我就是我 2022-04-15 04:12 959阅读 0赞

# 环境要求 #

*  JDK 8+
 *  CAS 5.2
 *  tomcat 8+

# 步骤 #

## 一、搭建CAS服务器  --> [CAS（一）搭建CAS - server服务器][CAS_CAS - server] ##

## 二、配置hosts，加入如下配置 ##

127.0.0.1      cas.server.com
    127.0.0.1      cas.client1.com

## 三、搭建Springboot项目 ##

项目名为cas-clientB，项目结构如下：

*  包含三个页面：主页--index.jsp（无需登录），hello页面--hello.jsp（需要登录），退出成功提示页--logoutsuccess.jsp（无需登录）

*  pom.xml文件配置如下

                </plugin>
            </plugins>
        </build>
    </project>

*  application.properties配置：

cas.server-url-prefix=http://cas.server.com:8443/cas
    cas.server-login-url=http://cas.server.com:8443/cas/login
    cas.client-host-url=http://cas.client1.com:9002
    cas.use-session=true
    cas.validation-type=cas
    server.port=9002
    #自定义的退出url，退出成功后跳转到 http://cas.client1.com:9002/logout/success
    casClientLogoutUrl=http://cas.server.com:8443/cas/logout?service=http://cas.client1.com:9002/logout/success

其中[http://cas.server.com:8443][http_cas.server.com_8443]是服务端的地址，[http://cas.client1.com:9002][http_cas.client1.com_9002]是客户端地址

*  CASAutoConfig配置类，配置需要忽略授权的url：

@Configuration
    public class CASAutoConfig {
        @Value("${cas.server-url-prefix}")
        private String serverUrlPrefix;
        @Value("${cas.server-login-url}")
        private String serverLoginUrl;
        @Value("${cas.client-host-url}")
        private String clientHostUrl;
    
        /**
         * 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<String, String>();
            initParameters.put("casServerLoginUrl",serverLoginUrl);
            initParameters.put("serverName", clientHostUrl);
            //忽略的url，"|"分隔多个url
            initParameters.put("ignorePattern", "/logout/success|/index");
            registration.setInitParameters(initParameters);
            // 设定加载的顺序
            registration.setOrder(1);
            return registration;
        }
    }

*  CASController.java有两个业务如下：

@Controller
    public class CASController {
    
        @RequestMapping("index")
        public String index(ModelMap map) {
            map.addAttribute("name", "clien B");
            return "index";
        }
    
        @RequestMapping("hello")
        public String hello() {
            return "hello";
        }
    }

*  启动类加入开启cas client的注解

>     @EnableCasClient//启用cas client

## 四、启动项目、测试 ##

依次启动CAS-server服务端、CAS-clientB客户端

访问[http://cas.client1.com:9002/index][http_cas.client1.com_9002_index]进入CAS-clientB主页：

![20181121151515785.png][]

点击client B（[http://cas.client1.com:9002/hello][http_cas.client1.com_9002_hello]），会跳转到cas登录认证页面：

输入账号和密码完成登录后跳转到hello页面：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L291bXV2_size_16_color_FFFFFF_t_70 2][]
