CSRF漏洞修复

\\ 在Jsp文件头引入
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>

\\ 在登录的jsp中添加
<%
    //增加随机数，解决 CSRF 漏洞
    String uuid = UUID.randomUUID().toString().replaceAll("-", "");
    request.getSession().setAttribute("randTxt",uuid);
    //设置cookie只读
    String sessionid = request.getSession().getId();
    response.setHeader("SET-COOKIE", "JSESSIONID=" + sessionid + "; secure ; HttpOnly");
%>

\\ form表单中添加一个隐藏域：Input
<input type="hidden" name="randSesion"  value = "<%=request.getSession().getAttribute("randTxt")%>" />
