spring boot-整合CAS Client实现单点登陆验证

依赖：

<dependency>
<groupId>net.unicon.cas</groupId>
<artifactId>cas-client-autoconfig-support</artifactId>
<version>1.4.0-GA</version>
</dependency>

增加配置文件：

cas.server-url-prefix=http://127.0.0.1            地址前缀
cas.server-login-url=http://127.0.0.1/login   认证地址
cas.client-host-url=http://192.26.4.28:8080   认证成功跳转地址
cas.validation-type=CAS    

-----cas.validation-type目前支持3中方式：1、CAS；2、CAS3；3、SAML

开启CAS Client支持

@SpringBootApplication

@ComponentScan(basePackages={"com.chhliu.emailservice"})
@EnableCasClient // 开启CAS支持
public class Application extends SpringBootServletInitializer{
 public static void main(String[] args) {
 SpringApplication.run(Application.class, args);
   
 }
}

 

测试方法：

@Controller
public class TestController {

    @Value(value = "${cas.server-url-prefix}")
    private String serverUrlPrefix = "";

    @Value(value = "${cas.client-host-url}")
    private String clientHostUrl = "";

    @GetMapping("user")
    @ResponseBody
    public String user(HttpServletRequest request) {
        Assertion assertion = (Assertion) request.getSession().getAttribute(AbstractCasFilter.CONST_CAS_ASSERTION);
        String loginName = null;
        if (assertion != null) {
            AttributePrincipal principal = assertion.getPrincipal();
            loginName = principal.getName();
            System.out.println("访问者:" + loginName);
        }
        return "访问者:" + loginName;
    }

    @RequestMapping("/logout")
    public String logout(HttpSession session) {
        session.invalidate();
        return "redirect:" + serverUrlPrefix + "/logout?service=" + clientHostUrl + "/sso-client/user";
    }
}

5.1 登录：

（1）打开浏览器访问：http://127.0.0.1:8888/sso-client/user
（2）由于没有登录，重定向到：http://146.56.192.87:8080/cas/login?service=http://127.0.0.1:8888/sso-client/user
（3）输入用户名密码，点击登录，成功之后跳转到http://127.0.0.1:8888/sso-client/user中

5.2 退出：

（4）访问：http://127.0.0.1:8888/sso-client/logout
（5）cas完成退出，并跳转到http://127.0.0.1:8888/sso-client/user，由于该地址需要登录，仍会重定向到登录界面
