org.acegisecurity.runas
Class RunAsImplAuthenticationProvider  

java.lang.Object
  org.acegisecurity.runas.RunAsImplAuthenticationProvider

All Implemented Interfaces:

org.acegisecurity.providers.AuthenticationProvider, org.springframework.beans.factory.InitializingBean, org.springframework.context.MessageSourceAware

---

public class RunAsImplAuthenticationProvider

extends java.lang.Object

implements org.springframework.beans.factory.InitializingBean, org.acegisecurity.providers.AuthenticationProvider, org.springframework.context.MessageSourceAware

An org.acegisecurity.providers.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.

Method Detail

afterPropertiesSet

public void afterPropertiesSet()
                        throws java.lang.Exception

Description copied from interface: org.springframework.beans.factory.InitializingBean

Invoked by a BeanFactory after it has set all bean properties supplied (and satisfied BeanFactoryAware and ApplicationContextAware).

This method allows the bean instance to perform initialization only possible when all bean properties have been set and to throw an exception in the event of misconfiguration.

Specified by:

afterPropertiesSet in interface org.springframework.beans.factory.InitializingBean

---

authenticate

public org.acegisecurity.Authentication authenticate(org.acegisecurity.Authentication authentication)
                                              throws org.acegisecurity.AuthenticationException

Description copied from interface: org.acegisecurity.providers.AuthenticationProvider

Performs authentication with the same contract as AuthenticationManager.authenticate(Authentication)>AuthenticationManager.authenticate(Authentication) 55 .

Specified by:

authenticate in interface org.acegisecurity.providers.AuthenticationProvider

---

getKey

public java.lang.String getKey()

---

setKey

public void setKey(java.lang.String key)

---

setMessageSource

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

Description copied from interface: org.springframework.context.MessageSourceAware

Set the MessageSource that this object runs in.

Invoked after population of normal bean properties but before an init callback like InitializingBean's afterPropertiesSet or a custom init-method. Invoked before ApplicationContextAware's setApplicationContext.

Specified by:

setMessageSource in interface org.springframework.context.MessageSourceAware

---

supports

public boolean supports(java.lang.Class authentication)

Description copied from interface: org.acegisecurity.providers.AuthenticationProvider

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 AuthenticationProvider.authenticate(Authentication)>AuthenticationProvider.authenticate(Authentication) 55 method to indicate another AuthenticationProvider should be tried.

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

Specified by:

supports in interface org.acegisecurity.providers.AuthenticationProvider
