springboot整合activiMQ

首先说明：

队列queue  的特点就是，许多人可以监听它，但是只有一个人能够收到消息。 
主题topic    的特点就是，许多人监听它，都能收到消息。

需要安装activiMQ在自己的电脑上。启动方法 在bin目录   activemq start   即可

访问activiMQ在浏览器输入 ：http://localhost:8161

创建一个springboot的项目

说明：这里url的访问协议和路径要注意一下。

发送者

package cn.lzh.demo;

import java.util.HashMap;
import java.util.Map;

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;
/**
 * 消息生产者
 * @author Administrator
 *
 */
@RestController
public class QueueController {

    @Autowired
    private JmsMessagingTemplate jmsMessagingTemplate;

    @RequestMapping("/send")
    public void send(String text){

        jmsMessagingTemplate.convertAndSend("A1", text);
    }

    @RequestMapping("/sendmap")
    public void sendMap(){
        Map map=new HashMap<>();
        map.put("mobile", "13683391759");
        map.put("template_code", "SMS_86640114");
        map.put("sign_name","卡卡罗特");
        map.put("param", "{\"name\":\"小刘\"}");

        jmsMessagingTemplate.convertAndSend("A2", map);
    }
}

消费者

package cn.lzh.demo;

import java.util.Map;

import org.springframework.jms.annotation.JmsListener;
import org.springframework.stereotype.Component;

@Component
public class Consumer {

    @JmsListener(destination="A1")
    public void readMessage(String text){
        System.out.println("接收到消息:"+text);
    }

    @JmsListener(destination="A2")
    public void readMapMessage(Map map){
        System.out.println(map);
    }

}

简单的要死简直！！！
