定时器任务 TimerTask

1. 继承 TimerTask 类

public class GhDoctorStoppedTimeTask extends TimerTask 

2.在run(){} 方法里执行

public void run() {

int num = 0;
int numstop = 0;
try {
// 扫描省中医停诊
numstop = GhCheckScheduleSZYGuangGu();


} catch (Exception e1) {
e1.printStackTrace();
}
if (0 == num) {
System.out.println("无需更新");
} else {
System.out.println("更新成功");
}
if (0 == numstop) {
System.out.println("无需更新停诊");
} else {
System.out.println("停诊更新成功");
}
}

3.  在类 中调用方法

public class GhDoctorStoppedTimeTaskMain {
    
   private Timer timer = null;         
   public void contextInitialized(ServletContextEvent event){     
    timer = new Timer();  
    timer.schedule(new GhDoctorStoppedTimeTask(),0,1*10000);  //一分钟
//   timer.schedule(new GhDoctorStoppedTimeTask(),0,50*10000);  

  }  
       
    
   
   public void simpleJobTest() {
    timer = new Timer();  
    timer.schedule(new GhDoctorStoppedTimeTask(),0,60*10000);   
   }
   //销毁监听器，停止执行任务     
   public void contextDestroyed(ServletContextEvent event){           
          timer.cancel();     
    }     
}
