jmx控制tomcat
以前所作的一切应用程序基本上都是由tomcat容器，控制web应用程序的生死、这两天简单的学习了下jmx，有所感悟。所以反其道而行之：自己写一个JmxAgent来控制tomcat的生、死，从而达到：利用jmx来控制资源的目的。
在项目中集成tomcat我很早以前就听说过，一直以为很神秘：技术含量很高。通过我自己的研究：发现其实就比helloworld难一点。上代码。
我的实现很简单：一个标准的mbean，挂上一个htmlAdaper和另外一个rmiconnector以备访问。
代码如下：MBean接口：
package com.cxz.jmx;public interface TcMgrMBean {public void startTc();public void stopTc();}package com.cxz.jmx;import org.apache.catalina.startup.Bootstrap;public class TcMgr implements TcMgrMBean, Runnable {public void startTc() {Thread thread = new Thread(this, "tomcat-6");thread.start();}public void stopTc() {//具体参阅tc6 srcString[] params = new String[1];params[0] = "stop";Bootstrap.main(params);}public void run() {//具体参阅tc6 srcString[] args = new String[0];Bootstrap.main(args);}}package com.cxz.jmx;import javax.management.MBeanServer;import javax.management.MBeanServerFactory;import javax.management.ObjectName;import javax.management.remote.JMXConnectorServer;import javax.management.remote.JMXConnectorServerFactory;import javax.management.remote.JMXServiceURL;import com.sun.jdmk.comm.HtmlAdaptorServer;public class TcAgent {private MBeanServer server = null;public TcAgent() {//The default constructor of the Agent}public void assemble() throws Exception {server = MBeanServerFactory.createMBeanServer("TcAgent");HtmlAdaptorServer adapter = new HtmlAdaptorServer();//regist the MBeanTcMgr manager = new TcMgr();server.registerMBean(manager, new ObjectName("TcAgent:name=TcManager"));//regist the HtmlAdaptoradapter.setPort(9092);server.registerMBean(adapter, new ObjectName("TcAgent:name=htmlAdaptor,port=9092"));adapter.start();//compose the RMIConnectorJMXServiceURL url = new JMXServiceURL("service:jmx:rmi:///jndi/rmi://10.237.81.67:9999/server");JMXConnectorServer cs = JMXConnectorServerFactory.newJMXConnectorServer(url, null, server);cs.start();}public static void main(String[] args) throws Exception {new TcAgent().assemble();}}
