ActiveMQ和Tomcat的整合应用
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();
}
}
