JPA/Hibernate 无法在 spring 引导中生成主键

Question

我从基本实体继承了公共属性，id 是公共属性之一，我使用的是生成策略标识。

我正在尝试保存子实体，但遇到 Hibernate 无法填充主键的错误。

@Data
@MappedSuperclass
public class BaseImagesAndLayout {

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

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

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

 }

子实体：

@Entity
@Data
@Table(name="VEHICLE_HEADER_IMAGES")
public class VehicleHeaderImage extends BaseImagesAndLayout {

    @Column(name = "MODEL_CODE")
    private String modelCode;
}

保存实体：

    for(S3Object object:AppUtil.skipFirst(objList)) {
                vehicleHeaderImage=new VehicleHeaderImage();
//              response = s3Service.downloadDocument(bucketName,object.key());
                response =s3Service.getDocPresignedUrl(bucketName, object.key(), null); 
                System.out.println("rsponse----"+response);
                System.out.println("filename----"+FilenameUtils.removeExtension(FilenameUtils.getName(object.key()))+ ""+FilenameUtils.getExtension(object.key()) );
                vehicleHeaderImage.setDisplayName(AppUtil.removeFileExtension(AppUtil.getFileNameFromPath(object.key())));
                vehicleHeaderImage.setFileName(vehicleHeaderImage.getDisplayName());
                vehicleHeaderImage.setModelCode("");
                vehicleHeaderImage.setS3BucketKey(object.key());
                vehicleHeaderImage.setS3PresignedUri(response.getS3DocPresignedUrl());
                headerImgRepository.save(vehicleHeaderImage);
//              vehicleHeaderImage.setS3PresignedExpDate(response.getS3DocPresignedUrlExpDt());
            }

例外：

通常 hibernate 负责生成 id 列，但我无法在这里弄清楚，还有一点需要注意的是，我使用 liquibase 创建了这些表。

我正在使用 JPA 进行粗加工。
