當我指定一個休眠生成它自己的連接表

Question

我指定@JoinTable爲@ManyToMany，以便我可以指定表，列和外鍵的名稱。

Hibernate似乎正在生成我的地雷，但它仍然試圖生成它自己的。

下面是有問題的@ManyToMany的實體。僅包含實體的相關代碼。

@Entity 
@Table(name = "DAMAGE") 
public class DamageReport { 

    @Id 
    @GeneratedValue(strategy = GenerationType.AUTO, generator = "DAMAGE_ID_GENERATOR") 
    @SequenceGenerator(name = "DAMAGE_ID_GENERATOR", sequenceName = "DAMAGE_ID_SQ") 
    @Column(name = "DAMAGE_ID") 
    private Long id; 

    //...Bunch of other fields 

    @ManyToMany 
    @JoinTable(name = "BOARD_MEMBER_DAMAGE_REPORTS", joinColumns = { 
      @JoinColumn(name = "DAMAGE_REPORT_ID") }, inverseJoinColumns = { 
        @JoinColumn(name = "BOARD_MEMBER_ID") }, foreignKey = @ForeignKey(name = "DAMAGE_REPORT_ID_FK"), inverseForeignKey = @ForeignKey(name = "BOARD_MEMBER_ID_FK")) 
    private Set<BoardMember> boardMembers; 
}

下面是其他實體在@ManyToMany。僅包含實體的相關代碼。

@Entity 
@Table(name = "BOARD_MEMBER") 
public class BoardMember { 

    @Id 
    @GeneratedValue(strategy = GenerationType.AUTO, generator = "BOARD_MEMBER_ID_GENERATOR") 
    @SequenceGenerator(name = "BOARD_MEMBER_ID_GENERATOR", sequenceName = "BOARD_MEMBER_ID_SQ") 
    @Column(name = "BOARD_MEMBER_ID") 
    private Long id; 

    @ManyToMany 
    public Set<DamageReport> damageReports; 
}

任何幫助是極大的讚賞。

Answer 1

另一側上使用的mappedBy完成雙向映射：

@ManyToMany(mappedBy = "boardMembers") 
public Set<DamageReport> damageReports;
