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).

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.

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.

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.

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

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.
Issue: SPR-14773
Before this change the getHttpEntityType method in
HttpEntityMethodProcessor raised an ISE if the generic type cannot be
detected. That made sense for resolving a controller method argument
where the target body type is crucial. However for a return value
the generic type should not be required since we either have an
actual body or no body at all in which case it doesn't even matter.
This change relaxes the checks and defaults to Object.class for the
ResponseEntity generic type on the return value side.
Issue: SPR-14799
Prior to this commit, `ResourceTransformer` implementations would
resolve internal links to other resources: both relative and absolute
request paths.
For relative request paths, those transformers would call
`ResourceTransformerSupport.resolveUrlPath` with the resource path,
as provided in the original file. This can cause problems when a
`CachingResourceResolver` is configured in the resolver chain, because
this resolver is caching resources, deriving the cache key from the
given resource path — this can cause collisions for cases like this:
resources/
|--foo/
| |--foo.css (imports style.css)
| |--style.css
|--bar/
| |--bar.css (imports style.css)
| |--style.css
The first "style.css" resolved resource is then cached and will be given
to any request asking for "style.css".
To avoid those issues, this commit improves the `ResourceTransformer`
implementations to calculate the absolute request path before asking the
chain to resolve the resource URL, thus avoiding duplications.
The resource chain will be then asked to resolve "/foo/style/css" or
"/bar/style.css".
Issue: SPR-14597
Prior to this commit, the `HttpEntityMethodProcessor` would avoid
writing ETag/Last-Modified response headers before calling
`ServletWebRequest` to process conditional requests. This was done to
avoid duplicate response header values due to headers being already
written to the underlying servlet response.
This is still necessary for GET/HEAD requests, since this is properly
handled by `ServletWebRequest` for those cases. But
`HttpEntityMethodProcessor` should not make that decision for
PUT/PATCH/POST responses since developers are adding response headers on
purpose and should be in control of the situation — whereas
`ServletWebRequest` does not write those headers in those cases.
Issue: SPR-14767
This commit overrides the `checkResource` implementation in
`ScriptTemplateView` in order to check if the template file resource is
available and if the resolver can then proceed with rendering the
template.
Issue: SPR-14729
Cherry-picked from: 66b370e10
In order to simplify configuration for use cases involving @Bean where
only a bean name or aliases are supplied as an attribute, this commit
introduces a new 'value' attribute that is an @AliasFor 'name' in @Bean.
Issue: SPR-14728
Since appcache manifests can have various file extensions, developers
should register the (file extension, media type) mapping in their Spring
MVC / Reactive Web configuration.
This commit adds javadoc on both `AppCacheManifestTransformer` variants
to explain how to do that.
Issue: SPR-14510
Rather than setting the status to 503 directly from the timeout
interceptor which no longer seems to work reliably with Servlet
containers like Jetty even performing an additional ERROR dispatch back
to the original URL, we know rather set the DeferredResult to an
AsyncTimeoutException, which results in a dispatch and standard
handling within Spring MVC. This should be a more reliable way of
dealing with timeouts.
