写登录的时候出现的问题，样式时好时坏，浏览器控制台看到的信息是：

Uncaught SyntaxError: Unexpected token <

Resource interpreted as Stylesheet but transferred with MIME type text/html。

但是css的加载路径没有错，网上找了很多，看到http://bsr1983.iteye.com/blog/2246994，查看自己的登录拦截过滤器结合debug，果然是拦截器写的有问题，稍作改动下即可，不是action请求全部放过。

package cn.com.filter;import java.io.IOException;import javax.servlet.FilterChain;import javax.servlet.ServletException;import javax.servlet.ServletRequest;import javax.servlet.ServletResponse;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import javax.servlet.http.HttpSession;import org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter;import cn.com.jnpc.entity.User;/** * 登录拦截 * @author Uself 2017-10-17 下午1:10:00 * */public class LoginFilter extends StrutsPrepareAndExecuteFilter{@Overridepublic void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws  IOException,ServletException{HttpServletRequest rqs = (HttpServletRequest)request;HttpServletResponse rsp = (HttpServletResponse)response;String requestUrl = rqs.getRequestURI();String servletRequestUrl = rqs.getServletPath();/* * 非登录请求时，判断是否登录过（是否有session） * 有：继续 * 没有：重定向到登录请求 */if((!requestUrl.contains(".action") && !requestUrl.contains(".jsp")) || "/singleAparment/loginAction.action".equals(requestUrl)){super.doFilter(request, response, chain);}else{HttpSession session = rqs.getSession();User user = (User) session.getAttribute("USER_INFO");if(user == null || (user.getUserName() == null || user.getUserName().isEmpty())){rsp.sendRedirect(rqs.getContextPath());}else{super.doFilter(request, response, chain);}}}}
