cas+spring安全性

Question

我正在尝试在我的应用程序中实现单点登录，目前，我面临着下一个问题：

HTTP Status 401 - Authentication Failed: Failed to provide a CAS service ticket to validate

type Status report

message Authentication Failed: Failed to provide a CAS service ticket to validate

description This request requires HTTP authentication (Authentication Failed: Failed to provide a CAS service ticket to validate).

我在不同的tomcat上启动我的cas服务器，在那里登录，当我转到我的应用程序的登录页面时，然后: 1. then is no autologin 2.当我输入凭据时，我看到上面显示的堆栈跟踪我从this site获取了一个示例。

下面是我的spring安全上下文：

<security:global-method-security  pre-post-annotations="enabled" />

    <security:http use-expressions="true" auto-config="true"
        entry-point-ref="casAuthenticationEntryPoint" >

    <security:custom-filter position="CAS_FILTER" ref="casAuthenticationFilter"></security:custom-filter>

        <security:access-denied-handler  ref="accessDeniedHandler" />

        <security:form-login login-page="/login.html"
            authentication-failure-url="/login.html?login_error=1"
            default-target-url="/index.html" 
            always-use-default-target="false"
            login-processing-url="/j_spring_security_check"
            authentication-failure-handler-ref="failureHandler"
            authentication-success-handler-ref="successHandler" />
        <security:logout logout-url="/logout" logout-success-url="/login.html" />

        <security:intercept-url pattern="/member/**" access="hasRole('viewer')" />
        <security:intercept-url pattern="/admin/**" access="hasRole('SiteAdmin')" />
        <security:intercept-url pattern="/admin/**" access="hasRole('SystemAdmin')" />

        <security:remember-me />
    </security:http>

    <security:authentication-manager alias="authenticationManager">
        <security:authentication-provider user-service-ref="myUserDetailsService" />
        <security:authentication-provider ref="casAuthenticationProvider"></security:authentication-provider>
    </security:authentication-manager>

    <bean id="myUserDetailsService"
        class="com.mypackage.MyUserDetailsService">
    </bean>

    <bean id="authenticationEntryPoint"
        class="org.springframework.security.web.authentication.LoginUrlAuthenticationEntryPoint">

    </bean>

                <constructor-arg index="0" value="http://localhost:9080/cas-server-webapp-3.4.10"></constructor-arg>
            </bean>
        </property>
        <property name="key" value="cas"></property>
    </bean>

在web.xml中，我已经包含了spring安全上下文，并设置了适当的侦听器等。在pom(我使用maven)中，我已经添加了所需的依赖项，如本文所述。但问题依然存在。我很高兴有任何建议

Answer 1

从您的错误消息“此请求需要HTTP身份验证”可以看出，您的CAS服务器启用了身份验证。您需要停用它并通过HTML页面登录(即它将是JSP、ASP或类似的东西)。

Answer 2

我得到了相同的跟踪，当

<servlet-mapping>
    <servlet-name>springmvc</servlet-name>
    <url-pattern>*.do</url-pattern>
</servlet-mapping>

但是cas登录url没有*.do suffix.When，我加上了.do，它工作得很好。
