Generic Authentication

Apache License v2 Sources (SVN) Sources (browse) Javadoc Maven reports Maven repository

This package provides classes and interfaces that implements a generic authentication module: User, Permission, PermissionGroup, and Role. It also provides DAOs and controllers, implemented using Generic DAO and Generic Controller

This package is completely technology-independent and has no dependencies except Generic DAO, Generic Controller and the JPA ORM annotations.

All DAOs in this package are implemented in Generic Authentication-Hibernate.

Classes

User represents a single user in an application and it is meant to not be subclassed. Creating subclasses to represent different types of user is an approach that has a serious limitation: it does not support changing the type of a given user during application execution, at least not elegantly. That is why the Role class exists.

Role is an abstract class that represents some type of role that an User can have. Each User can have many Roles, but each Role instance belongs to a single User.

Generic Authentication supports user permissions through its Permission and PermissionGroup classes. Each User can be associated to any number of PermissionGroups. In addition, it is possible to remove specific Permissions from an User, through its removedPermissions property.
