1.后端代码部分：

@RestController
@RequestMapping("/file")
public class FileController {
    private final String UPLOAD_PATH = "D:/OBS/";//这里写上你需要上传的路径（模拟服务器）

    @PostMapping("/upload")
    public ResponseEntity uploadFile(@RequestParam MultipartFile file) {
        // ... File upload logic ...
        if (file.isEmpty()) {
            return new ResponseEntity<>("文件不能为空", HttpStatus.BAD_REQUEST);
        }
        try {
            byte[] bytes = file.getBytes();
            Path path = Paths.get(UPLOAD_PATH + File.separator + file.getOriginalFilename());
            Files.write(path, bytes);
            return new ResponseEntity<>("文件上传成功", HttpStatus.OK);
        } catch (IOException e) {
            e.printStackTrace();
            return new ResponseEntity<>("文件上传失败", HttpStatus.INTERNAL_SERVER_ERROR);
        }
    }
