添加jar包依赖
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-activemq</artifactId> </dependency> <!--消息队列连接池--> <dependency> <groupId>org.apache.activemq</groupId> <artifactId>activemq-pool</artifactId> <version>5.15.0</version> </dependency>
添加spring boot配置
spring.activemq.broker-url=tcp://192.168.1.133:61616
spring.activemq.user=admin
spring.activemq.password=admin
#默认情况下activemq提供的是queue模式,若要使用topic模式需要配置下面配置
spring.jms.pub-sub-domain=true
创建ActiveMQ配置类
@Configuration @EnableJms public class JmsConfig { private static final String QUEUE_NAME = "active.queue"; private static final String TOPIC_NAME = "active.topic"; @Bean public Queue queue(){ return new ActiveMQQueue(QUEUE_NAME); } @Bean public Topic topic(){ return new ActiveMQTopic(TOPIC_NAME); } }
一对一(队列):发送的消息只能由一个消费者接收
//提供者 @Component public class ActiveMQQueueProducer { @Autowired private JmsMessagingTemplate jmsMessagingTemplate; @Autowired private Queue queue; public void sendQueueMsg(String msg) { this.jmsMessagingTemplate.convertAndSend(this.queue, msg); } } //消费者 ckage org.huqi.config; import org.springframework.context.annotation.Configuration; import org.springframework.jms.annotation.JmsListener; import javax.jms.TextMessage; @Configuration public class Que_comsumer { @JmsListener(destination = "active.queue") public void recive(TextMessage msg) throws Exception{ System.out.print(msg.getText().toString()); } }
发布订阅:及时接收,如果超过时候后就无法接收到消息
//提供者 @Component public class ActiveMQTopicPublisher { @Autowired private JmsMessagingTemplate jmsMessagingTemplate; @Autowired private Topic topic; public void sendTopicMsg(String msg) { System.out.println("发布信息:" + msg); this.jmsMessagingTemplate.convertAndSend(this.topic, msg); } } //消费者 @Component public class ActiveMQTopicSubscriber { /** * 监听和读取topic消息 * @param message */ @JmsListener(destination = "active.topic") public void readActiveTopic(String message) { System.out.println("接受到:" + message); } }
ActiveMQ无法写入对象解决,在spring boot配置文件中添加配置
#将所有对象都加入jsm白名单中 #允许所有包写入 spring.activemq.packages.trust-all=true #指定包中的类加入白名单 spring.activemq.packages.trusted=org.huqi.bean
