SpringBoot 简单集成ActiveMQ

ActiveMQ安装配置步骤见：https://www.cnblogs.com/vincenshen/p/10635362.html

第一步，pom.xml引入ActiveMQ依赖

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

第二步，application.properties中配置activemq

spring.activemq.broker-url=tcp://172.16.65.243:61616
spring.activemq.in-memory=true
spring.activemq.pool.enabled=false
spring.activemq.user=admin
spring.activemq.password=admin

第三步，Producer类编写

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jms.core.JmsMessagingTemplate;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;

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


@Component
public class Producer {

    @Autowired
    private JmsMessagingTemplate jmsMessagingTemplate;


    @Scheduled(fixedRate = 2000)　　// 使用定时任务，每两秒向mq中发送一个消息
    public void sendMsg(){
        Map<String, String> ptpMap = new HashMap<>();
        ptpMap.put("hello", "activeMQ");
        jmsMessagingTemplate.convertAndSend("ptp", ptpMap);
    }
}

第四步，Consumer编写

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

import java.util.Map;

@Component
public class Consumer {

    @JmsListener(destination = "ptp")　　// 通过JmsListerner实时获取mq中的消息
    public void readMsg(Map map){
        System.out.println("currentTimeMillis" + System.currentTimeMillis() + "::ptp = [" + map + "]");
    }
}

第五步，测试效果

  .   ____          _            __ _ _
 /\ / ___'_ __ _ _(_)_ __  __ _    
( ( )\___ | '_ | '_| | '_ / _` |    
 \/  ___)| |_)| | | | | || (_| |  ) ) ) )
  '  |____| .__|_| |_|_| |_\__, | / / / /
 =========|_|==============|___/=/_/_/_/
