CAS Server（二）：基于SpringBoot搭建客户端
1. 概述
本篇介紹SpringBoot項(xiàng)目接入CAS Server，先創(chuàng)建一個(gè)空的SpringBoot項(xiàng)目
2. pom.xml
<parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.3.5.RELEASE</version><relativePath/> <!-- lookup parent from repository --></parent><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-thymeleaf</artifactId></dependency><dependency><groupId>net.unicon.cas</groupId><artifactId>cas-client-autoconfig-support</artifactId><version>1.4.0-GA</version></dependency></dependencies>3. 創(chuàng)建頁(yè)面
在templates目錄下創(chuàng)建2個(gè)頁(yè)面：
index.html 首頁(yè)
<!DOCTYPE html> <html xmlns:th="http://www.w3.org/1999/xhtml"> <html lang="en"> <head><meta charset="UTF-8"><title>cas-client</title> </head> <body> <h2>Hello：</h2><h2 th:text="${name}"></h2> <a href="/logout">logout</a> </body> </html>logoutsuccess.html 退出后跳轉(zhuǎn)的頁(yè)面
<!DOCTYPE html> <html lang="en"> <head><meta charset="UTF-8"><title>Logout success！ </title> </head> <body> <h1>Logout success！</h1> <a href="/index">back to index</a> </body> </html>4. 創(chuàng)建 Controller
@Controller public class CASController {@Value("${casClientLogoutUrl}")private String clientLogoutUrl;@RequestMapping("index")public String index(ModelMap map, HttpServletRequest request) {//獲取登錄的用戶名map.addAttribute("name", request.getUserPrincipal());return "index";}@RequestMapping("logout")public String logout(HttpSession session) {session.invalidate();return "redirect:" + clientLogoutUrl;}@RequestMapping("logoutsuccess")public String logoutsuccess(HttpSession session) {return "logoutsuccess";} }5. application.properties
server.port=99cas.server-url-prefix=http://127.0.0.1:8080/cas cas.server-login-url=http://127.0.0.1:8080/cas/login cas.client-host-url=http://127.0.0.1:99 cas.use-session=true cas.validation-type=cas# 自定義的退出url casClientLogoutUrl=http://127.0.0.1:8080/cas/logout?service=http://127.0.0.1:99/logoutsuccess6. 創(chuàng)建過(guò)濾器
@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;@Beanpublic FilterRegistrationBean filterAuthenticationRegistration(){FilterRegistrationBean registration = new FilterRegistrationBean();registration.setFilter(new AuthenticationFilter());// 設(shè)定匹配的路徑registration.addUrlPatterns("/*");Map<String,String> initParameters = new HashMap<String, String>();initParameters.put("casServerLoginUrl", serverUrlPrefix);initParameters.put("serverName", clientHostUrl);//忽略的url，"|"分隔多個(gè)url//initParameters.put("ignorePattern", "/logoutsuccess|/index");initParameters.put("ignorePattern", "/logoutsuccess");registration.setInitParameters(initParameters);// 設(shè)定加載的順序registration.setOrder(1);return registration;} }7. 測(cè)試
打開(kāi)首頁(yè)地址：http://localhost:99/index，會(huì)跳轉(zhuǎn)到CAS Server登錄頁(yè)面。這時(shí)候注意看瀏覽器的地址：http://127.0.0.1:8080/cas/login?service=http%3A%2F%2F127.0.0.1%3A99%2Findex，自動(dòng)攜帶的service參數(shù)就是我們剛才訪問(wèn)的頁(yè)面
輸入賬號(hào)密碼，登錄后會(huì)跳轉(zhuǎn)會(huì)前面service的頁(yè)面地址
注意看前面的application.properties，lotout 鏈接我們同樣傳了service參數(shù)，目的是CAS Server單點(diǎn)登出后能夠跳回我們指定的頁(yè)面。
CAS Server默認(rèn)不會(huì)開(kāi)啟登出跳轉(zhuǎn)，需要修改E:\apache-tomcat-8.5.59\webapps\cas\WEB-INF\cas.properties文件，將cas.logout.followServiceRedirects屬性值改成true
成功退出后，CAS會(huì)跳回我們的頁(yè)面
到這里，簡(jiǎn)單的 SpringBoot CAS 客戶端就搭建成功了
總結(jié)
