17 * The authorization package provides an authorization service that can be used to
18 * check whether users have the rights to perform certain operations:
20 * <img src="doc-files/Class_Diagram__org.wamblee.security.authorization__main.jpg"/>
23 * {@link AuthorizationService} is the entry point. There is one POJO based implementation
24 * {@link DefaultAuthorizationService}. In addition, there is {@link org.wamblee.security.authorization.jpa.JpaAuthorizationService}
25 * which caches an authorization service for efficiency (i.e. {@link DefaultAuthorizationService} is an entity);
27 * The {@link DefaultAuthorizationService} uses a number of authorization rules to determine
28 * whether access allowed. One generic {@link UrlAuthorizationRule} is provided which
29 * determines whether a given user can perform a specific operation for a specific resource
30 * type at a specific URL is allowed.
32 * The authorization service needs to access the current user through the
33 * {@link org.wamblee.security.authentication.UserAccessor} and needs access to the
34 * {@link org.wamblee.security.authentication.UserAdministration} to check whether the
35 * user belongs to certain groups.
