类 DefaultQueueListenerSubscriber

java.lang.Object

com.baidu.bigpipe.driver.DefaultQueueListenerSubscriber

所有已实现的接口:

QueueListenerSubscriber

public class DefaultQueueListenerSubscriber
extends Object
implements QueueListenerSubscriber

实现QueueListenerSubscriber接口，封装 AsynchronousQueueSubscriberFactory, 异步订阅消息并消费消息，消费步骤如下：

• 监听并接收消息,通过 AsynchronousQueueSubscriber实现
• 转化byte[]类型消息成为java对象,通过MessageBodyConverter实现
• 消费消息，通过BigpipeQueueMessageListener实现
• 消息成功消费后,如果不抛出异常,
• 通过AsynchronousQueueSubscriberBioImpl.sendAcknowledgement(com.baidu.bigpipe.protocol.QueueMessage, boolean)消息回执
