SSL(https)修改：

• 之前的Https是用Nginx加Lets Encrypt生成的免费证书来做的，这样子就配置的nginx代理；

• 之前的项目是配置在tomcat中的，访问的时候是通过nginx代理来访问到tomcat中；

• 这边的cas认证说不可以通过代理，所以要把nginx去掉，就从新申请了一个腾讯云的免费ssl证书：

• 申请流程（过程中选择文件验证）：https://www.soweng.com/ssl/39.html

• 配置流程（选择tomca8.5.35t证书部署）：https://www.jianshu.com/p/7a8e7b9e04d2

 <Connector port="80" protocol="HTTP/1.1"
               connectionTimeout="20000"

基于Springboot的cas配置

• 给的文档中仅有基于web.xml的cas配置，项目这边是基于springboot来做的，就需要把配置在springboot里面来实现；

• 用了一个cas自动配置的工具：cas-client-autoconfig-support

• 文档中给的是cas-client-core3.2.1，客服说是标准的cas方式 来弄的，就直接到了一个3.5.0的配合cas-client-autoconfig-support2.2.0-GA来做：

pom.xml配置：

 <!--cas的客户端 -->
        <dependency>
            <groupId>net.unicon.cas</groupId>
            <artifactId>cas-client-autoconfig-support</artifactId>
            <version>2.2.0-GA</version>
            <exclusions>
                <exclusion>
                    <groupId>org.jasig.cas.client</groupId>
                    <artifactId>cas-client-core</artifactId>
                </exclusion>
            </exclusions>
        </dependency>

        <dependency>
            <groupId>org.jasig.cas.client</groupId>
            <artifactId>cas-client-core</artifactId>
            <version>3.5.0</version>
        </dependency>

yml文件配置

#cas 前缀
cas:
  server-url-prefix: https://***.cn/authserver
  #cas cas登录
  server-login-url: https://***.cn/authserver/login
  #回调
  client-host-url: https://***.cn/**/cas/login

  #Ticket校验器使用Cas30ProxyReceivingTicketValidationFilter
  validation-type: CAS3
  #cas不拦截的url
udf:
  ignore-host-url: /|/*|/**/cas/login|/cas/login
  ignore-url-pattern-type: ""

设置ignore-host-url

@Configuration
public class CASConfig {

    @Value("${cas.server-url-prefix}")
    private String serverUrlPrefix;
    @Value("${cas.server-login-url}")
    private String serverLoginUrl;
    @Value("${cas.client-host-url}")
    private String clientHostUrl;
    @Value("${udf.ignore-host-url}")
    private String ignoreHostUrl;
    @Value("${udf.ignore-url-pattern-type}")
    private String ignoreUrlPatternType;


    /**
     * 授权过滤器
     * @return
     */
    @Bean
    public FilterRegistrationBean filterAuthenticationRegistration() {
        FilterRegistrationBean registration = new FilterRegistrationBean();
        registration.setFilter(new AuthenticationFilter());
        // 设定匹配的路径
        registration.addUrlPatterns("/*");
        Map<String, String> initParameters = new HashMap<>();
        initParameters.put("casServerLoginUrl", serverLoginUrl);
        initParameters.put("serverName", clientHostUrl);
        //忽略的url，"|"分隔多个url
        if(StrUtil.isNotEmpty(ignoreHostUrl)) {
            for(int i= 0 ;i<100;i++){
                System.out.println("ignoreHostUrl"+ignoreHostUrl);
            }
            initParameters.put("ignorePattern", ignoreHostUrl);
        }
        registration.setInitParameters(initParameters);
        // 设定加载的顺序
        registration.setOrder(1);
        return registration;

    }

}

设置cas登出

/**
     * 退出登录
     */
    @RequestMapping(value = "/logout", method = RequestMethod.GET)
    public String logOut() {
        LogManager.me().executeLog(LogTaskFactory.exitLog(ShiroKit.getUser().getId(), getIp()));
        ShiroKit.getSubject().logout();
        deleteAllCookie();

        String casLogoutURL = "https://*****.cn/authserver/logout";
        String redirectURL = casLogoutURL + "?service=https%3A%2F%2F*****.cn%2F***%2Fcas%2Flogin";

        //return REDIRECT + "/login";
        return REDIRECT + redirectURL;
    }

设置过滤问题

shiroFilter中添加：
hashMap.put("/cas/**", "anon");
