        String realPath = "d:\\files\\";

                    try {

                    } catch (IllegalStateException | IOException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }

                } else {
                    System.out.println("Wrongtype");
                    result.setSuccess(false);
                }

                result.setSuccess(false);
            }
        }
        return result;
    }

请求代码：

    @RequestMapping(value="insertExceptionPic",method=RequestMethod.POST)
    @ApiOperation("上传异常图片")
    @ResponseBody
    public Result<String> uploadExceptionPicture(@RequestParam("file") MultipartFile file)
    {
        return utils.ImageUpload(file);

    }

上传成功
