Issue: SPR-9488

This commit adds support to read and write JSON using the Google Gson
library. GsonHttpMessageConverter offers default Gson configuration, but
can be customized by using GsonFactoryBean. GsonFactoryBean includes
several convenience properties for configuring the internal GsonBuilder
and the resulting Gson object.

By default Gson converts byte arrays to JSON arrays instead of a Base64
encoded string. GsonBase64ByteArrayJsonTypeAdapter provides support to
read and write Base64 encoded byte arrays, and can be enabled in
GsonFactoryBean.

RestTemplate will enable GsonHttpMessageConverter only if Jackson 2 is
not found on the class path, because by default GsonHttpMessageConverter
supports the same media types as Jackson.

Prior to this commit, CacheResolver could not be configured through
the XML namespace (i.e. cache:annotation-driven). This is now the
case.

Issue: SPR-11490

Issue: SPR-9899

This commit adds the necessary infrastructure to handle exceptions
thrown by a cache provider in both Spring's and JCache's caching
abstractions.

Both interceptors can be configured with a CacheErrorHandler that
defines several callbacks on typical cache operations. In particular,
handleCacheGetError can be implemented in such a way that an
exception thrown by the provider is handled as a cache miss by the
caching abstraction.

The handler can be configured with both CachingConfigurer and the
XML namespace (error-handler property)

(cherry picked from commit 54636b3f)

Consistent use of IllegalStateException instead of InternalError for UnsupportedEncodingException cause

UriComponentsBuilder.toUriString instead of RequestContext.getMvcUrl (breaking cyclic dependency between web.servlet.support and web.servlet.mvc)

This commit also includes a JUnit 4 style revision of StringUtilsTests and ObjectUtilsTests.

Consistently log Class.getName() instead of Class.toString(), avoiding double class term in log message

The newly added support for ResponseBodyInterceptor is a good fit for
the (also recently added) support for the Jackson @JsonView annotation.

This change refactors the original implementation of @JsonView support
for @ResponseBody and ResponseEntity controller methods this time
implemented as an ResponseBodyInterceptor.

Issue: SPR-7156

This change introduces a new ResponseBodyInterceptor interface that can
be used to modify the response after @ResponseBody or ResponseEntity
methods but before the body is actually written to the response with the
selected HttpMessageConverter.

The RequestMappingHandlerAdapter and ExceptionHandlerExceptionResolver
each have a property to configure such interceptors. In addition both
RequestMappingHandlerAdapter and ExceptionHandlerExceptionResolver
detect if any @ControllerAdvice bean implements ResponseBodyInterceptor
and use it accordingly.

ServletRequestAttributes skips well-known immutable values when updating accessed session attributes

This commit adds a JMS implementation of MessageSendingOperations,
allowing to send JMS messages using Spring's standard Messaging
abstraction.

MessagingMessageConverter is a standard JMS's MessageConverter that
can convert Spring's Message to JMS message and vice versa. Existing
infrastructure has been updated to use this implementation.

Servlet 3 multipart request implements getParameterNames defensively (for WebLogic 12 compatibility)

This commit also includes lazy resolution support for StandardServletMultipartResolver, along the lines of existing lazy mode in CommonsMultipartResolver.

Properly evaluate @Conditional in case of multiple imports for same config class (fixing regression in Spring Boot)

Issue: SPR-11788
(cherry picked from commit 7d78c651)

Servlet/PortletResponse supported as a resolvable dependency now (in particular for web controllers)

This feature required support for response exposure on Servlet/PortletRequestAttributes, instead of just in the Servlet/PortletWebRequest subclasses.

Spring MVC now supports Jackon's serialization views for rendering
different subsets of the same POJO from different controller
methods (e.g. detailed page vs summary view).

This commit adds a SQLErrorCodes instance for SAP DB, based on a
contribution from Andrew Clemons

Mostly based on SAP Hana SPS 07 with a few additional codes that are
only present is previous versions:

* -813 - Cannot connect to host somehost:30115 [Connection refused]
* -709 - Unknown host somehost:30115 [somehost], -709.]
* -708 - Cannot connect to jdbc:sap://somehost:30115 [Receive of connect failed.]
* -11210 - Invalid column index XYZ.

This commit avoids throwing JMSException from the listener execution
as this is not allowed per spec. Our SessionAwareMessageListener
gives a callback that can throw JMSException and we have "abused" it
so far.

Typical message processing goes in those 3 steps:
* Unmarshall the javax.jms.Message to the requested type
* Invoke the actual user method (including processing of method
  arguments)
* Send a reply message, if any

Those three steps have been harmonized so that they don't throw a
JMSException anymore. For the later case, introduced
ReplyFailureException as a general exception indicating the
reply message could not have been sent.
