【ActiveMQ入门-8】ActiveMQ学习-与Spring集成

概述：

消费者：同步接收；

目的地：topic

环境：

1. HelloSender.java；
2. JMSTest.java；
3. ProxyJMSConsumer.java；
4. applicationContext-jms.xml（配置文件）；

需要使用的jar包如下：

源文件：

package com.ll.springActiveMQ1;

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

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

public class HelloSender {

    /**
     * @param args
     * jmsTemplate和destination都是在spring配置文件中进行配制的
     * Sender只使用了配置文件中的jmsFactory，jmsTemplate，还有destination这三个属性
     */
    public static void main(String[] args) {
        ApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationContext-jms.xml");
        JmsTemplate template = (JmsTemplate) applicationContext.getBean("jmsTemplate");
        Destination destination = (Destination) applicationContext.getBean("destination");
        template.send(destination, new MessageCreator() {
            public Message createMessage(Session session) throws JMSException {
                return session.createTextMessage("发送消息：Hello ActiveMQ Text Message2！");
            }
        });
        System.out.println("成功发送了一条JMS消息");
    }
}

package com.ll.springActiveMQ1;

import javax.jms.Destination;
import javax.jms.TextMessage;

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

/**
 * JMS消费者 消息题的内容定义 消息对象 接收消息对象后： 接收到的消息体*
 * <p>
 */
public class ProxyJMSConsumer {

	/**
	 * 构造函数
	 */
	public ProxyJMSConsumer() {

	}

	/**
	 * 
	 */
	private JmsTemplate jmsTemplate;

	public JmsTemplate getJmsTemplate() {
		return jmsTemplate;
	}

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

	/**
	 * 监听到消息目的有消息后自动调用onMessage(Message message)方法
	 */
	public void recive() {
		ApplicationContext applicationContext = new ClassPathXmlApplicationContext(
				"applicationContext-jms.xml");
		Destination destination = (Destination) applicationContext
				.getBean("destination");
		while (true) {
			try {
				//同步接收
				TextMessage txtmsg = (TextMessage) jmsTemplate
						.receive(destination);
				if (null != txtmsg) {
					System.out.println("[DB Proxy] " + txtmsg);
					System.out.println("[DB Proxy] 收到消息内容为: "
							+ txtmsg.getText());
				} else {
					break;
				}
			} catch (Exception e) {
				e.printStackTrace();
			}

		}
	}
