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;
@controller
public 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硕编程。
