Question

我为@OneToMany关系创建了一个新表。以下是用于创建新表的liquibase脚本。新表包含其他两个表的ID。

<changeSet id="1" author="XXX">
   <comment>create table for UEN-ORG_C</comment>
   <createTable tableName="UEN_ORG_C">
      <column name="ORG_DTLS_ID_N" type="BIGINT">
         <constraints primaryKey="true" nullable="false" />
      </column>
      <column name="ORG_CODE_ID_N" type="BIGINT">
         <constraints  nullable="false" />
      </column>
   </createTable>
   <addForeignKeyConstraint
      constraintName="FK_ORG_DTLS"
      referencedTableName="ORG_DTLS"
      baseColumnNames="ORG_DTLS_ID_N"
      baseTableName="UEN_ORG_C"
      referencedColumnNames="ID_N" />
   <addForeignKeyConstraint
      constraintName="FK_ORG_CODE"
      referencedTableName="ORG_CODE"
      baseColumnNames="ORG_CODE_ID_N"
      baseTableName="UEN_ORG_C"
      referencedColumnNames="ID_N" />
</changeSet>

下面是实体类：

@Data
@Entity
@EqualsAndHashCode(of = {"id"})
@Table(name = "ORG_DTLS")
public class OrganizationDetails implements BaseEntity<Long> {

   @Id
   @GeneratedValue(strategy = GenerationType.IDENTITY)
   @Column(name = "ID_N")
   private Long id;

   @OneToMany
   @JoinTable(name = "UEN_ORG_C",
              joinColumns = {@JoinColumn(name = "ORG_DTLS_ID_N")},
              inverseJoinColumns = {@JoinColumn(name = "ORG_CODE_ID_N")})
   private List<OrgCode> orgCodes;
}

在保存ORG_DTLS的同时，我应该能够选择多个ORG_CODES，并且在创建ORG_DTLS时可以选择相同的ORG_CODES
示例：

 ORG_DTLS_ID_N ORG_CODE_ID_N 
      82             21 
      83             21 
      84             21 
      85             25 
      86             25 
      87             25 
      88             25

当我尝试将两个表的ID保存到具有单向关系的新表中时。保存数据时出现异常
