This commit makes sure that no `StringIndexOutOfBoundsException` is
thrown when `getForRequestUrl` is called with a URL that's shorter than
the expected context path.
Issue: SPR-16526
From #9a894a we began using the content-type from the ResponseEntity
but cross-checking it still against the requested content type.
Arguably there isn't any purpose in cross-checking. The only possible
outcomes are: a) it's compatible or b) it's not, which would result in
406 (NOT_ACCEPTABLE). As we've been given explicitly the media type to
use, it makes little sense to send 406, ignoring the wish to use that
content type.
Issue: SPR-16251
Access-Control-Allow-Credentials CORS header, used to
allow cookies with CORS requests, is not set to true
anymore by default when enabling CORS with
@CrossOrigin or global CORS configuration in order to
provide a more secured default CORS configuration.
The related allowCredentials property now requires to
be set to true explicitly in order to support cookies
with CORS requests.
Issue: SPR-16130
MockMvc now properly detects the presence of an AsyncContext and
re-uses the response instance used to start it.
This commit also includes a minor fix in
ResponseBodyEmitterReturnValueHandler to ensure it does not disable
ETag related content buffering for reactive return values that do not
result in streaming (e.g. single value or collections).
Issue: SPR-16067
Prior to this commit, the Resource `HandlerMapping` configured by
`@EnableSpringMvc` would be set up with only one custom
`HandlerInterceptor` (the one exposing the `ResourceUrlProvider` for
resolving URLs of static resources).
This behavior is not consistent with the rest of the default
configuration which leverages the interceptors configured against the
interceptor registry (with possible user-provided ones).
This change allows to register interceptors against resource handling;
this can be useful for metrics purposes, as in
spring-projects/spring-boot#10335.
Issue: SPR-16034
The Javadoc on tag classes now has all the information including a
list of all tags at the package level, HTML tables listing tag
attributes in each tag class, and class level description that is
as good or in many cases better than what was in the reference.
Issue: SPR-16045
Includes unified detection of Kotlin's optional parameters in MethodParameter.isOptional(), reduces BeanUtils.findPrimaryConstructor to Kotlin semantics (for reuse in AutowiredAnnotationBeanPostProcessor), and finally introduces a common KotlinDetector delegate with an isKotlinType(Class) check.
Issue: SPR-15877
Issue: SPR-16020
This commit introduces the following changes.
1) It adds a new Spring @NonNull annotation which allows to apply
@NonNullApi semantic on a specific element, like @Nullable does.
Combined with @Nullable, it allows partial null-safety support when
package granularity is too broad.
2) @Nullable and @NonNull can apply to ElementType.TYPE_USE in order
to be used on generic type arguments (SPR-15942).
3) Annotations does not apply to ElementType.TYPE_PARAMETER anymore
since it is not supported yet (applicability for such use case is
controversial and need to be discussed).
4) @NonNullApi does not apply to ElementType.FIELD anymore since in a
lot of use cases (private, protected) it is not part for the public API
+ its usage should remain opt-in. A dedicated @NonNullFields annotation
has been added in order to set fields default to non-nullable.
5) Updated Javadoc and reference documentation.
Issue: SPR-15756
Prior to this commit, HTTP Range requests were only supported by the
ResourceHttpRequestHandler when serving static resources.
This commit improves the `HttpEntityMethodProcessor` and
the `RequestResponseBodyMethodProcessor`. They now extract
`ResourceRegion`s from the `Resource` instance returned by the
Controller and let the Resource-related message converters
handle the writing of the resource (including partial writes).
Controller methods can now handle Range requests for
return types that extend Resource or HttpEntity:
@RequestMapping("/example/video.mp4")
public Resource handler() { }
@RequestMapping("/example/video.mp4")
public HttpEntity<Resource> handler() { }
Issue: SPR-15789, SPR-13834
Includes general streamlining of dependency declarations with reduced version variables, direct use of EclipseLink 2.7 and its implicit JPA 2.2 dependency in spring-orm, mixed use of Hibernate 5.2.10 and 5.1.10 for integration tests, as well as an upgrade to Jetty 9.4.7 RC0 and a downgrade to Groovy 2.4.12 (since Groovy 2.5 won't be final in time for Spring Framework 5.0).
Issue: SPR-15879
Issue: SPR-15880
StandardMultipartHttpServletRequest now properly decodes RFC-5987
encoded filenames (i.e. filename*) by delegating to ContentDisposition
and also support RFC-2047 syntax through javax.mail MimeUtility.
Issue: SPR-15205
This commit updates BeanUtils class in order to add Kotlin optional
parameters with default values support to the immutable data classes
support introduced by SPR-15199.
Issue: SPR-15673
This commit ensure that null-safety is consistent between
getters and setters in order to be able to provide beans
with properties with a common type when type safety is
taken in account like with Kotlin.
It also add a few missing property level @Nullable
annotations.
Issue: SPR-15792
ContentNegotiationManagerFactoryBean now provides an option to
explicitly set the strategies to use vs customizing a fixed
list of default strategies.
Issue: SPR-11114
This commits extends nullability declarations to the field level, formalizing the interaction between methods and their underlying fields and therefore avoiding any nullability mismatch.
Issue: SPR-15720
Supporting ScriptEngine#eval(String, Bindings) when no render function
is specified allows to support use cases where script templates are
simply evaluating a script expression with an even more simplified
configuration.
This improvement also makes it possible to use script engines that
do not implement Invocable.
Issue: SPR-15115
This commit also removes nullability from two common spots: ResolvableType.getType() and TargetSource.getTarget(), both of which are never effectively null with any regular implementation. For such scenarios, a non-null empty type/target is the cleaner contract.
Issue: SPR-15540
Beyond just formally declaring the current behavior, this revision actually enforces non-null behavior in selected signatures now, not tolerating null values anymore when not explicitly documented. It also changes some utility methods with historic null-in/null-out tolerance towards enforced non-null return values, making them a proper citizen in non-null assignments.
Some issues are left as to-do: in particular a thorough revision of spring-test, and a few tests with unclear failures (ignored as "TODO: NULLABLE") to be sorted out in a follow-up commit.
Issue: SPR-15540
With the new `ParsingPathMatcher` implementation, new patterns are now
allowed, such as `"/foo/{*bar}". The `"{*bar}"` segment will capture
everything until the end of the given path. Adding other elements after
that segment is illegal and will throw exceptions.
One can configure on a `PathMatchConfigurer` various options like
`useTrailingSlashMatch` and `useSuffixPatternMatch`; those options, when
enabled, will try to append suffixes like `".*"` and `"/"` to existing
path patterns. In case of a "capture the rest" pattern segment, those
options won't be honored.
This is why this commit ensures that an exception is thrown at the start
of the application if an illegal configuration is applied to the
`PathMatchConfigurer`.
Issue: SPR-15303, SPR-15558
This commit introduces 2 new @Nullable and @NonNullApi
annotations that leverage JSR 305 (dormant but available via
Findbugs jsr305 dependency and already used by libraries
like OkHttp) meta-annotations to specify explicitly
null-safety of Spring Framework parameters and return values.
In order to avoid adding too much annotations, the
default is set at package level with @NonNullApi and
@Nullable annotations are added when needed at parameter or
return value level. These annotations are intended to be used
on Spring Framework itself but also by other Spring projects.
@Nullable annotations have been introduced based on Javadoc
and search of patterns like "return null;". It is expected that
nullability of Spring Framework API will be polished with
complementary commits.
In practice, this will make the whole Spring Framework API
null-safe for Kotlin projects (when KT-10942 will be fixed)
since Kotlin will be able to leverage these annotations to
know if a parameter or a return value is nullable or not. But
this is also useful for Java developers as well since IntelliJ
IDEA, for example, also understands these annotations to
generate warnings when unsafe nullable usages are detected.
Issue: SPR-15540
Prior to this commit, resolving resources from webjars using the
`WebJarAssetLocator.getFullPath` could lead to multiple candidates,
since this method is trying to find *any* resource matching that path
under the given webjar location.
This commit replaces that call with
`WebJarAssetLocator.getFullPathExact`, which avoids those multiple
matches and only resolves resources if the given path is exact.
Issue: SPR-15526
(cherry picked from commit e2aa117ff9)
Prior to this commit, the AbstractFlashMapManager has used the
originating URI but the query string of the forwarded request. That
resulted to FlashMap not being matched even when both originating
URI and query string matched the FlashMap attributes. The originating
query string is now used to match the forwarded request.
Issue: SPR-15505
HttpMessageConverter's are client and server and arguably shouldn't
contain a server-side concept such a response status.
The status field is recent, it was added to differentiate 400 vs 500
errors with Jackson 2.9+ but there is no need for it since the same
distinction is reflected in raising an HttpMessageNotReadableException
vs a general HttpMessageConversionException.
Issue: SPR-15516
Spring MVC now treats Flux<String> + "application/json" as (serialized)
text to be written directly to the response as is. This is consistent
with the rendering of String + "application/json".
Issue: SPR-15456
InvalidDefinitionException has been introduced in Jackson 2.9 to be
able to differentiate invalid data sent from the client (should still
generate a 4xx HTTP status code) from server side errors like beans with
no default constructor (should generate a 5xx HTTP status code).
Issue: SPR-14925
This commit adds support for reactive library types to be returned
directly from controller methods adapting them either to a
ResponseBodyEmitter (streaming) or DeferredResult (non-streaming).
The reactive libraries supported are the ones that can adapted to a
Reactive Streams Publisher through the ReactiveAdapterRegistry.
Issue: SPR-15365
Revise Javadoc on AsyncHandlerMethodReturnValueHandler to clarify its
main purpose is to prioritze custom async return value handlers ahead
of built-in ones. Also replace the interface from built-in handlers
which are prioritized already.
Remove DeferredResultAdapter and ResponseBodyEmitterAdapter --
introduced in 4.3 for custom async return value handling, since for
5.0 we will add built-in support for reactive types and the value of
these contracts becomes very marginal.
Issue: SPR-15365
This commit changes `ResourceTransformerSupport` to look for the
`ResourceUrlProvider` in the current request if none is configured on
the resource transformer itself.
Issue: SPR-15369
Prior to this commit, the `VersionResourceResolver` implementations of
`resolveUrlPathInternal` would delegate to the resolver chain but would
never use the give result if the current request didn't match a
configured version strategy pattern.
This is a problem if the resolver supposed to resolve the resource path
is configured after a `VersionResourceResolver` in the resolver chain;
this means that other resolver never gets to participate in the result
of the chain.
Issue: SPR-15372
Includes a new overloaded ModelAndView constructor with an HttpStatus argument, as well as a HandlerMethodArgumentResolverSupport refactoring (revised checkParameterType signature, actually implementing the HandlerMethodArgumentResolver interface).
Issue: SPR-15199
This commit introduces a `useRegisteredExtensionsOnly` property that
indicates whether classes that use the `MediaTypeFactory` for supplying
default media types can do so.
- In classes that were introduced in Spring 5.0, the
`useRegisteredExtensionsOnly` property takes the place of the
`useJaf` property that was removed in 0aaa652
- In classes that existed before Spring 5.0, the
`useRegisteredExtensionsOnly` property is added in addition to the
deprecated `useJaf`, the latter delegating to the former, but with
flipped behavior.
Issue: SPR-14908
This commit changes the `MockServletContext.getMimeType` method to use
`MediaTypeFactory` instead of JAF. It also adds a `addMimeType(String,
MediaType)` method to customize the mime types returned from said
method.
Issue: SPR-14908
This commit updates the main code base to conform to the dropped JAF
dependency in MediaTypeFactory. Specifically, it
- Removes JAF detection (JAF_PRESENT constants)
- Deprecated useJaf properties, with no direct replacement.
- Updated docs to remove JAF references, in favor of MediaTypeFactory.
Issue: SPR-14908
This commit introduces a PathPatternParser which parses request pattern
strings into PathPattern objects which can then be used to fast
match incoming string paths. The parser and matching supports the syntax
as described in SPR-14544. The code is optimized around the common usages
of request patterns and is designed to create very little transient
garbage when matching.
Issue: SPR-14544
Codacy warns us that there are several references to Boolean
constructors in the tests. Direct usage of the Boolean constructor is
discouraged and even deprecated in Java 9 [1]. Boolean constructor use
can easily be replaced with the constant instances.
This commit contains the following changes:
- replace references to Boolean constructors with boolean constants in
JSP tag tests
- update the copyright year where necessary
- BooleanComparatorTests is intentionally left unchanged as it should
also work with the non-constant instances correctly

Issue: SPR-15076
Kotlin JSR 223 support currently requires kotlin-script-util
dependency (jcabi-aether, maven-core and aether-api can be
excluded since they are only used for live import of
dependencies and bring a lot of JARs in the classpath) and a
/META-INF/services/javax.script.ScriptEngineFactory
file specifying the ScriptEngineFactory to use, in that case
org.jetbrains.kotlin.script.jsr223.KotlinJsr223JvmLocalScriptEngineFactory.
Issue: SPR-15059
ServerWebExchange now provides access to "requestParams" as a
MulitValueMap with query parameters and form data combined.
The combined map is then used for the params condition of
@RequestMapping purposes () and also for @RequestParam arguments.
Issue: SPR-15000
When getting the lookup path of a resource, both query params and hashes
should be removed from the request path.
This commit fixes the public path resolution for paths like
`/resources/main.svg#icon-hamburgermenu`.
Issue: SPR-14928
Prior to this commit, `@ExceptionHandler` methods could not be injected
with `RedirectAttributes` arguments. This would make it impossible to
handle an error by redirecting to another view and add flashmap
attributes, to be included in the model when the next view is called.
Here is an example:
```
@ExceptionHandler(MyException.class)
public String handleException(MyException ex, RedirectAttributes
redirectAttributes) {
redirectAttributes.addFlashAttribute("errorMessage",
"This is an error message");
return "redirect:/";
}
```
This commit adds a new `RedirectAttributesMethodArgumentResolver`
instance in the list of pre-configured `HandlerMethodArgumentResolver`
in `ExceptionHandlerExceptionResolver`.
Issue: SPR-14651
This commit polishes Kotlin nullable support by reusing
MethodParameter#isOptional() instead of adding a new
MethodParameter#isNullable() method, adds
Kotlin tests and introduces Spring Web Reactive
support.
Issue: SPR-14165
Where `isOptional` is used, also check for `isNullable` i.e.
values are not considered required if they are Kotlin nullables:
- spring-messaging: named value method arguments
- spring-web: named value method arguments
- spring-webmvc: request parts
This means that Kotlin client code no longer has to explicity specify
"required=false" for Kotlin nullables -- this information is inferred
automatically by the framework.
Issue: SPR-14165
In case the filter is also registered to the ERROR dispatcher, the
following happens:
* the filter is executed once for the regular execution
* the filter should be executed a second time when dispatched to error
Since the filter is a `OncePerRequestFilter`, the filter is only
executed once and won't be executed when handling the error.
This can lead to situations like spring-projects/spring-boot#7348
This commit makes this filter a simple `GenericFilterBean`.
Issue: SPR-14891
When resolved through the `GzipResourceResolver`, CSS files can be
resolved as their pre-gzipped variant, if a ".gz" file is present in the
configured resource locations.
Such resources are gzipped and thus should not be transformed by
`CssLinkResourceTransformer`s, since rewriting those would need to
uncompress/transform/recompress. This would lead to poorer performances
than resolving plain resources and delegating compression to the
container.
This commit checks for `GzippedResource` instances in
`CssLinkResourceTransformer` and avoids processing them.
