Content-Type 'multipart/form-data;boundary=----------------------------------------380009095894841063803635;charset=UTF-8' 是不支持

Question

用户实体：

package com.example.imageuploading.entity;

import jakarta.persistence.*;
import lombok.*;
import org.springframework.web.multipart.MultipartFile;

@Entity
@Table(name="profile")
@Data
@AllArgsConstructor
@NoArgsConstructor
@ToString
@EqualsAndHashCode
public class User {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @Column(name = "id")
    private int id;

    @Column(name = "name")
    private String name;

    @Column(name = "email")
    private String email;

    @Column(name = "image")
    private String image;
}


package com.example.imageuploading.dto;

import jakarta.persistence.Column;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.EqualsAndHashCode;
import lombok.NoArgsConstructor;
import org.springframework.web.multipart.MultipartFile;

@Data
@AllArgsConstructor
@NoArgsConstructor
@EqualsAndHashCode
public class UserDto {
    private String name;

    private String email;

    private String image;
}




package com.example.imageuploading.config;

import com.cloudinary.Cloudinary;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import java.util.HashMap;
import java.util.Map;
@Configuration

public class UserConfig {

    private final String CLOUD_NAME="dxexmssdr";
    private final String API_KEY="122877238947871";
    private final String API_SECRET="loBifIQQWeIJr8G1y5A387BOSaU";

//
//    @Value("${cloudinary.cloudName}")
//    private String cloudName;
//
//    @Value("${cloudinary.apiKey}")
//    private String apiKey;
//
//    @Value("${cloudinary.apiSecret}")
//    private String apiSecret;

    @Bean
    public Cloudinary cloudinary(){
        Map<String,String> config=new HashMap<>();
        config.put("cloud_name",CLOUD_NAME);
        config.put("api_key",API_KEY);
        config.put("api_secret",API_SECRET);
        return new Cloudinary(config);
    }

}





package com.example.imageuploading.service;

import com.cloudinary.Cloudinary;
import com.cloudinary.utils.ObjectUtils;
import com.example.imageuploading.dto.UserDto;
import com.example.imageuploading.entity.User;
import com.example.imageuploading.repo.UserRepo;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.web.multipart.MultipartFile;

import java.io.IOException;
import java.util.Map;

@Service
public class UserService {

    @Autowired
    private UserRepo userRepo;

    @Autowired
    Cloudinary cloudinary;

    public String addNewUser(UserDto userDto) throws IOException {
        String imageUrl = null;
        if (userDto.getImage()!= null && !userDto.getImage().isEmpty()) {
            Map uploadResult = cloudinary.uploader().upload(userDto.getImage(), ObjectUtils.emptyMap());
            imageUrl = (String) uploadResult.get("secure_url");
        }

        User user = new User();
        user.setName(userDto.getName());
        user.setEmail(userDto.getEmail());
        user.setImage(imageUrl);
        userRepo.save(user);
        return "user successfully";
    }

}

错误是：
