1. 生产者

1.1 引入maven依赖

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><groupId>com.itmayiedu</groupId><artifactId>springboot-p2p-roducer</artifactId><version>0.0.1-SNAPSHOT</version><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.0.1.RELEASE</version></parent><!-- 管理依赖 --><dependencyManagement><dependencies><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-dependencies</artifactId><version>Finchley.M7</version><type>pom</type><scope>import</scope></dependency></dependencies></dependencyManagement><dependencies><!-- SpringBoot整合Web组件 --><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><!-- SpringBoot Activemq --><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-activemq</artifactId></dependency><!-- https://mvnrepository.com/artifact/com.alibaba/fastjson --><dependency><groupId>com.alibaba</groupId><artifactId>fastjson</artifactId><version>1.2.49</version></dependency></dependencies><!-- 注意： 这里必须要添加， 否者各种依赖有问题 --><repositories><repository><id>spring-milestones</id><name>Spring Milestones</name><url>https://repo.spring.io/libs-milestone</url><snapshots><enabled>false</enabled></snapshots></repository></repositories></project>

1.2 application.yml配置

spring:activemq:###MQ连接通讯地址broker-url: tcp://127.0.0.1:61616###账号user: admin###密码 password: admin###自定义队列 my_queue: springboot2.0-queueserver:port: 8089

1.3 创建配置类ConfigQueue

@Component public class ConfigQueue {@Value("${my_queue}")private String myQueue;/*** 1.首先需要将队列注入springboot容器中** @return*/@Beanpublic Queue queue() {return new ActiveMQQueue(myQueue);}}

1.4 创建生产者类Producer

@Component public class Producer {@Autowiredprivate JmsMessagingTemplate jmsMessagingTemplate;@Autowiredprivate Queue queue;/*** 每隔5秒种时间向队列中发送消息*/@Scheduled(fixedDelay = 5000)public void send() {String userName = System.currentTimeMillis() + "";JSONObject jsonObject = new JSONObject();jsonObject.put("userName", userName);jsonObject.put("email", "apkdream@163.com");String msg = jsonObject.toJSONString();jmsMessagingTemplate.convertAndSend(queue, msg);System.out.println("采用点对点通讯模式,msg:" + msg);} }

1.5 启动类AppProducer

@SpringBootApplication @EnableScheduling public class AppProducer {public static void main(String[] args) {SpringApplication.run(AppProducer.class, args);}}

2. 消费者

2.1 引入maven依赖

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><groupId>com.itmayiedu</groupId><artifactId>springboot-p2p-consumer</artifactId><version>0.0.1-SNAPSHOT</version><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.0.1.RELEASE</version></parent><!-- 管理依赖 --><dependencyManagement><dependencies><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-dependencies</artifactId><version>Finchley.M7</version><type>pom</type><scope>import</scope></dependency></dependencies></dependencyManagement><dependencies><!-- SpringBoot整合Web组件 --><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><!-- SpringBoot Activemq --><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-activemq</artifactId></dependency><dependency><groupId>com.alibaba</groupId><artifactId>fastjson</artifactId><version>1.2.49</version></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-mail</artifactId></dependency><dependency><groupId>org.apache.commons</groupId><artifactId>commons-lang3</artifactId></dependency></dependencies><!-- 注意： 这里必须要添加， 否者各种依赖有问题 --><repositories><repository><id>spring-milestones</id><name>Spring Milestones</name><url>https://repo.spring.io/libs-milestone</url><snapshots><enabled>false</enabled></snapshots></repository></repositories> </project>

2.2 application.yml配置

spring:activemq:###MQ连接通讯地址broker-url: tcp://127.0.0.1:61616###账号user: admin###密码 password: adminmail:###163邮件服务host: smtp.163.com###发送邮件账号username: apkdream@163.com###pop协议授权码 password: xxxxxxenable: truesmtp:auth: truestarttls:enable: truerequired: true###自定义队列 my_queue: springboot2.0-queueserver:port: 8088

2.3 创建消费者类Consumer

import com.alibaba.fastjson.JSONObject; import org.apache.commons.lang3.StringUtils; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.jms.annotation.JmsListener; import org.springframework.mail.SimpleMailMessage; import org.springframework.mail.javamail.JavaMailSender; import org.springframework.stereotype.Component;/*** 消费者*/ @Component public class Consumer {@Autowiredprivate JavaMailSender javaMailSender;/*** 幂等性* @param msg* @throws Exception*/@JmsListener(destination = "${my_queue}")public void receive(String msg) throws Exception {if (StringUtils.isEmpty(msg)) {return;}/** 1.解析json **/JSONObject parseObject = JSONObject.parseObject(msg);String userName = parseObject.getString("userName");String email = parseObject.getString("email");sendSimpleMail(email, userName);System.out.println("采用点对点模式，消费者成功获取到生产者的消息,msg:" + msg);}public void sendSimpleMail(String eamil, String userName) throws Exception {SimpleMailMessage message = new SimpleMailMessage();/** 邮件来自 自己发自己 **/message.setFrom(eamil);/** 发送给谁 **/message.setTo(eamil);/** 邮件标题 **/message.setSubject("niceyoo 新邮件提醒");/** 邮件内容 **/message.setText("收到一批新的" + userName + "邮件!");/** 发送邮件 **/javaMailSender.send(message);System.out.println("邮件发送完成," + JSONObject.toJSONString(message));}}

2.4 启动类AppConsumer

@SpringBootApplication public class AppConsumer {public static void main(String[] args) {SpringApplication.run(AppConsumer.class, args);}}

3. 启动截图

3.1 生产者截图

3.2 消费者截图

3.3 ActiveMQ后台截图

Number Of Consumers  消费者 这个是消费者端的消费者数量 ;

Number Of Pending Messages 等待消费的消息 这个是当前未出队列的数量。可以理解为总接收数-总出队列数;

Messages Enqueued 进入队列的消息  进入队列的总数量,包括出队列的。 这个数量只增不减 ;

Messages Dequeued 出了队列的消息  可以理解为是消费这消费掉的数量 ;

3.4 邮件系统截图
