样式加载不出来，浏览器控制台报错：Resource interpreted as Stylesheet but transferred with MIME type text/html

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。

		}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());
