1.执行删除昨天的文件夹

public class CacheFileClaearJob implements Job,Runnable {

   public void execute(JobExecutionContext context) throws JobExecutionException {
       try {
           ServletContext servletContext =(ServletContext)context.getScheduler().getContext().get("servletContext");
           String realPath = servletContext.getRealPath("/").replace("\\", "/");
           String oldTempateFile = realPath+"/template/"+StringUtil.dateFormat(DateUtils.getDate(-1), "yyyy-MM-dd");
           File file = new File(oldTempateFile);
           if(file.exists()){
               FileUtil.deleteDir(file);
           }
       } catch (SchedulerException e) {
           // TODO Auto-generated catch block
           e.printStackTrace();
       }
   }

   public void run() {
       System.out.println("i am here run!");
   }

}

2.配置web启动监听器

public class QuartzListener implements ServletContextListener {

   public void contextDestroyed(ServletContextEvent arg0) {
       // TODO Auto-generated method stub

   }

   public void contextInitialized(ServletContextEvent servletContextEvent) {
       try {
           Scheduler sched = new StdSchedulerFactory().getScheduler();
           sched.getContext().put("servletContext", servletContextEvent.getServletContext());
       } catch (SchedulerException e) {
           e.printStackTrace();
       }


   }

}

3.配置web. xml

<listener>
       <listener-class>cn.com.jx.core.listener.QuartzListener</listener-class>
   </listener><listener>
       <listener-class>cn.com.jx.core.listener.QuartzListener</listener-class>
   </listener>
