servlet过滤器会抑制许多swagger响应（包括图像和css），以便在浏览器上创建swagger ul gui屏幕。请通过以下代码段绕过此类行为。

@Component
public class DomainAuthorizationFilter implements Filter {

    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
            throws IOException, ServletException {
        HttpServletRequest httpRequest = (HttpServletRequest) request;
        HttpServletResponse httpResponse = (HttpServletResponse) response;
        if(httpRequest.getRequestURI().trim().toLowerCase().matches(".*swagger-.*|.*api-docs.*"))
        {           request.getRequestDispatcher(httpRequest.getServletPath()).forward(request, response);
            return;
        }
        else {
              // Your login in the filter.
        }
        chain.doFilter(request, response);
    } 
}
