我的数据库包含应用程序,每个应用程序都有功能。 每个应用必须至少有一个功能,并且每个功能可以与多个应用相关联。
应用的主要类:
@Entity
@Table(name = ("apps"))
public class AppEntity implements Serializable {
@Id
@Column(name = ("app_id"), nullable = false)
private String appId;
@Column(name = ("app_name"), nullable = false)
private String packageName;
@OneToMany(mappedBy = "appEntity", fetch = FetchType.EAGER, cascade = CascadeType.ALL)
private List<AppFeatureEntity> appFeatures = new ArrayList<>();
特征类别:
@Entity
@Table(name = ("app_features"))
public class AppFeaturesEntity implements Serializable {
@EmbeddedId
protected AppFeaturesEntityKey keys;
@ManyToOne(fetch=FetchType.LAZY, optional = false)
@JoinColumn(name = ("app_id"), insertable = false, updatable = false)
@JsonIgnore
private AppEntity appEntity;
PK课:
@Embeddable
public class AppFeaturesEntityKey implements Serializable {
@Column(name = ("feature_id"), nullable = false)
private String featureId;
@Column(name = ("app_id"), nullable = false)
private String appId;
我正在使用 ModelMapper 根据更新后的实体更新旧实体,当我尝试调用 JpaRepository.saveAll(List<AppEntity>)
时出现错误:
Multiple representations of the same entity [....AppFeaturesEntity#...AppFeaturesEntityKey@32d2bdd] are being merged
