【JFinal】關於Model的繼承

1. 繼承Model當然需要先看一下Model的代碼

   public abstract class Model<M extends Model> implements Serializable {
       ...
   }

2. 發現Model的泛型有繼承關系，那么子類如下寫

   public class BaseModel<M extends BaseModel<M>> extends Model<M> {
       ...
   }

3. 大功告成

   public class User extends BaseModel<User > {
       ...
   }
