  • Constructor Details

    • RedisQueueMessageDrivenEndpoint

      public RedisQueueMessageDrivenEndpoint(String queueName, RedisConnectionFactory connectionFactory)
      Parameters:
      queueName - Must not be an empty String
      connectionFactory - Must not be null

  • Method Details

    • setApplicationEventPublisher

      public void setApplicationEventPublisher(ApplicationEventPublisher applicationEventPublisher)
      Specified by:
      setApplicationEventPublisher in interface ApplicationEventPublisherAware

    • setBeanClassLoader

      public void setBeanClassLoader(ClassLoader beanClassLoader)
      Specified by:
      setBeanClassLoader in interface BeanClassLoaderAware

    • setSerializer

      public void setSerializer(RedisSerializer<?> serializer)

    • setExpectMessage

      public void setExpectMessage(boolean expectMessage)
      When data is retrieved from the Redis queue, does the returned data represent just the payload for a Message, or does the data represent a serialized Message?. expectMessage defaults to false. This means the retrieved data will be used as the payload for a new Spring Integration Message. Otherwise, the data is deserialized as Spring Integration Message.
      Parameters:
      expectMessage - Defaults to false

    • setReceiveTimeout

      public void setReceiveTimeout(long receiveTimeout)
      This timeout (milliseconds) is used when retrieving elements from the queue specified by boundListOperations.

      If the queue does contain elements, the data is retrieved immediately. However, if the queue is empty, the Redis connection is blocked until either an element can be retrieved from the queue or until the specified timeout passes.

      A timeout of zero can be used to block indefinitely. If not set explicitly the timeout value will default to 1000

      See also: https://redis.io/commands/brpop

      Parameters:
      receiveTimeout - Must be non-negative. Specified in milliseconds.

    • setTaskExecutor

      public void setTaskExecutor(Executor taskExecutor)

    • setRecoveryInterval

      public void setRecoveryInterval(long recoveryInterval)

    • setRightPop

      public void setRightPop(boolean rightPop)
      Specify if POP operation from Redis List should be BRPOP or BLPOP.
      Parameters:
      rightPop - the BRPOP flag. Defaults to true.

      4.3

    • doStart

      protected void doStart()
      Description copied from class: MessageProducerSupport

    • getQueueSize

      @ManagedMetric public long getQueueSize()
      Returns the size of the Queue specified by boundListOperations. The queue is represented by a Redis list. If the queue does not exist 0 is returned. See also https://redis.io/commands/llen
      Returns:
