action配置:
HTML代码:
<%@ page language="java" contentType="text/html; charset=utf-8" pageEncoding="utf-8"%> <% String path = request.getContextPath(); String basePath = request.getScheme() + "://" + request.getServerName() + ":" + request.getServerPort() + path; %> <%@taglib prefix="s" uri="/struts-tags"%>Login page /html/styles/styles.css" rel="external nofollow" />
