自定义注解

切面类

控制层

    /**
     * 服务对象
     */
    @Resource
    private UserService userService;

    @PostMapping(value = "uploadFileByEasyPoi")
    @MethodExporter
    @ApiOperation(value = "通过easypoi上传文件")
    public AjaxResult uploadFileByEasyPoi(@RequestPart MultipartFile file){
        userService.uploadFileByEasyPoi(file);
        return AjaxResult.success();
    }
