本文介绍了spring boot整合JMS(ActiveMQ实现)，分享给大家，也给自己留个学习笔记。

一、安装ActiveMQ

二、新建spring boot工程，并加入JMS(ActiveMQ)依赖

三、工程结构

pom依赖如下：

<?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

## 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 //如果此处设置为true，需要加如下的依赖包，否则会自动配置失败，报JmsMessagingTemplate注入失败

<dependency> 
      <groupId>org.apache.activemq</groupId> 
      <artifactId>activemq-pool</artifactId> 
      <!-- <version>5.7.0</version> --> 
    </dependency>

五、消息生产者

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

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

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：
