[activemq]+spring的使用

一、生产端(Producer)

applicationContext.xml中的配置：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="
   http://www.springframework.org/schema/beans
   http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">

    <!-- 真正可以产生Connection的ConnectionFactory，由对应的 JMS服务厂商提供 -->
    <bean id="targetConnectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory">
        <property name="brokerURL" value="tcp://192.168.137.1:61616" />
        <property name="userName" value="afeng" />
        <property name="password" value="111111" />
    </bean>

    <!-- Spring用于管理真正的ConnectionFactory的ConnectionFactory -->
    <bean id="connectionFactory"
          class="org.springframework.jms.connection.SingleConnectionFactory">
        <!-- 目标ConnectionFactory对应真实的可以产生JMS Connection的ConnectionFactory -->
        <property name="targetConnectionFactory" ref="targetConnectionFactory" />
    </bean>

    <!-- 定义JmsTemplate的Queue类型 -->
    <bean id="jmsTemplate" class="org.springframework.jms.core.JmsTemplate">
        <constructor-arg ref="connectionFactory"/>
        <!-- 非pub/sub模型（发布/订阅），即队列模式 -->
        <property name="pubSubDomain" value="false"/>
    </bean>

    <bean id="queueSender" class="com.afeng.utils.activeMq.QueueSender">
        <property name="JmsTemplate" ref="jmsTemplate"/>
    </bean>

    <!-- 定义JmsTemplate的Topic类型 -->
    <bean id="jmsTopicTemplate" class="org.springframework.jms.core.JmsTemplate">
        <!-- 这个connectionFactory对应的是我们定义的Spring提供的那个ConnectionFactory对象 -->
        <constructor-arg ref="connectionFactory"/>
        <!-- pub/sub模型（发布/订阅） -->
        <property name="pubSubDomain" value="true"/>
    </bean>

    <bean id="topicSender" class="com.afeng.utils.activeMq.TopicSender">
        <property name="jmsTemplate" ref="jmsTopicTemplate"/>
    </bean>

</beans>

两个封装的类：QueueSender

package com.afeng.utils.activeMq;

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;

@Component
public class QueueSender {

    private JmsTemplate jmsTemplate;//通过@Qualifier修饰符来注入对应的bean

    public JmsTemplate getJmsTemplate() {
        return jmsTemplate;
    }

    public void setJmsTemplate(JmsTemplate jmsTemplate) {
        this.jmsTemplate = jmsTemplate;
    }

    /**
     * 发送一条消息到指定的队列（目标）
     * @param queueName 队列名称
     * @param message 消息内容
     */
    public void send(String queueName,final String message){
        jmsTemplate.send(queueName, new MessageCreator() {
            public Message createMessage(Session session) throws JMSException {
                return session.createTextMessage(message);
            }
        });
    }
}

TopicSender

package com.afeng.utils.activeMq;

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;

@Component
public class TopicSender {
    private JmsTemplate jmsTemplate;

    public JmsTemplate getJmsTemplate() {
        return jmsTemplate;
    }

    public void setJmsTemplate(JmsTemplate jmsTemplate) {
        this.jmsTemplate = jmsTemplate;
    }

    public void send(String queueName, final String message) {
        this.jmsTemplate.send(queueName, new MessageCreator() {
            @Override
            public Message createMessage(Session session) throws JMSException {
                return session.createTextMessage(message);
            }
        });
    }
}

在实际场景中的使用：

@Autowired
    private QueueSender queueSender;

queueSender.send("spring-queue","要发送的数据");

二、消费端（Comsumer）

applicationContext.xml中的配置：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="
   http://www.springframework.org/schema/beans
   http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">

    <!-- 真正可以产生Connection的ConnectionFactory，由对应的 JMS服务厂商提供 -->
    <bean id="targetConnectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory">
        <property name="brokerURL" value="tcp://192.168.137.1:61616" />
        <property name="userName" value="afeng" />
        <property name="password" value="111111" />
    </bean>

    <!-- Spring用于管理真正的ConnectionFactory的ConnectionFactory -->
    <bean id="connectionFactory"
          class="org.springframework.jms.connection.SingleConnectionFactory">
        <!-- 目标ConnectionFactory对应真实的可以产生JMS Connection的ConnectionFactory -->
        <property name="targetConnectionFactory" ref="targetConnectionFactory" />
    </bean>

    <!--这个是队列目的地，点对点的 -->
    <bean id="queueDestination" class="org.apache.activemq.command.ActiveMQQueue">
        <constructor-arg>
            <value>spring-queue</value>
        </constructor-arg>
    </bean>
    <!--这个是主题目的地，一对多的 -->
    <bean id="topicDestination" class="org.apache.activemq.command.ActiveMQTopic">
        <constructor-arg value="spring-topic" />
    </bean>

    <!--监听 数据发生变化-->
    <bean id="itemChangeListener" class="com.afeng.listener.ItemChangeListener" />
    <bean class="org.springframework.jms.listener.DefaultMessageListenerContainer">
        <property name="connectionFactory" ref="connectionFactory" />
        <property name="destination" ref="queueDestination" />
        <property name="messageListener" ref="itemChangeListener" />
    </bean>

</beans>

监听的类ItemChangeListener：

package com.afeng.listener;

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

public class ItemChangeListener implements MessageListener {
    @Override
    public void onMessage(Message message) {
        try {
            TextMessage textMessage = null;
            String queuetxt = "";
            //取商品id
            if (message instanceof TextMessage) {
                textMessage = (TextMessage) message;
                queuetxt = textMessage.getText();
                }
            System.err.println("queuetxt="+queuetxt);
            } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
