RabbitMQ 整合 SpringCloud实战
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

rabbitmq-common 子项目
创建模块：rabbitmq-common

只需要建立一个实体类，不需要勾选其它东西

在这个模块里面建立一个 entity 包，在 entity 里面创建 order类

Order.java：

package com.dj.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;
}

}

common模块结构：

rabbitmq-springcloud-consumer 子项目
创建模块：rabbitmq-springcloud-consumer
和创建公共模块一样。

导入 pom 依赖：
