文件上传自定义上传路径

文件上传自定义上传路径，并且根据返回的Url可以进行访问

配置文件 .yml

#文件上传路径
file:
  #虚拟路径，对外展示
  staticAccessPath: /file/**
  #本地测试真实路径，可以改为服务器tomcat中路径
  fileupload:  F:/fileupload/

Controller层

@PostMapping("/upload")
public R upload(@RequestParam("photo")MultipartFile photo) {// 定义上传文件存放的路径
         String path = configProperties.getFileupload() + "uploadPhotos/";
         System.out.println(path);
         // 定义文件在上传路径中的文件夹名称
         File folder = new File(path);
         // 检测folder是否是文件夹，不是就创建
         if (!folder.isDirectory()) {
             folder.mkdirs();
          }
          try {
            // 获取文件的原始名称
             String photoName = idCardFront.getOriginalFilename();            
             // 文件保存操作
             photo.transferTo(new File(folder, photoName));             
             // 访问的url
             String basePath = request.getScheme() + "://" + request.getServerName() + ":" + request.getServerPort() + request.getContextPath();
             String photoPath = basePath + configProperties.getStaticAccessPath().substring(0, configProperties.getStaticAccessPath().lastIndexOf("/") + 1) + "uploadPhotos/" + photoName ;       
             System.out.println(basePath);
             System.out.println(photoPath );
             return R.ok();
          } catch (IOException e) {
             return R.error();
         }
}
