This commit leverages a subset of @philwebb initial experimentation
to compute at build time the value of specific boolean static fields
in native images. This enhancement is implemented for now as a
GraalVM feature.
The goal here is to keep an optimized footprint via build time code
removal without leveraging build-time class initialization which is known
for the blocking compatibility issues it introduces due to its viral nature.
For now, the static fields initialized at build time with native are:
- NativeDetector#imageCode
- Fields with a name ending by "Present" in "org.springframework" package
typically used for classpath check with ClassUtils#isPresent
Closes gh-28624
ProblemDetail is intended to be extended with additional fields. This
commit removes its "with" methods for chained initialization to keep
it as plain as possible and avoid imposing a particular style on
subclasses.
See gh-27052
Includes deprecation of NestedServletException, whereas NestedCheckedException and NestedRuntimeException remain as base classes with several convenience methods.
Closes gh-25162
Update test detecting RouterFunction beans in parent contexts to use
different bean names and avoid shadowing. Changed the fix accordingly
given that BeanProvider does detect beans in parent contexts.
See gh-28595
At present, the customization of the default locale and timezone
resolution in CookieLocaleResolver and SessionLocaleResolver requires
subclassing them and overriding determineDefaultLocale and/or
determineDefaultTimeZone methods.
This commit simplifies resolution of the default locale and timezone
resolution by introducing dedicated functions for these purposes, thus
allowing customization without needing to resort to subclassing the
locale resolvers.
Closes gh-27609
This commit updates LocaleContextResolver to implement LocaleResolver
using default methods, which simplifies AbstractLocaleContextResolver
and aligns it more closely with AbstractLocaleResolver.
See gh-27609
This commit updates AcceptHeaderLocaleResolver to extend
AbstractLocaleResolver, which allows the removal of defaultLocale
managing code in AcceptHeaderLocaleResolver.
See gh-27609
Decoding is required for non-UrlResource when the HandlerMapping is
not expected to decode the path. Encoding is the opposite.
This commit ensures correct determination of whether the HandlerMapping
is expected to have decoded the path or not that in turn depends on
whether PathPattern or PathMatcher is in use.
Closes gh-27791
A static nested class does not keep an implicit reference to its
enclosing instance.
This prevents a common cause of memory leaks and uses less memory per
instance of the class.
Closes gh-28433
This commit introduces explicit HEAD support in Spring
MVC's ResourceHttpRequestHandler and WebFlux's ResourceWebHandler,
adding just headers but no body.
Closes gh-28291
This commit contains changes made because of the introduction of
HttpStatusCode. In general, methods that used to return a HttpStatus
now return HttpStatusCode instead, and methods that returned raw status
codes are now deprecated.
See gh-28214
Since the Nashorn JavaScript engine was removed in Java 15, these tests
will never be run on a Java 17+ JDK which is required as of Spring
Framework 6.0.
See gh-27919
DefaultHandlerExceptionResolver now supports ErrorResponse exceptions
and can map them to HTTP status and headers of the response. This
includes not only exceptions from spring-web, but also any other
exception that implements ErrorResponse.
ResponseEntityExceptionHandler is updated along the same lines, now
also handling any ErrorResponseException. It can be used it for
RFC 7807 support for Spring MVC's own exceptions.
See gh-27052
All Spring MVC exceptions from spring-web, now implement ErrorResponse
and expose HTTP error response information, including an RFC 7807 body.
See gh-27052
ErrorResponse represents a complete error response with status, headers,
and an RFC 7807 ProblemDetail body.
ErrorResponseException implements ErrorResponse and is usable on its
own or as a base class. ResponseStatusException extends
ErrorResponseException and now also supports RFC 7807 and so does its
sub-hierarchy.
ErrorResponse can be returned from `@ExceptionHandler` methods and is
mapped to ResponseEntity.
See gh-27052
ProblemDetail is a representation of an RFC 7807 "problem", and this
commits adds support for it in Spring MVC and WebFlux as a return value
from `@ExceptionHandler` methods, optionally wrapped with
ResponseEntity for headers.
See gh-27052
Although this commit only applies to test classes, it serves to reduce
the noise when searching for undesirable usage of StringBuffer in
production code.
This commit also applies additional clean-up tasks such as the following.
- final fields
- diamond operator (<>) for anonymous inner classes
- try with resources
- multi-catch
This has only been applied to `src/main/java`.
In order to catch Javadoc errors in the build, we now enable the
`Xwerror` flag for the `javadoc` tool. In addition, we now use
`Xdoclint:syntax` instead of `Xdoclint:none` in order to validate
syntax within our Javadoc.
This commit fixes all resulting Javadoc errors and warnings.
This commit also upgrades to Undertow 2.2.12.Final and fixes the
artifact names for exclusions for the Servlet and annotations APIs.
The incorrect exclusion of the Servlet API resulted in the Servlet API
being on the classpath twice for the javadoc task, which resulted in the
following warnings in previous builds.
javadoc: warning - Multiple sources of package comments found for package "javax.servlet"
javadoc: warning - Multiple sources of package comments found for package "javax.servlet.http"
javadoc: warning - Multiple sources of package comments found for package "javax.servlet.descriptor"
javadoc: warning - Multiple sources of package comments found for package "javax.servlet.annotation"
