two DB service have same method，how to

使用接口建立服务，我设计了一个TInterfacedObjectWithCustomCreate为基类的ImplementationClass。现在，我有两个不同root的DB，aDB,bDB.分别注册了这个ImplementationClass。在ImplementationClass的方法里，我怎么分别这是运行在aDB或者是bDB？或者说，我在方法的运行期间，怎么样获取它注册的工厂类和TRESTSERVERDB

Using an interface to create a service, I designed an ImplementationClass with TInterfacedObjectWithCustomCreate as the base class. Now, I have two different root DBs, aDB and bDB. Each has registered this ImplementationClass. In the ImplementationClass method, how can I distinguish whether this is running on aDB or bDB? In other words, how do I obtain the registered factory class and TRESTSERVERDB of a method during its operation

It works, but I may inject the information in the class itself implementing the service, if possible.

When I called an interface service in a long running thread on the server, an error occurred. Some objects are not initialized
