问：

当我想使用http将文件从浏览器传输到spring mvc时，会出现错误。如果我删除过滤器，就会被接受。我推断过滤器中发生了错误。以此类推，如果我删除操作系统中的临时文件，它会显示该文件在我的程序运行时被占用。 我的操作系统 Windows 11，但是 Anthor Windows 10 会出现同样的问题。谢谢。此错误消息。

@RestController
@RequestMapping("/api/ecm")
@Slf4j
public class EcmController {

    @Autowired
    CadHelper cadHelper;


    @Parameter(name = "file", description = "文件", required = true, in = ParameterIn.DEFAULT, ref = "file")
    @PostMapping("/2dimport")
    ResponseDTO<String> upload(@RequestParam("file") @RequestPart("file") MultipartFile file) {
        String s = cadHelper.import2DModel(file);
        return ResponseDTO.success(s);
    }
}

我可以得到正确的结果。
