Exception information:

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

Possible causes

The filter or some place turns all resource requests to text/HTML

Inspection method

Using browser to view request header and response header

Mainly check the content type of request header and response header

The style sheet should be text/CSS, and the request sent to the server and the server’s response to the client should be text/CSS

The problem I personally encountered in the project is that when using the filter to code all requests, the CSS file is also processed

The filter code before modification is

　　　　　　System.out.println("**********AllFilter start work*********");
        HttpServletRequest request=(HttpServletRequest)req;
        HttpServletResponse response=(HttpServletResponse)res;
       response.setCharacterEncoding("text/html; charset=UTF-8");

Treatment method

The request should be classified. When it is a kind of file such as CSS, it is requested in the original way and not processed. Other requests are processed again. The modified code is as follows:

System.out.println("**********AllFilter start work*********");
        HttpServletRequest request=(HttpServletRequest)req;
        HttpServletResponse response=(HttpServletResponse)res;

        String url=request.getRequestURI();
        System.out.println("url:" +url);
        if(url.indexOf(".css")>0||url.indexOf(".js")>0||url.indexOf(".png")>0) {
            chain.doFilter(request, response);
            return;
        }
        response.setContentType("text/html;text/html; charset=UTF-8");
