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

测试代码：

RabbitmqSpringcloudProducerApplicationTests

package com.javaxh.rabbitmqspringcloudproducer;
import com.javaxh.rabbitmqcommon.entity.Order;
import com.javaxh.rabbitmqspringcloudproducer.producer.RabbitSender;
import org.junit.jupiter.api.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.HashMap;
import java.util.Map;

@RunWith(SpringRunner.class)
@SpringBootTest
class RabbitmqSpringcloudProducerApplicationTests {

    @Autowired
    private RabbitSender rabbitSender;

    private static SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS");

    @Test
    public void testSender1() throws Exception {
        Map<String, Object> properties = new HashMap<>();
        properties.put("number", "12345");
        properties.put("send_time", simpleDateFormat.format(new Date()));
        rabbitSender.send("Hello RabbitMQ For Spring Boot!", properties);
    }

    @Test
    public void testSender2() throws Exception {
        Order order = new Order("001", "第一个订单");
        rabbitSender.sendOrder(order);
    }

}

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：
