+
+感谢 xiazhenyou 提供Demo。
+
+# cas-client-boot-demo
+基于spring boot配置cas客户端
+demo分别写了三个请求:拦截请求 test1/index,test1/index1 以及不拦截请求test1/index2,
+## 第一步，引入cas 客户端所需包
+      <dependency>
+            <groupId>net.unicon.cas</groupId>
+            <artifactId>cas-client-autoconfig-support</artifactId>
+            <version>2.3.0-GA</version>
+      </dependency>
+## 第二部，配置spring boot 配置文件
+```
+server:
+  port: 8989
+cas:
+  # cas服务端地址
+  server-url-prefix: http://sso.maxkey.top/sign/authz/cas/
+  # cas服务端登陆地址
+  server-login-url: http://sso.maxkey.top/sign/authz/cas/login
+  # 客户端访问地址
+  client-host-url: http://localhost:8989/
+  # 认证方式，默认cas
+  validation-type: cas
+  #  客户端需要拦截的URL地址
+  authentication-url-patterns:
+    - /test1/index
+    - /test1/index1
+```
+扩展配置项
+````
+cas.authentication-url-patterns
+cas.validation-url-patterns
+cas.request-wrapper-url-patterns
+cas.assertion-thread-local-url-patterns
+cas.gateway
+cas.use-session
+cas.redirect-after-validation
+cas.allowed-proxy-chains
+cas.proxy-callback-url
+cas.proxy-receptor-url
+cas.accept-any-proxy
+server.context-parameters.renew
+````
+## 第三部 在application启动类上加上 @EnableCasClient 注解
+```java
+@SpringBootApplication
+@EnableCasClient
+public class CasClientDemoApplication {
+
+    public static void main(String[] args) {
+        SpringApplication.run(DemoApplication.class, args);
+    }
+
+}
+```
+## 第四步 在代码中获取登录用户信息
+``` java
+    @GetMapping("test1/index1")
+    public String index1(HttpServletRequest request){
+        String token =request.getParameter("token");
+        System.out.println("token : "+token);
+        Assertion assertion = (Assertion) request.getSession().getAttribute(AbstractCasFilter.CONST_CAS_ASSERTION);
+
+        String username=     assertion.getPrincipal().getName();
+        System.out.println(username);
+
+        return "test index cas拦截正常,登录账号:"+username;
+    }
+```
