Examples of org.springframework.messaging.support.ImmutableMessageChannelInterceptor

org.springframework.messaging.support.ImmutableMessageChannelInterceptor
A simpler interceptor that calls {@link MessageHeaderAccessor#setImmutable()}on the headers of messages passed through the preSend method.
When configured as the last interceptor in a chain, it allows the component sending the message to leave headers mutable for interceptors to modify prior to the message actually being sent and exposed to concurrent access. @author Rossen Stoyanchev @since 4.1.2

      public Message<?> preSend(Message<?> message, MessageChannel channel) {
        mutable.set(MessageHeaderAccessor.getAccessor(message, MessageHeaderAccessor.class).isMutable());
        return message;
      }
    });
    channel.addInterceptor(new ImmutableMessageChannelInterceptor());


    StompSubProtocolHandler handler = new StompSubProtocolHandler();
    handler.afterSessionStarted(this.session, channel);


    TextMessage message = StompTextMessageBuilder.create(StompCommand.CONNECT).build();
