Invocation of init method failed;
nested exception is org.hibernate.MappingException:
Repeated column in mapping for entity: com.justinmobile.lticket.domain.EcUserConsInfo column: ADD_USER (should be mapped with insert="false" update="false")
异常原因:
我在EcUserConsInfo实体中建立了一个对MticketUserinfo对象的引用。其中的name对应数据库本表中名称(ec_usercons_info表要引用MTICKET_USERINFO的id从而最终找到名称)。
@ManyToOne
@JoinColumn(name="ADD_USER")
@Cascade(value={CascadeType.PERSIST,CascadeType.MERGE})
public MticketUserinfo getMticketUserinfo() {
return mticketUserinfo;
}
我之前建立了一个 addUser的字段其映射为(name="ADD_USER"),现在我是通过建立实体MTICKET_USERINFO的引用,那么就不在需要建立数据库表中对应的addUser字段了。去掉即可。
PS:关于是对象映射表还是从表建立域对象,个人觉得从表到域对象好。
