authenticate
public Authentication authenticate(Authentication authentication) throws AuthenticationException
Description copied from interface:AuthenticationProvider
Performs authentication with the same contract asAuthenticationManager.authenticate(Authentication)
.- Specified by:
authenticate
in interfaceAuthenticationProvider
- Parameters:
authentication
- the authentication request object.- Returns:
- a fully authenticated object including credentials. May return
null
if theAuthenticationProvider
is unable to support authentication of the passedAuthentication
object. In such a case, the nextAuthenticationProvider
that supports the presentedAuthentication
class will be tried. - Throws:
AuthenticationException
- if authentication fails.

getKey
public java.lang.String getKey()

setMessageSource
public void setMessageSource(org.springframework.context.MessageSource messageSource)

supports
public boolean supports(java.lang.Class<?> authentication)
Description copied from interface:AuthenticationProvider
Returnstrue
if thisAuthenticationProvider
supports the indicatedAuthentication
object.Returning
true
does not guarantee anAuthenticationProvider
will be able to authenticate the presented instance of theAuthentication
class. It simply indicates it can support closer evaluation of it. AnAuthenticationProvider
can still returnnull
from theAuthenticationProvider.authenticate(Authentication)
method to indicate anotherAuthenticationProvider
should be tried.Selection of an
AuthenticationProvider
capable of performing authentication is conducted at runtime theProviderManager
.- Specified by:
supports
in interfaceAuthenticationProvider
- Returns:
true
if the implementation can more closely evaluate theAuthentication
class presented
