When using Appache Commons FileUpload, multi parts with binary data
(i.e. that are not actual files) are saved and then accessed as
String request parameters.
Before this change however the RequestPartServletServerHttpRequest
used a fixed encoding (UTF-8) while the parsing code in
CommonsFileUploadSupport/Resolver used the encoding from the
content-type header, or the request, or the FileUpload component.
This change does a best effort to determine the encoding of the
request parameter using a similar algorithm as the parsing side
that should work the same unless the encoding comes from the
FileUpload component which is not accessible.

This commit moves the check whether an HTTP method supports request
body up to the base class so that all sub-classes can benefit (not just
@RequestBody).
Issue: SPR-13176
Since the changes introduced in SPR-12778, some `@RequestBody` args
would not be properly processed in some cases:
* requests with an empty body
* no Content-Type header defined
This typically happens when GET requests are mapped on a handler dealing
with POST requests and HTTP bodies.
This change makes sure that the `RequestResponseBodyMethodProcessor` is
only involved for requests that:
* have a Content-Type defined
* OR are HTTP requests eligible for an HTTP body (PUT, POST, PATCH)

Fixesspring-projects/spring-boot#3313
This split avoids a package tangle (between core and core.annotation) and also allows for selective use of raw annotation exposure versus synthesized annotations, with the latter primarily applicable to web and message handler processing at this point.
Issue: SPR-13153
Prior to this commit, `HttpEntityMethodProcessor` would rely on
`ServletWebRequest` to process conditional requests and with incoming
`"If-Modified-Since"` / `"If-None-Match"` request headers.
This approach is problematic since in that class:
* response is wrapped in a `ServletServerHttpResponse`
* this wrapped response does not write response headers right away
* `ServletWebRequest.checkNotModified` methods can't apply their
logic with incomplete response headers
This solution adds some minimal code duplication and applies
the conditional request logic within the Processor.
A possible alternative would be to improve the
`ServletServerHttpResponse$ServletResponseHttpHeaders` implementation
with write methods - but this solution would only work for Servlet 3.x
applications.

This commit introduces the following changes:
- In AbstractMessageConverterMethodProcessor, the type aware variant of
canWrite() is now called when the converter implements
GenericHttpMessageConverter.
- The Javadoc has been updated in GenericHttpMessageConverter to make it clear
that the type aware canRead() and canWrite() methods should perform the same
checks than non type aware ones.
- AbstractGenericHttpMessageConverter now implements default type aware
canRead() and canWrite() methods than just call the non type aware variants.
Due to this, if subclasses just override the non type aware variants,
they still have the right behavior.
Issue: SPR-13161
This commit adds canWrite() and write() methods to the
GenericHttpMessageConverter interface. These are type aware variants
of the methods available in HttpMessageConverter, in order to keep
parametrized type information when serializing objects.
AbstractMessageConverterMethodProcessor now calls those type aware
methods when the message converter implements GenericHttpMessageConverter.
AbstractJackson2HttpMessageConverter and GsonHttpMessageConverter uses
these new methods to make @ResponseBody method return type available
for type resolution instead of just letting the JSON serializer trying
to guess the type to use from the object to serialize.
Issue: SPR-12811
This change fixes a NullPointerException in GzipResourceResolver, which
assumed that calls to the `resolveResource` method were made with only
non-null values for request.
This is not the case for the VersionResourceResolver, which tries to
resolve resources that aren't requested per se by the HTTP request.
Issue: SPR-13149
- Simplified "check" algorithms in CorsConfiguration
- Improved robustness of setter methods in CorsConfiguration in order to
avoid attempts to modify immutable lists
- Improved CORS documentation and fixed typo
- Introduced constants in CorsConfiguration
- Removed auto-boxing in CorsRegistration
Before this change ResponseStatusExceptionResolver always used
.sendError despite the javadoc on @ResponseStatus#code. This was
perhaps justifiable from a HandlerExceptionResolver. Nevertheless
.setStatus should be more REST API friendly while still marking
the response as an error.
Issue: SPR-11193
Before this change the AbstractMessageConverterMethodProcessor always
raised a 406 if it couldn't find a converter. However if the reason
for not finding it is because there is simply no converter for the
return value type (i.e. programming error) and doesn't have anything to
do with content negotiation, then we should raise a 500 instead and
make it easier to figure out what's wrong.
Issue: SPR-13135
This commit improves SPR-13090 and avoids adding duplicate ETag and
Last-Modified headers in HTTP responses.
Previously, those were added twice to the response since:
* we're adding all ResponseEntity headers to the response
* the `checkNotModified` methods automatically add those headers
Issue: SPR-13090
Before this change HandlerMethodReturnValueHandler's were invoked in a
specific order (type-based, annotation-based, custom). However handlers
that deal with asynchronous return value handling need to always be
considered first. This affects custom handlers in particular since they
are normally ordered last.
This change introduces an AsyncHandlerMethodReturnValueHandler
sub-interface with a single method to determine if the return value is
asynchronous and if it is to look for a matching handler only among
those that are of type AsyncHandlerMethodReturnValueHandler.
Issue: SPR-13083
This commit introduces the following changes in AbstractHandlerExceptionResolver:
- warnLogger used to log exception is enabled by default
- the exception message is now logged instead of the whole exception stacktrace
- warn logging is only performed if doResolveException() returns a non-null
ModelAndView, in order to avoid logging multiple times the error
Issue: SPR-13100
Before this change a missing path variable value resulted in a 400
error where in fact the error is due to a mismatch between the
declared @PathVariable and the URI template, i.e. a 500 error.
This change introduced a MissingPathVariableException as a sub-class
of ServletRequestBindingException (the exception previously thrown)
and results in a response status code of 500 by default.
Issue: SPR-13121
In AnnotatedElementUtils, all methods pertaining to merging annotation
attributes have been renamed to "getMerged*()" and "findMerged*()"
accordingly. Existing methods such as getAnnotationAttributes(..) have
been deprecated in favor of the more descriptive "merged" variants.
This aligns the naming conventions in AnnotatedElementUtils with those
already present in AnnotationReadingVisitorUtils.
The use of "annotationType" as a variable name for the fully qualified
class name of an annotation type has been replaced with
"annotationName" in order to improve the readability and intent of the
code base.
In MetaAnnotationUtils.AnnotationDescriptor, getMergedAnnotation() has
been renamed to synthesizeAnnotation(), and the method is now
overridden in UntypedAnnotationDescriptor to always throw an
UnsupportedOperationException in order to avoid potential run-time
ClassCastExceptions.
Issue: SPR-11511
Prior to this change, the `"Last-Modified"` and "`Etag`" support had
been improved with SPR-11324: HTTP response headers are now
automatically added for conditional requests and more.
This commit fixes the format of the "`Last-Modified`" and "`ETag`"
values, which were using an epoch timestamp rather than an HTTP-date
format defined in RFC 7231 section 7.1.1.1.
Also, Conditional responses are only applied when the given response
applies, i.e. when it has an compatible HTTP status (2xx).
Issue: SPR-13090
This commit introduces the following changes:
- configureCors(CorsConfigurer configurer) is renamed to
addCorsMappings(CorsRegistry registry)
- enableCors(String... pathPatterns) is renamed to
addMapping(String pathPattern)
- <cors /> element must have at least one <mapping /> child
element in order to be consistent with XML based configuration
and have more explicit configuration
Issues: SPR-12933, SPR-13046
This commit introduces support for this kind of CORS XML namespace configuration:
<mvc:cors>
<mvc:mapping path="/api/**"
allowed-origins="http://domain1.com, http://domain2.com"
allowed-methods="GET, PUT"
allowed-headers="header1, header2, header3"
exposed-headers="header1, header2" allow-credentials="false"
max-age="123" />
<mvc:mapping path="/resources/**" allowed-origins="http://domain1.com" />
</mvc:cors>
Issue: SPR-13046
Spring Framework 4.2 RC1 introduced support for synthesizing an
annotation from an existing annotation in order to provide additional
functionality above and beyond that provided by Java. Specifically,
such synthesized annotations provide support for @AliasFor semantics.
As luck would have it, the same principle can be used to synthesize an
annotation from any map of attributes, and in particular, from an
instance of AnnotationAttributes.
The following highlight the major changes in this commit toward
achieving this goal.
- Introduced AnnotationAttributeExtractor abstraction and refactored
SynthesizedAnnotationInvocationHandler to delegate to an
AnnotationAttributeExtractor.
- Extracted code from SynthesizedAnnotationInvocationHandler into new
AbstractAliasAwareAnnotationAttributeExtractor and
DefaultAnnotationAttributeExtractor implementation classes.
- Introduced MapAnnotationAttributeExtractor for synthesizing an
annotation that is backed by a map or AnnotationAttributes instance.
- Introduced a variant of synthesizeAnnotation() in AnnotationUtils
that accepts a map.
- Introduced findAnnotation(*) methods in AnnotatedElementUtils that
synthesize merged AnnotationAttributes back into an annotation of the
target type.
The following classes have been refactored to use the new support for
synthesizing AnnotationAttributes back into an annotation.
- ApplicationListenerMethodAdapter
- TestAnnotationUtils
- AbstractTestContextBootstrapper
- ActiveProfilesUtils
- ContextLoaderUtils
- DefaultActiveProfilesResolver
- DirtiesContextTestExecutionListener
- TestPropertySourceAttributes
- TestPropertySourceUtils
- TransactionalTestExecutionListener
- MetaAnnotationUtils
- MvcUriComponentsBuilder
- RequestMappingHandlerMapping
In addition, this commit also includes changes to ensure that arrays
returned by synthesized annotations are properly cloned first.
Issue: SPR-13067
Reinstate a variant of the `WebContentGenerator.checkAndPrepare` method
for projects that are using it.
This variant is now marked as deprecated.
Issue: SPR-11792
Prior to this commit, the `ResourceHttpRequestHandler` would not
properly handle HTTP requests to **directories contained in JARs**.
This would result in HTTP 500 errors, caused by `FileNotFoundException`
or `NullPointerException`.
This can be tracked to webapp ClassLoader implementations in servlet
containers:
* in Jetty9x, fetching a directory within a JAR as a `Resource` and
getting its InputStream work fine, but attempting to `close()` it
results in a NullPointerException as the underlying stream is null.
* In Tomcat6x, one cannot fetch an InputStream for the same `Resource`
as it throws a FileNotFoundException.
This change adds more try/catch clauses and catches more Exception so as
to result in HTTP 200 OK responses instead of server errors. While this
is inconsistent because the same code path would result in HTTP 404 with
existing directories on the file system, there's no other simple way to
make those checks for resources contained in JARs.
