Spring Boot Jhipster映像上傳不起作用

Question

我想上傳圖片以及更多來自角度的內容。 這是VM對象：

public class UserPictureVM {

    private MultipartFile file;

    private String type;

    private String coverPosition;

這是rest方法：

 @PostMapping("/user/upload-picture")
 @Timed 
 public ResponseEntity<Void> uploadUserPicture(@RequestBody UserPictureVM userPicture){

這是提交表單的Angular方法：

saveCoverImage() {
    const formData: FormData = new FormData();

    formData.append('coverPosition', '0, 0');
    formData.append('file', this.coverForm.file);
    formData.append('type', 'cover');

    this.profileService.uploadImages(formData)
      .subscribe(res=> {
        console.log(res);
      })
  }

但我得到錯誤：

Resolved exception caused by Handler execution: org.springframework.web.HttpMediaTypeNotSupportedException: Content type 'multipart/form-data;charset=UTF-8' not supported

您正在提交帶有3個請求參數的表單。 因此，您應該將控制器方法簽名更改為此：

  public ResponseEntity<Void> uploadUserPicture(
      @RequestParam("coverPosition") String coverPosition,
      @RequestParam("file") MultipartFile file,
      @RequestParam("type") String type)
