Prior to this change, the resource handling FixedVersionStrategy would
be applied on all links that match the configured pattern. This is
problematic for relative links and can lead to rewritten links such as
"/fixedversion/../css/main.css" which breaks.
This commit prevents that Strategy from being applied to such links.
Of course, one should avoid to use that VersionStrategy with relative
links, but this change aims at not breaking existing links even if it
means not prefixing the version as expected.

Prior to this change, the HttpEntityMethodProcessor would try to process
conditional requests that are undefined by the spec, such as:
* an HTTP GET request with "If-None-Match:*"
* a request with both "If-None-Match" and "If-Match"
* a request with both "If-None-Match" and "If-Unmodified-Since"
This commit skips the processing of those requests as conditional
requests and continues with normal request handling.

Refine the approach of having <mvc:view-resolvers> detect and use the
ContentNegotiationManager instance registered with
<mvc:annotation-driven> introduced in the last commit.
Issue: SPR-13559
The <mvc:annotation-driven> element now adds an alias when a
ContentNegotiationManager bean is registered with a custom name.
This helps <mvc:view-resolvers> to more reliably find such a custom
ContentNegotiationManager.

Prior to this change, serving resources with ResourceHttpRequestHandler
could result in NPE when requesting an existing folder located in a JAR.
This commit swallows those exceptions, as it is not possible to foresee
those cases without reading the actual resource. This result in a HTTP
200 response with a zero Content-Length instead of a HTTP 500 internal
exception.
Issue: SPR-13620
This commit migrates all remaining tests from JUnit 3 to JUnit 4, with
the exception of Spring's legacy JUnit 3.8 based testing framework that
is still in use in the spring-orm module.
Issue: SPR-13514
ResponseBodyEmitter now registers by default to receive callbacks
on timeout/completion and sets its internal "complete" flag to true
in order to prevent proactively further use of the emitter.
Issue: SPR-13498
Prior to this commit, HttpEntityMethodProcessor would process
conditional requests even if those aren't GET requests.
This is an issue for POST requests with "If-None-Match: *" headers and
many other use cases, which should not receive an HTTP 304 Not Modified
status in response.
This commit only triggers ETag/Last-Modified conditional requests bits
for GET requests.
Issue: SPR-13496
This commit introduces support for attribute overrides for
@ResponseStatus when @ResponseStatus is used as a meta-annotation on
a custom composed annotation.
Specifically, this commit migrates all code that looks up
@ResponseStatus from using AnnotationUtils.findAnnotation() to using
AnnotatedElementUtils.findMergedAnnotation().
Issue: SPR-13441
After this change, with Nashorn it is possible to use either
render(template, model) or render(template, model, url).
With JRuby or Jython, specifying the 3 parameters is mandatory.
Issue: SPR-13453
Prior to this commit, requests with an empty body and no Content-Type
header set would fail with a HttpMediaTypeNotSupportedException when
mapped to a Controller method argument annotated with
@RequestBody(required=false).
In those cases, the server implementation considers with an
"application/octet-stream" content type and polls messageconverters for
conversion. If no messageconverter is able to process this request, a
HttpMediaTypeNotSupportedException is thrown.
This change makes sure that such exceptions are not thrown if the
incoming request has:
* no body
* no content-type header
In this case, a null value is returned.
Issue: SPR-13147
Prior to this change, VersionResourceResolver and VersionStrategy would
resolve static resources using version strings. They assist
ResourceHttpRequestHandler with serving static resources. The
RequestHandler itself can be configured with HTTP caching strategies to
set Cache-Control headers.
In order to have a complete strategy with Cache-Control and ETag
response headers, developers can't reuse that version string information
and have to rely on other mechanisms (like ShallowEtagHeaderFilter).
This commit makes VersionResourceResolver use that version string to set
it as a request attribute, which will be used by the
ResourceHttpRequestHandler to write an ETag response header.
Issue: SPR-13382
Prior to this change, ResourceUrlEncodingFilter and ResourceUrlProvider
would try to resolve the resource path using the full request URL (i.e.
request path and request parameters), whereas the request path is the
only information to consider.
This would lead to StringIndexOutOfBoundsExceptions when the path +
request params information was given to the AntPathMatcher.
This commit makes the appropriate change to both
ResourceUrlEncodingFilter and ResourceUrlProvider, in order to only
select the request path.
Issue: SPR-13374
This commit introduces the following changes:
- Content type can now be properly configured
- Default content type is "text/html"
- Content type and charset are now properly set in the response
Issue: SPR-13379
In an attempt to make our Jetty-based integration tests more robust,
this commit discontinues use of SocketUtils for picking a random,
available port and instead lets the Jetty Server pick its own port.
Prior to this commit, the `ResponseStatusExceptionResolver` would use:
* `HttpServletResponse.sendError` if both a status and a reason are set
on the `@ResponseStatus` annotation
* `HttpServletResponse.setStatus` if only a status is set on the
`@ResponseStatus` annotation
This is actually a change of behavior, since this Resolver was using
`sendError` in all cases previously.
Because this change can create issues such as
https://github.com/spring-projects/spring-boot/issues/3623
this commit rollbacks those changes and clarifies the behavior on the
javadoc of the annotation itself.
Issue: SPR-11193, SPR-13226
Prior to this change, calling the `setDateHeader` method on a
MockHttpServletResponse instance (internal implementation for testing
the spring-web module) would just store the given long value in a Map,
not writing it as a formatted date String.
This can be problematic when testing features related to date headers
such as "Expires", "If-Modified-Since", "Last-Modified", etc.
This commit formats long dates into date Strings using the date format
recommended by the RFC and the GMT time zone.
As filter-based libraries and projects (such as Spring Security) may
use the "Pragma" header in HTTP responses, WebContentGenerator should
make sure that such headers are overwritten to avoid clashes with
the HTTP caching headers set by the HTTP caching configuration.
