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.

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.

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

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.
Instead of having to use the default constructor then calling
setObjectMapper(ObjectMapper), these constructors allow
MappingJackson2JsonView and MappingJackson2XmlView to be created and
configured with the desired object mapper in one step.
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.

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.

When resolving resources, the PathResourceResolver creates a Resource
instance and checks whether this resource `exists()` and `isReadable()`.
While that last call returns false for folders on the file system, both
calls return true for folders located inside JARs.
If a JAR location is configured as a resource location, then
PathResourceResolver can resolve folders in JARs as valid locations and
candidates for paths resolution.
Prior to this change, the PathResourceResolver would resolve "" as a
valid resource path (here, the "/META-INF/resources/webjars" if
configured, for example) and return a "" path for this resource,
effectively turning all "/" URLs into empty ones "".
This commit fixes the resolveUrlPathInternal implementation by not
allowing empty paths as valid resource paths.

This commit adds a new sharedEngine property to ScriptTemplateConfigurer
and ScriptTemplateView in order to support non thread-safe ScriptEngine
implementations like Nashorn.
When this flag is set to false, the engine is retrieved from a
ThreadLocal<ScriptEngine> field instead of a ScriptEngine one.
Also as part of this commit, all the initialization logic has been moved from
ScriptTemplateConfigurer to ScriptTemplateView since the script engine can
now be lazily initialized multiple time in the view when sharedEngine is
set to false.

This commit introduces the following changes:
- The new CorsConfigurationMapping class allows to share the mapped
CorsConfiguration logic between AbstractHandlerMapping and CorsFilter
- In AbstractHandlerMapping, the Map<String, CorsConfiguration>
corsConfiguration property has been renamed to corsConfigurations
- CorsFilter allows to process CORS requests at filter level, using any
CorsConfigurationSource implementation (for example
CorsConfigurationMapping)

By default, RedirectViews have http10Compatible set to true, which means
that they use HTTP 302 as a default HTTP response status. Setting this
property to false make RedirectViews use HTTP 303 by default.
Now when set to false, RedirectViews also don't use the
RESPONSE_STATUS_ATTRIBUTE request attribute as a response HTTP if it is
available.
This commit makes both configuration choices behave the same regarding
this request attribute: use it as a response status if it's available.

As of SPR-11792, WebContentGenerator and WebContentInterceptor offer
new APIs and new behavior regarding HTTP caching, including the use of a
new CacheControl class.
Those changes broke part of the behavior in WebContentInterceptor. This
class allows to override the global Cache configuration at the Generator
level, using specific mappings. Prior to this change, those mappings
would not properly apply the HTTP caching configuration when using
deprecated configuration settings in WebContentGenerator.
This change fixes those backwards compatibility issues for
WebContentInterceptor users.
Issue: SPR-13207
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.
