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)。
The service layer object will be treated as a stateless interface to which the CRUD operations can be delegated.
服务层对象将作为无状态的接口对待,CRUD操作可以委托给该接口。
Object caching and pooling: the application server automatically pools stateless session beans at the server level, reducing the amount of time spent in object creation and garbage collection.
对象高速缓存和合用:应用程序服务器自动在服务器级合用无状态会话bean,这减少了花在对象创建和垃圾收集上的时间。
