After defining User, Group, Role, I define the rules for permission judgment.
First define the rule interface, see Rule.java.rule only to do one thing to determine if the user has permission.
Then I realized a Rule, see RuleImpl.java.
This part involves an Input class, which is an input class, interface such as Input.java. This can use various way data (HTTP, XML, SOAP ...) as input data by inheriting the interface.
Permission is the authority class, which will be introduced below.
