Package org.springframework.security.web.authentication

Class DelegatingAuthenticationEntryPoint

java.lang.Object

org.springframework.security.web.authentication.DelegatingAuthenticationEntryPoint

All Implemented Interfaces:

org.springframework.beans.factory.InitializingBean, AuthenticationEntryPoint

public class DelegatingAuthenticationEntryPoint
extends Object
implements AuthenticationEntryPoint, org.springframework.beans.factory.InitializingBean

An AuthenticationEntryPoint which selects a concrete AuthenticationEntryPoint based on a RequestMatcher evaluation.

A configuration might look like this:

 <bean id="daep" class="org.springframework.security.web.authentication.DelegatingAuthenticationEntryPoint">
     <constructor-arg>
         <map>
             <entry key="hasIpAddress('192.168.1.0/24') and hasHeader('User-Agent','Mozilla')" value-ref="firstAEP" />
             <entry key="hasHeader('User-Agent','MSIE')" value-ref="secondAEP" />
         </map>
     </constructor-arg>
     <property name="defaultEntryPoint" ref="defaultAEP"/>
 </bean>
 

This example uses the RequestMatcherEditor which creates a ELRequestMatcher instances for the map keys.

Since:

3.0.2

commence

public void commence(jakarta.servlet.http.HttpServletRequest request,
 jakarta.servlet.http.HttpServletResponse response,
 AuthenticationException authException)
              throws IOException,
jakarta.servlet.ServletException

Description copied from interface: AuthenticationEntryPoint

Commences an authentication scheme.

ExceptionTranslationFilter will populate the HttpSession attribute named AbstractAuthenticationProcessingFilter.SPRING_SECURITY_SAVED_REQUEST_KEY with the requested target URL before calling this method.

Implementations should modify the headers on the ServletResponse as necessary to commence the authentication process.

Specified by:

commence in interface AuthenticationEntryPoint

Parameters:

request - that resulted in an AuthenticationException

response - so that the user agent can begin authentication

authException - that caused the invocation

Throws:

IOException

jakarta.servlet.ServletException

public void setDefaultEntryPoint(AuthenticationEntryPoint defaultEntryPoint)

Deprecated, for removal: This API element is subject to removal in a future version.

Use DelegatingAuthenticationEntryPoint(AuthenticationEntryPoint, List)

EntryPoint which is used when no RequestMatcher returned true

afterPropertiesSet

public void afterPropertiesSet()

Specified by:

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

builder

public static DelegatingAuthenticationEntryPoint.Builder builder()

Creates a new DelegatingAuthenticationEntryPoint.Builder

Returns:

the new DelegatingAuthenticationEntryPoint.Builder
