消息中间件与JMS和spring框架的整合使用

整合其实与原生的非常相似,只是将重复的很多步骤都写在了配置文件中,将所有能new的都交给了spring进行管理

生产者productor项目

第一步:导包

导入一个是跟spring框架整合的包, 一个是消息中间件的包,这时候因为有跟spring整合的包,所以spring的所有包都要导入,我们对pring的版本进行了统一都是使用4.2.4版本

pom.xml 文件

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        </dependency>
    </dependencies>

</project>

第二步:生产者的spirngxml文件

解释:将原生的工厂交给spring与jms结合的工厂,然后创建一个template ,通过template就可以进行所有操作,再造一个目的地就可以了

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">

    <context:component-scan base-package="cn.itcast.productor"/>

    <!--创建工厂实例化对象-->
    <bean id="activeMQConnectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory">
        <property name="brokerURL" value="tcp://192.168.5.111:61616"/>
    </bean>
    <!--真正的工厂:spring-jms工厂-->
    <bean id="connectionFactory" class="org.springframework.jms.connection.SingleConnectionFactory">
        <property name="targetConnectionFactory" ref="activeMQConnectionFactory"></property>
    </bean>

    <!--获取模板-->
    <bean id="jmsTemplate" class="org.springframework.jms.core.JmsTemplate">
        <property name="connectionFactory" ref="connectionFactory"/>
    </bean>

    <!--创建队列的目的地,点对点-->
    <bean class="org.apache.activemq.command.ActiveMQQueue">
        <constructor-arg value="springjms-productor-queue-demo"/>
    </bean>

    <!--创建广播的目的地distination,点对面-->
    <bean class="org.apache.activemq.command.ActiveMQTopic">
        <constructor-arg value="springjms-productor-topic-demo"/>
    </bean>

</beans>

第三步: 发送中间件消息方法

package cn.itcast.productor;

import org.apache.activemq.command.ActiveMQQueue;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.jms.core.MessageCreator;
import org.springframework.stereotype.Component;

import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.Session;
import javax.jms.TextMessage;

@Component
public class QueueProductor {
    //注入模板
    @Autowired
    private JmsTemplate jmsTemplate;
    //注入目的地
    @Autowired
    private ActiveMQQueue activeMQQueue;
    
    //发送消息
    public void sendTextMessage(final String text){
        jmsTemplate.send(activeMQQueue, new MessageCreator() {
            public Message createMessage(Session session) throws JMSException {
                return session.createTextMessage(text);
            }
        });
    }
}

第四步:测试发送

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath:applicationContext-jms-producer.xml")

public class quequeAndTopicTest {
    @Autowired
    private QueueProductor queueProductor;
    @Autowired
    private TopicProductor topicProductor;

    //queuqe类型生产者测试
    @Test
    public void queueProductorTest() throws IOException {
        queueProductor.sendTextMessage("我是生产者:springjms_productor下面的queue生产者.");
    }

消费者consumer项目

第一步:导包,与生产者一样,srpring包,中间件包,结合包

第二步:书写配置文件,与生产者非常相似

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
    <!--扫描包,将自身交给spring容器进行管理-->
    <!--<context:component-scan base-package="cn.itcast.demo"/>-->

    <!--实例化工厂类-->
    <bean id="connectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory">
        <property name="brokerURL" value="tcp://192.168.5.111:61616"/>
    </bean>
    <!--真正的工厂类,spring-jms结合起来的,将上面的工厂类作为一个属性-->
    <bean id="SingleconnectionFactory" class="org.springframework.jms.connection.SingleConnectionFactory">
        <property name="targetConnectionFactory" ref="connectionFactory"/>
     </bean>

    <!--实例化队列,目的地-->
    <bean id="destination" class="org.apache.activemq.command.ActiveMQQueue">
        <constructor-arg value="springjms-productor-queue-demo"/>
    </bean>
    <!--监听类:监听包下的quequeConsumer-->
    <bean id="myMessageListern" class="cn.itcast.demo.QueueConsumer"></bean>
    <!--消息监听容器-->
    <bean class="org.springframework.jms.listener.DefaultMessageListenerContainer">
        <property name="connectionFactory" ref="SingleconnectionFactory"/>
        <property name="destination" ref="destination"/>
        <property name="messageListener" ref="myMessageListern"/>
    </bean>
    


    <!--下面是topic相关的========================================-->

    <!--这个是主题目的地，发布订阅的  文本信息-->
    <bean id="topicdestination" class="org.apache.activemq.command.ActiveMQTopic">
        <constructor-arg value="springjms-productor-topic-demo"/>
    </bean>
    <!-- 我的监听类 -->
    <bean id="topicConsumer" class="cn.itcast.demo.TopicConsumer"></bean>
    <!-- 消息监听容器 -->
    <bean class="org.springframework.jms.listener.DefaultMessageListenerContainer">
        <!--连接工厂-->
        <property name="connectionFactory" ref="SingleconnectionFactory"/>
        <!--消息消费的目的地-->
        <property name="destination" ref="topicdestination"/>
        <!--消息的监听类-->
        <property name="messageListener" ref="topicConsumer"/>
    </bean>
</beans>

第三步: 接收消息

package cn.itcast.demo;
import org.springframework.stereotype.Component;

import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.MessageListener;
import javax.jms.TextMessage;

@Component
public class QueueConsumer implements MessageListener {
    public void onMessage(Message message) {
        //获取消息
        TextMessage textMessage= (TextMessage) message;
        try {
            System.out.println("消费者接收到的消失是:"+textMessage.getText());
        } catch (JMSException e) {
            e.printStackTrace();
        }
    }
}

第四步: 测试:想办法让消费者一直活着接收消息

System.in.read();  一直等待键盘录入读取,保证消费者一直生存

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath:applicationContext_jms_consumer-queue.xml")

public class test {
  
    @Test
    public  void  queueConsumerTest(){
        try {
            System.in.read();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
