First, I define a user interface that can be taken out from it. The code is as follows. The user must set its role and the group of groups in addition to a variety of different attributes.
A AbstractUser then processes the User commonality. All methods of acquiring properties are implemented. Users can inherit the properties to be defined according to the implementation of the properties that you want to define. (Because users of each system will have different Properties, so keep abstract classes for users their own extensions). As long as initialization variables Description, Name, Group, ID, Prop, Role, PropMAP can be initialized.
Finally, a class userimum is defined to implement a specific user for a User for general users. It is not recommended to use UserImpl directly, because later versions may overwrite the class. If you want to use, you can rename it You can.
This part involves a resourcelib class, which is in the class that I defined by the storage of various resource configurations, which can be used directly.
