                if (file.getBoolean("success")) {

                }
            }
            String project_id = tpmProjectService.save(map);
            return Result.success("system.success",project_id);
        } catch (Exception e) {
            return Result.error(e.getMessage());
        }
    }

选择上传文件，提交后，表单其他数据与文件数据可以正常获取及保存！
但是如果不选择上传文件，提交后报错如下：

如果是下面这样接收

@AdaptBy(type = UploadAdaptor.class, args = {"ioc:imageUpload"})
    @At("/addDo")
    @Ok("json")
    @RequiresAuthentication
    @SLog(tag = "项目表", msg = "${args[0].id}")
    public Object addDo(@Param("..") NutMap map, @Param("Filedata") TempFile image, HttpServletRequest req, AdaptorErrorContext err) {
        try {
            if(image!=null) {
                NutMap file = Utils.fileSave(image, "", true);
                if (file.getBoolean("success")) {
                    map.put("image", file.getString("path"));
                }
            }
            String project_id = tpmProjectService.save(map);
            return Result.success("system.success",project_id);
        } catch (Exception e) {
            return Result.error(e.getMessage());
        }
    }

不上传文件提交，err有错误信息，但是map是null

前端拦截一下，不选文件不给提交

我的业务逻辑需要不选择文件也可以提交呀！比如只修改表单数据，文件不修改，还是第一次的文件（就不需要重新上传）。
不过这个错误信息在我设置form的 enctype="multipart/form-data"后正常了，不太清楚原因！

前端用什么js插件做的？

layui的upload
