Hibernate 使用sql类型字符的多列休眠一对多单向关系

hibernate jpa

Hibernate 使用sql类型字符的多列休眠一对多单向关系,hibernate,jpa,Hibernate,Jpa,我有两个实体名为“Padre”和“Figlio” 神父是主人，菲利奥是孩子 Padre的主键有两列，PADREK1和PADREK2，都是CHAR（20） Figlio的主键有四列： PADREPADREK1（国外）字符（20） PADREPADREK2（国外）字符（20） FIGLIOK1字符（20） FIGLIOK2字符（20）这是我的实体类的代码 public class PadreBean extends BaseEntityBean3 implements Serializable

我有两个实体名为“Padre”和“Figlio” 神父是主人，菲利奥是孩子 Padre的主键有两列，PADREK1和PADREK2，都是CHAR（20） Figlio的主键有四列： PADREPADREK1（国外）字符（20） PADREPADREK2（国外）字符（20） FIGLIOK1字符（20） FIGLIOK2字符（20）

这是我的实体类的代码

public class PadreBean extends BaseEntityBean3 implements Serializable { @EmbeddedId PadrePK iPadrePK; @Column(name = "DESCRIPTION") private String iDescription; @Column(name = "ABSUNIQUEID") private long iABSUniqueId; @OneToOne(fetch = FetchType.EAGER, cascade = CascadeType.ALL) @JoinColumns( { @JoinColumn(name = "ABSOUTQUEUENAME", nullable = true) }) private ABSOutQueueBean iAbsOutQueueBean; @OneToMany(fetch = FetchType.LAZY) @JoinColumns({ @JoinColumn(name = "PADREPADREK1", referencedColumnName = "PADREK1"), @JoinColumn(name = "PADREPADREK2", referencedColumnName = "PADREK2") }) List iFiglioBeans; ...... 公共类PadreBean扩展BaseEntityBean3实现可序列化 { @嵌入ID PadrePK-iPadrePK； @列（name=“DESCRIPTION”）私有字符串描述； @列（name=“ABSUNIQUEID”）私人长假； @OneToOne（fetch=FetchType.EAGER，cascade=CascadeType.ALL） @连接柱( { @JoinColumn（name=“ABSOUTQUEUENAME”，nullable=true） }) 私有绝对排队bean； @OneToMany（fetch=FetchType.LAZY） @连接柱({ @JoinColumn（name=“padreparek1”，referencedColumnName=“PADREK1”）， @JoinColumn（name=“padrepredek2”，referencedColumnName=“PADREK2”） }) 列出伊法利奥贝人； ...... iFiglioBeans是儿童的集合

问题是：如果Padre的两个主键列都使用全部20个字符填充，则所有字符都可以正常工作； id padre的主键列未完全填充Hibernate加载集合但加载后，它会清除其内容

我已激活Hibernate日志记录，当我的代码访问children集合时，我看到：
