ActiveMQ之消息服务器平台【发邮件】

桃扇骨 2022-12-08 04:27 187阅读 0赞

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

![cefa35a5a8d77179c80c002d65c2d57e.png][]

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

![d052a978ab25841fc4745a7c5e1c6f48.png][]

发送邮件参数：

邮件账号 内容信息

格式是JSON

需要使用 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：

    }
    }
