SpringSecurity本身已经做好了与CAS的集成工作，只需要我们做简单配置就可以了

步骤1 spring-cas.xml配置文件内容如下(完整版)

    default-lazy-init="true"> 
    <context:component-scan base-package="com.itec.core" /> 
<!--SSO --> 
    <http auto-config="false" entry-point-ref="casEntryPoint" servlet-api-provision="true">    
        <intercept-url pattern="/login.do" filters="none" />

        <intercept-url pattern="/admin/*.do*" access="ROLE_LOGIN" />   
        <!-- logout-success-url="/login.html" -->

        <custom-filter position="FORM_LOGIN_FILTER" ref="casFilter"/>    
        <custom-filter ref="singleLogoutFilter" before="CAS_FILTER" /> 
    </http>   
 
    <beans:bean id="casEntryPoint"  class="org.springframework.security.cas.web.CasAuthenticationEntryPoint">    
        <beans:property name="loginUrl" value="http://172.19.50.21:9083/HASLSSO/login"/>    
        <beans:property name="serviceProperties" ref="serviceProperties"/>    
    </beans:bean> 
    <beans:bean id="serviceProperties"  class="org.springframework.security.cas.ServiceProperties">    
        <beans:property name="service"  value="http://172.19.4.225:8080/HACMS/j_spring_cas_security_check"/>    
        <beans:property name="sendRenew" value="false"/>    
    </beans:bean> 
 
    <beans:bean id="casFilter"  class="org.springframework.security.cas.web.CasAuthenticationFilter">    
        <beans:property name="authenticationManager" ref="authenticationManager"/>    
    </beans:bean>    
        
    <authentication-manager alias="authenticationManager">    
        <authentication-provider ref="casAuthenticationProvider"/>   
    </authentication-manager>    
        
    <beans:bean id="casAuthenticationUserDetailsService" class="org.springframework.security.core.userdetails.UserDetailsByNameServiceWrapper">    
        <beans:property name="userDetailsService" >    
            <beans:ref bean="userDetailsManager" />    
        </beans:property>    
    </beans:bean>    
       
    <beans:bean id="casAuthenticationProvider"    
            class="org.springframework.security.cas.authentication.CasAuthenticationProvider">    
        <beans:property name="authenticationUserDetailsService" ref="casAuthenticationUserDetailsService"/>    
        <beans:property name="serviceProperties" ref="serviceProperties" />    
        <beans:property name="ticketValidator">    
            <beans:bean class="org.jasig.cas.client.validation.Cas20ServiceTicketValidator">    
                <beans:constructor-arg index="0" value="http://172.19.50.21:9083/HASLSSO" />    
            </beans:bean>    
        </beans:property>    
        <beans:property name="key" value="an_id_for_this_auth_provider_only"/>    
    </beans:bean>    
 
    <!-- 注销客户端 --> 
    <beans:bean id="singleLogoutFilter" class="org.jasig.cas.client.session.SingleSignOutFilter" /> 
 
    <!-- 注销服务器端 --> 
    <beans:bean id="requestSingleLogoutFilter" 
    class="org.springframework.security.web.authentication.logout.LogoutFilter"> 
    <beans:constructor-arg 
    value="http://172.19.50.21:9083/HASLSSO/logout" /> 
    <beans:constructor-arg> 
    <beans:bean 
    class="org.springframework.security.web.authentication.logout.SecurityContextLogoutHandler"/> 
    </beans:constructor-arg> 
    <beans:property name="filterProcessesUrl" value="/j_spring_cas_security_logout" /> 
    </beans:bean> 
 
</beans:beans>    

 

步骤2 之前的UserDetailsManager不需要改任何代码

 

@Service 
public class UserDetailsManager implements UserDetailsService { 

步骤3 web.xml需要修改一点东西，不加载Security的配置文件就行了

 

<context-param> 
        <param-name>contextConfigLocation</param-name> 
        <!-- 使用工程本身验证 --> 
        <param-value>/WEB-INF/spring-config.xml,/WEB-INF/spring-freemarker.xml,/WEB-INF/spring-jpa.xml,/WEB-INF/spring-security.xml</param-value> 
        <!-- 使用 SSO 验证 --> 
<!--        <param-value>/WEB-INF/spring-config.xml,/WEB-INF/spring-freemarker.xml,/WEB-INF/spring-jpa.xml,/WEB-INF/spring-cas.xml</param-value> --> 
    </context-param> 

大功告成~！
