java获取spring注解的实体_Spring 注解实体类中非数据库字段属性

今天要给一个实体类添加一个List集合属性！

private List childList = new ArrayList();

写完后get/set方法一写，启动就报错：

org.hibernate.MappingException: Could not determine type for: java.util.List, at table: T_REVERTS, for columns: [org.hibernate.mapping.Column(childList)]

解决办法：在属性的get方法上加上一段注解标识它是临时属性，不是数据库字段就OK

@Transient

public List getChildList() {

return childList;

}

public void setChildList(List childList) {

this.childList = childList;

}

记得导入的是：

import javax.persistence.Transient;
