1、在pom文件中引入对应jar包
<!--activeMQ start--> <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> <dependency> <groupId>org.apache.activemq</groupId> <artifactId>activemq-pool</artifactId> <!-- <version>5.7.0</version> --> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>5.0.7.RELEASE</version> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.12</version> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-test</artifactId> <version>2.0.3.RELEASE</version> </dependency> <!--activeMQ end-->
2、application.yml文件配置activemq;对于监听Listener使用注解的形式
#activeMQ的配置 activemq: broker-url: tcp://localhost:61616 in-memory: true 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
3、创建生产者类,生产者代码如下:
/** * Created by Administrator on 2018/7/27. */ @RunWith(SpringRunner.class) @SpringBootTest public class SpringbootJmsApplicationTests { @Test public void contextLoads() throws InterruptedException, JMSException { Destination destination = new ActiveMQQueue("queue_demo"); //创建与JMS服务的连接:ConnectionFactory被管理的对象,由客户端创建,用来创建一个连接对象 ConnectionFactory connectionfactory = new ActiveMQConnectionFactory("tcp://localhost:61616"); //获取连接,connection一个到JMS系统提供者的活动连接 javax.jms.Connection connection = connectionfactory.createConnection(); //打开会话,一个单独的发送和接受消息的线程上下文 Session session =connection.createSession(false,Session.AUTO_ACKNOWLEDGE ); Queue queue = new ActiveMQQueue("queue_demo"); MessageProducer msgProducer = session.createProducer(queue); Message msg = session.createTextMessage("文本1"); msgProducer.send(msg); System.out.println("文本消息已发送"); } }
4、编写消费者代码,代码如下:
/** * Created by Administrator on 2018/7/27. */ @Component public class Consumer2 { // 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 = "queue_es") public void receiveQueue(String mapStr) { System.out.println("接受的消息:"+mapStr); } }
5、运行生产者(本处是test注解的测试代码),直接运行,结果如下
发送端:
接收端:
ps:如果想设置为独占消息消费模式,只需将消费者的代码@JmsListener注解处修改为如下代码:
@JmsListener(destination = "queue_es?consumer.exclusive=true")
就可以设置此消费者为独占消息消费模式,队列里的任务会玩先后顺序被这个消费者处理掉
