Spring Boot整合JMS

Spring Boot整合JMS

1. 首先在Linux安装好ActiveMQ，再启动ActiveMQ。
2. 创建Spring Boot项目

• 添加依赖

 <dependencies>
        <dependency>
            <groupId>org.springframework.bootgroupId>
            <artifactId>spring-boot-starter-activemqartifactId>
        dependency>
        <dependency>
            <groupId>org.springframework.bootgroupId>
            <artifactId>spring-boot-starter-webartifactId>
        dependency>

        <dependency>
            <groupId>org.springframework.bootgroupId>
            <artifactId>spring-boot-starter-testartifactId>
            <scope>testscope>
            <exclusions>
                <exclusion>
                    <groupId>org.junit.vintagegroupId>
                    <artifactId>junit-vintage-engineartifactId>
                exclusion>
            exclusions>
        dependency>
    dependencies>

• 配置连接信息

spring.activemq.broker-url=tcp://192.168.2.128:61616
spring.activemq.packages.trust-all=true
spring.activemq.user=admin
spring.activemq.password=admin

• 在项目中配置一个消息队列Bean，该Bean得实例就由ActiveMQ提供

@SpringBootApplication
public class JmsApplication {

    public static void main(String[] args) {
        SpringApplication.run(JmsApplication.class, args);
    }

    @Bean
    Queue queue(){
        return  new ActiveMQQueue("amq");
    }
}

• 创建一个JMS组件来完成消息的发送和接收

@Component
public class JmsComponent {
    @Autowired
    JmsMessagingTemplate jmsMessagingTemplate;
    
    //注入自定义的ActiveMQ
    @Autowired
    Queue queue;

    public void send(Message msg){
        jmsMessagingTemplate.convertAndSend(this.queue,msg);
    }

    //指明消费者接收的消息为amq
    @JmsListener(destination = "amq")
    public void receive(Message msg){
        System.out.println("receive:"+msg);
    }
}

public class Message implements Serializable {
    private String content;
    private Date date;
 
} 

• 测试

@SpringBootTest
class JmsApplicationTests {

    @Autowired
    JmsComponent jmsComponent;

    @Test
    void contextLoads() {
        Message message = new Message();
        message.setContent("youyuan");
        message.setDate(new Date());
        jmsComponent.send(message);
    }

}
