1、jsp
<%@ page language="java" contentType="text/html;
charset=UTF-8" pageEncoding="UTF-8"%><%@taglib uri="http://www.springframework.org/tags/form" prefix="form"%><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head><meta http-equiv="Content-Type" content="text/html;
charset=ISO-8859-1"><title>Insert title here</title><script type="text/javascript">function st(){
window.location.href="startCamera.html" rel="external nofollow" ;
}
function en(){
window.location.href="cancelCamera.html" rel="external nofollow" ;
}
</script></head><body><input type="button" value="开始" onclick="st()"/><input type="button" value="结束" onclick="en()"/></body></html>
2、Controller
package net.spring.controller;
import java.util.Timer;
import net.spring.utils.CameraTask;
import net.spring.utils.HKTest;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controllerpublic class HKController {
public Timer timer = null;
public CameraTask mCameraTask = null;
public static boolean status = false;
@RequestMapping("startCamera") public String startCamera() {
if (!status) {
// HKTest.getInstance().login();
if (timer == null) {
timer = new Timer();
}
if (mCameraTask == null) {
mCameraTask = new CameraTask();
}
timer.schedule(mCameraTask, 0, 1000);
status = true;
}
return "camera";
}
@RequestMapping("cancelCamera") public String cancelCamera() {
if (status) {
if (timer != null) {
timer.cancel();
timer = null;
}
if (mCameraTask != null) {
mCameraTask.cancel();
mCameraTask = null;
}
// HKTest.getInstance().logout();
status = false;
}
return "camera";
}
}
3、TimerTask
package net.spring.utils;
import java.util.TimerTask;
public class CameraTask extends TimerTask {
@Override public void run() {
//dosomthing;
}
}
以上这篇jsp有两个按钮来控制Timer的开始和结束方法就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持脚本之家。
