过滤器过滤response，设置成response.setContentType(“text/html；charset=utf-8“)；导致CSS无法正常加载

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

方法一：

方法二：

@WebFilter("/")
public class EncodingFilter implements Filter{
    
    

	@Override
	public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
			throws IOException, ServletException {
    
    
		request.setCharacterEncoding("utf-8");
		String contentType = ((HttpServletRequest)request).getHeader("Accept");
		response.setContentType(contentType == null ? "text/html;charset=utf-8" : contentType + ";charset=utf-8");
		chain.doFilter(request, response);
	}
	
}

方法三：
获取url类型，只要是css或者js等其他资源就修改contentType

方法四：
使用ServletResponse的子类HttpServletResponse来设置过滤。完美解决！
