="secondary"]
----
@Pointcut("execution(* com.xyz.dao.*.*(..)) && args(account,..)")
private fun accountDataAccessOperation(account: Account) {
}
@Before("accountDataAccessOperation(account)")
fun validateAccount(account: Account) {
// ...
}
----
======
See the AspectJ programming guide for more details.
The proxy object (`this`), target object (`target`), and annotations (`@within`,
`@target`, `@annotation`, and `@args`) can all be bound in a similar fashion. The next
set of examples shows how to match the execution of methods annotated with an
`@Auditable` annotation and extract the audit code:
The following shows the definition of the `@Auditable` annotation:
[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim",role="primary"]

[[aop-ataspectj-advice-params-generics]]
=== Advice Parameters and Generics
Spring AOP can handle generics used in class declarations and method parameters. Suppose
you have a generic type like the following:
[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim",role="primary"]
----
public interface Sample<T> {
void sampleGenericMethod(T param);
void sampleGenericCollectionMethod(Collection<T> param);
}
----
Kotlin::
+
[source,kotlin,indent=0,subs="verbatim",role="secondary"]
----
interface Sample<T> {
fun sampleGenericMethod(param: T)
fun sampleGenericCollectionMethod(param: Collection<T>)
}
----
======
You can restrict interception of method types to certain parameter types by
tying the advice parameter to the parameter type for which you want to intercept the method:
[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim",role="primary"]
----
@Before("execution(* ..Sample+.sampleGenericMethod(*)) && args(param)")
public void beforeSampleMethod(MyType param) {
// Advice implementation
}
----
Kotlin::
+
[source,kotlin,indent=0,subs="verbatim",role="secondary"]
----
@Before("execution(* ..Sample+.sampleGenericMethod(*)) && args(param)")
fun beforeSampleMethod(param: MyType) {
// Advice implementation
}
----
======
This approach does not work for generic collections. So you cannot define a
pointcut as follows:
[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim",role="primary"]
----
@Before("execution(* ..Sample+.sampleGenericCollectionMethod(*)) && args(param)")
public void beforeSampleMethod(Collection<MyType> param) {
// Advice implementation
}
----
Kotlin::
+
[source,kotlin,indent=0,subs="verbatim",role="secondary"]
----
@Before("execution(* ..Sample+.sampleGenericCollectionMethod(*)) && args(param)")
fun beforeSampleMethod(param: Collection<MyType>) {
// Advice implementation
}
----
======
To make this work, we would have to inspect every element of the collection, which is not
reasonable, as we also cannot decide how to treat `null` values in general. To achieve
something similar to this, you have to type the parameter to `Collection<?>` and manually
check the type of the elements.
[[aop-ataspectj-advice-params-names]]
=== Determining Argument Names
Parameter binding in advice invocations relies on matching the names used in pointcut
expressions to the parameter names declared in advice and pointcut method signatures.
NOTE: This section uses the terms _argument_ and _parameter_ interchangeably, since
AspectJ APIs refer to parameter names as argument names.
Spring AOP uses the following `ParameterNameDiscoverer` implementations to determine
parameter names. Each discoverer will be given a chance to discover parameter names, and
the first successful discoverer wins. If none of the registered discoverers is capable
of determining parameter names, an exception will be thrown.
`AspectJAnnotationParameterNameDiscoverer` :: Uses parameter names that have been explicitly
specified by the user via the `argNames` attribute in the corresponding advice or
pointcut annotation. See xref:core/aop/ataspectj/advice.adoc#aop-ataspectj-advice-params-names-explicit[Explicit Argument Names] for details.
`KotlinReflectionParameterNameDiscoverer` :: Uses Kotlin reflection APIs to determine
parameter names. This discoverer is only used if such APIs are present on the classpath.
`StandardReflectionParameterNameDiscoverer` :: Uses the standard `java.lang.reflect.Parameter`
API to determine parameter names. Requires that code be compiled with the `-parameters`
flag for `javac`. Recommended approach on Java 8+.
`AspectJAdviceParameterNameDiscoverer` :: Deduces parameter names from the pointcut
expression, `returning`, and `throwing` clauses. See the
{spring-framework-api}/aop/aspectj/AspectJAdviceParameterNameDiscoverer.html[javadoc]
for details on the algorithm used.
[[aop-ataspectj-advice-params-names-explicit]]
=== Explicit Argument Names
@AspectJ advice and pointcut annotations have an optional `argNames` attribute that you
can use to specify the argument names of the annotated method.
[TIP]
====
If an @AspectJ aspect has been compiled by the AspectJ compiler (`ajc`) even without
debug information, you do not need to add the `argNames` attribute, since the compiler
retains the needed information.
Similarly, if an @AspectJ aspect has been compiled with `javac` using the `-parameters`
flag, you do not need to add the `argNames` attribute, since the compiler retains the
needed information.
====
The following example shows how to use the `argNames` attribute:
[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim",role="primary"]

AuditCode code = auditable.value();
// ... use code and bean
}
----
<1> References the `publicMethod` named pointcut defined in xref:core/aop/ataspectj/pointcuts.adoc#aop-pointcuts-combining[Combining Pointcut Expressions].
<2> Declares `bean` and `auditable` as the argument names.
Kotlin::

[source,kotlin,indent=0,subs="verbatim",role="secondary"]
----
@Before(
value = "com.xyz.Pointcuts.publicMethod() && target(bean) && @annotation(auditable)", // <1>
argNames = "bean,auditable") // <2>
fun audit(bean: Any, auditable: Auditable) {
val code = auditable.value()
// ... use code and bean
}
----
<1> References the `publicMethod` named pointcut defined in xref:core/aop/ataspectj/pointcuts.adoc#aop-pointcuts-combining[Combining Pointcut Expressions].
<2> Declares `bean` and `auditable` as the argument names.
======
If the first parameter is of type `JoinPoint`, `ProceedingJoinPoint`, or
`JoinPoint.StaticPart`, you can omit the name of the parameter from the value of the
`argNames` attribute. For example, if you modify the preceding advice to receive the join
point object, the `argNames` attribute does not need to include it:
[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim",role="primary"]
----
@Before(
value = "com.xyz.Pointcuts.publicMethod() && target(bean) && @annotation(auditable)", // <1>
argNames = "bean,auditable") // <2>

AuditCode code = auditable.value();
// ... use code, bean, and jp
}
----
<1> References the `publicMethod` named pointcut defined in xref:core/aop/ataspectj/pointcuts.adoc#aop-pointcuts-combining[Combining Pointcut Expressions].
<2> Declares `bean` and `auditable` as the argument names.

@Before(
value = "com.xyz.Pointcuts.publicMethod() && target(bean) && @annotation(auditable)", // <1>
argNames = "bean,auditable") // <2>
fun audit(jp: JoinPoint, bean: Any, auditable: Auditable) {
val code = auditable.value()
// ... use code, bean, and jp
}
----
<1> References the `publicMethod` named pointcut defined in xref:core/aop/ataspectj/pointcuts.adoc#aop-pointcuts-combining[Combining Pointcut Expressions].
<2> Declares `bean` and `auditable` as the argument names.
======
The special treatment given to the first parameter of type `JoinPoint`,
`ProceedingJoinPoint`, or `JoinPoint.StaticPart` is particularly convenient for advice
methods that do not collect any other join point context. In such situations, you may
omit the `argNames` attribute. For example, the following advice does not need to declare
the `argNames` attribute:
[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim",role="primary"]

======
[[aop-ataspectj-advice-proceeding-with-the-call]]
=== Proceeding with Arguments
We remarked earlier that we would describe how to write a `proceed` call with
arguments that works consistently across Spring AOP and AspectJ. The solution is
to ensure that the advice signature binds each of the method parameters in order.
The following example shows how to do so:
[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim",role="primary"]
----
@Around("execution(List<Account> find*(..)) && " +
"com.xyz.CommonPointcuts.inDataAccessLayer() && " +
"args(accountHolderNamePattern)") // <1>
public Object preProcessQueryPattern(ProceedingJoinPoint pjp,
String accountHolderNamePattern) throws Throwable {
String newPattern = preProcess(accountHolderNamePattern);
return pjp.proceed(new Object[] {newPattern});
}
----
<1> References the `inDataAccessLayer` named pointcut defined in xref:core/aop/ataspectj/pointcuts.adoc#aop-common-pointcuts[Sharing Named Pointcut Definitions].
Kotlin::
+
[source,kotlin,indent=0,subs="verbatim",role="secondary"]
----
@Around("execution(List<Account> find*(..)) && " +
"com.xyz.CommonPointcuts.inDataAccessLayer() && " +
"args(accountHolderNamePattern)") // <1>
fun preProcessQueryPattern(pjp: ProceedingJoinPoint,
accountHolderNamePattern: String): Any? {
val newPattern = preProcess(accountHolderNamePattern)
return pjp.proceed(arrayOf<Any>(newPattern))
}
----
<1> References the `inDataAccessLayer` named pointcut defined in xref:core/aop/ataspectj/pointcuts.adoc#aop-common-pointcuts[Sharing Named Pointcut Definitions].
======
In many cases, you do this binding anyway (as in the preceding example).
[[aop-ataspectj-advice-ordering]]
== Advice Ordering
What happens when multiple pieces of advice all want to run at the same join point?
Spring AOP follows the same precedence rules as AspectJ to determine the order of advice
execution. The highest precedence advice runs first "on the way in" (so, given two pieces
of before advice, the one with highest precedence runs first). "On the way out" from a
join point, the highest precedence advice runs last (so, given two pieces of after
advice, the one with the highest precedence will run second).
When two pieces of advice defined in different aspects both need to run at the same
join point, unless you specify otherwise, the order of execution is undefined. You can
control the order of execution by specifying precedence. This is done in the normal
Spring way by either implementing the `org.springframework.core.Ordered` interface in
the aspect class or annotating it with the `@Order` annotation. Given two aspects, the
aspect returning the lower value from `Ordered.getOrder()` (or the annotation value) has
the higher precedence.
[NOTE]
====
Each of the distinct advice types of a particular aspect is conceptually meant to apply
to the join point directly. As a consequence, an `@AfterThrowing` advice method is not
supposed to receive an exception from an accompanying `@After`/`@AfterReturning` method.
As of Spring Framework 5.2.7, advice methods defined in the same `@Aspect` class that
need to run at the same join point are assigned precedence based on their advice type in
the following order, from highest to lowest precedence: `@Around`, `@Before`, `@After`,
`@AfterReturning`, `@AfterThrowing`. Note, however, that an `@After` advice method will
effectively be invoked after any `@AfterReturning` or `@AfterThrowing` advice methods
in the same aspect, following AspectJ's "after finally advice" semantics for `@After`.
When two pieces of the same type of advice (for example, two `@After` advice methods)
defined in the same `@Aspect` class both need to run at the same join point, the ordering
is undefined (since there is no way to retrieve the source code declaration order through
reflection for javac-compiled classes). Consider collapsing such advice methods into one
advice method per join point in each `@Aspect` class or refactor the pieces of advice into
separate `@Aspect` classes that you can order at the aspect level via `Ordered` or `@Order`.

[[aop-aspectj-support]]
= Enabling @AspectJ Support
To use @AspectJ aspects in a Spring configuration, you need to enable Spring support for
configuring Spring AOP based on @AspectJ aspects and auto-proxying beans based on
whether or not they are advised by those aspects. By auto-proxying, we mean that, if Spring
determines that a bean is advised by one or more aspects, it automatically generates
a proxy for that bean to intercept method invocations and ensures that advice is run
as needed.
The @AspectJ support can be enabled with XML- or Java-style configuration. In either
case, you also need to ensure that AspectJ's `aspectjweaver.jar` library is on the
classpath of your application (version 1.9 or later). This library is available in the
`lib` directory of an AspectJ distribution or from the Maven Central repository.

= Declaring an Aspect
With @AspectJ support enabled, any bean defined in your application context with a
class that is an @AspectJ aspect (has the `@Aspect` annotation) is automatically
detected by Spring and used to configure Spring AOP. The next two examples show the
minimal steps required for a not-very-useful aspect.
The first of the two examples shows a regular bean definition in the application context
that points to a bean class that is annotated with `@Aspect`:
[source,xml,indent=0,subs="verbatim"]
----
<bean id="myAspect" class="com.xyz.NotVeryUsefulAspect">
<!-- configure properties of the aspect here -->

Aspects (classes annotated with `@Aspect`) can have methods and fields, the same as any
other class. They can also contain pointcut, advice, and introduction (inter-type)
declarations.
.Autodetecting aspects through component scanning
NOTE: You can register aspect classes as regular beans in your Spring XML configuration,
via `@Bean` methods in `@Configuration` classes, or have Spring autodetect them through
classpath scanning -- the same as any other Spring-managed bean. However, note that the
`@Aspect` annotation is not sufficient for autodetection in the classpath. For that
purpose, you need to add a separate `@Component` annotation (or, alternatively, a custom
stereotype annotation that qualifies, as per the rules of Spring's component scanner).
.Advising aspects with other aspects?
NOTE: In Spring AOP, aspects themselves cannot be the targets of advice from other
aspects. The `@Aspect` annotation on a class marks it as an aspect and, hence, excludes
it from auto-proxying.

[[aop-ataspectj-example]]
= An AOP Example
Now that you have seen how all the constituent parts work, we can put them together to do
something useful.
The execution of business services can sometimes fail due to concurrency issues (for
example, a deadlock loser). If the operation is retried, it is likely to succeed
on the next try. For business services where it is appropriate to retry in such
conditions (idempotent operations that do not need to go back to the user for conflict
resolution), we want to transparently retry the operation to avoid the client seeing a
`PessimisticLockingFailureException`. This is a requirement that clearly cuts across
multiple services in the service layer and, hence, is ideal for implementing through an
aspect.
Because we want to retry the operation, we need to use around advice so that we can
call `proceed` multiple times. The following listing shows the basic aspect implementation:
[tabs]

======
Note that the aspect implements the `Ordered` interface so that we can set the precedence of
the aspect higher than the transaction advice (we want a fresh transaction each time we
retry). The `maxRetries` and `order` properties are both configured by Spring. The
main action happens in the `doConcurrentOperation` around advice. Notice that, for the
moment, we apply the retry logic to each `businessService`. We try to proceed,
and if we fail with a `PessimisticLockingFailureException`, we try again, unless
we have exhausted all of our retry attempts.
The corresponding Spring configuration follows:
[source,xml,indent=0,subs="verbatim"]
----
<aop:aspectj-autoproxy/>
<bean id="concurrentOperationExecutor"
class="com.xyz.service.impl.ConcurrentOperationExecutor">
<property name="maxRetries" value="3"/>

</bean>
----
To refine the aspect so that it retries only idempotent operations, we might define the following
`Idempotent` annotation:
[tabs]
======
Java::

We can then use the annotation to annotate the implementation of service operations. The change
to the aspect to retry only idempotent operations involves refining the pointcut
expression so that only `@Idempotent` operations match, as follows:

[[aop-instantiation-models]]
= Aspect Instantiation Models
NOTE: This is an advanced topic. If you are just starting out with AOP, you can safely skip
it until later.
By default, there is a single instance of each aspect within the application
context. AspectJ calls this the singleton instantiation model. It is possible to define
aspects with alternate lifecycles. Spring supports AspectJ's `perthis`, `pertarget`, and
`pertypewithin` instantiation models; `percflow` and `percflowbelow` are not currently
supported.
You can declare a `perthis` aspect by specifying a `perthis` clause in the `@Aspect`
annotation. Consider the following example:
[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim",role="primary"]
----
@Aspect("perthis(execution(* com.xyz..service.*.*(..)))")
public class MyAspect {
private int someState;
@Before("execution(* com.xyz..service.*.*(..))")
public void recordServiceUsage() {
// ...
}
}
----
Kotlin::
+
[source,kotlin,indent=0,subs="verbatim",role="secondary"]
----
@Aspect("perthis(execution(* com.xyz..service.*.*(..)))")
class MyAspect {
private val someState: Int = 0
@Before("execution(* com.xyz..service.*.*(..))")
fun recordServiceUsage() {
// ...
}
}
----
======
In the preceding example, the effect of the `perthis` clause is that one aspect instance
is created for each unique service object that performs a business service (each unique
object bound to `this` at join points matched by the pointcut expression). The aspect
instance is created the first time that a method is invoked on the service object. The
aspect goes out of scope when the service object goes out of scope. Before the aspect
instance is created, none of the advice within it runs. As soon as the aspect instance
has been created, the advice declared within it runs at matched join points, but only
when the service object is the one with which this aspect is associated. See the AspectJ
Programming Guide for more information on `per` clauses.
The `pertarget` instantiation model works in exactly the same way as `perthis`, but it
creates one aspect instance for each unique target object at matched join points.

[[aop-introductions]]
= Introductions
Introductions (known as inter-type declarations in AspectJ) enable an aspect to declare
that advised objects implement a given interface, and to provide an implementation of
that interface on behalf of those objects.
You can make an introduction by using the `@DeclareParents` annotation. This annotation
is used to declare that matching types have a new parent (hence the name). For example,
given an interface named `UsageTracked` and an implementation of that interface named
`DefaultUsageTracked`, the following aspect declares that all implementors of service
interfaces also implement the `UsageTracked` interface (e.g. for statistics via JMX):
[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim",role="primary"]
----
@Aspect
public class UsageTracking {
@DeclareParents(value="com.xyz.service.*+", defaultImpl=DefaultUsageTracked.class)
public static UsageTracked mixin;
@Before("execution(* com.xyz..service.*.*(..)) && this(usageTracked)")
public void recordUsage(UsageTracked usageTracked) {
usageTracked.incrementUseCount();

}
@Before("execution(* com.xyz..service.*.*(..)) && this(usageTracked)")
fun recordUsage(usageTracked: UsageTracked) {
usageTracked.incrementUseCount()
}
}
----
======
The interface to be implemented is determined by the type of the annotated field. The
`value` attribute of the `@DeclareParents` annotation is an AspectJ type pattern. Any
bean of a matching type implements the `UsageTracked` interface. Note that, in the
before advice of the preceding example, service beans can be directly used as
implementations of the `UsageTracked` interface. If accessing a bean programmatically,
you would write the following:

[[aop-pointcuts]]
= Declaring a Pointcut
Pointcuts determine join points of interest and thus enable us to control
when advice runs. Spring AOP only supports method execution join points for Spring
beans, so you can think of a pointcut as matching the execution of methods on Spring
beans. A pointcut declaration has two parts: a signature comprising a name and any
parameters and a pointcut expression that determines exactly which method
executions we are interested in. In the @AspectJ annotation-style of AOP, a pointcut
signature is provided by a regular method definition, and the pointcut expression is
indicated by using the `@Pointcut` annotation (the method serving as the pointcut signature
must have a `void` return type).
An example may help make this distinction between a pointcut signature and a pointcut
expression clear. The following example defines a pointcut named `anyOldTransfer` that
matches the execution of any method named `transfer`:
[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim",role="primary"]
----
@Pointcut("execution(* transfer(..))") // the pointcut expression
private void anyOldTransfer() {} // the pointcut signature
----
Kotlin::
+
[source,kotlin,indent=0,subs="verbatim",role="secondary"]
----
@Pointcut("execution(* transfer(..))") // the pointcut expression
private fun anyOldTransfer() {} // the pointcut signature
----
======
The pointcut expression that forms the value of the `@Pointcut` annotation is a regular
AspectJ pointcut expression. For a full discussion of AspectJ's pointcut language, see
the {aspectj-docs-progguide}/index.html[AspectJ
Programming Guide] (and, for extensions, the
{aspectj-docs}/adk15notebook/index.html[AspectJ 5
Developer's Notebook]) or one of the books on AspectJ (such as _Eclipse AspectJ_, by Colyer
et al., or _AspectJ in Action_, by Ramnivas Laddad).
[[aop-pointcuts-designators]]
== Supported Pointcut Designators
Spring AOP supports the following AspectJ pointcut designators (PCD) for use in pointcut
expressions:
* `execution`: For matching method execution join points. This is the primary
pointcut designator to use when working with Spring AOP.
* `within`: Limits matching to join points within certain types (the execution
of a method declared within a matching type when using Spring AOP).
* `this`: Limits matching to join points (the execution of methods when using Spring
AOP) where the bean reference (Spring AOP proxy) is an instance of the given type.
* `target`: Limits matching to join points (the execution of methods when using
Spring AOP) where the target object (application object being proxied) is an instance
of the given type.
* `args`: Limits matching to join points (the execution of methods when using Spring
AOP) where the arguments are instances of the given types.
* `@target`: Limits matching to join points (the execution of methods when using
Spring AOP) where the class of the executing object has an annotation of the given type.
* `@args`: Limits matching to join points (the execution of methods when using Spring
AOP) where the runtime type of the actual arguments passed have annotations of the
given types.
* `@within`: Limits matching to join points within types that have the given
annotation (the execution of methods declared in types with the given annotation when
using Spring AOP).
* `@annotation`: Limits matching to join points where the subject of the join point
(the method being run in Spring AOP) has the given annotation.
.Other pointcut types
****
The full AspectJ pointcut language supports additional pointcut designators that are not
supported in Spring: `call`, `get`, `set`, `preinitialization`,
`staticinitialization`, `initialization`, `handler`, `adviceexecution`, `withincode`, `cflow`,
`cflowbelow`, `if`, `@this`, and `@withincode`. Use of these pointcut designators in pointcut
expressions interpreted by Spring AOP results in an `IllegalArgumentException` being
thrown.
The set of pointcut designators supported by Spring AOP may be extended in future
releases to support more of the AspectJ pointcut designators.
****
Because Spring AOP limits matching to only method execution join points, the preceding discussion
of the pointcut designators gives a narrower definition than you can find in the
AspectJ programming guide. In addition, AspectJ itself has type-based semantics and, at
an execution join point, both `this` and `target` refer to the same object: the
object executing the method. Spring AOP is a proxy-based system and differentiates
between the proxy object itself (which is bound to `this`) and the target object behind the
proxy (which is bound to `target`).
[NOTE]
====
Due to the proxy-based nature of Spring's AOP framework, calls within the target object
are, by definition, not intercepted. For JDK proxies, only public interface method
calls on the proxy can be intercepted. With CGLIB, public and protected method calls on
the proxy are intercepted (and even package-visible methods, if necessary). However,
common interactions through proxies should always be designed through public signatures.
Note that pointcut definitions are generally matched against any intercepted method.
If a pointcut is strictly meant to be public-only, even in a CGLIB proxy scenario with
potential non-public interactions through proxies, it needs to be defined accordingly.
If your interception needs include method calls or even constructors within the target
class, consider the use of Spring-driven xref:core/aop/using-aspectj.adoc#aop-aj-ltw[native AspectJ weaving] instead
of Spring's proxy-based AOP framework. This constitutes a different mode of AOP usage
with different characteristics, so be sure to make yourself familiar with weaving
before making a decision.
====
Spring AOP also supports an additional PCD named `bean`. This PCD lets you limit
the matching of join points to a particular named Spring bean or to a set of named
Spring beans (when using wildcards). The `bean` PCD has the following form:
[source,indent=0,subs="verbatim"]
----
bean(idOrNameOfBean)
----
The `idOrNameOfBean` token can be the name of any Spring bean. Limited wildcard
support that uses the `*` character is provided, so, if you establish some naming
conventions for your Spring beans, you can write a `bean` PCD expression
to select them. As is the case with other pointcut designators, the `bean` PCD can
be used with the `&&` (and), `||` (or), and `!` (negation) operators, too.
[NOTE]
====
The `bean` PCD is supported only in Spring AOP and not in
native AspectJ weaving. It is a Spring-specific extension to the standard PCDs that
AspectJ defines and is, therefore, not available for aspects declared in the `@Aspect` model.
The `bean` PCD operates at the instance level (building on the Spring bean name
concept) rather than at the type level only (to which weaving-based AOP is limited).
Instance-based pointcut designators are a special capability of Spring's
proxy-based AOP framework and its close integration with the Spring bean factory, where
it is natural and straightforward to identify specific beans by name.
====
[[aop-pointcuts-combining]]
== Combining Pointcut Expressions
You can combine pointcut expressions by using `&&,` `||` and `!`. You can also refer to
pointcut expressions by name. The following example shows three pointcut expressions:
[tabs]
======

+
[source,java,indent=0,subs="verbatim",role="primary",chomp="-packages"]

@Pointcut("within(com.xyz.trading..*)")
public void inTrading() {} // <2>
@Pointcut("publicMethod() && inTrading()")
public void tradingOperation() {} // <3>
}
----
<1> `publicMethod` matches if a method execution join point represents the execution
of any public method.
<2> `inTrading` matches if a method execution is in the trading module.
<3> `tradingOperation` matches if a method execution represents any public method in the
trading module.
Kotlin::
+
[source,kotlin,indent=0,subs="verbatim",role="secondary",chomp="-packages"]
----
package com.xyz
class Pointcuts {
@Pointcut("execution(public * *(..))")
fun publicMethod() {} // <1>
@Pointcut("within(com.xyz.trading..*)")
fun inTrading() {} // <2>
@Pointcut("publicMethod() && inTrading()")
fun tradingOperation() {} // <3>
}
----
<1> `publicMethod` matches if a method execution join point represents the execution
of any public method.
<2> `inTrading` matches if a method execution is in the trading module.
<3> `tradingOperation` matches if a method execution represents any public method in the
trading module.
======
It is a best practice to build more complex pointcut expressions out of smaller _named
pointcuts_, as shown above. When referring to pointcuts by name, normal Java visibility
rules apply (you can see `private` pointcuts in the same type, `protected` pointcuts in
the hierarchy, `public` pointcuts anywhere, and so on). Visibility does not affect
pointcut matching.
[[aop-common-pointcuts]]
== Sharing Named Pointcut Definitions
When working with enterprise applications, developers often have the need to refer to
modules of the application and particular sets of operations from within several aspects.
We recommend defining a dedicated class that captures commonly used _named pointcut_
expressions for this purpose. Such a class typically resembles the following

== Examples
Spring AOP users are likely to use the `execution` pointcut designator the most often.
The format of an execution expression follows:
[literal,indent=0,subs="verbatim"]
----
execution(modifiers-pattern?
ret-type-pattern
declaring-type-pattern?name-pattern(param-pattern)
throws-pattern?)
----
All parts except the returning type pattern (`ret-type-pattern` in the preceding snippet),
the name pattern, and the parameters pattern are optional. The returning type pattern determines
what the return type of the method must be in order for a join point to be matched.
`{asterisk}` is most frequently used as the returning type pattern. It matches any return
type. A fully-qualified type name matches only when the method returns the given
type. The name pattern matches the method name. You can use the `{asterisk}` wildcard as all or
part of a name pattern. If you specify a declaring type pattern,
include a trailing `.` to join it to the name pattern component.
The parameters pattern is slightly more complex: `()` matches a
method that takes no parameters, whereas `(..)` matches any number (zero or more) of parameters.
The `({asterisk})` pattern matches a method that takes one parameter of any type.
`(*,String)` matches a method that takes two parameters. The first can be of any type, while the
second must be a `String`. Consult the

+
NOTE: `this` is more commonly used in a binding form. See the section on xref:core/aop/ataspectj/advice.adoc[Declaring Advice]

NOTE: You can also use `@annotation` in a binding form. See the xref:core/aop/ataspectj/advice.adoc[Declaring Advice] section
for how to make the annotation object available in the advice body.
* Any join point (method execution only in Spring AOP) which takes a single parameter,
and where the runtime type of the argument passed has the `@Classified` annotation:

[[writing-good-pointcuts]]
== Writing Good Pointcuts
During compilation, AspectJ processes pointcuts in order to optimize matching
performance. Examining code and determining if each join point matches (statically or
dynamically) a given pointcut is a costly process. (A dynamic match means the match
cannot be fully determined from static analysis and that a test is placed in the code to
determine if there is an actual match when the code is running). On first encountering a
pointcut declaration, AspectJ rewrites it into an optimal form for the matching
process. What does this mean? Basically, pointcuts are rewritten in DNF (Disjunctive
Normal Form) and the components of the pointcut are sorted such that those components
that are cheaper to evaluate are checked first. This means you do not have to worry
about understanding the performance of various pointcut designators and may supply them
in any order in a pointcut declaration.
However, AspectJ can work only with what it is told. For optimal performance of
matching, you should think about what you are trying to achieve and narrow the search
space for matches as much as possible in the definition. The existing designators
naturally fall into one of three groups: kinded, scoping, and contextual:
* Kinded designators select a particular kind of join point:
`execution`, `get`, `set`, `call`, and `handler`.
* Scoping designators select a group of join points of interest
(probably of many kinds): `within` and `withincode`
* Contextual designators match (and optionally bind) based on context:
`this`, `target`, and `@annotation`
A well written pointcut should include at least the first two types (kinded and
scoping). You can include the contextual designators to match based on
join point context or bind that context for use in the advice. Supplying only a
kinded designator or only a contextual designator works but could affect weaving
performance (time and memory used), due to extra processing and analysis. Scoping
designators are very fast to match, and using them means AspectJ can very quickly
dismiss groups of join points that should not be further processed. A good
pointcut should always include one if possible.

[[aop-choosing]]
= Choosing which AOP Declaration Style to Use
Once you have decided that an aspect is the best approach for implementing a given
requirement, how do you decide between using Spring AOP or AspectJ and between the
Aspect language (code) style, the @AspectJ annotation style, or the Spring XML style? These
decisions are influenced by a number of factors including application requirements,
development tools, and team familiarity with AOP.
[[aop-spring-or-aspectj]]
== Spring AOP or Full AspectJ?
Use the simplest thing that can work. Spring AOP is simpler than using full AspectJ, as
there is no requirement to introduce the AspectJ compiler / weaver into your development
and build processes. If you only need to advise the execution of operations on Spring
beans, Spring AOP is the right choice. If you need to advise objects not managed by
the Spring container (such as domain objects, typically), you need to use
AspectJ. You also need to use AspectJ if you wish to advise join points other than
simple method executions (for example, field get or set join points and so on).
When you use AspectJ, you have the choice of the AspectJ language syntax (also known as
the "code style") or the @AspectJ annotation style. If aspects play a large
role in your design, and you are able to use the https://www.eclipse.org/ajdt/[AspectJ
Development Tools (AJDT)] plugin for Eclipse, the AspectJ language syntax is the
preferred option. It is cleaner and simpler because the language was purposefully
designed for writing aspects. If you do not use Eclipse or have only a few aspects
that do not play a major role in your application, you may want to consider using
the @AspectJ style, sticking with regular Java compilation in your IDE, and adding
an aspect weaving phase to your build script.
[[aop-ataspectj-or-xml]]
== @AspectJ or XML for Spring AOP?
If you have chosen to use Spring AOP, you have a choice of @AspectJ or XML style.
There are various tradeoffs to consider.
The XML style may be most familiar to existing Spring users, and it is backed by genuine
POJOs. When using AOP as a tool to configure enterprise services, XML can be a good
choice (a good test is whether you consider the pointcut expression to be a part of your
configuration that you might want to change independently). With the XML style, it is
arguably clearer from your configuration which aspects are present in the system.
The XML style has two disadvantages. First, it does not fully encapsulate the
implementation of the requirement it addresses in a single place. The DRY principle says
that there should be a single, unambiguous, authoritative representation of any piece of
knowledge within a system. When using the XML style, the knowledge of how a requirement
is implemented is split across the declaration of the backing bean class and the XML in
the configuration file. When you use the @AspectJ style, this information is encapsulated
in a single module: the aspect. Secondly, the XML style is slightly more limited in what
it can express than the @AspectJ style: Only the "singleton" aspect instantiation model
is supported, and it is not possible to combine named pointcuts declared in XML.
For example, in the @AspectJ style you can write something like the following:
[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim",role="primary"]
----
@Pointcut("execution(* get*())")
public void propertyAccess() {}
@Pointcut("execution(com.xyz.Account+ *(..))")
public void operationReturningAnAccount() {}
@Pointcut("propertyAccess() && operationReturningAnAccount()")
public void accountPropertyAccess() {}
----
Kotlin::
+
[source,kotlin,indent=0,subs="verbatim",role="secondary"]
----
@Pointcut("execution(* get*())")
fun propertyAccess() {}
@Pointcut("execution(com.xyz.Account+ *(..))")
fun operationReturningAnAccount() {}
@Pointcut("propertyAccess() && operationReturningAnAccount()")
fun accountPropertyAccess() {}
----
======
In the XML style you can declare the first two pointcuts:
[source,xml,indent=0,subs="verbatim"]
----
<aop:pointcut id="propertyAccess"
expression="execution(* get*())"/>
<aop:pointcut id="operationReturningAnAccount"
expression="execution(com.xyz.Account+ *(..))"/>
----
The downside of the XML approach is that you cannot define the
`accountPropertyAccess` pointcut by combining these definitions.
The @AspectJ style supports additional instantiation models and richer pointcut
composition. It has the advantage of keeping the aspect as a modular unit. It also has
the advantage that the @AspectJ aspects can be understood (and thus consumed) both by
Spring AOP and by AspectJ. So, if you later decide you need the capabilities of AspectJ
to implement additional requirements, you can easily migrate to a classic AspectJ setup.
In general, the Spring team prefers the @AspectJ style for custom aspects beyond simple
configuration of enterprise services.

[[aop-introduction-defn]]
= AOP Concepts
Let us begin by defining some central AOP concepts and terminology. These terms are not
Spring-specific. Unfortunately, AOP terminology is not particularly intuitive.
However, it would be even more confusing if Spring used its own terminology.
* Aspect: A modularization of a concern that cuts across multiple classes.
Transaction management is a good example of a crosscutting concern in enterprise Java
applications. In Spring AOP, aspects are implemented by using regular classes
(the xref:core/aop/schema.adoc[schema-based approach]) or regular classes annotated with the
`@Aspect` annotation (the xref:core/aop/ataspectj.adoc[@AspectJ style]).
* Join point: A point during the execution of a program, such as the execution of a
method or the handling of an exception. In Spring AOP, a join point always
represents a method execution.
* Advice: Action taken by an aspect at a particular join point. Different types of
advice include "around", "before", and "after" advice. (Advice types are discussed
later.) Many AOP frameworks, including Spring, model an advice as an interceptor and
maintain a chain of interceptors around the join point.
* Pointcut: A predicate that matches join points. Advice is associated with a
pointcut expression and runs at any join point matched by the pointcut (for example,
the execution of a method with a certain name). The concept of join points as matched
by pointcut expressions is central to AOP, and Spring uses the AspectJ pointcut
expression language by default.
* Introduction: Declaring additional methods or fields on behalf of a type. Spring
AOP lets you introduce new interfaces (and a corresponding implementation) to any
advised object. For example, you could use an introduction to make a bean implement an
`IsModified` interface, to simplify caching. (An introduction is known as an
inter-type declaration in the AspectJ community.)
* Target object: An object being advised by one or more aspects. Also referred to as
the "advised object". Since Spring AOP is implemented by using runtime proxies, this
object is always a proxied object.
* AOP proxy: An object created by the AOP framework in order to implement the aspect
contracts (advice method executions and so on). In the Spring Framework, an AOP proxy
is a JDK dynamic proxy or a CGLIB proxy.
* Weaving: linking aspects with other application types or objects to create an
advised object. This can be done at compile time (using the AspectJ compiler, for
example), load time, or at runtime. Spring AOP, like other pure Java AOP frameworks,
performs weaving at runtime.
Spring AOP includes the following types of advice:
* Before advice: Advice that runs before a join point but that does not have
the ability to prevent execution flow proceeding to the join point (unless it throws
an exception).
* After returning advice: Advice to be run after a join point completes
normally (for example, if a method returns without throwing an exception).
* After throwing advice: Advice to be run if a method exits by throwing an
exception.
* After (finally) advice: Advice to be run regardless of the means by which a
join point exits (normal or exceptional return).
* Around advice: Advice that surrounds a join point such as a method invocation.
This is the most powerful kind of advice. Around advice can perform custom behavior
before and after the method invocation. It is also responsible for choosing whether to
proceed to the join point or to shortcut the advised method execution by returning its
own return value or throwing an exception.
Around advice is the most general kind of advice. Since Spring AOP, like AspectJ,
provides a full range of advice types, we recommend that you use the least powerful
advice type that can implement the required behavior. For example, if you need only to
update a cache with the return value of a method, you are better off implementing an
after returning advice than an around advice, although an around advice can accomplish
the same thing. Using the most specific advice type provides a simpler programming model
with less potential for errors. For example, you do not need to invoke the `proceed()`
method on the `JoinPoint` used for around advice, and, hence, you cannot fail to invoke it.
All advice parameters are statically typed so that you work with advice parameters of
the appropriate type (e.g. the type of the return value from a method execution) rather
than `Object` arrays.
The concept of join points matched by pointcuts is the key to AOP, which distinguishes
it from older technologies offering only interception. Pointcuts enable advice to be
targeted independently of the object-oriented hierarchy. For example, you can apply an
around advice providing declarative transaction management to a set of methods that span
multiple objects (such as all business operations in the service layer).

= AOP Proxies
:page-section-summary-toc: 1
Spring AOP defaults to using standard JDK dynamic proxies for AOP proxies. This
enables any interface (or set of interfaces) to be proxied.
Spring AOP can also use CGLIB proxies. This is necessary to proxy classes rather than
interfaces. By default, CGLIB is used if a business object does not implement an
interface. As it is good practice to program to interfaces rather than classes, business
classes normally implement one or more business interfaces. It is possible to
xref:core/aop/proxying.adoc[force the use of CGLIB], in those (hopefully rare) cases where you
need to advise a method that is not declared on an interface or where you need to
pass a proxied object to a method as a concrete type.
It is important to grasp the fact that Spring AOP is proxy-based. See
xref:core/aop/proxying.adoc#aop-understanding-aop-proxies[Understanding AOP Proxies] for a thorough examination of exactly what this
implementation detail actually means.

[[aop-introduction-spring-defn]]
= Spring AOP Capabilities and Goals
Spring AOP is implemented in pure Java. There is no need for a special compilation
process. Spring AOP does not need to control the class loader hierarchy and is thus
suitable for use in a servlet container or application server.
Spring AOP currently supports only method execution join points (advising the execution
of methods on Spring beans). Field interception is not implemented, although support for
field interception could be added without breaking the core Spring AOP APIs. If you need
to advise field access and update join points, consider a language such as AspectJ.
Spring AOP's approach to AOP differs from that of most other AOP frameworks. The aim is
not to provide the most complete AOP implementation (although Spring AOP is quite
capable). Rather, the aim is to provide a close integration between AOP implementation and
Spring IoC, to help solve common problems in enterprise applications.
Thus, for example, the Spring Framework's AOP functionality is normally used in
conjunction with the Spring IoC container. Aspects are configured by using normal bean
definition syntax (although this allows powerful "auto-proxying" capabilities). This is a
crucial difference from other AOP implementations. You cannot do some things
easily or efficiently with Spring AOP, such as advise very fine-grained objects (typically,
domain objects). AspectJ is the best choice in such cases. However, our
experience is that Spring AOP provides an excellent solution to most problems in
enterprise Java applications that are amenable to AOP.
Spring AOP never strives to compete with AspectJ to provide a comprehensive AOP
solution. We believe that both proxy-based frameworks such as Spring AOP and full-blown
frameworks such as AspectJ are valuable and that they are complementary, rather than in
competition. Spring seamlessly integrates Spring AOP and IoC with AspectJ, to enable
all uses of AOP within a consistent Spring-based application
architecture. This integration does not affect the Spring AOP API or the AOP Alliance
API. Spring AOP remains backward-compatible. See xref:core/aop-api.adoc[the following chapter]
for a discussion of the Spring AOP APIs.
[NOTE]
====
One of the central tenets of the Spring Framework is that of non-invasiveness. This
is the idea that you should not be forced to introduce framework-specific classes and
interfaces into your business or domain model. However, in some places, the Spring Framework
does give you the option to introduce Spring Framework-specific dependencies into your
codebase. The rationale in giving you such options is because, in certain scenarios, it
might be just plain easier to read or code some specific piece of functionality in such
a way. However, the Spring Framework (almost) always offers you the choice: You have the
freedom to make an informed decision as to which option best suits your particular use
case or scenario.
One such choice that is relevant to this chapter is that of which AOP framework (and
which AOP style) to choose. You have the choice of AspectJ, Spring AOP, or both. You
also have the choice of either the @AspectJ annotation-style approach or the Spring XML
configuration-style approach. The fact that this chapter chooses to introduce the
@AspectJ-style approach first should not be taken as an indication that the Spring team
favors the @AspectJ annotation-style approach over the Spring XML configuration-style.
See xref:core/aop/choosing.adoc[Choosing which AOP Declaration Style to Use] for a more complete discussion of the advantages and disadvantages of
each style.

[[aop-proxying]]
= Proxying Mechanisms
Spring AOP uses either JDK dynamic proxies or CGLIB to create the proxy for a given
target object. JDK dynamic proxies are built into the JDK, whereas CGLIB is a common
open-source class definition library (repackaged into `spring-core`).
If the target object to be proxied implements at least one interface, a JDK dynamic
proxy is used. All of the interfaces implemented by the target type are proxied.
If the target object does not implement any interfaces, a CGLIB proxy is created.
If you want to force the use of CGLIB proxying (for example, to proxy every method
defined for the target object, not only those implemented by its interfaces),
you can do so. However, you should consider the following issues:
* With CGLIB, `final` methods cannot be advised, as they cannot be overridden in
runtime-generated subclasses.
* As of Spring 4.0, the constructor of your proxied object is NOT called twice anymore,
since the CGLIB proxy instance is created through Objenesis. Only if your JVM does
not allow for constructor bypassing, you might see double invocations and
corresponding debug log entries from Spring's AOP support.
* Your CGLIB proxy usage may face limitations with the JDK 9+ platform module system.
As a typical case, you cannot create a CGLIB proxy for a class from the `java.lang`
package when deploying on the module path. Such cases require a JVM bootstrap flag
`--add-opens=java.base/java.lang=ALL-UNNAMED` which is not available for modules.
To force the use of CGLIB proxies, set the value of the `proxy-target-class` attribute
of the `<aop:config>` element to true, as follows:
[source,xml,indent=0,subs="verbatim"]
----
<aop:config proxy-target-class="true">
<!-- other beans defined here... -->
</aop:config>
----
To force CGLIB proxying when you use the @AspectJ auto-proxy support, set the
`proxy-target-class` attribute of the `<aop:aspectj-autoproxy>` element to `true`,
as follows:
[source,xml,indent=0,subs="verbatim"]
----
<aop:aspectj-autoproxy proxy-target-class="true"/>
----
[NOTE]
====
Multiple `<aop:config/>` sections are collapsed into a single unified auto-proxy creator
at runtime, which applies the _strongest_ proxy settings that any of the
`<aop:config/>` sections (typically from different XML bean definition files) specified.
This also applies to the `<tx:annotation-driven/>` and `<aop:aspectj-autoproxy/>`
elements.
To be clear, using `proxy-target-class="true"` on `<tx:annotation-driven/>`,
`<aop:aspectj-autoproxy/>`, or `<aop:config/>` elements forces the use of CGLIB
proxies _for all three of them_.

[[aop-understanding-aop-proxies]]
== Understanding AOP Proxies
Spring AOP is proxy-based. It is vitally important that you grasp the semantics of
what that last statement actually means before you write your own aspects or use any of
the Spring AOP-based aspects supplied with the Spring Framework.
Consider first the scenario where you have a plain-vanilla, un-proxied,
nothing-special-about-it, straight object reference, as the following
code snippet shows:
[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim",role="primary"]
----
public class SimplePojo implements Pojo {
public void foo() {
// this next method invocation is a direct call on the 'this' reference
this.bar();
}
public void bar() {
// some logic...
}
}
----
Kotlin::
+
[source,kotlin,indent=0,subs="verbatim",role="secondary"]
----
class SimplePojo : Pojo {
fun foo() {
// this next method invocation is a direct call on the 'this' reference
this.bar()
}
fun bar() {
// some logic...
}
}
----
======
If you invoke a method on an object reference, the method is invoked directly on
that object reference, as the following image and listing show:
image::aop-proxy-plain-pojo-call.png[]
[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim",role="primary"]
----
public class Main {
public static void main(String[] args) {
Pojo pojo = new SimplePojo();
// this is a direct method call on the 'pojo' reference
pojo.foo();
}
}
----
Kotlin::
+
[source,kotlin,indent=0,subs="verbatim",role="secondary"]
----
fun main() {
val pojo = SimplePojo()
// this is a direct method call on the 'pojo' reference
pojo.foo()
}
----
======
Things change slightly when the reference that client code has is a proxy. Consider the
following diagram and code snippet:
image::aop-proxy-call.png[]
[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim",role="primary"]
----
public class Main {
public static void main(String[] args) {
ProxyFactory factory = new ProxyFactory(new SimplePojo());
factory.addInterface(Pojo.class);
factory.addAdvice(new RetryAdvice());
Pojo pojo = (Pojo) factory.getProxy();
// this is a method call on the proxy!
pojo.foo();
}
}
----
Kotlin::
+
[source,kotlin,indent=0,subs="verbatim",role="secondary"]
----
fun main() {
val factory = ProxyFactory(SimplePojo())
factory.addInterface(Pojo::class.java)
factory.addAdvice(RetryAdvice())
val pojo = factory.proxy as Pojo
// this is a method call on the proxy!
pojo.foo()
}
----
======
The key thing to understand here is that the client code inside the `main(..)` method
of the `Main` class has a reference to the proxy. This means that method calls on that
object reference are calls on the proxy. As a result, the proxy can delegate to all of
the interceptors (advice) that are relevant to that particular method call. However,
once the call has finally reached the target object (the `SimplePojo` reference in
this case), any method calls that it may make on itself, such as `this.bar()` or
`this.foo()`, are going to be invoked against the `this` reference, and not the proxy.
This has important implications. It means that self-invocation is not going to result
in the advice associated with a method invocation getting a chance to run.
Okay, so what is to be done about this? The best approach (the term "best" is used
loosely here) is to refactor your code such that the self-invocation does not happen.
This does entail some work on your part, but it is the best, least-invasive approach.
The next approach is absolutely horrendous, and we hesitate to point it out, precisely
because it is so horrendous. You can (painful as it is to us) totally tie the logic
within your class to Spring AOP, as the following example shows:
[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim",role="primary"]
----
public class SimplePojo implements Pojo {
public void foo() {
// this works, but... gah!
((Pojo) AopContext.currentProxy()).bar();
}
public void bar() {
// some logic...
}
}
----
Kotlin::
+
[source,kotlin,indent=0,subs="verbatim",role="secondary"]
----
class SimplePojo : Pojo {
fun foo() {
// this works, but... gah!
(AopContext.currentProxy() as Pojo).bar()
}
fun bar() {
// some logic...
}
}
----
======
This totally couples your code to Spring AOP, and it makes the class itself aware of
the fact that it is being used in an AOP context, which flies in the face of AOP. It
also requires some additional configuration when the proxy is being created, as the
following example shows:
[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim",role="primary"]
----
public class Main {
public static void main(String[] args) {
ProxyFactory factory = new ProxyFactory(new SimplePojo());
factory.addInterface(Pojo.class);
factory.addAdvice(new RetryAdvice());
factory.setExposeProxy(true);
Pojo pojo = (Pojo) factory.getProxy();
// this is a method call on the proxy!
pojo.foo();
}
}
----
Kotlin::
+
[source,kotlin,indent=0,subs="verbatim",role="secondary"]
----
fun main() {
val factory = ProxyFactory(SimplePojo())
factory.addInterface(Pojo::class.java)
factory.addAdvice(RetryAdvice())
factory.isExposeProxy = true
val pojo = factory.proxy as Pojo
// this is a method call on the proxy!
pojo.foo()
}
----
======
Finally, it must be noted that AspectJ does not have this self-invocation issue because
it is not a proxy-based AOP framework.

[[aop-schema]]
= Schema-based AOP Support
If you prefer an XML-based format, Spring also offers support for defining aspects
using the `aop` namespace tags. The exact same pointcut expressions and advice kinds
as when using the @AspectJ style are supported. Hence, in this section we focus on
that syntax and refer the reader to the discussion in the previous section
(xref:core/aop/ataspectj.adoc[@AspectJ support]) for an understanding of writing pointcut expressions and the binding
of advice parameters.
To use the aop namespace tags described in this section, you need to import the
`spring-aop` schema, as described in xref:core/appendix/xsd-schemas.adoc[XML Schema-based configuration]
. See xref:core/appendix/xsd-schemas.adoc#aop[the AOP schema]
for how to import the tags in the `aop` namespace.
Within your Spring configurations, all aspect and advisor elements must be placed within
an `<aop:config>` element (you can have more than one `<aop:config>` element in an
application context configuration). An `<aop:config>` element can contain pointcut,
advisor, and aspect elements (note that these must be declared in that order).
WARNING: The `<aop:config>` style of configuration makes heavy use of Spring's
xref:core/aop-api/autoproxy.adoc[auto-proxying] mechanism. This can cause issues (such as advice
not being woven) if you already use explicit auto-proxying through the use of
`BeanNameAutoProxyCreator` or something similar. The recommended usage pattern is to
use either only the `<aop:config>` style or only the `AutoProxyCreator` style and
never mix them.
[[aop-schema-declaring-an-aspect]]
== Declaring an Aspect
When you use the schema support, an aspect is a regular Java object defined as a bean in
your Spring application context. The state and behavior are captured in the fields and
methods of the object, and the pointcut and advice information are captured in the XML.
You can declare an aspect by using the `<aop:aspect>` element, and reference the backing bean
by using the `ref` attribute, as the following example shows:
[source,xml,indent=0,subs="verbatim"]
----
<aop:config>
<aop:aspect id="myAspect" ref="aBean">
...
</aop:aspect>
</aop:config>
<bean id="aBean" class="...">
...
</bean>
----
The bean that backs the aspect (`aBean` in this case) can of course be configured and
dependency injected just like any other Spring bean.
[[aop-schema-pointcuts]]
== Declaring a Pointcut
You can declare a _named pointcut_ inside an `<aop:config>` element, letting the pointcut
definition be shared across several aspects and advisors.
A pointcut that represents the execution of any business service in the service layer can
be defined as follows:
[source,xml,indent=0,subs="verbatim"]
----
<aop:config>
<aop:pointcut id="businessService"
expression="execution(* com.xyz.service.*.*(..))" />
</aop:config>
----
Note that the pointcut expression itself uses the same AspectJ pointcut expression
language as described in xref:core/aop/ataspectj.adoc[@AspectJ support]. If you use the schema based declaration
style, you can also refer to _named pointcuts_ defined in `@Aspect` types within the
pointcut expression. Thus, another way of defining the above pointcut would be as follows:
[source,xml,indent=0,subs="verbatim"]
----
<aop:config>
<aop:pointcut id="businessService"
expression="com.xyz.CommonPointcuts.businessService()" /> <1>
</aop:config>
----
<1> References the `businessService` named pointcut defined in xref:core/aop/ataspectj/pointcuts.adoc#aop-common-pointcuts[Sharing Named Pointcut Definitions].
Declaring a pointcut _inside_ an aspect is very similar to declaring a top-level pointcut,
as the following example shows:
[source,xml,indent=0,subs="verbatim"]
----
<aop:config>
<aop:aspect id="myAspect" ref="aBean">
<aop:pointcut id="businessService"
expression="execution(* com.xyz.service.*.*(..))"/>
...
</aop:aspect>
</aop:config>
----
In much the same way as an @AspectJ aspect, pointcuts declared by using the schema based
definition style can collect join point context. For example, the following pointcut
collects the `this` object as the join point context and passes it to the advice:
[source,xml,indent=0,subs="verbatim"]
----
<aop:config>
<aop:aspect id="myAspect" ref="aBean">
<aop:pointcut id="businessService"
expression="execution(* com.xyz.service.*.*(..)) &amp;&amp; this(service)"/>
<aop:before pointcut-ref="businessService" method="monitor"/>
...
</aop:aspect>
</aop:config>
----
The advice must be declared to receive the collected join point context by including
parameters of the matching names, as follows:
[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim",role="primary"]
----
public void monitor(Object service) {
// ...
}
----
Kotlin::
+
[source,kotlin,indent=0,subs="verbatim",role="secondary"]
----
fun monitor(service: Any) {
// ...
}
----
======
When combining pointcut sub-expressions, `+&amp;&amp;+` is awkward within an XML
document, so you can use the `and`, `or`, and `not` keywords in place of `+&amp;&amp;+`,
`||`, and `!`, respectively. For example, the previous pointcut can be better written as
follows:
[source,xml,indent=0,subs="verbatim"]
----
<aop:config>
<aop:aspect id="myAspect" ref="aBean">
<aop:pointcut id="businessService"
expression="execution(* com.xyz.service.*.*(..)) and this(service)"/>
<aop:before pointcut-ref="businessService" method="monitor"/>
...
</aop:aspect>
</aop:config>
----
Note that pointcuts defined in this way are referred to by their XML `id` and cannot be
used as named pointcuts to form composite pointcuts. The named pointcut support in the
schema-based definition style is thus more limited than that offered by the @AspectJ
style.
[[aop-schema-advice]]
== Declaring Advice
The schema-based AOP support uses the same five kinds of advice as the @AspectJ style, and they have
exactly the same semantics.
[[aop-schema-advice-before]]
=== Before Advice
Before advice runs before a matched method execution. It is declared inside an
`<aop:aspect>` by using the `<aop:before>` element, as the following example shows:
[source,xml,indent=0,subs="verbatim"]
----
<aop:aspect id="beforeExample" ref="aBean">
<aop:before
pointcut-ref="dataAccessOperation"
method="doAccessCheck"/>
...
</aop:aspect>
----
In the example above, `dataAccessOperation` is the `id` of a _named pointcut_ defined at
the top (`<aop:config>`) level (see xref:core/aop/schema.adoc#aop-schema-pointcuts[Declaring a Pointcut]).
NOTE: As we noted in the discussion of the @AspectJ style, using _named pointcuts_ can
significantly improve the readability of your code. See xref:core/aop/ataspectj/pointcuts.adoc#aop-common-pointcuts[Sharing Named Pointcut Definitions] for
details.
To define the pointcut inline instead, replace the `pointcut-ref` attribute with a
`pointcut` attribute, as follows:
[source,xml,indent=0,subs="verbatim"]
----
<aop:aspect id="beforeExample" ref="aBean">
<aop:before
pointcut="execution(* com.xyz.dao.*.*(..))"
method="doAccessCheck"/>
...
</aop:aspect>
----
The `method` attribute identifies a method (`doAccessCheck`) that provides the body of
the advice. This method must be defined for the bean referenced by the aspect element
that contains the advice. Before a data access operation is performed (a method execution
join point matched by the pointcut expression), the `doAccessCheck` method on the aspect
bean is invoked.
[[aop-schema-advice-after-returning]]
=== After Returning Advice
After returning advice runs when a matched method execution completes normally. It is
declared inside an `<aop:aspect>` in the same way as before advice. The following example
shows how to declare it:
[source,xml,indent=0,subs="verbatim"]
----
<aop:aspect id="afterReturningExample" ref="aBean">
<aop:after-returning
pointcut="execution(* com.xyz.dao.*.*(..))"
method="doAccessCheck"/>
...
</aop:aspect>
----
As in the @AspectJ style, you can get the return value within the advice body.
To do so, use the `returning` attribute to specify the name of the parameter to which
the return value should be passed, as the following example shows:
[source,xml,indent=0,subs="verbatim"]
----
<aop:aspect id="afterReturningExample" ref="aBean">
<aop:after-returning
pointcut="execution(* com.xyz.dao.*.*(..))"
returning="retVal"
method="doAccessCheck"/>
...
</aop:aspect>
----
The `doAccessCheck` method must declare a parameter named `retVal`. The type of this
parameter constrains matching in the same way as described for `@AfterReturning`. For
example, you can declare the method signature as follows:
[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim",role="primary"]
----
public void doAccessCheck(Object retVal) {...
----
Kotlin::
+
[source,kotlin,indent=0,subs="verbatim",role="secondary"]
----
fun doAccessCheck(retVal: Any) {...
----
======
[[aop-schema-advice-after-throwing]]
=== After Throwing Advice
After throwing advice runs when a matched method execution exits by throwing an
exception. It is declared inside an `<aop:aspect>` by using the `after-throwing` element,
as the following example shows:
[source,xml,indent=0,subs="verbatim"]
----
<aop:aspect id="afterThrowingExample" ref="aBean">
<aop:after-throwing
pointcut="execution(* com.xyz.dao.*.*(..))"
method="doRecoveryActions"/>
...
</aop:aspect>
----
As in the @AspectJ style, you can get the thrown exception within the advice body.
To do so, use the `throwing` attribute to specify the name of the parameter to
which the exception should be passed as the following example shows:
[source,xml,indent=0,subs="verbatim"]
----
<aop:aspect id="afterThrowingExample" ref="aBean">
<aop:after-throwing
pointcut="execution(* com.xyz.dao.*.*(..))"
throwing="dataAccessEx"
method="doRecoveryActions"/>
...
</aop:aspect>
----
The `doRecoveryActions` method must declare a parameter named `dataAccessEx`.
The type of this parameter constrains matching in the same way as described for
`@AfterThrowing`. For example, the method signature may be declared as follows:
[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim",role="primary"]
----
public void doRecoveryActions(DataAccessException dataAccessEx) {...
----
Kotlin::
+
[source,kotlin,indent=0,subs="verbatim",role="secondary"]
----
fun doRecoveryActions(dataAccessEx: DataAccessException) {...
----
======
[[aop-schema-advice-after-finally]]
=== After (Finally) Advice
After (finally) advice runs no matter how a matched method execution exits.
You can declare it by using the `after` element, as the following example shows:
[source,xml,indent=0,subs="verbatim"]
----
<aop:aspect id="afterFinallyExample" ref="aBean">
<aop:after
pointcut="execution(* com.xyz.dao.*.*(..))"
method="doReleaseLock"/>
...
</aop:aspect>
----
[[aop-schema-advice-around]]
=== Around Advice
The last kind of advice is _around_ advice. Around advice runs "around" a matched
method's execution. It has the opportunity to do work both before and after the method
runs and to determine when, how, and even if the method actually gets to run at all.
Around advice is often used if you need to share state before and after a method
execution in a thread-safe manner for example, starting and stopping a timer.
[TIP]
====
Always use the least powerful form of advice that meets your requirements.
For example, do not use _around_ advice if _before_ advice is sufficient for your needs.
====
You can declare around advice by using the `aop:around` element. The advice method should
declare `Object` as its return type, and the first parameter of the method must be of
type `ProceedingJoinPoint`. Within the body of the advice method, you must invoke
`proceed()` on the `ProceedingJoinPoint` in order for the underlying method to run.
Invoking `proceed()` without arguments will result in the caller's original arguments
being supplied to the underlying method when it is invoked. For advanced use cases, there
is an overloaded variant of the `proceed()` method which accepts an array of arguments
(`Object[]`). The values in the array will be used as the arguments to the underlying
method when it is invoked. See xref:core/aop/ataspectj/advice.adoc#aop-ataspectj-around-advice[Around Advice] for notes on calling
`proceed` with an `Object[]`.
The following example shows how to declare around advice in XML:
[source,xml,indent=0,subs="verbatim"]
----
<aop:aspect id="aroundExample" ref="aBean">
<aop:around
pointcut="execution(* com.xyz.service.*.*(..))"
method="doBasicProfiling"/>
...
</aop:aspect>
----
The implementation of the `doBasicProfiling` advice can be exactly the same as in the
@AspectJ example (minus the annotation, of course), as the following example shows:
[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim",role="primary"]
----
public Object doBasicProfiling(ProceedingJoinPoint pjp) throws Throwable {
// start stopwatch
Object retVal = pjp.proceed();
// stop stopwatch
return retVal;
}
----
Kotlin::
+
[source,kotlin,indent=0,subs="verbatim",role="secondary"]
----
fun doBasicProfiling(pjp: ProceedingJoinPoint): Any? {
// start stopwatch
val retVal = pjp.proceed()
// stop stopwatch
return pjp.proceed()
}
----
======
[[aop-schema-params]]
=== Advice Parameters
The schema-based declaration style supports fully typed advice in the same way as
described for the @AspectJ support -- by matching pointcut parameters by name against
advice method parameters. See xref:core/aop/ataspectj/advice.adoc#aop-ataspectj-advice-params[Advice Parameters] for details. If you wish
to explicitly specify argument names for the advice methods (not relying on the
detection strategies previously described), you can do so by using the `arg-names`
attribute of the advice element, which is treated in the same manner as the `argNames`
attribute in an advice annotation (as described in xref:core/aop/ataspectj/advice.adoc#aop-ataspectj-advice-params-names[Determining Argument Names]).
The following example shows how to specify an argument name in XML:
[source,xml,indent=0,subs="verbatim"]
----
<aop:before
pointcut="com.xyz.Pointcuts.publicMethod() and @annotation(auditable)" <1>
method="audit"
arg-names="auditable" />
----
<1> References the `publicMethod` named pointcut defined in xref:core/aop/ataspectj/pointcuts.adoc#aop-pointcuts-combining[Combining Pointcut Expressions].
The `arg-names` attribute accepts a comma-delimited list of parameter names.
The following slightly more involved example of the XSD-based approach shows
some around advice used in conjunction with a number of strongly typed parameters:
[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim",role="primary",chomp="-packages"]
----
package com.xyz.service;
public interface PersonService {
Person getPerson(String personName, int age);
}
public class DefaultPersonService implements PersonService {
public Person getPerson(String name, int age) {
return new Person(name, age);
}
}
----
Kotlin::
+
[source,kotlin,indent=0,subs="verbatim",role="secondary",chomp="-packages"]
----
package com.xyz.service
interface PersonService {
fun getPerson(personName: String, age: Int): Person
}
class DefaultPersonService : PersonService {
fun getPerson(name: String, age: Int): Person {
return Person(name, age)
}
}
----
======
Next up is the aspect. Notice the fact that the `profile(..)` method accepts a number of
strongly-typed parameters, the first of which happens to be the join point used to
proceed with the method call. The presence of this parameter is an indication that the
`profile(..)` is to be used as `around` advice, as the following example shows:
[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim",role="primary",chomp="-packages"]
----
package com.xyz;
import org.aspectj.lang.ProceedingJoinPoint;
import org.springframework.util.StopWatch;
public class SimpleProfiler {
public Object profile(ProceedingJoinPoint call, String name, int age) throws Throwable {
StopWatch clock = new StopWatch("Profiling for '" + name + "' and '" + age + "'");
try {
clock.start(call.toShortString());
return call.proceed();
} finally {
clock.stop();
System.out.println(clock.prettyPrint());
}
}
}
----
Kotlin::
+
[source,kotlin,indent=0,subs="verbatim",role="secondary",chomp="-packages"]
----
package com.xyz
import org.aspectj.lang.ProceedingJoinPoint
import org.springframework.util.StopWatch
class SimpleProfiler {
fun profile(call: ProceedingJoinPoint, name: String, age: Int): Any? {
val clock = StopWatch("Profiling for '$name' and '$age'")
try {
clock.start(call.toShortString())
return call.proceed()
} finally {
clock.stop()
println(clock.prettyPrint())
}
}
}
----
======
Finally, the following example XML configuration effects the execution of the
preceding advice for a particular join point:
[source,xml,indent=0,subs="verbatim"]
----
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:aop="http://www.springframework.org/schema/aop"
xsi:schemaLocation="
http://www.springframework.org/schema/beans
https://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/aop
https://www.springframework.org/schema/aop/spring-aop.xsd">
<!-- this is the object that will be proxied by Spring's AOP infrastructure -->
<bean id="personService" class="com.xyz.service.DefaultPersonService"/>
<!-- this is the actual advice itself -->
<bean id="profiler" class="com.xyz.SimpleProfiler"/>
<aop:config>
<aop:aspect ref="profiler">
<aop:pointcut id="theExecutionOfSomePersonServiceMethod"
expression="execution(* com.xyz.service.PersonService.getPerson(String,int))
and args(name, age)"/>
<aop:around pointcut-ref="theExecutionOfSomePersonServiceMethod"
method="profile"/>
</aop:aspect>
</aop:config>
</beans>
----
Consider the following driver script:
[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim",role="primary"]
----
public class Boot {
public static void main(String[] args) {
ApplicationContext ctx = new ClassPathXmlApplicationContext("beans.xml");
PersonService person = ctx.getBean(PersonService.class);
person.getPerson("Pengo", 12);
}
}
----
Kotlin::
+
[source,kotlin,indent=0,subs="verbatim",role="secondary"]
----
fun main() {
val ctx = ClassPathXmlApplicationContext("beans.xml")
val person = ctx.getBean(PersonService.class)
person.getPerson("Pengo", 12)
}
----
======
With such a `Boot` class, we would get output similar to the following on standard output:
[literal,subs="verbatim"]
----
StopWatch 'Profiling for 'Pengo' and '12': running time (millis) = 0
-----------------------------------------
ms % Task name
-----------------------------------------
00000 ? execution(getFoo)
----
[[aop-ordering]]
=== Advice Ordering
When multiple pieces of advice need to run at the same join point (executing method)
the ordering rules are as described in xref:core/aop/ataspectj/advice.adoc#aop-ataspectj-advice-ordering[Advice Ordering]. The precedence
between aspects is determined via the `order` attribute in the `<aop:aspect>` element or
by either adding the `@Order` annotation to the bean that backs the aspect or by having
the bean implement the `Ordered` interface.
[NOTE]
====
In contrast to the precedence rules for advice methods defined in the same `@Aspect`
class, when two pieces of advice defined in the same `<aop:aspect>` element both need to
run at the same join point, the precedence is determined by the order in which the advice
elements are declared within the enclosing `<aop:aspect>` element, from highest to lowest
precedence.
For example, given an `around` advice and a `before` advice defined in the same
`<aop:aspect>` element that apply to the same join point, to ensure that the `around`
advice has higher precedence than the `before` advice, the `<aop:around>` element must be
declared before the `<aop:before>` element.
As a general rule of thumb, if you find that you have multiple pieces of advice defined
in the same `<aop:aspect>` element that apply to the same join point, consider collapsing
such advice methods into one advice method per join point in each `<aop:aspect>` element
or refactor the pieces of advice into separate `<aop:aspect>` elements that you can order
at the aspect level.
====
[[aop-schema-introductions]]
== Introductions
Introductions (known as inter-type declarations in AspectJ) let an aspect declare
that advised objects implement a given interface and provide an implementation of
that interface on behalf of those objects.
You can make an introduction by using the `aop:declare-parents` element inside an `aop:aspect`.
You can use the `aop:declare-parents` element to declare that matching types have a new parent (hence the name).
For example, given an interface named `UsageTracked` and an implementation of that interface named
`DefaultUsageTracked`, the following aspect declares that all implementors of service
interfaces also implement the `UsageTracked` interface. (In order to expose statistics
through JMX for example.)
[source,xml,indent=0,subs="verbatim"]
----
<aop:aspect id="usageTrackerAspect" ref="usageTracking">
<aop:declare-parents
types-matching="com.xyz.service.*+"
implement-interface="com.xyz.service.tracking.UsageTracked"
default-impl="com.xyz.service.tracking.DefaultUsageTracked"/>
<aop:before
pointcut="execution(* com.xyz..service.*.*(..))
and this(usageTracked)"
method="recordUsage"/>
</aop:aspect>
----
The class that backs the `usageTracking` bean would then contain the following method:
[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim",role="primary"]
----
public void recordUsage(UsageTracked usageTracked) {
usageTracked.incrementUseCount();
}
----
Kotlin::
+
[source,kotlin,indent=0,subs="verbatim",role="secondary"]
----
fun recordUsage(usageTracked: UsageTracked) {
usageTracked.incrementUseCount()
}
----
======
The interface to be implemented is determined by the `implement-interface` attribute. The
value of the `types-matching` attribute is an AspectJ type pattern. Any bean of a
matching type implements the `UsageTracked` interface. Note that, in the before
advice of the preceding example, service beans can be directly used as implementations of
the `UsageTracked` interface. To access a bean programmatically, you could write the
following:
[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim",role="primary"]
----
UsageTracked usageTracked = context.getBean("myService", UsageTracked.class);
----
Kotlin::
+
[source,kotlin,indent=0,subs="verbatim",role="secondary"]
----
val usageTracked = context.getBean("myService", UsageTracked.class)
----
======
[[aop-schema-instantiation-models]]
== Aspect Instantiation Models
The only supported instantiation model for schema-defined aspects is the singleton
model. Other instantiation models may be supported in future releases.
[[aop-schema-advisors]]
== Advisors
The concept of "advisors" comes from the AOP support defined in Spring
and does not have a direct equivalent in AspectJ. An advisor is like a small
self-contained aspect that has a single piece of advice. The advice itself is
represented by a bean and must implement one of the advice interfaces described in
xref:core/aop-api/advice.adoc#aop-api-advice-types[Advice Types in Spring]. Advisors can take advantage of AspectJ pointcut expressions.
Spring supports the advisor concept with the `<aop:advisor>` element. You most
commonly see it used in conjunction with transactional advice, which also has its own
namespace support in Spring. The following example shows an advisor:
[source,xml,indent=0,subs="verbatim"]
----
<aop:config>
<aop:pointcut id="businessService"
expression="execution(* com.xyz.service.*.*(..))"/>
<aop:advisor
pointcut-ref="businessService"
advice-ref="tx-advice" />
</aop:config>
<tx:advice id="tx-advice">
<tx:attributes>
<tx:method name="*" propagation="REQUIRED"/>
</tx:attributes>
</tx:advice>
----
As well as the `pointcut-ref` attribute used in the preceding example, you can also use the
`pointcut` attribute to define a pointcut expression inline.
To define the precedence of an advisor so that the advice can participate in ordering,
use the `order` attribute to define the `Ordered` value of the advisor.
[[aop-schema-example]]
== An AOP Schema Example
This section shows how the concurrent locking failure retry example from
xref:core/aop/ataspectj/example.adoc[An AOP Example] looks when rewritten with the schema support.
The execution of business services can sometimes fail due to concurrency issues (for
example, a deadlock loser). If the operation is retried, it is likely to succeed
on the next try. For business services where it is appropriate to retry in such
conditions (idempotent operations that do not need to go back to the user for conflict
resolution), we want to transparently retry the operation to avoid the client seeing a
`PessimisticLockingFailureException`. This is a requirement that clearly cuts across
multiple services in the service layer and, hence, is ideal for implementing through an
aspect.
Because we want to retry the operation, we need to use around advice so that we can
call `proceed` multiple times. The following listing shows the basic aspect implementation
(which is a regular Java class that uses the schema support):
[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim",role="primary"]
----
public class ConcurrentOperationExecutor implements Ordered {
private static final int DEFAULT_MAX_RETRIES = 2;
private int maxRetries = DEFAULT_MAX_RETRIES;
private int order = 1;
public void setMaxRetries(int maxRetries) {
this.maxRetries = maxRetries;
}
public int getOrder() {
return this.order;
}
public void setOrder(int order) {
this.order = order;
}
public Object doConcurrentOperation(ProceedingJoinPoint pjp) throws Throwable {
int numAttempts = 0;
PessimisticLockingFailureException lockFailureException;
do {
numAttempts++;
try {
return pjp.proceed();
}
catch(PessimisticLockingFailureException ex) {
lockFailureException = ex;
}
} while(numAttempts <= this.maxRetries);
throw lockFailureException;
}
}
----
Kotlin::
+
[source,kotlin,indent=0,subs="verbatim",role="secondary"]
----
class ConcurrentOperationExecutor : Ordered {
private val DEFAULT_MAX_RETRIES = 2
private var maxRetries = DEFAULT_MAX_RETRIES
private var order = 1
fun setMaxRetries(maxRetries: Int) {
this.maxRetries = maxRetries
}
override fun getOrder(): Int {
return this.order
}
fun setOrder(order: Int) {
this.order = order
}
fun doConcurrentOperation(pjp: ProceedingJoinPoint): Any? {
var numAttempts = 0
var lockFailureException: PessimisticLockingFailureException
do {
numAttempts++
try {
return pjp.proceed()
} catch (ex: PessimisticLockingFailureException) {
lockFailureException = ex
}
} while (numAttempts <= this.maxRetries)
throw lockFailureException
}
}
----
======
Note that the aspect implements the `Ordered` interface so that we can set the precedence of
the aspect higher than the transaction advice (we want a fresh transaction each time we
retry). The `maxRetries` and `order` properties are both configured by Spring. The
main action happens in the `doConcurrentOperation` around advice method. We try to
proceed. If we fail with a `PessimisticLockingFailureException`, we try again,
unless we have exhausted all of our retry attempts.
NOTE: This class is identical to the one used in the @AspectJ example, but with the
annotations removed.
The corresponding Spring configuration is as follows:
[source,xml,indent=0,subs="verbatim"]
----
<aop:config>
<aop:aspect id="concurrentOperationRetry" ref="concurrentOperationExecutor">
<aop:pointcut id="idempotentOperation"
expression="execution(* com.xyz.service.*.*(..))"/>
<aop:around
pointcut-ref="idempotentOperation"
method="doConcurrentOperation"/>
</aop:aspect>
</aop:config>
<bean id="concurrentOperationExecutor"
class="com.xyz.service.impl.ConcurrentOperationExecutor">

Notice that, for the time being, we assume that all business services are idempotent. If
this is not the case, we can refine the aspect so that it retries only genuinely
idempotent operations, by introducing an `Idempotent` annotation and using the annotation
to annotate the implementation of service operations, as the following example shows:
[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim",role="primary"]
----
@Retention(RetentionPolicy.RUNTIME)
// marker annotation
public @interface Idempotent {
}
----
Kotlin::
+
[source,kotlin,indent=0,subs="verbatim",role="secondary"]
----
@Retention(AnnotationRetention.RUNTIME)
// marker annotation
annotation class Idempotent
----
======
The
change to the aspect to retry only idempotent operations involves refining the
pointcut expression so that only `@Idempotent` operations match, as follows:
[source,xml,indent=0,subs="verbatim"]
----
<aop:pointcut id="idempotentOperation"
expression="execution(* com.xyz.service.*.*(..)) and
@annotation(com.xyz.service.Idempotent)"/>
