今天就来康康spring怎么整合RabbitMQ
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
注：由于类配置写在代码里非常不友好，所以强烈建议大家使用配置文件配置
创建一个
rabbitmq-common通用模板项目
放公用实体类
package com.javaxh.rabbitmqcommon.entity; import java.io.Serializable; public class Order implements Serializable { private String id; private String name; public Order() { } public Order(String id, String name) { super(); this.id = id; this.name = name; } public String getId() { return id; } public void setId(String id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } }
创建
rabbitmq-springcloud-consumer子项目

运行效果：
启动consumer项目，然后在运行测试类中的方法
运行公用模板类传送一个实体类给方法：
