When the action method is invoked, it is necessary to reattach the updated object to the persistence context, making the changes permanent.
当调用该操作方法时，必须重新使已更新的对象与持久化上下文建立联系。

Uses native XML persistence to solve XML, object, and relational incompatibility.
使用本地XML持久化来解决XML，对象和关系数据库的不匹配性。
Object serialization is an easy way for implementing the repository's persistence since the DataMapRepository class, the contained data maps, and their elements are serializable.
对象序列化是实现存储库持久性的一种最简单的方式，原因是datamaprepository类、所包含的数据地图以及它们的元素都是可序列化的。
For example, if the mapping attribute of the DataSource object is not set, the data source might not act as the data source in the container-managed persistence (CMP).
例如，如果未设置DataSource对象的mapping属性，则数据源的行为方式不会与容器管理的持久性(CMP)中的数据源相同。

Stateless: Your classes must extend LightEntity or implement ILightEntity which enables the persistence information to be stored on the cloned object (no information is left on the server).
无状态：对象类型必须继承自lightentity，或者实现ILightEntity接口，这样持久化信息才会被保存在克隆出来的对象上面(服务器上不保留相关信息)。
