This commit introduces support for tracking operations during SpEL
expression evaluation. If the maximum number of operations is exceeded,
a SpelEvaluationException is thrown.
The limit can be configured either on a per-use-case basis via
SpelParserConfiguration supplied to the SpelExpressionParser or
globally as a JVM system property or Spring property named
`spring.expression.maxOperations`.
Closes gh-36801
This commit fixes SpEL related tests that failed if the test methods
were executed in a different order than in the Gradle build.
(cherry picked from commit 97e10a5948)
- Avoid the use of assertThat(Arrays.equals(...))
- Convert assertThat(Boolean.FALSE).isEqualTo(x) to assertThat(x).isEqualTo(Boolean.FALSE)
- Convert assertThat(Boolean.TRUE).isEqualTo(x) to assertThat(x).isEqualTo(Boolean.TRUE)
- Convert assertThat(x.equals(y)).isTrue() to assertThat(x).isEqualTo(y)
- Convert assertThat(x.equals(y)).isFalse() to assertThat(x).isNotEqualTo(y)
- Remove unnecessary parentheses in assertThat() arguments
- Convert assertThat(x instanceof X).isFalse() to assertThat(x).isNotInstanceOf()
- Convert assertThat(x instanceof X).isTrue() to assertThat(x).isInstanceOf()
- Convert assertThat(!x).isTrue() to assertThat(x).isFalse()
- Inline conditions in assertThat() statements

Although this commit also changes the visibility of some test methods
to package-private, the remainder of that task will be addressed in
conjunction with gh-36496.

Since the Spring Framework uses American English spelling, this commit
updates Javadoc and the reference manual to ensure consistency in that
regard. However, there are two exceptions to this rule that arise due
to their use within a technical context.
- We use "cancelled/cancelling" instead of "canceled/canceling" in
numerous places (including error messages).
- We use "implementor" instead of "implementer".
Closes gh-36470

This commit removes the BDDMockito Checkstyle rule, since it did not
actually enforce the use of BDDMockito.
This commit also updates static imports to use Mockito instead of
BDDMockito where appropriate (automated via the Eclipse IDE Organize
Imports clean-up task).

Prior to this commit, if an appropriate Converter was registered with
the ConversionService that converts from a POJO to an array and that
ConversionService was registered with the Spring Expression Language
(SpEL) TypeConverter, an attempt to invoke a varargs method in a SpEL
expression with such a POJO would fail because the ConversionService
was not used to convert the POJO to an array suitable for the varargs
method invocation.
This commit revises the implementations of convertArguments(...) and
convertAllMethodHandleArguments(...) in ReflectionHelper to support
such use cases.
Closes gh-34371
Prior to this commit, if a MethodHandle was registered as a custom
function in the Spring Expression Language (SpEL) for a static method
that accepted only a variable argument list (for example,
`static String func(String... args)`), attempting to invoke the
registered function within a SpEL expression resulted in a
ClassCastException because the varargs array was unnecessarily wrapped
in an Object[].
This commit modifies the logic in FunctionReference's internal
executeFunctionViaMethodHandle() method to address that.
Closes gh-34109
Prior to this commit, the SpEL Tokenizer threw an IllegalStateException
when an unsupported character was detected in a SpEL expression;
however, the Javadoc for ExpressionParser.parseExpression() states that
it throws a ParseException if an exception occurred during parsing.
This commit addresses that issue by throwing a SpelParseException for
an unsupported character in a SpEL expression, using a new
UNSUPPORTED_CHARACTER enum constant in SpelMessage.
Closes gh-33767
Prior to this commit, when invoking init methods and destroy methods
for beans as well as methods within Spring Expression Language (SpEL)
expressions via reflection, we invoked them based on the "interface
method" returned from ClassUtils.getInterfaceMethodIfPossible(). That
works well for finding methods defined in an interface, but it does not
find public methods defined in a public superclass.
For example, in a SpEL expression it was previously impossible to
invoke toString() on a non-public type from a different module. This
could be seen when attempting to invoke toString() on an unmodifiable
list created by Collections.unmodifiableList(...). Doing so resulted in
an InaccessibleObjectException.
Although users can address that by adding an appropriate --add-opens
declaration, such as --add-opens java.base/java.util=ALL-UNNAMED, it is
better if applications do not have to add an --add-opens declaration
for such use cases in SpEL. The same applies to init methods and
destroy methods for beans.
This commit therefore introduces a new
getPubliclyAccessibleMethodIfPossible() method in ClassUtils which
serves as a replacement for getInterfaceMethodIfPossible().
This new method finds the first publicly accessible method in the
supplied method's type hierarchy that has a method signature equivalent
to the supplied method. If the supplied method is public and declared
in a public type, the supplied method will be returned. Otherwise, this
method recursively searches the class hierarchy and implemented
interfaces for an equivalent method that is public and declared in a
public type. If a publicly accessible equivalent method cannot be
found, the supplied method will be returned, indicating that no such
equivalent method exists.
All usage of getInterfaceMethodIfPossible() has been replaced with
getPubliclyAccessibleMethodIfPossible() in spring-beans and
spring-expression. In addition, getInterfaceMethodIfPossible() has been
marked as deprecated in favor of the new method.
As a bonus, the introduction of getPubliclyAccessibleMethodIfPossible()
allows us to delete a fair amount of obsolete code within the SpEL
infrastructure.
