org.springframework.security.web.authentication.preauth
Class PreAuthenticatedAuthenticationProvider

java.lang.Object
  org.springframework.security.web.authentication.preauth.PreAuthenticatedAuthenticationProvider

All Implemented Interfaces:

org.springframework.beans.factory.InitializingBean, org.springframework.core.Ordered, AuthenticationProvider

public class PreAuthenticatedAuthenticationProvider
extends java.lang.Object
implements AuthenticationProvider, org.springframework.beans.factory.InitializingBean, org.springframework.core.Ordered

Processes a pre-authenticated authentication request. The request will typically originate from a AbstractPreAuthenticatedProcessingFilter subclass.

This authentication provider will not perform any checks on authentication requests, as they should already be pre-authenticated. However, the AuthenticationUserDetailsService implementation may still throw a UsernameNotFoundException, for example.

Since:

2.0

authenticate

public Authentication authenticate(Authentication authentication)
                            throws AuthenticationException

Authenticate the given PreAuthenticatedAuthenticationToken.

If the principal contained in the authentication object is null, the request will be ignored to allow other providers to authenticate it.

Parameters:

authentication - the authentication request object.

Returns:

a fully authenticated object including credentials. May return null if the AuthenticationProvider is unable to support authentication of the passed Authentication object. In such a case, the next AuthenticationProvider that supports the presented Authentication class will be tried.

Throws:

AuthenticationException - if authentication fails.

supports

public boolean supports(java.lang.Class<? extends java.lang.Object> authentication)

Indicate that this provider only supports PreAuthenticatedAuthenticationToken (sub)classes.

Specified by:

supports in interface AuthenticationProvider

Parameters:

authentication - DOCUMENT ME!

Returns:

true if the implementation can more closely evaluate the Authentication class presented

setPreAuthenticatedUserDetailsService

public void setPreAuthenticatedUserDetailsService(AuthenticationUserDetailsService aPreAuthenticatedUserDetailsService)

Set the AuthenticatedUserDetailsServices to be used.

Parameters:

aPreAuthenticatedUserDetailsService -

getOrder

public int getOrder()

Specified by:

getOrder in interface org.springframework.core.Ordered

setOrder

public void setOrder(int i)

setThrowExceptionWhenTokenRejected

public void setThrowExceptionWhenTokenRejected(boolean throwExceptionWhenTokenRejected)

If true, causes the provider to throw a BadCredentialsException if the presented authentication request is invalid (contains a null principal or credentials). Otherwise it will just return null. Defaults to false.
