<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%><%String path = request.getContextPath();String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";%><html><script type="text/javascript">  window.onload = function(){      window.parent.parent.location.href="<%=path%>/user/toLogin.action";  }</script></html>

做jsp的时候，把这些访问路径取出来，可以方便在页面动态设置访问路径

<%String path = request.getContextPath();System.out.printf(path);//获取项目上下文路径     /PerFinSWString basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";System.out.printf(request.getScheme());// 访问协议  httpSystem.out.printf(request.getServerName());//访问的项目地址  localhost；//request.getSercerPort()获取访问端口                                                                                              System.out.printf(basePath);//项目访问全路径     http://localhost:8080/PerFinSW/%>
