public abstract class AbstractAuthenticationProcessingFilter extends GenericFilterBean implements ApplicationEventPublisherAware, MessageSourceAware
This filter will intercept a request and attempt to perform authentication from that
request if the request matches the
setRequiresAuthenticationRequestMatcher(RequestMatcher)
.
Authentication is performed by the
attemptAuthentication
method, which must be implemented by subclasses.
Authentication
object will be
placed into the SecurityContext
for the current thread, which is
guaranteed to have already been created by an earlier filter.
The configured AuthenticationSuccessHandler
will then be called to take the redirect to the
appropriate destination after a successful login. The default behaviour is implemented
in a SavedRequestAwareAuthenticationSuccessHandler
which will make use of any
DefaultSavedRequest set by the ExceptionTranslationFilter and
redirect the user to the URL contained therein. Otherwise it will redirect to the
webapp root "/". You can customize this behaviour by injecting a differently configured
instance of this class, or by using a different implementation.
See the
successfulAuthentication(HttpServletRequest, HttpServletResponse, FilterChain, Authentication)
method for more information.
AuthenticationFailureHandler
to allow the failure information to be conveyed to
the client. The default implementation is SimpleUrlAuthenticationFailureHandler
, which sends a 401 error code to the client. It may also be configured with a failure
URL as an alternative. Again you can inject whatever behaviour you require here.
InteractiveAuthenticationSuccessEvent
will
be published via the application context. No events will be published if authentication
was unsuccessful, because this would generally be recorded via an
AuthenticationManager
-specific application event.
SessionAuthenticationStrategy
which will be invoked
immediately after a successful call to attemptAuthentication()
. Different
implementations
can be
injected
to enable things like session-fixation attack prevention or to control the
number of simultaneous sessions a principal may have.Modifier and Type | Field and Description |
