public abstract class AbstractWebSocketHandlerRegistration<M>
extends Object
implements WebSocketHandlerRegistration

public AbstractWebSocketHandlerRegistration()

Method Details

addHandler

public WebSocketHandlerRegistration addHandler(WebSocketHandler handler,
 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(String... allowedOrigins)

Description copied from interface: WebSocketHandlerRegistration

Set the origins for which cross-origin requests are allowed from a browser. Please, refer to CorsConfiguration.setAllowedOrigins(List) for format details and considerations, and keep in mind that the CORS spec does not allow use of "*" with allowCredentials=true. For more flexible origin patterns use WebSocketHandlerRegistration.setAllowedOriginPatterns(java.lang.String...) instead.

By default, no origins are allowed. When allowedOriginPatterns is also set, then that takes precedence over this property.

Note 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.

Specified by:

setAllowedOrigins in interface WebSocketHandlerRegistration

• WebSocketHandlerRegistration.setAllowedOriginPatterns(String...)
• RFC 6454: The Web Origin Concept
• SockJS supported transports by browser

setAllowedOriginPatterns

public WebSocketHandlerRegistration setAllowedOriginPatterns(String... allowedOriginPatterns)

Description copied from interface: WebSocketHandlerRegistration

Alternative to WebSocketHandlerRegistration.setAllowedOrigins(String...) that supports more flexible patterns for specifying the origins for which cross-origin requests are allowed from a browser. Please, refer to CorsConfiguration.setAllowedOriginPatterns(List) for format details and other considerations.

By default this is not set.

Specified by:

setAllowedOriginPatterns 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()

 SockJsService sockJsService,
 WebSocketHandler handler,
