Java Can'；t使用Spring Security使CAS单点注销正常工作

我没有找到在我的应用程序上实现单一注销CAS功能的实际指南。我在这里尝试了很多答案，但没有一个有效（像和）。此外，还没有找到使用Java配置的SpringSecurity+CAS的例子，所以我对这一点也有点迷茫。我甚至无法确定这是否是我应该使用的实际URL，因为文档告诉我使用“/j_spring_security_logout”，这只是将我重定向到一个空白的索引页，因为如果我正常访问它，我的索引页会正常工作（尽管控制台显示了所有正确的请求，如JS和CSS）。如果您能提供一些指导，我将不胜感激，因为我找不到使用Java注释的文档。提前谢谢

我的网站安全配置：

@Configuration

@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    private static String CAS_URL = "https://localhost:8443/cas";
    private static String APP_URL = "https://localhost:8443/i9t-YM";

    @Bean
    public ServiceProperties serviceProperties() {
        ServiceProperties serviceProperties = new ServiceProperties();
        serviceProperties.setService(APP_URL+"/j_spring_cas_security_check");
        serviceProperties.setSendRenew(false);
        return serviceProperties;
    }

    @Bean
    public CasAuthenticationProvider casAuthenticationProvider() {
        CasAuthenticationProvider casAuthenticationProvider = new CasAuthenticationProvider();
        casAuthenticationProvider.setAuthenticationUserDetailsService(authenticationUserDetailsService());
        casAuthenticationProvider.setServiceProperties(serviceProperties());
        casAuthenticationProvider.setTicketValidator(cas20ServiceTicketValidator());
        casAuthenticationProvider.setKey("an_id_for_this_auth_provider_only");
        return casAuthenticationProvider;
    }

    @Bean
    public AuthenticationUserDetailsService authenticationUserDetailsService() {
        return new TestCasAuthenticationUserDetailsService();
    }

    @Bean
    public Cas20ServiceTicketValidator cas20ServiceTicketValidator() {
        return new Cas20ServiceTicketValidator(CAS_URL);
    }

    @Bean
    public CasAuthenticationFilter casAuthenticationFilter() throws Exception {
        CasAuthenticationFilter casAuthenticationFilter = new CasAuthenticationFilter();
        casAuthenticationFilter.setAuthenticationManager(authenticationManager());
        return casAuthenticationFilter;
    }

    @Bean
    public CasAuthenticationEntryPoint casAuthenticationEntryPoint() {
        CasAuthenticationEntryPoint casAuthenticationEntryPoint = new CasAuthenticationEntryPoint();
        casAuthenticationEntryPoint.setLoginUrl(CAS_URL+"/login");
        casAuthenticationEntryPoint.setServiceProperties(serviceProperties());
        return casAuthenticationEntryPoint;
    }

    @Bean
    public SingleSignOutFilter SingleSignOutFilter(){
        return new SingleSignOutFilter();
    }

    @Bean
    public LogoutFilter requestLogoutFilter(){
        SecurityContextLogoutHandler handler = new SecurityContextLogoutHandler();
        handler.setClearAuthentication(true);
        handler.setInvalidateHttpSession(true);
        LogoutFilter logoutFilter = new LogoutFilter(APP_URL, handler);
        return logoutFilter;
    }

    @Override
    public void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.authenticationProvider(casAuthenticationProvider());
        auth.inMemoryAuthentication().withUser("joe").password("joe").roles("USER");
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.addFilter(casAuthenticationFilter());
        http.exceptionHandling().authenticationEntryPoint(casAuthenticationEntryPoint());
        http.addFilterBefore(requestLogoutFilter(), LogoutFilter.class);
        http.addFilterBefore(SingleSignOutFilter(), CasAuthenticationFilter.class);
        http.httpBasic().and().authorizeRequests().antMatchers("/index.html", "/home.html", "/login.html", "/")
                .permitAll().anyRequest().authenticated()
        .and().addFilterAfter(new CsrfHeaderFilter(), CsrfFilter.class)
                .csrf().csrfTokenRepository(csrfTokenRepository())
                ;
        http.logout()
        .deleteCookies("remove").invalidateHttpSession(true).logoutUrl("cas/logout")
        .logoutSuccessUrl("/");
        //http.exceptionHandling().accessDeniedPage("/403.html");
    }

    private CsrfTokenRepository csrfTokenRepository() {
        HttpSessionCsrfTokenRepository repository = new HttpSessionCsrfTokenRepository();
        repository.setHeaderName("X-XSRF-TOKEN");
        return repository;
    }

}

我的Web.xml上的SSOut过滤器，不知道我添加它的确切原因：

<filter>
  <filter-name>characterEncodingFilter</filter-name>
  <filter-class>
    org.springframework.web.filter.CharacterEncodingFilter
  </filter-class>
  <init-param>
    <param-name>encoding</param-name>
    <param-value>UTF-8</param-value>
  </init-param>
</filter>
<filter-mapping>
  <filter-name>characterEncodingFilter</filter-name>
  <url-pattern>/*</url-pattern>
</filter-mapping>
<listener>
  <listener-class>
    org.jasig.cas.client.session.SingleSignOutHttpSessionListener
  </listener-class>
</listener>

字符编码滤波器
org.springframework.web.filter.CharacterEncodingFilter
编码
UTF-8
字符编码滤波器
/*
org.jasig.cas.client.session.SingleSignOutHttpSessionListener

这是我对使用cas集成的spring安全性进行单点注销的配置：

<bean id="singleLogoutFilter" class="org.jasig.cas.client.session.SingleSignOutFilter" />

<bean id="requestSingleLogoutFilter"
    class="org.springframework.security.web.authentication.logout.LogoutFilter">
    <constructor-arg
        value="${cas.server.address}/logout?service=${cas.server.address}" />
    <constructor-arg>
        <bean
            class="org.springframework.security.web.authentication.logout.SecurityContextLogoutHandler" />
    </constructor-arg>
    <property name="filterProcessesUrl" value="/j_spring_cas_security_logout" />
</bean>

为什么不编写一个控制器方法呢？在这个方法中，您可以手动注销用户并将用户重定向到任何您想要的地方。我会将用户身份验证设置为null。@WeareBorg但问题是：Spring security不应该为我这样做吗？据我从文档中了解，我只需要这样做，当Spring收到“/j_Spring_security_cas_logout”时，它将使会话无效，然后从cas的角度来看，SSOut将是可选的。除非我真的不明白。让我检查一下……因为我不再处理这个问题了，我无论如何都接受这个答案。但是，我现在没有办法再测试它了，对不起。不过还是要谢谢你@Yuri-M-Dias我在cas有多年的经验，这就是我在我们的项目中所做的，并且它是有效的

<sec:filter-chain pattern="/logout*" 
    filters="securityContextPersistenceFilter,singleLogoutFilter,casAuthenticationFilter" />
<sec:filter-chain pattern="/j_spring_cas_security_logout*"
    filters="requestSingleLogoutFilter" />
