Sping整合ActiveMQ(一.简单Queue通信)

简单配置:只作JMSTemplate和Destination的配置,进行简单的消息传送

 2.Spring配置文件ApplicationContext.xml

<?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-2.0.xsd">

    <!--创建JMS连接工厂-->
    <bean id="connectionFactory" >
        <property name="brokerURL" value="tcp://localhost:61616"/>
    </bean>

    <!--声明ActiveMQ消息目标,目标可以是一个队列Queue,也可以是一个主题Topic-->
    <bean id="destination" >
        <constructor-arg index="0" value="FirstQueue"/>
    </bean>

    <!--配置JMS模板-->
    <bean id="jmsTemplate" >
        <property name="connectionFactory" ref="connectionFactory"/>
        <property name="defaultDestination" ref="destination"/>  <!--此处可省-->
    </bean>

</beans>

 3.发送消息测试类Sender

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.jms.core.MessageCreator;

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

public class Sender {
    public static void main(String[] args) {
        /*1.加载配置文件*/
        ApplicationContext ctx = new ClassPathXmlApplicationContext(
                new String[] { "classpath:/applicationContext.xml" });
        /*2.获取JmsTemplate实例对象*/
        JmsTemplate template = (JmsTemplate) ctx.getBean("jmsTemplate");
        /*当配置文件中的JmsTemplate的Bean中没有配置Destination的property的时候,
          使用如下注释的方式*/
        //Destination destination = (Destination) ctx.getBean("destination");
        //template.send(destination, new MessageCreator() {......}
        template.send(new MessageCreator() {
            @Override
            public Message createMessage(Session session) throws JMSException {
                return session.createTextMessage("发送消息:Hello ActiveMQ Text Message!");
            }
        });
        System.out.println("成功发送了一条JMS消息");
    }
}

 4.接收消息测试类Receiver

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.jms.core.JmsTemplate;

import javax.jms.JMSException;
import javax.jms.TextMessage;

public class Receive {
    public static void main(String[] args) throws JMSException {
        /*1.加载配置文件*/
        ApplicationContext ctx = new ClassPathXmlApplicationContext(
                new String[] { "classpath:/applicationContext.xml" });
        /*2.获取JMSTemplate实例*/
        JmsTemplate jmsTemplate = (JmsTemplate) ctx.getBean("jmsTemplate");
        //Destination destination = (Destination) ctx.getBean("destination");
        /*开始接收消息*/
        while (true) {        
            /*当配置文件中的JmsTemplate的Bean中没有配置Destination的property的时候,
            使用如下注释的方式*/            
            //TextMessage txtmsg = (TextMessage) template.receive(destination);
            TextMessage message = (TextMessage) jmsTemplate.receive();
            if (null != message) {
                System.out.println("收到消息为:" + message.getText());
            }
            else
                break;
        }
    }
}
