我正在尝试将 PreAuthFilter（用于 Siteminder）与 Spring Security 3.0 一起使用。

 <http  use-expressions="true">
        <intercept-url pattern="/admin/**" access="hasRole('ROLE_ADMIN')" />
        <intercept-url pattern="/403.jsp" access="permitAll" />
        <!-- Allow non-secure access to static resources  -->
        <intercept-url pattern="/css/**" filters="none" />
        <intercept-url pattern="/images/**" filters="none" />

        <custom-filter ref="siteminderFilter" position="PRE_AUTH_FILTER"/>

<!--        <form-login  /> -->
        <logout logout-success-url="/index.jsp"/>
    </http>

    <beans:bean id="siteminderFilter" class="org.springframework.security.web.authentication.preauth.RequestHeaderAuthenticationFilter">
        <beans:property name="principalRequestHeader" value="SM_USER"/>
        <beans:property name="authenticationManager" ref="authenticationManager" />
        <beans:property name="exceptionIfHeaderMissing" value="false"/>
    </beans:bean>

    <beans:bean id="AdminUserDetailsService" class="com.fw.security.auth.MyUserDetailsService">
    </beans:bean>

    <beans:bean id="preauthAuthProvider" class="org.springframework.security.web.authentication.preauth.PreAuthenticatedAuthenticationProvider">
        <beans:property name="preAuthenticatedUserDetailsService">
            <beans:bean id="userDetailsServiceWrapper" class="org.springframework.security.core.userdetails.UserDetailsByNameServiceWrapper">
                <beans:property name="userDetailsService" ref="AdminUserDetailsService"/>
            </beans:bean>
        </beans:property>
    </beans:bean>

    <authentication-manager alias="authenticationManager">
      <authentication-provider ref="preauthAuthProvider" />
    </authentication-manager>

上面的配置失败了

org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: No AuthenticationEntryPoint could be established. Please make sure you have a login mechanism configured through the namespace (such as form-login) or specify a custom AuthenticationEntryPoint with the 'entry-point-ref' attribute 
Offending resource: ServletContext resource [/WEB-INF/security-app-context.xml]

1）我如何指定一个AuthenticationEntryPoint？？？

2) 它真的适用于 PreAuthentication 场景吗？？？

解决方案

根据以下axtavt的解决方案：

使用 Http403ForbiddenEntryPoint 创建一个 bean

<beans:bean id="http403EntryPoint" class="org.springframework.security.web.authentication.Http403ForbiddenEntryPoint">
    </beans:bean>

并在 <http> 中引用它

<http  use-expressions="true" auto-config="false" entry-point-ref="http403EntryPoint">

我猜在预认证的情况下，您需要声明一个Http403ForbiddenEntryPoint并entry-point-ref通过<http>.
