This commit introduces a new OriginHandshakeInterceptor. It filters
Origin header value against a list of allowed origins.
AbstractSockJsService as been modified to:
- Reject CORS requests with forbidden origins
- Disable transport types that does not support CORS when an origin
check is required
- Use the Origin request header value instead of "*" for
Access-Control-Allow-Origin response header value
(mandatory when Access-Control-Allow-Credentials=true)
- Return CORS header only if the request contains an Origin header
It is possible to configure easily this behavior thanks to JavaConfig API
WebSocketHandlerRegistration#addAllowedOrigins(String...) and
StompWebSocketEndpointRegistration#addAllowedOrigins(String...).
It is also possible to configure it using the websocket XML namespace.
Please notice that this commit does not change the default behavior:
cross origin requests are still enabled by default.

This change adds a ChannelInterceptor that flips the immutable flag on
messages being sent. This allows components sending messages to leave
the message mutable for interceptors to further apply modifications
before the message is sent (and exposed to concurrency).
The interceptor is automatically added with the STOMP/WebSocket Java
and XML config and the StompSubProtocolHandler leaves parsed incoming
messages mutable so they can be further modified before being sent.
Issue: SPR-12321
The WebSocketMessageBroker config now allows wrapping the
SubProtocolWebSocketHandler to enable advanced use cases that may
require access to the underlying WebSocketSession.

This change adds a new XhrTransport for the SockJs client
implementation. This transport is based on `UndertowClient`,
Undertow's HTTP client.
Note that this transport can be customized with an OptionMap that is
used by the Xnio worker backing the I/O communications (see
http://xnio.jboss.org).
Implementation tested with undertow 1.0.36, 1.1.0.RC3, 1.2.0.Beta1.
Issue: SPR-12008
This change adds a "Vary: Origin" HTTP response header for /info and
/iframe SockJS endpoints.
This is preventing proxies and browsers from caching a response and
reusing it for an invalid Origin.

This change uses a ChannelInterceptor (inserted at index 0) to detect
when a DISCONNECT message is precluded from being sent on the
clientInboundChannel. This can happen if another interceptor allows
a runtime exception out from preSend or returns false.
It is crucial for such messages to be processed, so when detected
they're processed still.
Issue: SPR-12218
Before this change the SockJsWebSocketHandler precluded determination
of the sub-protocols by wrapping the actual target handler.
After this change SockJsWebSocketHandler implements SubProtocolCapable
and returns the list of sub-protocols from the wrapped handler.
Before this change the DefaultHandshakeHandler by default passed the
list of requested WebSocket extensions as-is relying on the WebSocket
engine to remove those not supported.
This change ensures that WebSocket extensions not supported by the
runtime are proactively removed instead.
This change is preparation for SPR-11094.
This change adds a WebSocketTestServer setup method that initializes
the server and obtains a new port.
In turn AbstractWebSocketIntegrationTests invokes the new method from
its setup method thus ensuring a new port is used on every test.
In order to be able to use separators like "." (used by default
by most broker relays) instead of "/" for destination patterns
handling, the PathMatcher used in spring-messaging can now
be customized easily thanks to XML websocket namespace
or JavaConfig.
AntPathMatcher has been updated in order to use the configured path
separator instead of an hardcoded "/" for path concatenation.
Extension handling is now disabled when the "." separator is configured.
Issue: SPR-11660
Before this change WebSocketConnectionManager delegated SmartLifecycle
methods to the client instance it contained. After this change
WebSocketClient implementations are expected to implement Lifecycle
(rather than SmartLifecycle).
The need for this is even more evident with SockJsClient, which is a
WebSocketClient implementation and contains a WebSocketTransport that
in turn contains the actual WebSocketClient. In this case
WebSocketConnectionManager as the top level container is the obvious
place to configure autostartup while Lifecycle events can be
propagated all the way down to the root WebSocketClient.
This change removes most logging at INFO level and also ensures the
amount of information logged at DEBUG level is useful, brief, and
not duplicated.
Also added is custom logging for STOMP frames to ensure very readable
and consise output.
Issue: SPR-11934
This change adds collection of stats in key infrastructure components
of the WebSocket message broker config setup and exposes the gathered
information for logging and viewing (e.g. via JMX).
WebSocketMessageBrokerStats is a single class that assembles all
gathered information and by default logs it once every 15 minutes.
Application can also easily expose to JMX through an MBeanExporter.
A new section in the reference documentation provides a summary of
the available information.
Issue: SPR-11739
This change removes the recently added SockJsThreadPoolTaskScheduler
and instead builds support for the removeOnCancelPolicy property in
ThreadPoolTaskScheduler and ScheduledExecutorFactoryBean.
Issue: SPR-11918
Update WebSocketSession toString methods to include the handshake URI
and add id and URI fields to ensure they're available after close().
Log WebSocket session open and close events at INFO.
Remove trace messages for destinations that do not match.
