使用带有CAS的Spring Security Filter，AuthenticationuserDetailserss

Question

我是Spring Security的新手，我在Web.xml文件中设置了一个委托FilterProxy Spring Security Filter。当没有限制页面或目录时，我正在尝试使用CAS身份验证设置弹簧安全过滤器。每个网页都有两个部分受保护的部分（Loggedin可以看到它）和未保护（匿名），并且页面顶部还有一个登录链接（到CAS Remote Server）。我越来越严重：错误的听力是由必须设置AuthenticationuserDetailsservice 错误

我正在使用Spring 3.0 MVC （Tomcat6 Apache2.2 JK_Module）Web应用程序，该应用程序在实施Spring Security CAS
之前正常工作谢谢，MK

Answer 1

错误消息几乎可以钉住它。您的CasAuthenticationProvider缺少对另一个BEAN的引用，该bean可以访问您应用程序的用户信息：

<bean id="casAuthProvider" class="org.springframework.security.cas.authentication.CasAuthenticationProvider">
    <property name="ticketValidator" ref="ticketValidator"/>
    <property name="serviceProperties" ref="serviceProperties"/>
    <!-- You are missing this -->
    <property name="authenticationUserDetailsService">
        <bean
            class="org.springframework.security.core.userdetails.UserDetailsByNameServiceWrapper">
            <constructor-arg ref="userService" />
        </bean>
    </property>
</bean>

其中userService是UserDetailsService实例。有关工作示例，请参见CAS样本申请。
