    • RedisQueueInboundGateway

      public RedisQueueInboundGateway​(java.lang.String queueName, org.springframework.data.redis.connection.RedisConnectionFactory connectionFactory)
      Parameters:
      queueName - Must not be an empty String
      connectionFactory - Must not be null

  • Method Details

    • setExtractPayload

      public void setExtractPayload​(boolean extractPayload)

    • setApplicationEventPublisher

      public void setApplicationEventPublisher​(org.springframework.context.ApplicationEventPublisher applicationEventPublisher)
      Specified by:
      setApplicationEventPublisher in interface org.springframework.context.ApplicationEventPublisherAware

    • setBeanClassLoader

      public void setBeanClassLoader​(java.lang.ClassLoader beanClassLoader)
      Specified by:
      setBeanClassLoader in interface org.springframework.beans.factory.BeanClassLoaderAware

    • setSerializer

      public void setSerializer​(org.springframework.data.redis.serializer.RedisSerializer<?> serializer)

    • 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.
