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！
[java]view plaincopyprint?
private List<Reverts> childList = new ArrayList<Reverts>();
写完后get/set方法一写，启动就报错：
[plain]view plaincopyprint?
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
[java]view plaincopyprint?
@Transient
public List<Reverts> getChildList() {
return childList;
}
public void setChildList(List<Reverts> childList) {
this.childList = childList;
}

记得导入的是：import javax.persistence.Transient;
