SpringBoot整合ActiveMQ的p2p模式(一)
1.安装ActiveMQ
官网下载地址:http://activemq.apache.org/download.html
(1)在Windows上在解压后有个bin下有win64,win64目录下有个activemq.bat,双击activemq.bat启动


(3)输入用户名:admin 密码:admin

(4)看到ActiveMQ这就启动成功了
p2p的过程则理解起来更加简单。它好比是两个人打电话,这两个人是独享这一条通信链路的。一方发送消息,另外一方接收,就这么简单。在实际应用中因为有多个用户对使用p2p的链路。
2.SpringBoot整合ActiveMQ
(1)这是我的项目结构

(2)pom.xml完整的文件
<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.qingfeng</groupId> <artifactId>springboot-ActiveMQ</artifactId> <version>0.0.1-SNAPSHOT</version> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.1.1.RELEASE</version> <relativePath /> <!-- lookup parent from repository --> </parent> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> <java.version>1.8</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-activemq</artifactId> </dependency> <!-- 热部署 --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-devtools</artifactId> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project>
(3)application.properties文件配置
server.port=8088 server.servlet.context-path=/springboot-ActiveMQ/ #不能用127.0.0.1,不然会报错 #spring.activemq.broker-url=tcp://127.0.0.1:61616 spring.activemq.broker-url=tcp://localhost:61616 spring.activemq.in-memory=true spring.activemq.pool.enabled=false
(4)SpringBoot启动类
package com.qingfeng;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class AppStart {
public static void main(String[] args) {
SpringApplication.run(AppStart.class, args);
}
}
(5)生产者Producer类
package com.qingfeng.producer;
import java.util.Map;
import javax.jms.Destination;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jms.core.JmsMessagingTemplate;
import org.springframework.stereotype.Service;
/**
*生产者
*/
@Service
public class Producer {
// 也可以注入JmsTemplate,JmsMessagingTemplate对JmsTemplate进行了封装
@Autowired
private JmsMessagingTemplate jmsMessagingTemplate;
// 发送消息,destination是发送到的队列名称,message是待发送的消息
public void sendMessage(Destination destination, String message){
jmsMessagingTemplate.convertAndSend(destination, message);
}
// 发送消息,destination是发送到的队列名称,map类型的发送的消息
public void sendMapMessage(Destination destination, Map<String ,String> map){
jmsMessagingTemplate.convertAndSend(destination, map);
}
}
(6)消费者Consumer类
package com.qingfeng.consumer;
import java.util.Map;
import org.springframework.jms.annotation.JmsListener;
import org.springframework.stereotype.Component;
/**
*消费者
*/
@Component
public class Consumer {
// 使用JmsListener配置消费者监听的队列名称qingfeng.queue,其中text是接收到的消息
@JmsListener(destination = "qingfeng-queue")
public void receiveQueue(String text) {
System.out.println("Consumer收到的生产者的报文为:"+text);
}
// 使用JmsListener配置消费者监听的队列名称qingfeng-map-queue,其中map是接收到的消息
@JmsListener(destination = "qingfeng-map-queue")
public void receiveMapQueue(Map<String ,String> map) {
System.out.println("Consumer收到的生产者map类型的报文为:"+map);
}
}
(7)测试类TestController类
package com.qingfeng.controller;
import java.util.HashMap;
import java.util.Map;
import javax.jms.Destination;
import org.apache.activemq.command.ActiveMQQueue;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
import com.qingfeng.producer.Producer;
@RestController
public class TestController {
@Autowired
private Producer producer;
// http://localhost:8088/springboot-ActiveMQ/send?text=qingfeng
@GetMapping("send")
public String send(String text){
//创建一个队列名称为qingfeng-queue
Destination destination = new ActiveMQQueue("qingfeng-queue");
//调用生产者产生消息
producer.sendMessage(destination, text);
return "发送成功";
}
// http://localhost:8088/springboot-ActiveMQ/sendMap
@GetMapping("sendMap")
public String sendMap(){
//创建一个队列名称为qingfeng-map-queue
Destination destination = new ActiveMQQueue("qingfeng-map-queue");
HashMap<String, String> map = new HashMap<>();
map.put("name", "qingfeng");
map.put("age", "18");
map.put("QQ", "37942135");
//调用生产者产生消息
producer.sendMapMessage(destination, map);
return "发送成功";
}
}
(8)启动项目AppStart类
测试:http://localhost:8088/springboot-ActiveMQ/send?text=qingfeng

(9)在控制台上输出

(10)测试:http://localhost:8088/springboot-ActiveMQ/sendMap

(10)在控制台上输出

(11)可以看到activemq就多了两个qingfeng-queue队列和qingfeng-map-queue队列了

SpringBoot整合activemq就完成了。
