篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了ActivemMQ之消息服务器平台（发邮件）相关的知识，希望对你有一定的参考价值。

消息服务平台处理公司内部各种消息业务

比如发送邮件发送短信微信推送

接口有两种类型异步同步

同步需求：当调用消息服务平台，需要返回消息服务平台调用第三方平台接口是否成功

异步需求：采用MQ异步发送消息（没有返回结果）

我用world画了个示意图：大家看下

发送邮件参数：

邮件账号内容信息

格式是JSON

需要使用 fastJson：

	     <!--fastjson -->
		<dependency>
			<groupId>com.alibaba</groupId>
			<artifactId>fastjson</artifactId>
			<version>1.2.49</version>
		</dependency>

存入消息：消息参数格式是Json 所以需要 fastjson

package com.toov5.Producer;

import javax.jms.Queue;

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 com.alibaba.fastjson.JSONObject;

@Component
public class P2PProducer {
    @Autowired
    private JmsMessagingTemplate jmsMessagingTemplate;
    //把队列注入进来 
    @Autowired  //此注解默认是以类型找  在配置文件中 已经注入的  @Bean 
    private Queue queue;
    
    //每隔5s时间向队列发送消息
    @Scheduled(fixedDelay=5000)  //每间隔2s向队列发送消息
    public void send() {
        String userName = System.currentTimeMillis()+" ";
            JSONObject jsonObject  = new JSONObject();
            jsonObject.put("username", userName);
            jsonObject.put("email", "acmgogo@163.com");
            String msgString = jsonObject.toJSONString();
        jmsMessagingTemplate.convertAndSend(queue,msgString);
        System.out.println("点对点通讯，msg"+msgString);
    }
}

主要的依赖：

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

　注意163邮件需要开通pop3协议！　

其他遵循之前点对点demo

package com.toov5.Producer;

import javax.jms.Queue;

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 com.alibaba.fastjson.JSONObject;

@Component
public class P2PProducer {
    @Autowired
    private JmsMessagingTemplate jmsMessagingTemplate;
    //把队列注入进来 
    @Autowired  //此注解默认是以类型找  在配置文件中 已经注入的  @Bean 
    private Queue queue;
    
    //每隔5s时间向队列发送消息
    @Scheduled(fixedDelay=5000)  //每间隔2s向队列发送消息
    public void send() {
        String userName = System.currentTimeMillis()+" ";
            JSONObject jsonObject  = new JSONObject();
            jsonObject.put("username", userName);
            jsonObject.put("email", "acmtest@163.com");
            String msgString = jsonObject.toJSONString();
             jmsMessagingTemplate.convertAndSend(queue,msgString);
        System.out.println("点对点通讯，msg"+msgString);
    }
}

配置：

package com.toov5.config;

import javax.jms.Queue;

import org.apache.activemq.command.ActiveMQQueue;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.stereotype.Component;

@Component
public class ConfigQueue {
   @Value("${my_queue}")
   private String myQueue;
    
    //首先将队列注入到SpringBoot容器中去
    @Bean
    public Queue queue() {
        return new ActiveMQQueue(myQueue); 
    } 
    
}

启动：

package com.toov5;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.scheduling.annotation.EnableScheduling;

@SpringBootApplication
@EnableScheduling  //开启定时任务
public class AppProducer {
   public static void main(String[] args) {
    SpringApplication.run(AppProducer.class, args);
}
}

先启动consumer！
