Method Detail

autoLogin

public Authentication autoLogin(HttpServletRequest request,
                                HttpServletResponse response)

Description copied from interface: RememberMeServices

This method will be called whenever the SecurityContextHolder does not contain an Authentication object and Spring Security wishes to provide an implementation with an opportunity to authenticate the request using remember-me capabilities. Spring Security makes no attempt whatsoever to determine whether the browser has requested remember-me services or presented a valid cookie. Such determinations are left to the implementation. If a browser has presented an unauthorised cookie for whatever reason, it should be silently ignored and invalidated using the HttpServletResponse object.

The returned Authentication must be acceptable to AuthenticationManager or AuthenticationProvider defined by the web application. It is recommended RememberMeAuthenticationToken be used in most cases, as it has a corresponding authentication provider.

Specified by:

autoLogin in interface RememberMeServices

Parameters:

request - to look for a remember-me token within

response - to change, cancel or modify the remember-me token

Returns:

a valid authentication object, or null if the request should not be authenticated

loginFail

public void loginFail(HttpServletRequest request,
                      HttpServletResponse response)

Description copied from interface: RememberMeServices

Called whenever an interactive authentication attempt was made, but the credentials supplied by the user were missing or otherwise invalid. Implementations should invalidate any and all remember-me tokens indicated in the HttpServletRequest.

Specified by:

loginFail in interface RememberMeServices

Parameters:

request - that contained an invalid authentication request

response - to change, cancel or modify the remember-me token

loginSuccess

public void loginSuccess(HttpServletRequest request,
                         HttpServletResponse response,
                         Authentication successfulAuthentication)

Description copied from interface: RememberMeServices

Called whenever an interactive authentication attempt is successful. An implementation may automatically set a remember-me token in the HttpServletResponse, although this is not recommended. Instead, implementations should typically look for a request parameter that indicates the browser has presented an explicit request for authentication to be remembered, such as the presence of a HTTP POST parameter.

Specified by:

loginSuccess in interface RememberMeServices

Parameters:

request - that contained the valid authentication request

response - to change, cancel or modify the remember-me token

successfulAuthentication - representing the successfully authenticated principal
