登陆中发现css页面不见了，变成了光秃秃的输入框问题

 变成了这种光秃秃的状态；

这种状态一般是css文件被过滤器拦截了，

当时的过滤器代码

import java.io.IOException;

import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;

import net.wanho.web.EncodingRequest;

public class EncodingFilter implements Filter {

    private FilterConfig filterConfig = null;

    public void init(FilterConfig fConfig) throws ServletException {
        this.filterConfig = fConfig;
    }

    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
            throws IOException, ServletException {

        String encoding = filterConfig.getInitParameter("charset");
        // 处理post请求编码问题
        request.setCharacterEncoding(encoding);
//            response.setCharacterEncoding(encoding);
        response.setContentType("text/html;charset=" + encoding);
        chain.doFilter(request, response);
    }

    public void destroy() {

    }

}

这种情况就是一下子把css页面也过滤掉了，所以我们要再增加一个过滤页面；

import javax.servlet.*;
import javax.servlet.annotation.WebFilter;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
@WebFilter("*.css")
public class CSSFilter implements Filter {
    @Override
    public void init(FilterConfig filterConfig) throws ServletException {

    }

    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {


//            response.setCharacterEncoding(encoding);
        response.setContentType("text/css;charset=utf-8");//注意这里text/css
        chain.doFilter(request, response);

    }

    @Override
    public void destroy() {

    }
}

然后重启一下编辑器，清除浏览器缓存，再试一次
