Since an annotation cannot be extended in Java, there is no need to use
the INHERITED_ANNOTATIONS SearchStrategy to search for meta-annotations
on an annotation.
Prior to this commit, there was an issue with the semantics of property
source overrides. Specifically, a @PropertySource annotation present as
a meta-annotation on a @Configuration class was registered with higher
precedence than a @PropertySource annotation declared closer to (or
directly on) the @Configuration class. Consequently, there was no way
for a "local" @PropertySource annotation to override properties
registered via @PropertySource as a meta-annotation.
This commit addresses this issue by introducing a new overloaded
getMergedRepeatableAnnotationAttributes() variant in
AnnotatedTypeMetadata that allows the caller to supply a
sortByReversedMetaDistance flag. When set to `true`, the annotation
search results will be sorted in reversed order based on each
annotation's meta distance, which effectively orders meta-annotations
before annotations that are declared directly on the underlying element.
ConfigurationClassParser and AnnotationConfigUtils have been updated to
use this new repeatable annotation search method for @PropertySource.
Closes gh-31074
Reuses ValidationAnnotationUtils which is slightly optimized for the detection of Spring's Validated annotation now, also to the benefit of common web scenarios.
Closes gh-21852
Includes query(Class) method with value and property mapping support on JdbcClient.
JdbcClient's singleColumn/singleValue are declared without a Class parameter now.

AnnotatedTypeMetadata has various methods for finding annotations;
however, prior to this commit it did not provide explicit support for
repeatable annotations.
Although it is possible to craft a search "query" for repeatable
annotations using the MergedAnnotations API via getAnnotations(), that
requires intimate knowledge of the MergedAnnotations API as well as the
structure of repeatable annotations.
Furthermore, the bugs reported in gh-30941 result from the fact that
AnnotationConfigUtils attempts to use the existing functionality in
AnnotatedTypeMetadata to find repeatable annotations without success.
This commit introduces a getMergedRepeatableAnnotationAttributes()
method in AnnotatedTypeMetadata that provides dedicated support for
finding merged repeatable annotation attributes with full @AliasFor
semantics.
Closes gh-31041
The Javadoc for getAnnotationAttributes() states that it supports
"attribute overrides on composed annotations"; however, it actually
supports @AliasFor in general, including attribute aliases within a
given annotation.
This commit updates the Javadoc and corresponding tests to reflect that.
Closes gh-31042
Java 12 introduced java.lang.Class#componentType() as a shortcut for
getComponentType().
Since we started using arrayType() in fe5560400c, this commit switches
to componentType() for consistent API usage style.
Prior to this commit, the ignoreResourceNotFound flag in
@PropertySource was ignored by PropertySourceProcessor if a
PropertySourceFactory threw an exception which wrapped an exception
that would otherwise be ignored -- for example, a FileNotFoundException.
To address this issue, this commit updates PropertySourceFactory so
that it catches RuntimeException and IOException and then checks if the
exception or its cause is an "ignorable" exception in terms of
ignoreResourceNotFound semantics.
Closes gh-22276
Where possible, switch to the Long.parseLong variant that accepts a
start and end index for the supplied CharSequence, thus avoiding making
unnecessary copies of the String input.
Closes gh-30710
In order to reduce the surface area of published APIs in the affected
classes, this commit:
- Reverts the changes made to GeneratedClasses in c354b1014d.
- Reverts the changes made to DefaultGenerationContext in a28ec3a0a8.
- Makes the DefaultGenerationContext(DefaultGenerationContext, String)
constructor protected.
- Reworks the internals of TestContextGenerationContext to align with
the above changes.
See gh-30861
Closes gh-30895
Closes gh-30897
Aligned with shortcut handling in AutowiredAnnotationBeanPostProcessor.
Includes minor MethodInvoker optimization for pre-resolved targetClass.
Closes gh-30883
Prior to this commit, there was no explicit support for arrays,
collections, and maps in nullSafeConciseToString(). This lead to string
representations such as the following, regardless of whether the array,
collection, or map was empty.
- char[]@1623b78d
- java.util.ImmutableCollections$List12@74fe5c40
- java.util.ImmutableCollections$MapN@10e31a9a
This commit introduces explicit support for arrays, collections, and
maps in nullSafeConciseToString(), which results in the following
empty/non-empty string representations.
- array: {} / {...}
- collection: [] / [...]
- map: {} / {...}
The reason a string representation of an array uses "{}" instead of
"[]" (like in Arrays.toString(...)) is that
ObjectUtils.nullSafeToString(<array>) already follows that convention,
and the implementation of nullSafeConciseToString() aligns with that
for the sake of consistency.
Closes gh-30810
This commit extends the list of explicitly supported types in
ObjectUtils.nullSafeConciseToString() with the following.
- Optional
- File
- Path
- InetAddress
- Charset
- Currency
- TimeZone
- ZoneId
- Pattern
Closes gh-30805
ResolvableTypes are only considered equal if of the very same class now.
As a consequence, a forRawClass result is not equal to forClass anymore.
The new equalsType method is available for plain type equality checks.
Closes gh-28608
Closes gh-27748
As a consequence, the spring-messaging HandlerMethod detects interface parameter annotations as well, and the same is available for other HandlerMethod variants.
Closes gh-30801
This commit adds support for WildcardType bounds resolution,
commonly seen in Kotlin due to declaration-site variance,
but also possible in Java even if less common.
Closes gh-22313
This commit adds support for Kotlin parameter default values
in handler methods. It allows to write:
@RequestParam value: String = "default"
as an alternative to:
@RequestParam(defaultValue = "default") value: String
Both Spring MVC and WebFlux are supported, including on
suspending functions.
