Class BasicAuthenticationEntryPoint

java.lang.Object
  org.springframework.security.web.authentication.www.BasicAuthenticationEntryPoint

All Implemented Interfaces:

InitializingBean, AuthenticationEntryPoint

public class BasicAuthenticationEntryPoint
extends Object
implements AuthenticationEntryPoint, InitializingBean

Used by the ExceptionTraslationFilter to commence authentication via the BasicAuthenticationFilter.

Once a user agent is authenticated using BASIC authentication, logout requires that the browser be closed or an unauthorized (401) header be sent. The simplest way of achieving the latter is to call the commence(HttpServletRequest, HttpServletResponse, AuthenticationException) method below. This will indicate to the browser its credentials are no longer authorized, causing it to prompt the user to login again.
