springboot整合activemq

不罗嗦直接上代码结构与工程目录:

这个是主工程目录:

                </plugin>
            </plugins>
        </pluginManagement>
    </build>
</project>

接下来是代码:

消费者和生产者代码是配置一样的

package com.cxy.config;


import org.apache.activemq.ActiveMQConnectionFactory;
import org.apache.activemq.command.ActiveMQQueue;
import org.apache.activemq.command.ActiveMQTopic;
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.config.JmsListenerContainerFactory;

import javax.jms.Queue;
import javax.jms.Topic;

@Configuration
public class ActiveMQConfig {
    @Value("${queueName}")
    private String queueName;

    @Value("${topicName}")
    private String topicName;

    @Value("${spring.activemq.user}")
    private String usrName;

    @Value("${spring.activemq.password}")
    private  String password;

    @Value("${spring.activemq.broker-url}")
    private  String brokerUrl;

    @Bean
    public Queue queue(){
        return new ActiveMQQueue(queueName);
    }

    @Bean
    public Topic topic(){
        return new ActiveMQTopic(topicName);
    }

    @Bean
    public ActiveMQConnectionFactory connectionFactory() {
        return new ActiveMQConnectionFactory(usrName, password, brokerUrl);
    }

    @Bean
    public JmsListenerContainerFactory<?> jmsListenerContainerQueue(ActiveMQConnectionFactory connectionFactory){
        DefaultJmsListenerContainerFactory bean = new DefaultJmsListenerContainerFactory();
        bean.setConnectionFactory(connectionFactory);
        return bean;
    }

    @Bean
    public JmsListenerContainerFactory<?> jmsListenerContainerTopic(ActiveMQConnectionFactory connectionFactory){
        DefaultJmsListenerContainerFactory bean = new DefaultJmsListenerContainerFactory();
        //设置为发布订阅方式, 默认情况下使用的生产消费者方式
        bean.setPubSubDomain(true);
        bean.setConnectionFactory(connectionFactory);
        return bean;
    }
}

yml的配置 也是一样的,只需要改下启动端口:

server:
  port: 8080
spring:
  activemq:
    user: admin
    password: admin
    broker-url: tcp://127.0.0.1:61616
    pool:
      enabled: true
      max-connections: 10

queueName: publish.queue
topicName: publish.topic

生成者文件:

package com.cxy.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jms.annotation.JmsListener;
import org.springframework.jms.core.JmsMessagingTemplate;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import javax.jms.Queue;
import javax.jms.Topic;

@RestController
@RequestMapping("/publish")
public class PublishController {
    @Autowired
    private JmsMessagingTemplate jms;

    @Autowired
    private Queue queue;

    @Autowired
    private Topic topic;

    @RequestMapping("/queue")
    public String queue(){

        for (int i = 0; i < 1000 ; i++){
            jms.convertAndSend(queue, "queue"+i);
        }

        return "queue 发送成功";
    }

    @JmsListener(destination = "out.queue")
    public void consumerMsg(String msg){
        System.out.println(msg);
    }

    @RequestMapping("/topic")
    public String topic(){

        for (int i = 0; i < 100 ; i++){
            jms.convertAndSend(topic, "topic"+i);
        }

        return "topic 发送成功";
    }
}

消费者监听代码:

package com.cxy.listener;

import org.springframework.jms.annotation.JmsListener;
import org.springframework.messaging.handler.annotation.SendTo;
import org.springframework.stereotype.Component;

import javax.naming.InsufficientResourcesException;

@Component
public class QueueListener {
    @JmsListener(destination = "publish.queue", containerFactory = "jmsListenerContainerQueue")
    @SendTo("out.queue")
    public String receive(String text){
        System.out.println("QueueListener: consumer-a 收到一条信息: " + text);
                return "consumer-a received : " + text;
    }
}

package com.cxy.listener;

import org.springframework.jms.annotation.JmsListener;
import org.springframework.stereotype.Component;

@Component
public class TopicListener {
    @JmsListener(destination = "publish.topic", containerFactory = "jmsListenerContainerTopic")
    public void receive(String text){
        System.out.println("TopicListener: consumer-a 收到一条信息: " + text);
    }
}

启动类:

package com.cxy;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

/**
 * Hello world!
 *
 */
@SpringBootApplication
public class App 
{
    public static void main( String[] args )
    {
         SpringApplication.run(App.class,args);
    }
}

执行结果:
