Springboot+Activemq整合
1 导入整合所需要的依赖:
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-activemq</artifactId> </dependency>
2 创建application.properties文件
spring.activemq.broker-url=tcp://127.0.0.1:61616 spring.activemq.user=admin spring.activemq.password=admin server.port=8080 queue=myqueue
3.自定义配置文件QueueConfig 读取配置文件的队列名,根据队列名字创建一个Queue
package com.example.demo; import javax.jms.Queue; import org.apache.activemq.ActiveMQConnectionFactory; import org.apache.activemq.command.ActiveMQQueue; import org.springframework.beans.factory.annotation.Value; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.jms.config.DefaultJmsListenerContainerFactory; import org.springframework.jms.core.JmsTemplate; @Configuration public class QueueConfig { @Value("${queue}") private String queue; @Bean public Queue logQueue() { return new ActiveMQQueue(queue); }}
4.创建生产者,可以直接使用提供的模板JmsMessagingTemplate 进行消息的发送:
package com.example.demo.producter; import javax.jms.Queue; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.jms.core.JmsMessagingTemplate; import org.springframework.stereotype.Component; import com.example.demo.SpringbootActivemqApplication; @Component public class Producter { @Autowired private JmsMessagingTemplate jmsMessagingTemplate; @Autowired private Queue queue; private static Logger logger = LoggerFactory.getLogger( Producter .class); public void send() { String str = "生产者生产数据:" + System.currentTimeMillis(); jmsMessagingTemplate.convertAndSend(queue, str); logger.info("生产者数据:{}", str); } }
5.启动类:
package com.example.demo; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.context.ApplicationListener; import org.springframework.context.event.ContextRefreshedEvent; import org.springframework.scheduling.annotation.EnableScheduling; import com.example.demo.producter.Producter; import com.example.demo.producter.consumer.Consumer; @SpringBootApplication @EnableScheduling public class SpringbootActivemqApplication implements ApplicationListener<ContextRefreshedEvent> { @Autowired public Producter producter; @Autowired public Consumer consumer; public static void main(String[] args) { SpringApplication.run(SpringbootActivemqApplication.class, args); //onApplicationEvent方法 在启动springboot的时候 会运行该方法,可根据项目实际情况 选择合适调用消息发送方法 } @Override public void onApplicationEvent(ContextRefreshedEvent event) { producter.send(); } }
6.启动项目,控制台输出内容:
7.创建消费者,创建消费者比较容易,只需要监听队列就可以:
package com.example.demo.producter.consumer; import org.springframework.jms.annotation.JmsListener; import org.springframework.stereotype.Component; @Component public class Consumer { @JmsListener(destination = "${queue}") public void receive(String msg) { System.out.println("监听器收到msg:" + msg); } }
8.最后结果:
加载全部内容
