方法详细资料

• preSend

  public Message<?> preSend​(Message<?> message,
                            MessageChannel channel)

  从接口复制的说明: ChannelInterceptor
  Invoked before the Message is actually sent to the channel. This allows for modification of the Message if necessary. If this method returns null then the actual send invocation will not occur.

  指定者:

  preSend 在接口中 ChannelInterceptor

• postSend

  public void postSend​(Message<?> message,
                       MessageChannel channel,
                       boolean sent)

  从接口复制的说明: ChannelInterceptor
  Invoked immediately after the send invocation. The boolean value argument represents the return value of that invocation.

  指定者:

  postSend 在接口中 ChannelInterceptor

• afterSendCompletion

  public void afterSendCompletion​(Message<?> message,
                                  MessageChannel channel,
                                  boolean sent,
                                  Exception ex)

  从接口复制的说明: ChannelInterceptor
  Invoked after the completion of a send regardless of any exception that have been raised thus allowing for proper resource cleanup.

  Note that this will be invoked only if ChannelInterceptor.preSend(org.springframework.messaging.Message<?>, org.springframework.messaging.MessageChannel) successfully completed and returned a Message, i.e. it did not return null.

  指定者:

  afterSendCompletion 在接口中 ChannelInterceptor

• preReceive

  public boolean preReceive​(MessageChannel channel)

  从接口复制的说明: ChannelInterceptor
  Invoked as soon as receive is called and before a Message is actually retrieved. If the return value is 'false', then no Message will be retrieved. This only applies to PollableChannels.

  指定者:

  public Message<?> postReceive​(Message<?> message,
                                MessageChannel channel)
