针对上述日志中产生的问题的解决方案
- 在消费者的类上面删除掉注解
@RabbitListener(queues = OfficeQueue.OFFICE_QUEUE)
- 在消费者的方法上面加上注解
@RabbitListener(queues = OfficeQueue.OFFICE_QUEUE)
- 在消费者的方法上面去掉注解
@RabbitHandler
上面的方法处理完后又出现异常（忘记记录）
- 总的意思是在说，消费者在队列中获取这条消息时，生产者那边生产的 message 是空的;
问题排查
对服务里面的各个模块生产消息的地方进行代码检查：
- 发现有几处生产消息的地方，message 发送出去时，内容是空的；
解决方式
- 将所有生产者 message 为空的地方作出修改，不允许消息为空还发出消息的情况;
本次异常引申出的一些问题
- 日志非常非常的大，本来服务器 180G 的磁盘空间，已经被占满了 152G
- 由于磁盘空间越来越少，导致其他服务器再发布时，无法发布成功
