Repeated column in mapping for entity: com.hibernateOut.entity.Orderitem column: oid (should be mapped with insert=“false” update=“false”)

原因:
這是因為在Hibernate 一對多關係新增中 重複對映實體類的列
解決方法:
在property 中加入屬性:insert=“false” update=“false”
<property name="oid" type="java.lang.Integer" column="oid" insert="false" update="false"/>
