消息中间件系列教程（15） -RabbitMQ-基于全局消息ID解决幂等性问题

使用RabbitMQ的时候，同一个消息可能会被消费者多次消费，那么该如何解决呢？可以使用全局MessageID，解决幂等性的问题。基于《消息中间件系列教程（13） -RabbitMQ-SpringBoot集成RabbitMQ》的环境，下面直接上代码进行讲解：1.生产者，定...

RabbitMQ之幂等性问题处理

基本介绍消息消费时的幂等性（消息不被重复消费），同一个消息，第一次接收，正常处理业务，如果该消息第二次再接收，那就不能再处理业务，否则就处理重复了；幂等性：对于一个资源，不管你请求一次还是请求多次，对该资源本身造成的影响应该是相同...
