我需要你的帮助,使用@ElementCollection注释在两个表的Hibernate中映射关系.

第一个是父
表表名:父
数据库列

KEY1         Char      (first primary key field)
KEY2         Char      (second primary key field)
DESCRIPTION  Char
DEPENDENTID  BigInt

第二个是依赖表
TableName:Dependent
DB Columns

PARENTID     BigInt    (first primary key field)
CODE         Char      (second primary key field)
FIELD1       Char
FIELD2       Char

我需要使用@EmbeddedId注释为两个表定义PK,所以我创建了两个类:

@Embeddable
public class ParentPK implements Serializable
{
   @Column(name="K1")
   private String iK1;
   @Column(name="K2")
   private String iK2;
  // I omit the constructor, getter, setter, equals, hashcode method 
}

@Embeddable
public class DependentPK implements Serializable
{
  @Column(name="PARENTID")
  private String iParentId; …
