今日总结

JSP生命周期测试代码：

<%@ page language="java" contentType="text/html; charset=utf-8"
pageEncoding="utf-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>jsp生命周期</title>
</head>
<body>
<%!
//声明变量
private int initCnt = 0;
private int serviceCnt = 0;
private int destroyCnt = 0;
%>
<%!
//初始化方法
public void jspInit(){
initCnt++;
System.out.println("jspInit(): JSP被初始化了"+initCnt+"次");
}
//销毁方法
public void jspDestroy(){
destroyCnt++;
System.out.println("JSP被销毁了"+destroyCnt+"次");
}
%>
<%
serviceCnt++;
System.out.println("Jsp响应了"+serviceCnt+"次");
String initString="初始化次数 : "+initCnt;
String serviceString="响应客户请求次数 : "+serviceCnt;
String destroyString ="销毁次数 : "+destroyCnt;
%>
<h1>结果如下：</h1>
<p><%= initString%></p>
<p><%= serviceString%></p>
<p><%= destroyString%></p>
</body>
</body>
</html>
