JPA /休眠（PSQL）不创建joinedtable

Question

出于某种原因，Hibernate不创建类别表， 下面列出的代码 BaseEntity

@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; 

这里是从BaseEntity

继承其它两个类

@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中已将此属性名= “hibernate.hbm2ddl.auto” 值= “创建降”/ >

当我检查PG管理员错过了表，如route_events不存在。 感谢您的帮助

Answer 1

我应该把重点放在“与UNSIGNED”有关的PostgreSQL的语法错误。

Why unsigned integer is not available in PostgreSQL?
