Spring-Amqp MessageListener详解

在使用Spring集成RabbitMQ时，需要监听RabbiMQ消息。一般选择性实现下面俩接口：

MessageListener   只能获取到Message信息

ChannelAwareMessageListener  能获取到Message以及Channel信息

不同点在于channel可以手工确认消息以及拒绝

public class TestMessageListener implements ChannelAwareMessageListener {
 
    private static final Logger logger = LoggerFactory.getLogger(TraceAnalyzeListener.class);
 
    @Autowired
    private TraceAnalyzeService traceAnalyzeService;
    
    @Autowired
    private ElasticOperationService elasticOperationService;
    
    @Autowired
    private RedisTemplate<String, String> redisTemplate;
    
    @Autowired
    private TraceMessageSender traceMessageSender;
    
    @Override
    public void onMessage(Message message, Channel channel) throws Exception {
	
	   //消息的标识，false只确认当前一个消息收到，true确认所有consumer获得的消息
	   //channel.basicAck(message.getMessageProperties().getDeliveryTag(), false); //确认成功收到消息
	   //ack返回false，并重新回到队列，api里面解释得很清楚
	   //channel.basicNack(message.getMessageProperties().getDeliveryTag(), false, true);
	   //拒绝消息
	   //channel.basicReject(message.getMessageProperties().getDeliveryTag(), true);
    }
}
