rabbitmq出现的问题

An unexpected connection driver error occured
java.net.SocketException: socket closed异常

然后发现是自己rabbit连接时写错了

 

 有两个账户，写错了账户密码，然后出现了连接错误

 

发送短信时，队列里有消息没清空会报错

org.springframework.amqp.rabbit.listener.exception.ListenerExecutionFailedException

 

队列不存在时会报错

org.springframework.amqp.rabbit.listener.BlockingQueueConsumer$DeclarationException: Failed to declare queue(s):[sms_queue]

 

 

Execution of Rabbit message listener failed.

org.springframework.amqp.rabbit.support.ListenerExecutionFailedException: Listener method 'public void com.ifjanuary.mq.SendSmsCodeConsumer.reciver(java.lang.String)' threw exception

额。。最终发现是监听器没写对

@Component
public class StarterupListener implements ApplicationListener<ContextRefreshedEvent> {

    @Resource
    private RedisTemplate<String,Object> redisTemplate;

    @Override
    public void onApplicationEvent(ContextRefreshedEvent event) {
        RedisUtils.register(redisTemplate);
    }

}
