• springboot集成activeMq


    一,activeMq安装

    1,下载activeMq,放置到电脑某个目录,

    2,直接运行

    /bin/activemq.bat脚本,即可启动activeMq

    3,访问网址localhost:8161,即可查看activeMq网页界面

    4,activeMq目录中有一些例子,可以参考;

    二,springboot集成activeMQ

    1,添加依赖

    <!-- mq begin -->
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-activemq</artifactId>
            </dependency>
    
            <dependency>
                <groupId>org.apache.activemq</groupId>
                <artifactId>activemq-pool</artifactId>
                <!-- <version>5.7.0</version> -->
            </dependency>
    
            <!-- mq end -->

    2,添加activeMQ配置信息

    spring.activemq.broker-url=tcp://localhost:61616   #activeMQ地址信息,注意访问端口是61616
    #spring.activemq.broker-url=failover:(tcp://localhost:61616,tcp://localhost:61617)
    spring.activemq.close-timeout=5000
    spring.activemq.in-memory=false   
    #spring.activemq.pool.enabled=true
    spring.activemq.pool.max-connections=100
    spring.activemq.send-timeout=3000
    #activeMQ发送topic消息,需要此配置
    #spring.jms.pub-sub-domain=true     
    #信任所有的包
    spring.activemq.packages.trust-all=true
    #queque 及 topic配置信息
    queque.police=queque.police     
    queue.edu=queue.edu
    topic.pbc=topic.pbc
    topic.veh=topic.veh

    3,配置类

    package org.spring.web.component;
    
    import javax.jms.Queue;
    import javax.jms.Topic;
    
    import org.apache.activemq.ActiveMQConnectionFactory;
    import org.apache.activemq.command.ActiveMQQueue;
    import org.apache.activemq.command.ActiveMQTopic;
    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 org.springframework.jms.core.JmsMessagingTemplate;
    
    //MQ configuration class
    //主要配置 配置信息中的 spring.jms.pub-sub-domain 属性值信息,可以实现同时发送queue和topic信息
    @Configuration public class MqConfig { /* @Bean public ActiveMQConnectionFactory connectionFactory() { return new ActiveMQConnectionFactory("admin", "admin", "tcp://localhost:61616"); }*/ @Bean public JmsListenerContainerFactory<?> jmsListenerContainerTopic(ActiveMQConnectionFactory connectionFactory) { DefaultJmsListenerContainerFactory bean = new DefaultJmsListenerContainerFactory(); bean.setPubSubDomain(true); bean.setConnectionFactory(connectionFactory); System.out.println("注入的connectionFactory>>>>>"+connectionFactory.getUserName()); return bean; }
    @Bean
    public JmsListenerContainerFactory<?> jmsListenerContainerQueue(ActiveMQConnectionFactory connectionFactory) { DefaultJmsListenerContainerFactory bean = new DefaultJmsListenerContainerFactory(); bean.setConnectionFactory(connectionFactory); bean.setPubSubDomain(false); return bean; } /* @Bean public JmsMessagingTemplate jmsMessagingTemplate(ActiveMQConnectionFactory connectionFactory){ return new JmsMessagingTemplate(connectionFactory); }*/ }

    4,注入mqBeans

    package org.spring.web.mq;
    
    import javax.jms.Queue;
    import javax.jms.Topic;
    
    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.annotation.EnableJms;
    
    /**
     *
     * 项目名称:spring-web 类名称:MqBans 类描述: 创建人:john 创建时间:2018年7月30日 上午7:30:18 修改人:john
     * 修改时间:2018年7月30日 上午7:30:18 修改备注:
     * 
     * @version
     *
     */
    @Configuration
    @EnableJms
    public class MqBans {
        @Value("${queque.police}")
        private String policeQueue;
        @Value("${queue.edu}")
        private String eduQueue;
        @Value("${topic.pbc}")
        private String pbcTopic;
        @Value("${topic.veh}")
        private String vehTopic;
    
        @Bean
        public Queue policeQueue() {
            return new ActiveMQQueue(policeQueue);
        }
    
        @Bean
        public Queue eduQueue() {
            return new ActiveMQQueue(eduQueue);
        }
    
        @Bean
        public Topic pbcTopic() {
            return new ActiveMQTopic(pbcTopic);
        }
    
        @Bean
        public Topic vehTopic() {
            return new ActiveMQTopic(vehTopic);
        }
    
    }

    5,生产者

    package org.spring.web.mq;
    import javax.jms.Queue;
    import javax.jms.Topic;
    
    import org.spring.web.entity.User;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.boot.CommandLineRunner;
    import org.springframework.jms.core.JmsMessagingTemplate;
    import org.springframework.stereotype.Component;
    
    @Component
    public class Producer implements CommandLineRunner {
        
        @Autowired
        private JmsMessagingTemplate jmsMessagingTemplate;
    
        @Autowired
        private Queue policeQueue;
        
        @Autowired
        private Topic pbcTopic;
        
        @Autowired
        private Topic vehTopic;
        
        @Override
        public void run(String... args) throws Exception {
            for(int i=0;i<1;i++){    
                send("Sample message"+i);
            }
            sendTopic("topic send");
        }
    
        public void send(String msg) {
            this.jmsMessagingTemplate.convertAndSend(this.policeQueue, msg);
            System.out.println("Message was sent to the policeQueue");
    
        }
    
        public void sendTopic(String msg){
            System.out.println("消费者发送topic消息");
            this.jmsMessagingTemplate.convertAndSend(this.pbcTopic,msg);
            System.out.println("Message was sent to the pbcTopic");
        }
        
        
    }

    6,消费者

    package org.spring.web.mq;
    
    import javax.jms.JMSException;
    import javax.jms.Message;
    import javax.jms.ObjectMessage;
    
    import org.spring.web.entity.User;
    import org.springframework.jms.annotation.JmsListener;
    import org.springframework.messaging.handler.annotation.SendTo;
    import org.springframework.stereotype.Component;
    
    @Component
    public class Consumer {
    
        @JmsListener(destination = "${queque.police}",containerFactory="jmsListenerContainerQueue")
        @SendTo("out.queue")
        public String receiveQueue(String text) {
            System.out.println("police消费者1接受到的消息");
            System.out.println(text);
            return "sample.queue接受的消息>>>>>" + text;
        }
        
        @JmsListener(destination = "${queque.police}",containerFactory="jmsListenerContainerQueue")
        public void receiveQueue2(String text){
           System.out.println("police消费者2接受到的消息");
           System.out.println(text);
           
        }
         
        @JmsListener(destination = "out.queue",containerFactory="jmsListenerContainerQueue")
        public void receiveOutQueue(String text) {
            System.out.println("out.Queue接受到的信息" + text);
        }
        
        @JmsListener(destination = "${topic.pbc}",containerFactory="jmsListenerContainerTopic")
        public void receiveTopic(String text){
            System.out.println("pbc1消费者接受的信息");
            System.out.println(text);
        }
        @JmsListener(destination = "${topic.pbc}",containerFactory="jmsListenerContainerTopic")
        public void receiveTopic2(String text){
            System.out.println("pbc2消费者接受的信息"+text);
        }
        
        @JmsListener(destination = "${topic.veh}",containerFactory="jmsListenerContainerTopic")
        public void receiveTopicUser(Message m){
            System.out.println("接受到的对象信息message>>>>"+m);
            User  user=new User();
             if(m instanceof  ObjectMessage){
                 ObjectMessage objectMessage=(ObjectMessage) m;
                 System.out.println("objectMessage>>>>>>>"+objectMessage);
                 try {
                    user=(User) objectMessage.getObject();
                    
                } catch (JMSException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
             }
            
            System.out.println("消费者接受的用户对象信息"+user);
        }
        
    }

    总结:

     1,activeMq的端口号是61616;

     2,使用topic,需要配置 spring.jms.pub-sub-domain=true;

     3,queque如果没有消费者,会将信息存储到queue中;

     4,主方法启动的时候,消费者的监听已经生效;

     5,发送的消息为对象的时候,需要将对象序列化;消费者接受对象信息的时候需要使用ObjectMessage进行转化;

     6,使用JmsListener注解中的containerFactory属性,可以配置spring.jms.pub-sub属性,实现同事接收queque和topic;

     7,queque为点对点模式;tipic为发布订阅模式;
