RabbitMQ整合 SpringCloud

RabbitMQ整合 SpringCloud

注意一点，在发送消息的时候对template进行配置mandatory=true保证监听有效

生产端还可以配置其他属性，比如发送重试，超时时间、次数、间隔等

消费端核心配置

首先配置手工确认模式，用于ACK的手工处理，这样我们可以保证消息的可靠性送达，或者在消费端消费失败的时候可以做到重回队列、根据业务记录日志等处理

可以设置消费端的监听个数和最大个数，用于控制消费端的并发情况

@RabbitListener注解的使用

消费端监听@RabbitListener注解，这个对于在实际工作中非常的好用

@RabbitListener是一个组合注解，里面可以注解配置（@QueueBinding、@Queue、@Exchange）直接通过这个组合注解一次性搞定消费端交换机、队列、绑定、路由、并且配置监听功能等
