| /** |
| * The Shiro framework's default concrete implementation of the {@link SecurityManager} interface, |
| * based around a collection of {@link org.apache.shiro.realm.Realm}s. This implementation delegates its |
| * authentication, authorization, and session operations to wrapped {@link Authenticator}, {@link Authorizer}, and |
| * {@link org.apache.shiro.session.mgt.SessionManager SessionManager} instances respectively via superclass |
| * implementation. |
| * <p/> |
| * To greatly reduce and simplify configuration, this implementation (and its superclasses) will |
| * create suitable defaults for all of its required dependencies, <em>except</em> the required one or more |
| * {@link Realm Realm}s. Because {@code Realm} implementations usually interact with an application's data model, |
| * they are almost always application specific; you will want to specify at least one custom |
| * {@code Realm} implementation that 'knows' about your application's data/security model |
| * (via {@link #setRealm} or one of the overloaded constructors). All other attributes in this class hierarchy |
| * will have suitable defaults for most enterprise applications. |
| * <p/> |
| * <b>RememberMe notice</b>: This class supports the ability to configure a |
| * {@link #setRememberMeManager RememberMeManager} |
| * for {@code RememberMe} identity services for login/logout, BUT, a default instance <em>will not</em> be created |
| * for this attribute at startup. |
| * <p/> |
| * Because RememberMe services are inherently client tier-specific and |
| * therefore aplication-dependent, if you want {@code RememberMe} services enabled, you will have to specify an |
| * instance yourself via the {@link #setRememberMeManager(RememberMeManager) setRememberMeManager} |
| * mutator. However if you're reading this JavaDoc with the |
| * expectation of operating in a Web environment, take a look at the |
| * {@code org.apache.shiro.web.DefaultWebSecurityManager} implementation, which |
| * <em>does</em> support {@code RememberMe} services by default at startup. |
