无状态 CAS - 提供的代理回调 url j_spring_cas_security_proxyreceptor' 无法通过身份验证

Stateless CAS - The supplied proxy callback url j_spring_cas_security_proxyreceptor' could not be authenticated

我需要使用 CAS 保护我的 RESTful 无状态网络服务,现在我正在尝试按照此 Spring Stateless CAS 演示进行操作,但不断收到以下错误:

22:42:27.885 [http-nio-8443-exec-8] [first-spring-stateless] DEBUG o.s.s.c.web.CasAuthenticationFilter - Authentication request failed: org.springframework.security.authentication.BadCredentialsException: 
            The supplied proxy callback url 'https://localhost:8443/first-spring-stateless/j_spring_cas_security_proxyreceptor' could not be authenticated.

访问时 https://localhost:8443/first-spring-cas/testProxy.do url

例如我的 appointmentServiceUrl - https://localhost:8443/first-spring-stateless/appointment.jsp?ticket=PT-110-a2a6eOE3lwImcwGpZ2Jp-cas.example.com

这可能是什么原因?

通过添加

解决
<property name="proxyReceptorUrl"               value="/j_spring_cas_security_proxyreceptor"/>

casFilter

这是 casFilterapplicationContext-security.xml:

 <bean id="casFilter"
        class="org.springframework.security.cas.web.CasAuthenticationFilter">
    <property name="authenticationManager"          ref="authenticationManager"/>
    <property name="proxyGrantingTicketStorage"     ref="pgtStorage"/>
    <property name="serviceProperties"              ref="serviceProperties"/>

    <property name="proxyReceptorUrl"               value="/j_spring_cas_security_proxyreceptor"/>
    <property name="authenticationDetailsSource">
      <bean class="org.springframework.security.cas.web.authentication.ServiceAuthenticationDetailsSource"/>
    </property>
  </bean>
