Question

有复杂的对象，mongodb将其保存为一个对象。我尝试在JPA和Hibernate中创建相同的关系。 javax.persistence有@Emeded和@Embadable，但他们没有使用SynonymGroup中的列表。然后需要地图分隔表。

@Data
@Entity
@Table(name = "BASE_SYNONYM")  
public class BaseSynonym {
    @Id
    @Column(name = "WORD_ID")
    private String word;

    @OneToMany
    @JoinTable(name = "BASE_SYNONYM_SYNONYM_GROUP",
               joinColumns = @JoinColumn(name = "WORD_ID"),
               inverseJoinColumns = @JoinColumn(name = "DESCRIPTION_ID")
    )
    private List<SynonymGroup> synonymGroup;
}


@Data
@Entity
@Table(name = "SYNONYM_GROUP")
public class SynonymGroup {
    @Id
    @Column(name = "DESCRIPTION_ID")
    private String description;

    @ElementCollection
    @CollectionTable
    private List<String> words;
}

我认为这是错误的映射。例外：
