springMVC+activemq整合注解方式

傷城~ 2022-07-13 08:45 197阅读 0赞

前言：用了一次mq，由于xml配置+注解的方式出现类加载问题并且对spring类加载机制不是很熟悉，索性就改成注解方式来解决问题。

配置过程中，搜索了好久，各种配置失败，这里给出总结经验，勉励一下自己吧。

**1.xml监听配置方式及测试程序，请参阅**

http://www.cnblogs.com/leiOOlei/p/5075402.html

**2.activemq注解监听配置如下**

（1）请自行配置springmvc+maven环境（参看前几篇博客），下载activemq

（2）maven引入的包，在pom.xml文件引入。

注意：activemq-all用的5.8.0，同时测试了5.12.1和5.14.3版本，无法识别<jms:annotation-driven/>配置，不能实现注解。

这里困扰好久，望有成功者可以指点一二，感激不尽。

                <artifactId>xbean-spring</artifactId>

            </dependency>
    	<dependency>

                <version>5.8.0</version>
            </dependency>

（3）activemq.xml文件配置

<?xml version="1.0" encoding="UTF-8"?>
    
    <beans xmlns="http://www.springframework.org/schema/beans" 
    	xmlns:context="http://www.springframework.org/schema/context" 
    	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    	xmlns:amq="http://activemq.apache.org/schema/core"
        xmlns:jms="http://www.springframework.org/schema/jms"
        xsi:schemaLocation="http://www.springframework.org/schema/beans   
            http://www.springframework.org/schema/beans/spring-beans-4.1.xsd
            http://www.springframework.org/schema/context   
            http://www.springframework.org/schema/context/spring-context-4.1.xsd
            http://www.springframework.org/schema/jms
            http://www.springframework.org/schema/jms/spring-jms-4.1.xsd
            http://activemq.apache.org/schema/core
            http://activemq.apache.org/schema/core/activemq-core-5.8.0.xsd">
     	<amq:connectionFactory id="jmsConnectionFactory" brokerURL="tcp://localhost:61616" userName="admin" password="admin" />
    
        <bean id="jmsConnectionFactoryExtend" class="org.springframework.jms.connection.CachingConnectionFactory">
            <constructor-arg ref="jmsConnectionFactory" />
            <property name="sessionCacheSize" value="100" />
        </bean>
    
        
        <bean id="jmsMessageConverter" class="org.springframework.jms.support.converter.SimpleMessageConverter" />
    
        
        
        <bean id="jmsQueueTemplate" class="org.springframework.jms.core.JmsTemplate">
            <constructor-arg ref="jmsConnectionFactoryExtend" />
            
            <property name="pubSubDomain" value="false" />
            <property name="messageConverter" ref="jmsMessageConverter"></property>
        </bean>
    
        
        <bean id="jmsTopicTemplate" class="org.springframework.jms.core.JmsTemplate">
            <constructor-arg ref="jmsConnectionFactoryExtend" />
            
            <property name="pubSubDomain" value="true" />
            <property name="messageConverter" ref="jmsMessageConverter"></property>
        </bean>
        <bean id="jmsListenerContainerFactory" class="org.springframework.jms.config.DefaultJmsListenerContainerFactory">
            <property name="connectionFactory" ref="jmsConnectionFactoryExtend"/>
        </bean>
        
        <jms:annotation-driven />
    </beans>

（4）监听消息测试代码， 注意：类上面的两个注解，丢了无法启动监听

package com.cms.mmc.activemq;
    
    import java.util.List;
    import java.util.Map;
    
    import javax.annotation.Resource;
    import javax.jms.JMSException;
    import javax.jms.Message;
    import javax.jms.TextMessage;
    
    import org.springframework.jms.annotation.EnableJms;
    import org.springframework.jms.annotation.JmsListener;
    import org.springframework.stereotype.Component;
    
    import com.cms.mmc.activemq.service.IServiceProducer;
    
    //spring配置监听队列中的消息
    @Component
    @EnableJms
    public class QueueMsgListener{
    
        //当收到消息后，自动调用该方法,spring配置默认监听器，负责接收消息
        @JmsListener(containerFactory="jmsListenerContainerFactory",destination = "mssactivemq")
        public void onMessage(Message message) {
            TextMessage tm = (TextMessage) message;
            try {
            	System.out.println(tm.getText());
            } catch (JMSException e) {
                e.printStackTrace();
            }
        }
    }

（5）测试监听启动,启动tomcat，启动activemq，:\\apache-activemq-5.14.3\\bin\\win64，双击activemq.bat，启动后

浏览器输入http://localhost:8161/admin，未修改密码情况，用户名密码admin admin。看到如下图片，number of consumers =1，

当向mssactivemq队列发送消息时，会在控制台打印该消息，发送消息程序请看（6），输出如下

\{"code":"equipment","commKey":"send","pId":"00ec55041f7c4534a4b6740b9187cf5d","id":"222","items":"json对象","key":"222\_00ec55041f7c4534a4b6740b9187cf5d"\}

（6）发送消息测试代码如下

package com.cms.mmc.activemq;
    
    import javax.jms.Connection;
    import javax.jms.ConnectionFactory;
    import javax.jms.Destination;
    import javax.jms.JMSException;
    import javax.jms.MessageProducer;
    import javax.jms.Session;
    import javax.jms.TextMessage;
    
    import org.apache.activemq.ActiveMQConnectionFactory;
    import org.springframework.jms.core.JmsTemplate;
    
    import com.alibaba.fastjson.JSONObject;
    
    //向mq发送2条数据
    public class M2Producer {
    
    	public M2Producer(){
    		
    	}
       
    	public static void main(String[] args) {
    		ConnectionFactory connectionFactory = new ActiveMQConnectionFactory("tcp://localhost:61616");
    		try {
    			Connection connection = connectionFactory.createConnection();
    			connection.start();
    
    			Session session = connection.createSession(Boolean.TRUE,Session.AUTO_ACKNOWLEDGE);
    			Destination destination = session.createQueue("mssactivemq");
    
    			MessageProducer producer = session.createProducer(destination);
    			JSONObject jsonObject = new JSONObject();
    			jsonObject.put("commKey", "send");
    			jsonObject.put("id", "222");
    			jsonObject.put("pId", "00ec55041f7c4534a4b6740b9187cf5d");
    			jsonObject.put("key", "222_00ec55041f7c4534a4b6740b9187cf5d");
    			jsonObject.put("items", "json对象");
    			jsonObject.put("code", "equipment");
    			for (int i = 0; i < 1; i++) {
    				System.out.println("send...messageAA --->" + jsonObject);
    				TextMessage message = session.createTextMessage(jsonObject.toJSONString());
    				// 通过生产者发出消息
    				producer.send(message);
    			}
    			
    			session.commit();
    			session.close();
    			connection.close();
    		} catch (JMSException e) {
    			e.printStackTrace();
    		}
    	}
    }
