Updated the Spring Framework documentation to include an example of using Vavr's Try monad to trigger transaction rollbacks when a @Transactional-annotated method returns a Failure. The modified documentation demonstrates how to use Try in a transactional method and how to check if an exception has been wrapped inside a Try.Failure instance. Additionally, a link to the official Vavr documentation was added to provide more information on the Try method.
This commit adds a reflection hint for HttpMethod#valueOf in order
to be able to support conversion required for Spring Boot
configuration properties binding as described in
https://github.com/spring-projects/spring-boot/issues/34483.
Closes gh-30201
The `echoWebSocketHandler()` method is not defined in the
`WebSocketConfigurer` interface and should therefore be annotated with
`@Bean` instead of `@Override`.
Closes gh-30183
After setting up a JDK 20 CI build pipeline, numerous tests involving
date/time parsing and formatting began to fail [0]. (The failing JPA
tests are not specific to JDK 20.)
For example, we encounter visually confusing assertion failures such as
the following.
org.opentest4j.AssertionFailedError:
expected: "12:00 PM"
but was: "12:00 PM"
The expected string contains a normal space (which has always been the
case prior to JDK 20); whereas, the actual string now contains a narrow
non-breaking space.
The cause of this is mentioned in the JDK 20 Release Notes [1] as "NBSP
prefixed to a, instead of a normal space". Note, however, that the
links for the first two bullet points in that section are mixed up.
"NBSP prefixed to a, instead of a normal space" should point to [2].
Furthermore, the new whitespace character is not a non-breaking space
(NBSP) but rather a narrow non-breaking space (NNBSP). In addition, the
second bullet point should technically read "NNBSP prefixed to `a`,
instead of a normal space" -- even though `a` provides limited value to
most readers.
The downside for the Java community is that this constitutes a breaking
change for parsing and formatting date/time values that include "AM"
and "PM" units (any may potentially apply to other date/time
parsing/formatting scenarios). In Spring Framework's test suite we have
witnessed this in conjunction with Spring's @DateTimeFormat and
DateTimeFormatterFactory infrastructure as well as with Google's
Gson-to-JSON support.
A colleague who works at Oracle graciously informed me that one can use
"legacy locale data" by supplying `-Djava.locale.providers=COMPAT` as a
JVM argument, noting however that this option limits some newer
functionalities (but without enumerating which new functionalities one
might be missing when using this option).
In any case, this commit adds that JVM argument to our Gradle toolchain
builds so that our test suite passes on JDK 20, and we will continue to
investigate further options for our builds and for our users.
Note, however, that one must manually configure the
`-Djava.locale.providers=COMPAT` JVM argument when running affected
tests within an IDE.

Prior to this commit, the EntityManager was not closed in
SharedEntityManagerCreator.DeferredQueryInvocationHandler's
invoke(Object, Method, Object[]) method if an invocation of
getOutputParameterValue(*) threw an exception other than
IllegalArgumentException, which could lead to a connection leak.
This commit addresses this by catching RuntimeException instead of
IllegalArgumentException.
Closes gh-30161
This commit turns some stream-based iterations back into simpler
enhanced for loops.
For simple use cases like these, where the stream API is merely used to
map/filter + collect to a List, a for loop is more efficient.
This is especially true for small collections like the ones we deal
with in BodyInserters/BodyExtractors here (in the order of 50ns/op vs
5ns/op). These cases are also simple enough that they don't lose in
readability after the conversion.
Closes gh-30136
This commit ensures that the HttpMethod, exposed through
ServerHttpRequest::getMethod, is cached in AbstractServerHttpRequest so
that potentially expensive HTTP method lookups are only done once.
Closes gh-30139
Supplying a large regular expression to the `matches` operator in a
SpEL expression can result in errors that are not very helpful to the
user.
This commit improves the diagnostics in SpEL for the `matches` operator
by throwing a SpelEvaluationException with a meaningful error message
to better assist the user.
Closes gh-30144
Attempting to create repeated text in a SpEL expression using the
repeat operator can result in errors that are not very helpful to the
user.
This commit improves the diagnostics in SpEL for the repeat operator by
throwing a SpelEvaluationException with a meaningful error message in
order to better assist the user.
Closes gh-30142
Prior to this commit, the pattern cache for the SpEL `matches` operator
only applied to expressions such as the following where the same
`matches` operator is invoked multiple times with different input:
"map.keySet().?[#this matches '.+xyz']"
The pattern cache did not apply to expressions such as the following
where the same pattern ('.+xyz') is used in multiple `matches`
operations:
"foo matches '.+xyz' AND bar matches '.+xyz'"
This commit addresses this by moving the instance of the pattern cache
map from OperatorMatches to InternalSpelExpressionParser so that the
cache can be reused for all `matches` operations for the given parser.
Closes gh-30140
This commit adds a link to the now published information on spring.io
about the GPG key used to sign the Spring artifacts published on Maven
Central.
Closes gh-23434
This commit adds an `anchor-rewrite.properties` file in the reference
documentation sources. This allows to redirect from one anchor to
another when they are renamed.
This also populates the file with anchors that were renamed in the AOT
section of the documentation.
Closes gh-30132
Prior to this commit, the `RequestedContentTypeResolverBuilder` would
create a `RequestedContentTypeResolver` that internally delegates to a
list of resolvers. Each resolver would either return the list of
requested media types, or a singleton list with the "*/*" media type; in
this case this signals that the resolver cannot find a specific media
type requested and that we should continue with the next resolver in the
list.
Media Types returned by resolvers can contain parameters, such as the
quality factor. If the HTTP client requests "*/*;q=0.8", the
`HeaderContentTypeResolver` will return this as a singleton list. While
this has been resolved from the request, such a media type should not be
selected over other media types that could be returned by other
resolvers.
This commit changes the `RequestedContentTypeResolverBuilder` so that it
does not select "*/*;q=0.8" as the requested media type, but instead
continues delegating to other resolvers in the list. This means we need
to remove the quality factor before comparing it to the "*/*" for
equality check.
Fixes gh-29915
This commit ensures that methods declared in java.lang.Object (such as
toString() can be invoked on a JDK proxy instance in a SpEL expression.
