脱机同步文件:上传ArrayList或在for循环中上传

Question

我基本上是一个Java开发人员，只有Android开发的基本信息。我已经开发了一个web端点，它可以接受一个文件和一些其他参数。java代码是

@RequestMapping(path = "/api/beneficiary/initial/inspection/upload", method = RequestMethod.POST, produces = "application/json")
public @ResponseBody String uploadInitialInspectionPhoto(@RequestParam(value = "uploadImg") MultipartFile file,
        @RequestParam("hdId") Long hdId, @RequestParam("toRegId") String toRegId,
        @RequestParam(value = "remark", required = false) String remark,
        @RequestParam(value="latitude")String latitude,
        @RequestParam(value="longitude")String longitude) {
//.... Method Code
}

我的Android开发人员说，在异步后台线程上上传10个文件需要10分钟，因为它必须点击URL 10次。她建议我将API改为接受ArrayList。即，将接口更改为

@RequestMapping(path = "/api/beneficiary/initial/inspection/upload", method = RequestMethod.POST, produces = "application/json")
public @ResponseBody String uploadInitialInspectionPhoto(@RequestParam(value = "uploadImg") MultipartFile[] files,
        @RequestParam("hdId") Long[] hdIds, @RequestParam("toRegId") String[] toRegIds,
        @RequestParam(value = "remark", required = false) String[] remarks,
        @RequestParam(value="latitude")String[] latitudes,
        @RequestParam(value="longitude")String[] longitudes) {
     for (int idx =  0; idx < hdIds.length; idx++)
     {
        //... Same code as in current method
        officerSvc.save(.....)
     }
} 

注意复数形式和[]

我的基本问题是:是否建议更改api以接受ArrayList/Array而不是单个实例，以提高上传的性能并发挥其优点？事实还是虚构？

是的，它将节省在客户端和服务器之间建立连接的时间。但不是很多，可能是1-2秒。
