cas-client-autoconfig-support

b'cas-client-autoconfig-support' 是一个用于帮助 CAS（Central Authentication Service）客户端自动配置的工具。CAS是一种单点登录的解决方案，允许用户使用一组凭据（如用户名和密码）登录到多个应用程序。这个工具可以简化CAS客户端的配置过程，使其能够自动检测和设置必要的配置参数。

cas-client-autoconfig-support 解析ticket 配置springboot

可以回答这个问题。cas-client-autoconfig-support是一个CAS客户端自动配置的库，它可以帮助Spring Boot应用程序解析CAS服务器返回的ticket。它提供了一些自动配置选项，可以简化CAS客户端的配置过程。

springboot 如何调用cas-client-autoconfig-support 解析ticket

可以使用Spring Security CAS扩展来实现。在pom.xml文件中添加以下依赖项：

<dependency>
    <groupId>org.springframework.security.extensions</groupId>
    <artifactId>spring-security-cas</artifactId>
    <version>1.0.7.RELEASE</version>
</dependency>

然后在application.properties文件中添加以下配置：

# CAS server URL
cas.server.url=https://cas.example.com/cas
# CAS server login URL
cas.server.login.url=https://cas.example.com/cas/login
# CAS server logout URL
cas.server.logout.url=https://cas.example.com/cas/logout
# CAS service URL
cas.service.url=http://localhost:8080/login/cas
# CAS service name
cas.service.name=MyApp
# CAS service login URL
cas.service.login.url=http://localhost:8080/login
# CAS service logout URL
cas.service.logout.url=http://localhost:8080/logout
# CAS service validate URL
cas.service.validate.url=https://cas.example.com/cas/serviceValidate
# CAS service ticket parameter name
cas.service.ticket.parameterName=ticket
# CAS service renew parameter name
cas.service.renew.parameterName=renew
# CAS service gateway parameter name
cas.service.gateway.parameterName=gateway
# CAS service artifact parameter name
cas.service.artifact.parameterName=artifact
# CAS service proxy callback URL
cas.service.proxy.callbackUrl=http://localhost:8080/proxyCallback
# CAS service proxy callback parameter name
cas.service.proxy.callbackParameterName=pgtIou
# CAS service proxy granting ticket parameter name
cas.service.proxy.grantingTicket.parameterName=pgtIou
# CAS service proxy granting ticket storage class
cas.service.proxy.grantingTicket.storageClass=org.jasig.cas.client.proxy.ProxyGrantingTicketStorageImpl
# CAS service proxy granting ticket storage file
cas.service.proxy.grantingTicket.storageFile=/tmp/cas-proxy-granting-tickets
# CAS service proxy granting ticket storage clean interval
cas.service.proxy.grantingTicket.storageCleanInterval=3600000
# CAS service proxy granting ticket storage clean up
cas.service.proxy.grantingTicket.storageCleanUp=true
# CAS service proxy granting ticket storage clean up interval
cas.service.proxy.grantingTicket.storageCleanUpInterval=3600000
# CAS service proxy granting ticket storage clean up max age
cas.service.proxy.grantingTicket.storageCleanUpMaxAge=7200000

然后在Spring Boot应用程序中添加以下配置类：

@Configuration
@EnableWebSecurity
@EnableCasSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    private CasAuthenticationEntryPoint casAuthenticationEntryPoint;

    @Autowired
    private CasAuthenticationProvider casAuthenticationProvider;

    @Autowired
    private SingleSignOutFilter singleSignOutFilter;

    @Autowired
    private CasAuthenticationFilter casAuthenticationFilter;

    @Autowired
    private CasProperties casProperties;

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            .authorizeRequests()
                .antMatchers("/login").permitAll()
                .anyRequest().authenticated()
                .and()
            .exceptionHandling()
                .authenticationEntryPoint(casAuthenticationEntryPoint)
                .and()
            .logout()
                .logoutUrl("/logout")
                .logoutSuccessUrl("/")
                .addLogoutHandler(new SingleSignOutHandler(casProperties.getServer().getLogoutUrl()))
                .and()
            .addFilterBefore(singleSignOutFilter, CasAuthenticationFilter.class)
            .addFilter(casAuthenticationFilter);
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.authenticationProvider(casAuthenticationProvider);
    }

    @Bean
    public ServiceProperties serviceProperties() {
        ServiceProperties serviceProperties = new ServiceProperties();
        serviceProperties.setService(casProperties.getService().getUrl());
        serviceProperties.setSendRenew(false);
        return serviceProperties;
    }

    @Bean
    public CasAuthenticationEntryPoint casAuthenticationEntryPoint() {
        CasAuthenticationEntryPoint casAuthenticationEntryPoint = new CasAuthenticationEntryPoint();
        casAuthenticationEntryPoint.setLoginUrl(casProperties.getServer().getLoginUrl());
        casAuthenticationEntryPoint.setServiceProperties(serviceProperties());
        return casAuthenticationEntryPoint;
    }

    @Bean
    public CasAuthenticationProvider casAuthenticationProvider() {
        CasAuthenticationProvider casAuthenticationProvider = new CasAuthenticationProvider();
        casAuthenticationProvider.setAuthenticationUserDetailsService(new UserDetailsServiceImpl());
        casAuthenticationProvider.setServiceProperties(serviceProperties());
        casAuthenticationProvider.setTicketValidator(new Cas30ServiceTicketValidator(casProperties.getServer().getUrl()));
        casAuthenticationProvider.setKey("casAuthenticationProviderKey");
        return casAuthenticationProvider;
    }

    @Bean
    public SingleSignOutFilter singleSignOutFilter() {
        SingleSignOutFilter singleSignOutFilter = new SingleSignOutFilter();
        singleSignOutFilter.setCasServerUrlPrefix(casProperties.getServer().getUrl());
        singleSignOutFilter.setIgnoreInitConfiguration(true);
        return singleSignOutFilter;
    }

    @Bean
    public CasAuthenticationFilter casAuthenticationFilter() {
        CasAuthenticationFilter casAuthenticationFilter = new CasAuthenticationFilter();
        casAuthenticationFilter.setAuthenticationManager(authenticationManager());
        casAuthenticationFilter.setFilterProcessesUrl("/login/cas");
        return casAuthenticationFilter;
    }

}

最后，在Spring Boot应用程序中添加以下服务类：

@Service
public class UserDetailsServiceImpl implements AuthenticationUserDetailsService<CasAssertionAuthenticationToken> {

    @Override
    public UserDetails loadUserDetails(CasAssertionAuthenticationToken token) throws UsernameNotFoundException {
        String username = token.getName();
        List<GrantedAuthority> authorities = AuthorityUtils.createAuthorityList("ROLE_USER");
        return new User(username, "", authorities);
    }

}

现在，您可以使用Spring Boot应用程序调用CAS客户端自动配置支持来解析票据。
