the Agreement over the configuration (CoC.
A: convention over configuration, also known as contract-based programming, is a software design paradigm designed to reduce the number of decisions that software developers need to make. Essentially, developers only need to specify parts that do not conform to the conventions in the application. For example, if there is a class named Sale in the model, the corresponding table in the database will be named s

Background
In recent years in the game industry, there have been a variety of roll dress games, including page tours, hand tours, H5 games and so on. The difference between the game and the big dress game is that the number of players at the same time, the big game is a lot of users play together, even dozens of millions of gamers. And the game is ge

3. The Controller uses any non-setter and getter functions to process requests.
4. The Controller uses the function return value to control the redirection. Only one Controller can be redirected to another Controller. One Controller cannot correspond to two views.
5. The Controller uses setter to automatically assemble Model dependencies, including dependencies between models.
6. Session parameters, such as loginUserId, are also injected to the Controller through setter. If a re
