WebSocketHandlerRegistration

Direct Known Subclasses:

ServletWebSocketHandlerRegistration

public abstract class AbstractWebSocketHandlerRegistration<M>
extends java.lang.Object
implements WebSocketHandlerRegistration

Method Detail

addHandler

public WebSocketHandlerRegistration addHandler(WebSocketHandler handler,
                                               java.lang.String... paths)

Description copied from interface: WebSocketHandlerRegistration

Add more handlers that will share the same configuration (interceptors, SockJS config, etc).

Specified by:

addHandler in interface WebSocketHandlerRegistration

setHandshakeHandler

public WebSocketHandlerRegistration setHandshakeHandler(@Nullable
                                                        HandshakeHandler handshakeHandler)

Description copied from interface: WebSocketHandlerRegistration

Configure the HandshakeHandler to use.

Specified by:

setHandshakeHandler in interface WebSocketHandlerRegistration

getHandshakeHandler

@Nullable
protected HandshakeHandler getHandshakeHandler()

addInterceptors

public WebSocketHandlerRegistration addInterceptors(HandshakeInterceptor... interceptors)

Description copied from interface: WebSocketHandlerRegistration

Configure interceptors for the handshake request.

Specified by:

addInterceptors in interface WebSocketHandlerRegistration

setAllowedOrigins

public WebSocketHandlerRegistration setAllowedOrigins(java.lang.String... allowedOrigins)

Description copied from interface: WebSocketHandlerRegistration

Configure allowed Origin header values. This check is mostly designed for browser clients. There is nothing preventing other types of client to modify the Origin header value.

When SockJS is enabled and origins are restricted, transport types that do not allow to check request origin (Iframe based transports) are disabled. As a consequence, IE 6 to 9 are not supported when origins are restricted.

Each provided allowed origin must start by "http://", "https://" or be "*" (means that all origins are allowed). By default, only same origin requests are allowed (empty list).

Specified by:

setAllowedOrigins in interface WebSocketHandlerRegistration

withSockJS

public SockJsServiceRegistration withSockJS()

Description copied from interface: WebSocketHandlerRegistration

Enable SockJS fallback options.

Specified by:

withSockJS in interface WebSocketHandlerRegistration

getInterceptors

protected HandshakeInterceptor[] getInterceptors()

getSockJsServiceRegistration

@Nullable
protected SockJsServiceRegistration getSockJsServiceRegistration()

Expose the SockJsServiceRegistration -- if SockJS is enabled or null otherwise -- so that it can be configured with a TaskScheduler if the application did not provide one. This should be done prior to calling getMappings().

getMappings

protected final M getMappings()

createMappings

protected abstract M createMappings()

addSockJsServiceMapping

protected abstract void addSockJsServiceMapping(M mappings,
                                                SockJsService sockJsService,
                                                WebSocketHandler handler,
                                                java.lang.String pathPattern)

addWebSocketHandlerMapping

protected abstract void addWebSocketHandlerMapping(M mappings,
                                                   WebSocketHandler wsHandler,
                                                   HandshakeHandler handshakeHandler,
                                                   HandshakeInterceptor[] interceptors,
                                                   java.lang.String path)
