tomcat用线程监控另一个服务

• 1 起一个监控服务，写一个listner，服务启动即开启监控线程

public class CheckServerListner implements ServletContextListener {

	private CheckServerThread myThread;
	
	@Override
	public void contextDestroyed(ServletContextEvent arg0) {
		if (myThread != null && myThread.isInterrupted()) {  
	           myThread.interrupt();  
	       } 
	}

	@Override
	public void contextInitialized(ServletContextEvent arg0) {
		String str = null;  
		if (str == null && myThread == null) {  
			myThread = new CheckServerThread();  
		    myThread.start(); // servlet 上下文初始化时启动 socket
		    System.out.println("监控IPTVservice服务线程启动");
		}  

	}

}

• 2 写一个监控线程，没五分钟监控一次

public class CheckServerThread extends Thread {

	@Override
	public void run() {
		while(true){
            try {
            	sleep(5*60*1000);
                //1、 调用被监控服务，
            	// 判断  正常响应则没事了
            	//2、异常则调用邮箱服务，告警
                //String result = Util.httpGet("http://192.168.1.118:8081/IPTVService/checkServer.do");
                String result = Util.httpGet("http://xxx.xxx.xxx.xxx:8082/IPTVService/checkServer.do");
                System.out.println(result);
                if(!"OK".equals(result)){
                	Util.httpGet("http://xx.xx.xx.xx:8888/web/iptv/guangdong/[email protected]&checkCode=sichuanggaojing");
                	
                }
                
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
	}
