Class RememberMeProcessingFilter

java.lang.Object
  org.acegisecurity.ui.rememberme.RememberMeProcessingFilter

All Implemented Interfaces:

javax.servlet.Filter, InitializingBean, ApplicationEventPublisherAware

public class RememberMeProcessingFilter
extends Object
implements javax.servlet.Filter, InitializingBean, ApplicationEventPublisherAware

Detects if there is no Authentication object in the SecurityContext, and populates it with a remember-me authentication token if a RememberMeServices implementation so requests.

Concrete RememberMeServices implementations will have their RememberMeServices.autoLogin(HttpServletRequest, HttpServletResponse) method called by this filter. The Authentication or null returned by that method will be placed into the SecurityContext.

If authentication is successful, an InteractiveAuthenticationSuccessEvent will be published to the application context. No events will be published if authentication was unsuccessful, because this would generally be recorded via an AuthenticationManager-specific application event.

Do not use this class directly. Instead configure web.xml to use the FilterToBeanProxy.
