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：
