一、安装ActiveMQ
具体的安装步骤,请参考我的另一篇博文:
http://blog.csdn.net/liuchuanhong1/article/details/52057711
二、新建spring boot工程,并加入JMS(ActiveMQ)依赖
三、工程结构
pom依赖如下:
[html] view plain copy
- <?xml version="1.0" encoding="UTF-8"?>
- <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.chhliu.springboot.jms</groupId>
- <artifactId>springboot-jms</artifactId>
- <version>0.0.1-SNAPSHOT</version>
- <packaging>jar</packaging>
- <name>springboot-jms</name>
- <description>Demo project for Spring Boot Jms</description>
- <parent>
- <groupId>org.springframework.boot</groupId>
- <artifactId>spring-boot-starter-parent</artifactId>
- <version>1.4.3.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>1.7</java.version>
- </properties>
- <dependencies>
- <dependency>
- <groupId>org.springframework.boot</groupId>
- <artifactId>spring-boot-starter-activemq</artifactId>
- </dependency>
- <dependency>
- <groupId>org.springframework.boot</groupId>
- <artifactId>spring-boot-starter-test</artifactId>
- <scope>test</scope>
- </dependency>
- </dependencies>
- <build>
- <plugins>
- <plugin>
- <groupId>org.springframework.boot</groupId>
- <artifactId>spring-boot-maven-plugin</artifactId>
- </plugin>
- </plugins>
- </build>
- </project>
四、修改application.properties配置文件
[java] view plain copy
- ## URL of the ActiveMQ broker. Auto-generated by default. For instance `tcp://localhost:61616`
- # failover:(tcp://localhost:61616,tcp://localhost:61617)
- # tcp://localhost:61616
- spring.activemq.broker-url=tcp://localhost:61616
- spring.activemq.in-memory=true
- spring.activemq.pool.enabled=false
五、消息生产者
[java] view plain copy
- package com.chhliu.springboot.jms;
- import javax.jms.Destination;
- import org.springframework.beans.factory.annotation.Autowired;
- import org.springframework.jms.core.JmsMessagingTemplate;
- import org.springframework.stereotype.Service;
- @Service("producer")
- public class Producer {
- @Autowired // 也可以注入JmsTemplate,JmsMessagingTemplate对JmsTemplate进行了封装
- private JmsMessagingTemplate jmsTemplate;
- // 发送消息,destination是发送到的队列,message是待发送的消息
- public void sendMessage(Destination destination, final String message){
- jmsTemplate.convertAndSend(destination, message);
- }
- }
六、消息消费者
[java] view plain copy
- package com.chhliu.springboot.jms;
- import org.springframework.jms.annotation.JmsListener;
- import org.springframework.stereotype.Component;
- @Component
- public class Consumer {
- // 使用JmsListener配置消费者监听的队列,其中text是接收到的消息
- @JmsListener(destination = "mytest.queue")
- public void receiveQueue(String text) {
- System.out.println("Consumer收到的报文为:"+text);
- }
- }
消费者2的代码同上,注意,消息消费者的类上必须加上@Component,或者是@Service,这样的话,消息消费者类就会被委派给Listener类,原理类似于使用SessionAwareMessageListener以及MessageListenerAdapter来实现消息驱动POJO
七、测试
[java] view plain copy
- package com.chhliu.springboot.jms;
- import javax.jms.Destination;
- import org.apache.activemq.command.ActiveMQQueue;
- import org.junit.Test;
- import org.junit.runner.RunWith;
- import org.springframework.beans.factory.annotation.Autowired;
- import org.springframework.boot.test.context.SpringBootTest;
- import org.springframework.test.context.junit4.SpringRunner;
- @RunWith(SpringRunner.class)
- @SpringBootTest
- public class SpringbootJmsApplicationTests {
- @Autowired
- private Producer producer;
- @Test
- public void contextLoads() throws InterruptedException {
- Destination destination = new ActiveMQQueue("mytest.queue");
- for(int i=0; i<100; i++){
- producer.sendMessage(destination, "myname is chhliu!!!");
- }
- }
- }
测试结果如下:
[java] view plain copy
- Consumer2收到的报文为:myname is chhliu!!!
- Consumer收到的报文为:myname is chhliu!!!
- Consumer2收到的报文为:myname is chhliu!!!
- Consumer收到的报文为:myname is chhliu!!!
- Consumer2收到的报文为:myname is chhliu!!!
- Consumer收到的报文为:myname is chhliu!!!
- Consumer2收到的报文为:myname is chhliu!!!
- Consumer收到的报文为:myname is chhliu!!!
- Consumer2收到的报文为:myname is chhliu!!!
- Consumer收到的报文为:myname is chhliu!!!
- Consumer2收到的报文为:myname is chhliu!!!
- Consumer收到的报文为:myname is chhliu!!!
- Consumer2收到的报文为:myname is chhliu!!!
经过上面的几个步骤,spring boot和Jms就基本上整合完成了,是不是使用起来很方便了!
八、实现双向队列
1、下面首先来对Consumer2这个消费者来进行下改造,代码如下:
[java] view plain copy
- package com.chhliu.springboot.jms;
- import org.springframework.jms.annotation.JmsListener;
- import org.springframework.messaging.handler.annotation.SendTo;
- import org.springframework.stereotype.Component;
- @Component
- public class Consumer2 {
- @JmsListener(destination = "mytest.queue")
- @SendTo("out.queue")
- public String receiveQueue(String text) {
- System.out.println("Consumer2收到的报文为:"+text);
- return "return message"+text;
- }
- }
从上面的代码可以看出,我们在receiveQueue方法上面多加了一个注解@SendTo("out.queue"),该注解的意思是将return回的值,再发送的"out.queue"队列中,下面我们再来跑一下前面的测试,在监控页面中,我们发现,"out.queue"队列中已经有内容了,如下:
进入Browse界面观看:
最后看下收到的具体信息:
我们发现,该队列中的消息,就是我们返回的值!
九、对Producer进行改造
通过上面的示例,我们现在对Producer进行改造,使其既能生产报文,又能消费队列中的报文,代码如下:
[java] view plain copy
- package com.chhliu.springboot.jms;
- import javax.jms.Destination;
- import org.springframework.beans.factory.annotation.Autowired;
- import org.springframework.jms.annotation.JmsListener;
- import org.springframework.jms.core.JmsMessagingTemplate;
- import org.springframework.stereotype.Service;
- @Service("producer")
- public class Producer {
- @Autowired
- private JmsMessagingTemplate jmsTemplate;
- public void sendMessage(Destination destination, final String message){
- jmsTemplate.convertAndSend(destination, message);
- }
- @JmsListener(destination="out.queue")
- public void consumerMessage(String text){
- System.out.println("从out.queue队列收到的回复报文为:"+text);
- }
- }
测试结果如下:
[java] view plain copy
- 从out.queue队列收到的回复报文为:return messagemyname is chhliu!!!
- Consumer收到的报文为:myname is chhliu!!!
- Consumer2收到的报文为:myname is chhliu!!!
- 从out.queue队列收到的回复报文为:return messagemyname is chhliu!!!
- Consumer收到的报文为:myname is chhliu!!!
- Consumer2收到的报文为:myname is chhliu!!!
- 从out.queue队列收到的回复报文为:return messagemyname is chhliu!!!
- Consumer收到的报文为:myname is chhliu!!!
- Consumer2收到的报文为:myname is chhliu!!!
- 从out.queue队列收到的回复报文为:return messagemyname is chhliu!!!
