Problem reading requestparam in controller

Question

The request params are shown in the network but the second param (fileId) is received as null in the controller. The request returns 400 bad request.

@PostMapping(path = "/uploadFile")
public ResponseEntity<ServiceResponse> upload(
        @RequestParam(value = "id") Long userId,
        @RequestParam(value = "fileId") Long fileId,
        @RequestPart(value = "file") MultipartFile... file) {

    // 
        return ResponseEntity.ok(serviceResponse);
}

request URL: (the file is sent in the body: formData) http://localhost:8080/api/upload?id=9999&fileId=101

Answer 1

好吧，您能否至少显示您的请求或 URL？

Answer 2

你的 URL 应该是http://localhost:8080/api/uploadFile?id=9999&fileId=101而不是http://localhost:8080/api/upload?id=9999&fileId=101因为你已经提到了作为 uploadFile 的路径
