最近用JPA遇到这样一个问题：Repeated column in mapping for entity: com.ketayao.security.entity.main.User column: org_id (should be mapped with insert="false" update="false")
这个错误是由实体类引起的，我一开始是这样写的：
@Column
private long orgId;
@ManyToOne
@JoinColumn(name="orgId")
private Organization organization;
在这里get和set方法就省略了。
修改为下面这样就好：
@Column(insertable=false,updatable=false)
private long orgId;
@ManyToOne
@JoinColumn(name="orgId")
private Organization organization;
玩转JPA(一)---异常：Repeated column in mapping for entity/should be mapped with insert="false" update="fal
