找不到Hibernate Table，MappingException和OssertionException

Question

我尝试将现有的PostgreSQL数据库映射到Hibernate，并且它已经有效，而我没有将每个子类添加到Hibernate

这是超类

@Entity
@Table(name = "place", schema = "public", catalog = "dbp")
@Inheritance(strategy = InheritanceType.JOINED)
public class PlaceEntity {
    private long id;
    private String name;
    private String url;
//    private CityEntity cityById;
    private ContinentEntity continentById;
    private CountryEntity countryById;

这是子类

@Entity
@Table(name = "city", schema = "public", catalog = "dbp")
@PrimaryKeyJoinColumn(name = "cityid", referencedColumnName = "id")
public class CityEntity extends PlaceEntity{   //WHEN I ADD extends PlaceEntity , THE ERROR OCCURES
    private Long cityid;
    private Long ispartof;
  //private PlaceEntity placeByCityid;
    private CountryEntity countryByIspartof;
    private Collection<PersonEntity> peopleByCityid;
    private Collection<UniversityEntity> universitiesByCityid;

然后Intellij浏览以下例外：

我已经搜索了相关问题，但找不到任何解决方案。如果有人可以帮助我，我会很高兴：）

总是删除

时

extends PlaceEntity

它运行平稳，并映射ALS桌子，其中包括位置。

我已经在这个问题上投资了几天^^

对不起，这不是我的外语：）

我遇到了相同的问题（或非常类似的问题）。

Hibernate 5.2.17. -Final Postgresql sashitance.joined。

通过从映射中删除"目录"属性来解决它。尝试替换

@Table(name = "place", schema = "public", catalog = "dbp")

@Table(name = "place", schema = "public")

希望这会有所帮助。
