Before this change, detection of X-Forwarded-* headers was only built
into ServletUriComponentsBuilder.
This change adds a new method for creating a UriComponentsBuilder from
an existing HttpRequest. This is equivalent to the fromUri method +
X-Forwarded-* header values.
Prior to this commit, HTTP responses without body (response status 204
or 304, Content-Length: 0) were handled properly by RestTemplates. But
some other cases were not properly managed, throwing exceptions for
valid HTTP responses.
This commit better handles HTTP responses, using a response wrapper that
can tell if a response:
* has no message body (HTTP status 1XX, 204, 304 or Content-Length:0)
* has an empty message body
This covers rfc7230 Section 3.3.3.

Prior to this commit, the `ContentCachingRequestWrapper` class would
cache the response content only if the reponse would be consumed using
its InputStream. In case of a Form request, Spring MVC consumes the
response using the `getParameter*` Servlet API methods. This causes the
cached content to never be written.
This commit makes the `ContentCachingResponseWrapper` write the request
body to the cache buffer by using the `getParameter*` API, thus avoiding
those issues.

This change deprecates the maxRequestSize property and adds
maxResponseSize instead. The latter is required to create Netty's
HttpObjectAggregator and aggregates responses.
The maxRequestSize property is already removed in the master branch
and will not be available starting with 4.2.

Previously the default settings of a custom HttpClient were always
ignored since a RequestConfig instance was always set no matter if
some customizations were applied or not.
This commit keeps an internal RequestConfig object instance that is
only initialized if the user applies a customization. If he does not, the
default settings of the HttpClient are used as it should.
Note that if the HttpComponents API exposed the default RequestConfig
of a given HttpClient, we would be able to merge our customizations with
the one specified by the client. Unfortunately, such API does not exist
and the "defaultSettingsOfHttpClientLostOnExecutorCustomization" test
illustrates that limitation.

Before this change attributes listed with @SessionAttributes would not
be saved in the session when there was a redirect and the controller
method declared a parameter of type RedirectAttributes.
This change ensures it's the "default" model that is always the one
checked for @SessionAttributes under all circumstances since
RedirectAttributes is really only meant to provide String values to
insert into or append to the the redirect URL.

Prior to this commit it was not possible to easily customize the
connection request timeout used by the HttpClient. Both
`HttpComponentsClientHttpRequestFactory` and
`HttpComponentsClientHttpRequestFactoryTests` have been updated to
support a `connectionRequestTimeout` property.
Issue: SPR-12166
Previously, HttpComponentsHttpInvokerRequestExecutor was not compatible
with the new API of HttpComponents 4.3. Specifically, it is not possible
to update the socket and read timeouts on the HttpClient itself anymore.
We actually already updated HttpComponentsClientHttpRequestFactory for a
similar problem in SPR-11442: if we detect an older HttpClient
implementation, we update the timeout directly on the client. If that's
not the case, we keep the value in the factory itself and use it when a
new HttpRequest needs to be created.
This commit also uses the new API to create a default HttpClient and
therefore requires HttpComponents 4.3. As mentioned above, it is still
possible to use deprecated HttpClient instances against this executor.

This commit introduces the SpringHandlerInstantiator
class, a Jackson HandlerInstantiator that allows to autowire
Jackson handlers (JsonSerializer, JsonDeserializer, KeyDeserializer,
TypeResolverBuilder and TypeIdResolver) if needed.
SpringHandlerInstantiator is automatically used with
@EnableWebMvc and <mvc:annotation-driven />.
Issue: SPR-10768
Prior to this change, RestTemplate returned an empty response body if:
* HTTP return status 204 or 304
* Content-length header equals 0
This change adds a new condition for this, better supporting RFC7230
section 3.4, for connections that are closed without response body:
* No Content-length header
* No Transfer-encoding: chunked header value
* a Connection: close header value
See SPR-7911 for previous efforts in that space.

With this commit, Jackson builder is now used in spring-websocket
to create the ObjectMapper instance.
It is not possible to use the builder for spring-messaging
and spring-jms since these modules don't have a dependency on
spring-web, thus they now just customize the same features:
- MapperFeature#DEFAULT_VIEW_INCLUSION is disabled
- DeserializationFeature#FAIL_ON_UNKNOWN_PROPERTIES is disabled
Issue: SPR-12293
FormHttpMessageConverter incorrectly determines that the media type
"multipart/form-data; charset=utf-8" is not multipart. This commit
allows the media type to contain a charset parameter.
The following commit allowed HTTP DELETE with body:
584b831bb9
However it broke buffered requests even without a body since JDK 1.6
and 1.7 do not support calls to getOutputStream with HTTP DELETE.
This commit set the doOutput flag back to false if the actual buffered
body is 0 length.
Issue: SPR-12361
With SPR-9293, it is now possible to HTML escape text while taking into
account the current response encoding. When using UTF-* encodings, only
XML markup significant characters are escaped, since UTF-* natively
support those characters.
This commit adds a new servlet context parameter to enable this fix by
default in a Spring MVC application:
<context-param>
<param-name>responseEncodedHtmlEscape</param-name>
<param-value>true</param-value>
</context-param>
