This turned into a rather huge affair since it led to the introduction of a new AutowireCandidateResolver implementation in the spring-context module. That ACR impl is now being set through AnnotationConfigUtils; GenericApplicationContext and co do not set a default QualifierAnnotationAutowireCandidateResolver anymore (which has always been a smell anyway). At the same time, dependency ordering has moved from AutowiredAnnotationBeanPostProcessor to DefaultListableBeanFactory itself through a "dependencyComparator" strategy, applying to constructor dependencies and lazy resolution proxies as well.

Added AsyncRestTemplate, the asynchronous counterpart to the
RestTemplate that was introduced in Spring 3. All methods on the
AsyncRestTemplate are similar to those found on the synchronous
RestTemplatem, except that they return Future wrappers instead of
concrete results.
To enable this, this commit introduces the AsyncClientHttpRequest and
AsyncClientHttpRequestFactory, similar to the ClientHttpRequest and
ClientHttpRequestFactory, except that ClientHttpRequest returns a
Future<ClientHttpResponse> for the execute method. Two implementations
of these interfaces are provided, one based on the HttpURLConnection
incombination with a Spring AsyncTaskExecutor and one based on Apache
HttpComponents HttpAsyncClient.

ResourceHttpMessageConverter tries to use the filename to determine the
media type, but for Resource implementations such as ByteArrayResource
it is null, which causes NullPointerException. The fix checks whether
getFilename returns null before attempting to determine the media type
by it.
Issue: SPR-10848
MimeType is available in core-spring and does not include support
for quality parameters and media used in HTTP content negotiation.
The MediaType sub-class in org.springframework.http adds q-parameters.
The method returning query parameters now returns only query string
parameters as opposed to any Servlet request parameter.
This commit also adds a ReadOnlyMultiValueMap.
A getCookies method is now available on ServerHttpRequest with one
ServletServerCookie implementation that wraps a Servlet cookie.
The SockJS service makes use of this to check for an existing session
cookie in the request.
- Added org.springframework.http.StreamingHttpOutputMessage, which
allows for a settable request body (as opposed to an output stream).
- Added http.client.HttpComponentsStreamingClientHttpRequest, which
implements the above mentioned interface, mapping setBody() to a
setEntity() call on the Apache HttpClient HttpEntityEnclosingRequest.
- Added a 'bufferRequestBody' property to the
HttpComponentsClientHttpRequestFactory. When this property is set to
false (default is true), we return a
HttpComponentsStreamingClientHttpRequest instead of a (request
buffering) HttpComponentsClientHttpRequest.

SPR-10402 in Spring Framework 3.2.3 treated empty request parameter
values as missing values, if the empty value was turned into a null
by a PropertyEditor or Converter. This caused the regression.
Issue: SPR-10578, SPR-10402, SPR-10584
Prior to this commit the Spring Framework did not provide a public means
for scanning for available server ports. However, the Spring Framework
internally used a FreePortScanner in integration tests within its own
test suite. Furthermore, Spring Integration 2.2 provides similar support
in a SocketUtils class in the spring-integration-test module.
This commit introduces SocketUtils in spring-core to replace the
FreePortScanner which was previously only used internally within
Spring's test suite. This new implementation is inspired by both Spring
Framework's FreePortScanner and Spring Integration's SocketUtils and
consequently attempts to merge the best of both previous
implementations.
Issue: SPR-8032
If type conversion turns an empty request parameter value (i.e. "") to
null, we should treat it as a missing value. By default the
ConversionService doesn't change empty strings and therefore one must
explicitly convert them to null for example by registering a
StringTrimmerEditor with emptyAsNull=true.

Previously ContentNegotiationManager continued with the next
ContentNegotiationStrategy only if the current one returned an empty
list. Now it also does that if the current ContentNegotiationStrategy
returns "*/*". Since the absence of an Accept header and "*/*" have
the same meaning, this allows a default content type to be used in
either case.
Issue: SPR-10513
Check for an empty fragment in UriComponentsBuilder.fromUriString(...)
to prevent the invocation of fragment(...).
Previously, UriComponentsBuilder.fromUriString(...) threw an exception
in the case of an empty fragment being provided (e.g. /example#).
Issue: SPR-10363
MockServletContext.getMimeTypes now returns null if the Java Activation
Framework returns "application/octet-stream", which is the default
media type it returns if the mime type is unknown. This enforces the
contract for ServletContext.getMimeTypes (return null for uknown mime
types) but does mean "application/octet-stream" cannot be returned.
Issue: SPR-10334
Add setOutputStreaming on SimpleClientHttpRequestFactory to allow the
disabling of 'output streaming' mode on the underlying connection so
that authentication and redirection can be handled automatically.
Issue: SPR-9617
Prior to this commit several HTTP classes made use of FileCopyUtils
when reading from or writing to streams. This has the unfortunate
side effect of closing streams that should really be left open.
The problem is particularly noticeable when dealing with a
FormHttpMessageConverter that is writing a multi-part response.
Relevant HTTP classes have now been refactored to make use of a new
StreamUtils class that works in a similar way FileCopyUtils but does
not close streams.
The NonClosingOutputStream class from SimpleStreamingClientHttpRequest
has also been refactored to a StreamUtils method.
Issue: SPR-10095
Update HierarchicalUriComponents.toUri() to only prepend a missing '/'
when the scheme, user info, host or port are specified. This makes
the toUri() method behave in the same way as .toUriString() and allows
relative URIs to be created.
