All Implemented Interfaces:

AuthenticationSuccessHandler

public class SavedRequestAwareAuthenticationSuccessHandler
extends SimpleUrlAuthenticationSuccessHandler

An authentication success strategy which can make use of the DefaultSavedRequest which may have been stored in the session by the ExceptionTranslationFilter. When such a request is intercepted and requires authentication, the request data is stored to record the original destination before the authentication process commenced, and to allow the request to be reconstructed when a redirect to the same URL occurs. This class is responsible for performing the redirect to the original URL if appropriate.

Following a successful authentication, it decides on the redirect destination, based on the following scenarios:

• If the alwaysUseDefaultTargetUrl property is set to true, the defaultTargetUrl will be used for the destination. Any DefaultSavedRequest stored in the session will be removed.
• If the targetUrlParameter has been set on the request, the value will be used as the destination. Any DefaultSavedRequest will again be removed.
• If a SavedRequest is found in the RequestCache (as set by the ExceptionTranslationFilter to record the original destination before the authentication process commenced), a redirect will be performed to the Url of that original destination. The SavedRequest object will remain cached and be picked up when the redirected request is received (See SavedRequestAwareWrapper).
• If no SavedRequest is found, it will delegate to the base class.
