JSP权限控制源码

        偶然翻到很多年前，刚学Java的时候学的一段代码。或许，现在让写，还写不出来了。技术如潮、不进则退。还是年轻好啊，思路清晰、精神充沛。

[java] 
<%@ page contentType="text/html; charset=gb2312" %> 
 
<%@ page import="qlsoft.PWebs.Business.PermitBean" %> 
<jsp:useBean id="permitBean" scope="session" class="qlsoft.PWebs.Business.PermitBean" /> 
<%@ page import="qlsoft.PWebs.Business.MemberBean" %> 
<jsp:useBean id="memberBean" scope="session" class="qlsoft.PWebs.Business.MemberBean" /> 
<% 
    String action= request.getParameter("action"); 
%> 
        <script language="javascript"> 
            //alert("Permit request action:" + "<%=action%>"); 
        </script> 
    <% 
    if("login".equalsIgnoreCase(action)) 
    {//会员登录:验证用户身份,并设置Session变量及已登录标志 
        //获取登录参数 
        String userName= request.getParameter("username"); 
        String userPwd= request.getParameter("password"); 
        System.out.println("帐号:" + userName + "密码:" + userPwd); 
        if(userName == null || userName == "" || userPwd == null || userPwd == "") 
        {//请求的参数无效 
    %> 
        <script language="javascript"> 
            alert("没有会员登录必须的请求参数！"); 
            window.history.go(-1); 
        </script> 
    <% 
        } 
        else 
        {//参数有效 
            if(permitBean.memberLogin(userName,userPwd)) 
            {//登录成功
