本篇内容介绍了“Springboot中如何整合Activemq”的有关知识,在实际案例的操作过程中,不少人都会遇到这样的困境,接下来就让小编带领大家学习一下如何处理这些情况吧!希望大家仔细阅读,能够学有所成!
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://127.0.0.1:61616spring.activemq.user=adminspring.activemq.password=adminserver.port=8080queue=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;@Configurationpublic 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;@Componentpublic 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@EnableSchedulingpublic 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;@Componentpublic 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:
