Spring Data Rest：如何發送包含請求的多部分文件正文

Question

我想構建一個用戶註冊的API，其中我需要用戶基本信息和他/她的個人資料圖片，所以我非常困惑，我該如何實現這個 ！我已經做了控制，並要求一個身體，但是當我訪問此API它給了我錯誤的"Unsupported Media Type"當我設置的內容類型爲multipart/form-data那麼它給出了一個錯誤： the request was rejected because no multipart boundary was found

請幫助我如何發送用戶信息和用戶照片BOTH在修訂SAME請求

：控制器

@RequestMapping(method = RequestMethod.POST, value = "createRider") 
public @ResponseBody ResponseEntity<?> createRider(
     @RequestBody CreateRider createRider,Authentication authentication, 
     PersistentEntityResourceAssembler assembler,@RequestPart(value = "profilePic", required = false) MultipartFile file) { 

    if (authentication != null && authentication.getPrincipal() != null) { 
     Collection<? extends GrantedAuthority> authorities = authentication.getAuthorities(); 
     boolean authorized = authorities.contains(new SimpleGrantedAuthority("rights")); 
     if (authorized==true) 
      userService.createNewRider(createRider); 
     else 
      return ResponseEntity.status(HttpStatus.SC_CONFLICT).body("Logged In user is not admin"); 
    } else { 
     // Access denied 
     throw new AccessDeniedException("Not logged in"); 
    } 
    return ResponseEntity.ok("Rider Created"); 
} 

createRider.java

public class CreateRider { 

    private String email; 

    private String name; 

    private String password; 

    private String contactNumber; 

    private String cnicNumber; 

    private String drivingLicense; 

    private String reference; 

    private MultipartFile file; 
    ..getters nad setters 
    } 

userService.createNewRider

public void createNewRider(CreateRider createRider) { 
     Group group=groupRepo.findOne(Constants.RIDER_USER_GROUP); 
     User user=new User(); 
     user.setGroup(group); 
     user.setEmail(createRider.getEmail()); 
     user.setName(createRider.getName()); 
     user.setPassword(createRider.getPassword()); 
     user.setContactNumber(createRider.getContactNumber()); 
     user.setCnicNumber(createRider.getCnicNumber()); 
     user.setDrivingLicense(createRider.getDrivingLicense()); 
     user.setReference(createRider.getReference()); 
     userRepo.save(user); 
     RiderLocation riderLocation=new RiderLocation(); 
     riderLocation.setRider(user); 
     riderLocationRepo.save(riderLocation); 
     ///User Photo 
     UserPhoto userPhoto=photoService.createUserPhoto(createRider.getFile(), user.getId()); 
     userPhotoRepo.save(userPhoto); 



    }

您可以通過添加以下到控制器

@RequestPart(value = "profilePic", required = false) MultipartFile profilePic

所以控制器方法變得

進行個人資料的圖片作爲 MultipartFile

import org.springframework.web.bind.annotation.RequestPart; 
import org.springframework.web.multipart.MultipartFile; 

@RequestMapping(method = RequestMethod.POST, value = "createRider") 
public @ResponseBody ResponseEntity<?> createRider(
     @RequestPart CreateRider createRider,Authentication authentication, 
     PersistentEntityResourceAssembler assembler, @RequestPart(value = "profilePic", required = false) MultipartFile profilePic) { 

}
