Class SimpleUrlAuthenticationFailureHandler

  • All Implemented Interfaces:
    Direct Known Subclasses:

    public class SimpleUrlAuthenticationFailureHandler
    extends java.lang.Object
    implements AuthenticationFailureHandler
    AuthenticationFailureHandler which performs a redirect to the value of the defaultFailureUrl property when the onAuthenticationFailure method is called. If the property has not been set it will send a 401 response to the client, with the error message from the AuthenticationException which caused the failure.

    If the useForward property is set, a RequestDispatcher.forward call will be made to the destination instead of a redirect.

      • onAuthenticationFailure

        public void onAuthenticationFailure​(javax.servlet.http.HttpServletRequest request,
                                            javax.servlet.http.HttpServletResponse response,
                                            AuthenticationException exception)
        Performs the redirect or forward to the defaultFailureUrl if set, otherwise returns a 401 error code.

        If redirecting or forwarding, saveException will be called to cache the exception for use in the target view.

        Specified by:
        onAuthenticationFailure in interface AuthenticationFailureHandler
        request - the request during which the authentication attempt occurred.
        response - the response.
        exception - the exception which was thrown to reject the authentication request.
      • saveException

        protected final void saveException​(javax.servlet.http.HttpServletRequest request,
                                           AuthenticationException exception)
        Caches the AuthenticationException for use in view rendering.

        If forwardToDestination is set to true, request scope will be used, otherwise it will attempt to store the exception in the session. If there is no session and allowSessionCreation is true a session will be created. Otherwise the exception will not be stored.

      • setDefaultFailureUrl

        public void setDefaultFailureUrl​(java.lang.String defaultFailureUrl)
        The URL which will be used as the failure destination.
        defaultFailureUrl - the failure URL, for example "/loginFailed.jsp".
      • isUseForward

        protected boolean isUseForward()
      • setUseForward

        public void setUseForward​(boolean forwardToDestination)
        If set to true, performs a forward to the failure destination URL instead of a redirect. Defaults to false.
      • setRedirectStrategy

        public void setRedirectStrategy​(RedirectStrategy redirectStrategy)
        Allows overriding of the behaviour when redirecting to a target URL.
      • isAllowSessionCreation

        protected boolean isAllowSessionCreation()
