**问题现象:RabbitMQ double ack 报错**

16:50:10.134 ERROR 17788 ---  o.s.a.r.c.CachingConnectionFactory       : 
    Channel shutdown: channel error; protocol method: #method<channel.close>(reply-code=406, reply-text=PRECONDITION_FAILED - unknown delivery tag 1, class-id=60, method-id=80)

**使用rabbitmq的时候总是报错信道关闭,而且这个错居然不影响消息队列运行。  
原因是因为进行了两次消息确认double ack.**

**yml中配置手动签收模式失效，被注解注入的SimpleRabbitListenerContainerFactory覆盖，而它默认使用了自动签收。但是消费消息的时候又手动进行channel.basicAck(deliveryTag, false)，于是导致了两次ack,所以报错。  
解决方法是在rabbitmq的factory中指定ack模式factory.setAcknowledgeMode(AcknowledgeMode.MANUAL);**

**yml配置**
