本篇文章主要介紹了spring boot整合CAS Client實(shí)現(xiàn)單點(diǎn)登陸驗(yàn)證的示例，小編覺(jué)得挺不錯(cuò)的，現(xiàn)在分享給大家，也給大家做個(gè)參考。一起跟隨小編過(guò)來(lái)看看吧

本文介紹了spring boot整合CAS Client實(shí)現(xiàn)單點(diǎn)登陸驗(yàn)證的示例，分享給大家，也給自己留個(gè)筆記，具體如下：

單點(diǎn)登錄（ Single Sign-On , 簡(jiǎn)稱(chēng) SSO ）是目前比較流行的服務(wù)于企業(yè)業(yè)務(wù)整合的解決方案之一， SSO 使得在多個(gè)應(yīng)用系統(tǒng)中，用戶(hù)只需要登錄一次就可以訪問(wèn)所有相互信任的應(yīng)用系統(tǒng)。

CAS Client

負(fù)責(zé)處理對(duì)客戶(hù)端受保護(hù)資源的訪問(wèn)請(qǐng)求，需要對(duì)請(qǐng)求方進(jìn)行身份認(rèn)證時(shí)，重定向到 CAS Server 進(jìn)行認(rèn)證。（原則上，客戶(hù)端應(yīng)用不再接受任何的用戶(hù)名密碼等 Credentials ）。

實(shí)現(xiàn)方式一：使用第三方的starter

1、依賴(lài)的jar

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

2、增加配置文件

cas.server-url-prefix=http://127.0.0.1 
cas.server-login-url=http://127.0.0.1/login 
cas.client-host-url=http://192.26.4.28:8080 
cas.validation-type=CAS

3、開(kāi)啟CAS Client支持

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

通過(guò)上面的3步，就可以完成CAS的客戶(hù)端認(rèn)證了！

4、擴(kuò)展

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

其他可用的配置如下：

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

具體的含義從名字上就可以很清楚的看出來(lái)。

實(shí)現(xiàn)方式二：手動(dòng)配置

我們?cè)瓉?lái)使用CAS Client，需要在web.xml中做如下配置：

<filter> 
 <filter-name>authenticationFilter</filter-name> 
 <filter-class>org.jasig.cas.client.authentication.AuthenticationFilter</filter-class> 
 <init-param> 
  <param-name>casServerLoginUrl</param-name> 
  <param-value>http://127.0.0.1/login</param-value> 
 </init-param> 
 <init-param> 
  <param-name>serverName</param-name> 
  <param-value>http://192.26.4.28:8080</param-value> 
 </init-param> 
 </filter> 
 <filter-mapping> 
 <filter-name>authenticationFilter</filter-name> 
 <url-pattern>/*</url-pattern> 
 </filter-mapping> 
 <!-- 該過(guò)濾器負(fù)責(zé)對(duì)Ticket的校驗(yàn)工作，必須啟用它 --> 
 <filter> 
 <filter-name>validationFilter</filter-name> 
 <filter-class>org.jasig.cas.client.validation.Cas20ProxyReceivingTicketValidationFilter</filter-class> 
 <init-param> 
  <param-name>casServerUrlPrefix</param-name> 
  <param-value>http://127.0.0.1</param-value> 
 </init-param> 
 <init-param> 
  <param-name>serverName</param-name> 
  <param-value>http://192.26.4.28:8080</param-value> 
 </init-param> 
 <!-- <init-param> 
  <param-name>redirectAfterValidation</param-name> 
  <param-value>true</param-value> 
 </init-param> 
 <init-param> 
  <param-name>useSession</param-name> 
  <param-value>true</param-value> 
 </init-param> --> 
 </filter> 
 <filter-mapping> 
 <filter-name>validationFilter</filter-name> 
 <url-pattern>/*</url-pattern> 
 </filter-mapping> 
 <!-- 該過(guò)濾器負(fù)責(zé)實(shí)現(xiàn)HttpServletRequest請(qǐng)求的包裹， 比如允許開(kāi)發(fā)者通過(guò)HttpServletRequest的getRemoteUser()方法獲得SSO登錄用戶(hù)的登錄名，可選配置。 --> 
 <filter> 
 <filter-name>httpServletRequestWrapperFilter</filter-name> 
 <filter-class>org.jasig.cas.client.util.HttpServletRequestWrapperFilter</filter-class> 
 </filter> 
 <filter-mapping> 
 <filter-name>httpServletRequestWrapperFilter</filter-name> 
 <url-pattern>/*</url-pattern> 
 </filter-mapping>

所以，我們手動(dòng)配置的時(shí)候，需要手動(dòng)配置上面xml中對(duì)應(yīng)的Filter，代碼如下：

@Configuration 
@Component 
public class CasConfigure { 
 
 @Bean 
 public FilterRegistrationBean authenticationFilterRegistrationBean() { 
 FilterRegistrationBean authenticationFilter = new FilterRegistrationBean(); 
 authenticationFilter.setFilter(new AuthenticationFilter()); 
 Map<String, String> initParameters = new HashMap<String, String>(); 
 initParameters.put("casServerLoginUrl", "http://127.0.0.1/login"); 
 initParameters.put("serverName", "http://192.26.4.28:8080"); 
 authenticationFilter.setInitParameters(initParameters); 
 authenticationFilter.setOrder(2); 
 List<String> urlPatterns = new ArrayList<String>(); 
 urlPatterns.add("/*");// 設(shè)置匹配的url 
 authenticationFilter.setUrlPatterns(urlPatterns); 
 return authenticationFilter; 
 } 
 
 @Bean 
 public FilterRegistrationBean ValidationFilterRegistrationBean(){ 
 FilterRegistrationBean authenticationFilter = new FilterRegistrationBean(); 
 authenticationFilter.setFilter(new Cas20ProxyReceivingTicketValidationFilter()); 
 Map<String, String> initParameters = new HashMap<String, String>(); 
 initParameters.put("casServerUrlPrefix", "http://127.0.0.1"); 
 initParameters.put("serverName", "http://192.26.4.28:8080"); 
 authenticationFilter.setInitParameters(initParameters); 
 authenticationFilter.setOrder(1); 
 List<String> urlPatterns = new ArrayList<String>(); 
 urlPatterns.add("/*");// 設(shè)置匹配的url 
 authenticationFilter.setUrlPatterns(urlPatterns); 
 return authenticationFilter; 
 } 
 
 @Bean 
 public FilterRegistrationBean casHttpServletRequestWrapperFilter(){ 
 FilterRegistrationBean authenticationFilter = new FilterRegistrationBean(); 
 authenticationFilter.setFilter(new HttpServletRequestWrapperFilter()); 
 authenticationFilter.setOrder(3); 
 List<String> urlPatterns = new ArrayList<String>(); 
 urlPatterns.add("/*");// 設(shè)置匹配的url 
 authenticationFilter.setUrlPatterns(urlPatterns); 
 return authenticationFilter; 
 } 
 
 @Bean 
 public FilterRegistrationBean casAssertionThreadLocalFilter(){ 
 FilterRegistrationBean authenticationFilter = new FilterRegistrationBean(); 
 authenticationFilter.setFilter(new AssertionThreadLocalFilter()); 
 authenticationFilter.setOrder(4); 
 List<String> urlPatterns = new ArrayList<String>(); 
 urlPatterns.add("/*");// 設(shè)置匹配的url 
 authenticationFilter.setUrlPatterns(urlPatterns); 
 return authenticationFilter; 
 } 
}

通過(guò)上面的配置，也可以完成CAS Client的認(rèn)證
