批量上传

@PostMapping("/uploadStrategyBatch")
public Rep<List<String>> uploadStrategyBatch(@RequestParam("file") MultipartFile[] file, @RequestParam("path") String path, HttpServletRequest httpServletRequest ) throws IOException, BasicException {
     return Rep.ok(fileService.uploadStrategyBatch(file, path, httpServletRequest));
}

最主要的就是把文件往这个 file 里面塞，你觉得这样会覆盖？其实并不会，这就是批量上传。

let fd = new FormData();
for (let i = 0; i < files.length; i++) {
    fd.append('file', files[i])
}
