## 1.坐标 ##

<dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-activemq</artifactId>
                <version>2.0.4.RELEASE</version>
            </dependency>

## 2. 配置 ##

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

## 3.1 生产者 ##

![在这里插入图片描述][70 1]  
LoginProducer代码：

package com.czxy.mq.producer;
    
    import org.apache.activemq.command.ActiveMQMapMessage;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.jms.core.JmsMessagingTemplate;
    import org.springframework.stereotype.Service;
    
    import javax.jms.Destination;
    
    /** * @author Fang * @create 2018-10-20 18:19 * @desc 生产者 **/
    @Service
    public class LoginProducer { 
        @Autowired
        private JmsMessagingTemplate template;
    
        public void sendMessage(Destination destination, ActiveMQMapMessage message){ 
            System.out.println("已成功生产消息");
            template.convertAndSend(destination,message);
    
        }
    }

## 3.2 放入消息队列里： ##

UserService（业务逻辑层代码）

package com.czxy.service.impl;
    
    import com.czxy.dao.TUserMapper;
    import com.czxy.domain.TUser;
    import com.czxy.mq.producer.LoginProducer;
    import com.czxy.service.UserService;
    import org.apache.activemq.command.ActiveMQMapMessage;
    import org.apache.activemq.command.ActiveMQQueue;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Service;
    import org.springframework.transaction.annotation.Transactional;
    
    import javax.jms.JMSException;
    
    /** * @author Fang * @create 2018-10-20 18:10 * @desc 业务层实现类 **/
    @Service
    @Transactional
    public class UserServiceImpl implements UserService { 
        @Autowired
        private LoginProducer loginProducer;
    
        @Autowired
        private TUserMapper tUserMapper;
        /** *@author Fang *@create 2018/10/20 18:12 *@desc 一个简单的登录方法（不在乎业务 主要在意发送mq） **/
        public boolean doLogin(TUser user, String ip) { 
    
            try { 
                //放入消息队列
                ActiveMQMapMessage message = new ActiveMQMapMessage();
                message.setString("name","张三");
                loginProducer.sendMessage(new ActiveMQQueue("user.log"),message);
                
    
            } catch (JMSException e) { 
                e.printStackTrace();
            }
    
            return true;
        }
    }

## 3.3消费者 ##

![在这里插入图片描述][70 3]

LoginConsumer代码

package com.czxy.mq.consumer;
    
    import org.apache.activemq.command.ActiveMQMapMessage;
    import org.springframework.jms.annotation.JmsListener;
    import org.springframework.stereotype.Component;
    
    import javax.jms.JMSException;
    
    /** * @author Fang * @create 2018-10-20 18:22 * @desc 消费者 **/
    @Component
    public class LoginConsumer { 
    
        @JmsListener(destination = "user.log")
        public void loginUser(ActiveMQMapMessage message){ 
            try { 
                String name = message.getString("name");
                System.out.println(name);
                System.out.println("已消费");
            } catch (JMSException e) { 
                e.printStackTrace();
            }
        }
    }
