java - JPA/Hibernate (PSQL) 不创建连接表

标签 java hibernate postgresql jpa

出于某种原因，Hibernate 不为集合创建表， 下面列出了代码 基础实体

@MappedSuperclass
public abstract class BaseEntity implements Serializable {
    private static final long serialVersionUID = 1L;
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Basic(optional = false)
    @Column(name = "id", nullable = false, columnDefinition = "BIGINT UNSIGNED")
    protected Long id;
    @Column(name = "version")
    @Version
    private Long version;

这里还有两个继承自BaseEntity的类

@Entity
@AttributeOverride(name = "id", column = @Column(name = "route_id",
        nullable = false, columnDefinition = "BIGINT UNSIGNED"))
public class Route extends BaseEntityAudit {

    @ElementCollection
    private Collection<Point> routePoints = new ArrayList<Point>();

    @OneToMany(cascade = CascadeType.ALL)
    @JoinTable(name = "route_events")
    private Collection<Event> routeEvents = new ArrayList<Event>();

    @OneToMany(cascade = CascadeType.ALL)
    @JoinTable(name = "route_comments")
    private Collection<Comment> comments = new ArrayList<Comment>();

@Entity
@AttributeOverride(name = "id", column = @Column(name = "event_id",
        nullable = false, columnDefinition = "BIGINT UNSIGNED"))
public class Event extends BaseEntityAudit {
    @Embedded
    private Point point;

    @OneToMany(cascade = CascadeType.ALL)
    @JoinTable(name = "event_comments")
    private Collection<Comment> comments = new ArrayList<Comment>();

persistence.xml 已经有这个属性 name="hibernate.hbm2ddl.auto"value="create-drop"/>

当我检查 PG 管理员时，缺少诸如 route_events 之类的表不存在。 感谢您的帮助
