Method Summary

Modifier and Type	Method and Description
default void	addArgumentResolvers(List<HandlerMethodArgumentResolver> argumentResolvers) Add resolvers to support custom controller method argument types.
default void	addReturnValueHandlers(List<HandlerMethodReturnValueHandler> returnValueHandlers) Add handlers to support custom controller method return value types.
default void	configureClientInboundChannel(ChannelRegistration registration) Configure the MessageChannel used for incoming messages from WebSocket clients.
default void	configureClientOutboundChannel(ChannelRegistration registration) Configure the MessageChannel used for outbound messages to WebSocket clients.
default void	configureMessageBroker(MessageBrokerRegistry registry) Configure message broker options.
default boolean	configureMessageConverters(List<MessageConverter> messageConverters) Configure the message converters to use when extracting the payload of messages in annotated methods and when sending messages (e.g.
default void	configureWebSocketTransport(WebSocketTransportRegistration registry) Configure options related to the processing of messages received from and sent to WebSocket clients.
default void	registerStompEndpoints(StompEndpointRegistry registry) Register STOMP endpoints mapping each to a specific URL and (optionally) enabling and configuring SockJS fallback options.

Method Detail

registerStompEndpoints

default void registerStompEndpoints(StompEndpointRegistry registry)

Register STOMP endpoints mapping each to a specific URL and (optionally) enabling and configuring SockJS fallback options.

configureWebSocketTransport

default void configureWebSocketTransport(WebSocketTransportRegistration registry)

Configure options related to the processing of messages received from and sent to WebSocket clients.

configureClientInboundChannel

default void configureClientInboundChannel(ChannelRegistration registration)

Configure the MessageChannel used for incoming messages from WebSocket clients. By default the channel is backed by a thread pool of size 1. It is recommended to customize thread pool settings for production use.

configureClientOutboundChannel

default void configureClientOutboundChannel(ChannelRegistration registration)

Configure the MessageChannel used for outbound messages to WebSocket clients. By default the channel is backed by a thread pool of size 1. It is recommended to customize thread pool settings for production use.

addArgumentResolvers

default void addArgumentResolvers(List<HandlerMethodArgumentResolver> argumentResolvers)

Add resolvers to support custom controller method argument types.

This does not override the built-in support for resolving handler method arguments. To customize the built-in support for argument resolution, configure SimpAnnotationMethodMessageHandler directly.

Parameters:

argumentResolvers - the resolvers to register (initially an empty list)

Since:

4.1.1

addReturnValueHandlers

default void addReturnValueHandlers(List<HandlerMethodReturnValueHandler> returnValueHandlers)

Add handlers to support custom controller method return value types.

Using this option does not override the built-in support for handling return values. To customize the built-in support for handling return values, configure SimpAnnotationMethodMessageHandler directly.

Parameters:

returnValueHandlers - the handlers to register (initially an empty list)

Since:

4.1.1

configureMessageConverters

default boolean configureMessageConverters(List<MessageConverter> messageConverters)

Configure the message converters to use when extracting the payload of messages in annotated methods and when sending messages (e.g. through the "broker" SimpMessagingTemplate).

The provided list, initially empty, can be used to add message converters while the boolean return value is used to determine if default message should be added as well.

Parameters:

messageConverters - the converters to configure (initially an empty list)

Returns:

whether to also add default converter or not

configureMessageBroker

default void configureMessageBroker(MessageBrokerRegistry registry)

Configure message broker options.
