1、启动activemq，并进入MQ的消息队列

2、在pom.xml中添加依赖包

<dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-activemq</artifactId>
            </dependency>
            <dependency>
                <groupId>com.alibaba</groupId>
                <artifactId>fastjson</artifactId>
                <version>1.2.30</version>
            </dependency>

3、创建全局配置文件（application.properties）

spring.activemq.broker-url=tcp://localhost:61616
    spring.activemq.user=admin
    spring.activemq.password=admin
    spring.activemq.in-memory=true
    spring.activemq.pool.enabled=false

4、创建测试类（UserController.java）

package com.jeff.controller;
    
    import com.alibaba.fastjson.JSONObject;
    import org.apache.activemq.command.ActiveMQQueue;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.jms.core.JmsMessagingTemplate;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    
    import javax.jms.Destination;
    
    @RestController
    @RequestMapping("user")
    public class UserController { 
    
        @Autowired
        private JmsMessagingTemplate jmsTemplate;
    
        @RequestMapping("register")
        public Object register() { 
    
            JSONObject json = new JSONObject();
            json.put("loginName", "Jeff");
            json.put("email", "123456@163.com");
            send("jeff_queue", json.toJSONString());
    
            return "success";
        }
    
        public void send(String queue_name, String json) { 
            Destination destination = new ActiveMQQueue(queue_name);
            jmsTemplate.convertAndSend(destination, json);
        }
    
    }

5、启动springboot项目，并访问http://localhost:8080/user/register

6、查看MQ的消息队列
