This commit reverts the changes made to WebDataBinder's doBind()
implementation in e4d03f6625 and instead implements the skipping logic
directly in checkFieldDefaults(), checkFieldMarkers(), and
adaptEmptyArrayIndices() by preemptively checking if the corresponding
field is allowed.
This commit also improves the Javadoc and adds missing tests.
Fixes gh-36625
HttpMethod.valueOf() performs a case-sensitive lookup of predefined
HttpMethod constants. For example, valueOf("GET") resolves to
HttpMethod.GET, whereas valueOf("get") results in a newly created
HttpMethod instance.
Update the Javadoc to explicitly document this behavior.
See gh-36642

This commit moves the JSON specific code to
KotlinSerializationJsonDecoder, uses switchOnFirst operator to keep the
existing behavior and derives the list serializer from the element one.
Closes gh-36597
Prior to this commit, the implementation of HttpMethod.valueOf()
aligned with the semantics of Enum#valueOf() which requires an exact
match for the enum constant name.
However, since HttpMethod is no longer an enum, that restriction is no
longer necessary. Consequently, this commit revises the implementation
of valueOf() to perform a case-insensitive lookup for predefined
constants.
In other words, HttpMethod.valueOf("GET") and HttpMethod.valueOf("get")
now both resolve to HttpMethod.GET.
Closes gh-36518
Prior to this commit, fields that are not allowed for binding were
always skipped and would not be bound. But the field and default marker
support (with the "_" and "!" prefixes) would be still considered and
could trigger collection instantiation/autogrow.
While this does not cause unwanted binding, this allocates memory for no
reason. This commit revisits the binding algorithm to only consider
default and field marker support if the regular field is allowed.
Fixes gh-36625
Use `CollectionUtils::newLinkedHashSet` instead of `LinkedHashSet::new` to avoid resizing.

Prior to this commit, all `with**Converter` methods in
`HttpMessageConverters` builders would only apply if the
`registerDefaults()` option is on. While the original intent is to allow
overrides for auto-detected defaults, this creates an unnecessary
discrepancy with `addCustomConverter` which is always effective.
Allowing sich registrations when defaults are off should not introduce
invalid states and only reflects the intent of the developer. This
commit now allows such cases.

`RestTemplate` is deprecated, this commit amends the JavaDoc to mention
its scheduled removal for the next major version, Spring Framework 8.0.
See gh-36574
As announced in "the state of HTTP clients in Spring" blog post
(https://spring.io/blog/2025/09/30/the-state-of-http-clients-in-spring),
the deprecation timeline for `RestTemplate` was announced last November
and docs were updated accordingly.
This commit `@Deprecate` `RestTemplate` and related types for removal to
send a stronger signal to our community.
The actual removal is scheduled for Spring Framework 8.0 (not yet
scheduled).
Closes gh-36574
Now that `RestClient` offers a better alternative, this commit revisits
our integration tests to use `RestClient` instead of `RestTemplate`.
Closes gh-36573
This commit adds integration tests and reference documentation
for multipart support in `RestClient` and `RestTestClient`.
Closes gh-35569
Closes gh-33263
Prior to this commit, the `FormHttpMessageConverter` would only support
`MultiValueMap` payloads for reading and writing. While this can be
useful when web forms contain multiple values under the same key, this
prevent developers from using a common `Map` type and factory methods
like `Map.of(...)`.
This commit relaxes constraints in `FormHttpMessageConverter` and
ensures that `Map` types are supported for reading and writing URL
encoded forms.
Note that when reading forms to a `Map`, only the first value for each
key will be considered and other values will be dropped if they exist.
Closes gh-36408
Prior to this commit, gh-36255 introduced the new
`MultipartHttpMessageConverter`, focusing on multipart message
conversion in a separate converter. The `FormHttpMessageConverter` did
conflate URL encoded forms and multipart messages in the same converter.
With the introduction of the new converter and related types in the same
package (with `Part`, `FormFieldPart` and `FilePart`), we can now
revisit this arrangement.
This commit restricts the `FormHttpMessageConverter` to URL encoded
forms only and as a result, changes its implementation to only consider
`MultiValueMap<String, String>` types for reading and writing HTTP
messages. Because type erasure, this converter is now a
`SmartHttpMessageConverter` to get better type information with
`ResolvableType`.
As a result, the `AllEncompassingFormHttpMessageConverter` is formally
deprecated and replaced by the `MultipartHttpMessageConverter`, by
setting part converters explicitly in its constructor.
Closes gh-36256
Prior to this commit, the `FormHttpMessageConverter` would write, but
not read, multipart HTTP messages. Reading multipart messages is
typicaly performed by Servlet containers with Spring's
`MultipartResolver` infrastructure.
This commit introduces a new `MultipartHttpMessageConverter` that copies
the existing feature for writing multipart messages, borrowed from
`FormHttpMessageConverter`. This also introduces a new `MultipartParser`
class that is an imperative port of the reactive variant, but keeping it
based on the `DataBuffer` abstraction. This will allow us to maintain
both side by side more easily.
This change also adds new `Part`, `FilePart` and `FormFieldPart` types
that will be used when converting multipart messages to
`MultiValueMap<String, Part>` maps.
Closes gh-36255
