Class DelegatingAuthenticationEntryPoint

java.lang.Object

org.springframework.security.web.authentication.DelegatingAuthenticationEntryPoint

All Implemented Interfaces:

AuthenticationEntryPoint

public class DelegatingAuthenticationEntryPoint
extends java.lang.Object
implements AuthenticationEntryPoint

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.
