Interface WebSocketMessageBrokerConfigurer

public interface WebSocketMessageBrokerConfigurer
Defines methods for configuring message handling with simple messaging protocols (e.g. STOMP) from WebSocket clients.

Typically used to customize the configuration provided via @EnableWebSocketMessageBroker.

  • Method Details

    • 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.

    • getPhase

      @Nullable default Integer getPhase()
      Return the phase that WebSocket message handling beans of type SmartLifecycle should run in.

      The default implementation returns null which allows other configurers to decide. As soon as any configurer returns a value, that value is used. If no configurer returns a value, then 0 is used.

      It is recommended to use a phase value such as 0 in order to ensure that components start before the web server in Spring Boot application.
