RunAsImplAuthenticationProvider

extends Object
implements InitializingBean MessageSourceAware AuthenticationProvider
java.lang.Object
   ↳ org.springframework.security.access.intercept.RunAsImplAuthenticationProvider

Class Overview

An AuthenticationProvider implementation that can authenticate a RunAsUserToken.

Configured in the bean context with a key that should match the key used by adapters to generate the RunAsUserToken. It treats as valid any RunAsUserToken instance presenting a hash code that matches the RunAsImplAuthenticationProvider-configured key.

If the key does not match, a BadCredentialsException is thrown.

public Authentication authenticate (Authentication authentication)

Performs authentication with the same contract as authenticate(Authentication).

Parameters
authentication the authentication request object.

Throws
AuthenticationException

public String getKey ()

public void setKey (String key)

public void setMessageSource (MessageSource messageSource)

public boolean supports (Class<?> authentication)

Returns true if this AuthenticationProvider supports the indicated Authentication object.

Returning true does not guarantee an AuthenticationProvider will be able to authenticate the presented instance of the Authentication class. It simply indicates it can support closer evaluation of it. An AuthenticationProvider can still return null from the authenticate(Authentication) method to indicate another AuthenticationProvider should be tried.

Selection of an AuthenticationProvider capable of performing authentication is conducted at runtime the ProviderManager.

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