All Implemented Interfaces:

javax.servlet.Filter, org.springframework.beans.factory.Aware, org.springframework.beans.factory.BeanNameAware, org.springframework.beans.factory.DisposableBean, org.springframework.beans.factory.InitializingBean, org.springframework.context.EnvironmentAware, org.springframework.core.env.EnvironmentCapable, org.springframework.web.context.ServletContextAware

public class AuthenticationFilter
extends org.springframework.web.filter.OncePerRequestFilter

A Filter that performs authentication of a particular request. An outline of the logic:

• A request comes in and if it does not match setRequestMatcher(RequestMatcher), then this filter does nothing and the FilterChain is continued. If it does match then...
• An attempt to convert the HttpServletRequest into an Authentication is made. If the result is empty, then the filter does nothing more and the FilterChain is continued. If it does create an Authentication...
• The AuthenticationManager specified in AuthenticationFilter(AuthenticationManager, AuthenticationConverter) is used to perform authentication.
• The AuthenticationManagerResolver specified in AuthenticationFilter(AuthenticationManagerResolver, AuthenticationConverter) is used to resolve the appropriate authentication manager from context to perform authentication.
• If authentication is successful, AuthenticationSuccessHandler is invoked and the authentication is set on SecurityContextHolder, else AuthenticationFailureHandler is invoked

Since:

5.2.0
