如何在Spring中通过@RequestParam进行迭代？
如何在Spring中通过@RequestParam进行迭代？
提问于 2017-01-07 05:59:47
我正在用Spring构建一个API，我有一个简短的问题：
在对它们执行一些逻辑之前，我想对下面的这些参数执行检查，看看它们是否包含值。
我是Spring的新手--有没有什么办法可以把这些值“获取”到某种数据结构中，这样我就可以执行检查了？
@RequestParam(value = "video") MultipartFile video,
@RequestParam(value = "pictureOne") MultipartFile pictureOne,
@RequestParam(value = "pictureTwo") MultipartFile pictureTwo,
@RequestParam(value = "pictureThree") MultipartFile pictureThree,
@RequestParam(value = "pictureFour", required = false) MultipartFile pictureFour,
@RequestParam(value = "pictureFive", required = false) MultipartFile pictureFive,
@RequestParam(value = "pictureSix", required = false) MultipartFile pictureSix,
@RequestParam(value = "pictureSeven", required = false) MultipartFile pictureSeven,
@RequestParam(value = "pictureEight", required = false) MultipartFile pictureEight,
@RequestParam(value = "pictureNine", required = false) MultipartFile pictureNine,
@RequestParam(value = "pictureTen", required = false) MultipartFile pictureTen)回答
