Examples of org.springframework.security.core.Authentication

org.springframework.security.core.Authentication
Represents the token for an authentication request or for an authenticated principal once the request has been processed by the {@link AuthenticationManager#authenticate(Authentication)} method.
Once the request has been authenticated, the Authentication will usually be stored in a thread-local SecurityContext managed by the {@link SecurityContextHolder} by the authentication mechanism which isbeing used. An explicit authentication can be achieved, without using one of Spring Security's authentication mechanisms, by creating an Authentication instance and using the code:
```
 SecurityContextHolder.getContext().setAuthentication(anAuthentication); 
```
Note that unless the Authentication has the authenticated property set to true, it will still be authenticated by any security interceptor (for method or web invocations) which encounters it.
In most cases, the framework transparently takes care of managing the security context and authentication objects for you. @author Ben Alex
