当我上传一个图像时，我得到一个image_id，当我使用该id上传产品时，上传成功，但product表中的image_id字段为空。
我已经提供了下面的代码，如果你无法重现这个问题，你可以在这里找到代码https://github.com/My-Portfolio-Projects/FoodBox.git
这是产品实体

@Getter
@Setter
@NoArgsConstructor
@AllArgsConstructor
@Entity
@Table(name = "products", schema = "foodbox")
public class Product {
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Id
    @Column(name = "product_id")
    private int productId;
    @Basic
    @Column(name = "name")
    private String name;
    @Basic
    @Column(name = "description")
    private String description;
    @Basic
    @Column(name = "price")
    private BigDecimal price;
    @Basic
    @Column(name = "quantity_in_stock")
    private int quantityInStock;

    @OneToOne(cascade = CascadeType.ALL)
    @JoinColumn(name = "image_id", referencedColumnName = "image_id")
    private Image image;
    
    
}

字符串
这是图像实体

@NoArgsConstructor
@Getter
@Setter
@Entity
@Table(name = "images", schema = "foodbox")
public class Image {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "image_id", nullable = false)
    private Integer id;

    @Column(name = "image_name", nullable = false)
    private String name;

    @Lob
    @Column(name = "image_data", nullable = false)
    private byte[] imageData;

    public Image(String name, byte[] data) {
        this.name = name;
        this.imageData = data;
    }

   

}

这是上传图像的控制器逻辑，它可以工作

//Part of ImageController.java
@PostMapping(value = "/image",consumes = MediaType.MULTIPART_FORM_DATA_VALUE )
   public ResponseEntity<Integer> createImage(@RequestPart("image") MultipartFile data) throws IOException {
       String name = data.getOriginalFilename();
       Image image = imageService.createImage(name, data.getBytes());
       return ResponseEntity.ok(image.getId());
       }

//Part of ImageService.java
public Image createImage(String name,byte[] data)  {
       
   Image image = new Image(name,data);
   return this.imageRepository.save(image);
   }

//Part of ImageRepository

   Image save(Image image);

这是控制器的逻辑上传一个新的产品，这也工程

//Part of ProductController.java
 @PostMapping(value="/products")
    public Product createProduct(@RequestBody Product product) {
        return productService.createProduct(product);
    }

//Part of ProductService.java
 public Product createProduct(Product product) {
        return productRepository.save(product);
    }

//Part of ProductRepository which extends CrudRepository
 @Override
    Product save(Product product);
