uploadPicture

1.上传图片需要用到（

HttpServletRequest httpServletRequest, @RequestParam(required = false) MultipartFile[] file）添加@RequestParam(required = false)，没有强制一定要传图片的意思

String path = "/res/notification/campaign"; //定义一个路径

// 生成图片名

String filename = "campaign_" + RandomStringUtils.randomAlphanumeric(8); //利用随机数，生成长度为8的随机数

String fileImageName = fileUtils.requestUploadImages(file[0], path, filename); //调用图片上传的方法，将图片名，图片，图片路径等参数带上

/**

* @param file 文件

* @param path 路径

* @param filename 文件名不含后缀名

* @return uploadfileName 需保存数据

@SuppressWarnings({ "unlikely-arg-type", "unused" })
