Building on the initial work for SPR-12326, this commit
addresses three problems:
Firstly the ReflectiveMethodResolver is modified to consider
a direct parameter match more important than a varargs match.
Also in that same type when there are a number of close
matches, the first one is taken rather than the last one.
Secondly more testcases and better support have been added
for the case of passing a single parameter to a varargs
accepting method.
Finally it is possible to set the root context object
indirectly and not pass it on getValue() calls to the
expression objects but not all variants of getValue()
were handling that. This is now fixed.

This commit adds new htmlEscape methods that take the character encoding
as a parameter. According to specs and recommendations, the list of
chars to be html escaped depends on the encoding used in the response.
If the current char encoding supports chars natively, we shouldn't
escape those; of course, reserved chars (<,>,',",&) should always be
escaped.

Issue: SPR-9293
The argument processing for compiling constructor references
was very basic and this fix removes that and ensures the
comprehensive logic written for method argument processing
(under SPR-12328) is now used for both method and constructor
argument handling. This fixes the reported issue and ensures
varargs constructor references can be compiled.
This also includes a couple of small fixes for the secondary
testcase reported in SPR-12326. The first is to ensure the
right root context object is used when it is passed
to getValue() indirectly through the evaluation context.
The final fix is to ensure correct boxing of primitives is
done when a method is called upon a primitive.

This fix addresses a 4.1.1 regression where a raw ResponseEntity return
value (used to return potentially a different kind of body) caused an
exception.
The regression came from the fact we now try to render a null body in
order to give ResponseBodyAdvice a chance to substitute a different
value. That in turn means we have to try to determine the body type
from the method signature.
This change improves the logic for extracting the generic parameter
type to accommodate a raw ResponseEntity class. Also we avoid raising
HttpMediaTypeNotAcceptableException if the value to be rendered is
null.

Commit https://github.com/spring-projects/spring-framework/commit/2b97d6
introduced a change where the path within the DispatcherServlet is
determined with each call to ResourceUrlProvider.getForRequestUrl.
To avoid repeating that every time a URL is encoded through the
response, we now cache the result of the lookupPath determination in
ResourceUrlEncodingFilter.
Issue: SPR-12332
The use of the HandlerMapping.PATH_WITHIN_HANDLER_MAPPING_ATTRIBUTE
in ResourceUrlProvider (as a way of saving lookup path determination)
leads to incorrect results. For example when the request is forwarded
the current requestUri may no longer be compariable to the value of the
PATH_WITHIN_HANDLER_MAPPING_ATTRIBUTE. Also where the request is mapped
using a pattern, the value of PATH_WITHIN_HANDLER_MAPPING_ATTRIBUTE is
not the same as the lookup path.
This change removes the use of the attribute from ResourceUrlProvider
and instead always determines the lookup path when getForRequestUrl
is called.
Issue: SPR-12332
This change introduces support for compilation of expressions
involving inline lists, string concatenation and method
invocations where the method being invoked is declared
with a varargs parameter. It also fixes a problem with
compiling existing method invocations where the target
method is on a non public type.
Issue: SPR-12328
Before this change, the type of asynchronously produced return values
(e.g. Callable, DeferredResult, ListenableFuture) could not be
properly determined with an actual resulting value of null. Or even
with an actual value returned, the generic type could not be properly
determined. This change fixes both of those issues.
Issue: SPR-12287
Prior to this commit, the cache operation metadata cache was not
updated for a method not using the JCache annotations. This means
that every execution of said method was going through the process
of identifying if it was using the cache or not.
This commit adds a default placeholder identifying the absence of
metadata; this allows to flag such method as not having any metadata
at all.
Issue: SPR-12337
The getForRequestUrl method of ResourceUrlProvider uses the
HandlerMapping.PATH_WITHIN_HANDLER_MAPPING_ATTRIBUTE attribute to
determine the relevant portion of the resource URL path.
However there are cases when that attribute may not have a leading
(e.g. when the current URL was matched to a prefix-based pattern
and hence extracted via PathMatcher#extractPathWithinPattern), which
interferes with the matching of resource URL paths to patterns.
This change ensures a leading slash is present
Issue: SPR-12281
Snake YAML allows for duplicate keys in map nodes. See
https://code.google.com/p/snakeyaml/issues/detail?id=199
This commit uses a dedicated Constructor extension that explicitly
checks for such duplicate keys.
Issue: SPR-12318
The resourceHandlerMapping in the MVC Java config is not configured
with any interceptors, and in particular those added through the
InterceptorRegistry, which are otherwise added to all other handler
mapping beans created by the config. This means that the
ResourceUrlProviderExposingInterceptor (added in 4.0) is also not
used for resource requests.
This change ensures the ResourceUrlProviderExposingInterceptor is
configured on the resourceHandlerMapping.
