文件上傳接口傳參規范

單個文件上傳

@RequestBody與文件類型參數不兼容：

org.springframework.web.HttpMediaTypeNotSupportedException: Content type 'multipart/form-data;

@PostMapping("/fileUpload")
public void method(@RequestBody @Validated FileMultipartUploadReqVO reqVO,
                   @RequestParam(value = "file") MultipartFile file) {}
//把@RequestBody去掉
@PostMapping("/fileUpload")
public void method(@Validated FileMultipartUploadReqVO reqVO,
                   @RequestParam(value = "file") MultipartFile file) {}

批量文件上傳

@PostMapping("/fileUpload")
public void method(@Validated FileMultipartUploadReqVO reqVO,
                   @RequestParam(value = "fileList") List<MultipartFile> fileList) {}
//注意：前端此時批量上傳時需要將fileList並列傳到body的form-data中，並不是像后端一樣放到一個集合中
