 A controller registered to a drogon framework will have at most only one instance and will not be destroyed during the entire application run, so users can declare and use member variables in the controller class. Note that when the handler of the controller is called, it is in a multi-threaded environment (when the number of IO threads of the framework is configured to be greater than 1), if you need to access non-temporary variables, please do the concurrent protection work.

 It should be noted that the controller of each table is designed to be composed of a base class and a subclass. Among them, the base class and the table are closely related, and the subclass is used to implement special business logic or modify the interface format. The advantage of this design is that when the table structure changes, users can update only the base class without overwriting the subclass(by setting the `generate_base_only` option to `true`).
