ActiveMQ学习和研究

在ActiveMQ的资源让容器Tomcat管理时候，可以在Tomcat的配置文件中添加相关的配置信息。

说明：Tomcat示例版本6.0.14，其它版本在配置上可能有一些差异

1、准备jar包：

将ActiveMQ lib目录下的5个jar包复制到Tomcat lib目录下：

activemq-core-5.1.0.jar

activemq-web-5.1.0.jar

geronimo-j2ee-management_1.0_spec-1.0.jar

geronimo-jms_1.1_spec-1.1.1.jar

geronimo-jta_1.0.1B_spec-1.0.1.jar

修改配置文件：

修改Tomcat的conf/context.xml文件：

在<context></context>节点中添加以下内容：

	<Resource name="jms/ConnectionFactory"  
				auth="Container"  
				type="org.apache.activemq.ActiveMQConnectionFactory"
				description="JMS Connection Factory"
				factory="org.apache.activemq.jndi.JNDIReferenceFactory"
				brokerURL="tcp://localhost:61616"
				brokerName="LocalActiveMQBroker" />
				
	<Resource name="jms/Queue"  
				auth="Container"  
				type="org.apache.activemq.command.ActiveMQQueue"
				description="My Queue"
				factory="org.apache.activemq.jndi.JNDIReferenceFactory"
				physicalName="TomcatQueue" />

创建一个Java Web项目：

备注：必须是web项目，目前ActiveMQ依赖Tomcat，Tomcat是web容器，必须创建一个web容器。

消息接收者：

package easyway.activemq.app.demo2;

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

import org.springframework.jms.core.JmsTemplate;
/**
 * 消息接收者
 * @author longgangbai
 *
 */
public class MessageReceiver implements  MessageListener {
	private JmsTemplate jmsTemplate;
	  
	public JmsTemplate getJmsTemplate() {
		return jmsTemplate;
	}

	public void setJmsTemplate(JmsTemplate jmsTemplate) {
		this.jmsTemplate = jmsTemplate;
	}
    public void receive() throws JMSException{
    	 TextMessage text=(TextMessage)this.jmsTemplate.receive();
		System.out.println("receive="+text.getText());
    }
	public void onMessage(Message message) {
		 if(message instanceof TextMessage){
			 TextMessage text=(TextMessage)message;
			 try {
				System.out.println(text.getText());
			} catch (Exception e) {
			}
		 }
	}
    
}

消息发送者：

package easyway.activemq.app.demo2;

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

import org.springframework.jms.core.JmsTemplate;
import org.springframework.jms.core.MessageCreator;

/**
 * tomcat和activemq整合
 * 消息发送者
 * @author longgangbai
 *
 */
public class MessageSender {
  private JmsTemplate jmsTemplate;
  
  
  public void send(final String text){
	  jmsTemplate.send(new MessageCreator(){

		public Message createMessage(Session session) throws JMSException {
			// TODO Auto-generated method stub
			return session.createTextMessage(text);
		}
	  });
  }


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

业务类：

package easyway.activemq.app.demo2;

import javax.jms.JMSException;

import org.apache.xbean.spring.context.ClassPathXmlApplicationContext;
/**
 * 测试类
 * @author longgangbai
 *
 */
public class MessageTest {
	public void test() throws JMSException {
		ClassPathXmlApplicationContext ctx=new ClassPathXmlApplicationContext("app-activemq-tomcat.xml");
		MessageSender sender=(MessageSender)ctx.getBean("sender");
		MessageReceiver receive=(MessageReceiver)ctx.getBean("receiver");
		sender.send("helloworld");
		receive.receive();
	}

}

请问按照上面配置后，mq何时启动？上面代码或配置怎么可以看出来啊，3q

项目启动时候创建mq已经启动。

Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial

你创建context时候没有传递相关的参数，如果传递参数同时必须添加相关的包。java.naming.factory.initial所在的jar文件。
