nutz 有没有文件读取配置

nutz 有没有文件读取配置
springboot 配置拦截请求 /profile/** 直接读取文件
这个 nutz 有类似的支持吗

package com.ruoyi.framework.config;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.ViewControllerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

/**

 * @author ruoyi
 */
@Configuration
public class ResourcesConfig implements WebMvcConfigurer
{
    /**
     * 首页地址
     */
    @Value("${shiro.user.indexUrl}")
    private String indexUrl;

    /**
     * 默认首页的设置，当输入域名是可以自动跳转到默认指定的网页
     */
    @Override
    public void addViewControllers(ViewControllerRegistry registry)
    {
        registry.addViewController("/").setViewName("forward:" + indexUrl);
    }

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry)
    {
        /** 文件上传路径 */
        registry.addResourceHandler("/profile/**").addResourceLocations("file:" + RuoYiConfig.getProfile());

        /** swagger配置 */
        registry.addResourceHandler("swagger-ui.html").addResourceLocations("classpath:/META-INF/resources/");
        registry.addResourceHandler("/webjars/**").addResourceLocations("classpath:/META-INF/resources/webjars/");
    }
}

木有，写个入口方法(支持**)或者Filter呗

优先级调下，然后getPathSpec return "/*"; 试试

有没有进doFilter方法?

过滤器获取不到 URL

    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) {
        String url = Mvcs.getReq().getRequestURI();
        // path是指欲下载的文件的路径。
        String path =url.substring(url.indexOf("/profile"));
        File file = new File(path);
        // 取得文件名。
        String filename = file.getName();
        // 取得文件的后缀名。
        String ext = filename.substring(filename.lastIndexOf(".") + 1).toUpperCase();

        // 以流的形式下载文件。
        try (InputStream fis  = new BufferedInputStream(new FileInputStream(path))){
            byte[] buffer = new byte[fis.available()];
            fis.read(buffer);
            fis.close();
            // 清空response
            response.reset();
            // 设置response的Header
            Mvcs.getResp().addHeader("Content-Disposition", "attachment;filename=" + new String(filename.getBytes()));
            Mvcs.getResp().addHeader("Content-Length", "" + file.length());
            OutputStream toClient = new BufferedOutputStream(response.getOutputStream());
            response.setContentType("application/octet-stream");
            toClient.write(buffer);
            toClient.flush();
            toClient.close();
