Caused by: org.hibernate.MappingException: Repeated column in mapping for entity: com.yyf.entity.Cus_字段

异常大意：

　　一个pojo中不能有两个属性同时映射到一个数据库字段上

以下是我犯的错误

Caused by: org.hibernate.MappingException: Repeated column in mapping for entity: com.yyf.entity.Cus_entity_02

解法（1）

　　把custName改正为custMobile

解法（2）

　　在重复的字段添加 insert=”false” update=”false”

如图
