spring boot整合JMS(ActiveMQ实现)

pom依赖如下：

</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：

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！
