 注意：该模式需要构建资源包
 
-- LocationServices : 资源定位的实例类。
-  
-  (1) 默认的资源定位服务类（DefaultLocationServices）
-  
-  (2) 可寻址的资源定位服务类（AddressLocationServices）
-  
-  (3) 开发者自定义的资源定位服务类，需要提供实现ILocationServices接口的实例类。
-  
 - DecryptionServices : 如果资源包在构建的时候有加密，需要提供实现IDecryptionServices接口的实例类。
 
 - QueryServices：内置资源查询服务接口。
