spring boot整合CAS Client实现单点登陆验证的示例

2021-03-23 13:18牛奋lch JAVA教程

本篇文章主要介绍了spring boot整合CAS Client实现单点登陆验证的示例,小编觉得挺不错的,现在分享给大家,也给大家做个参考。一起跟随小编过来看看吧

本文介绍了spring boot整合CAS Client实现单点登陆验证的示例,分享给大家,也给自己留个笔记,具体如下:

单点登录( Single Sign-On , 简称 SSO )是目前比较流行的服务于企业业务整合的解决方案之一, SSO 使得在多个应用系统中,用户只需要 登录一次 就可以访问所有相互信任的应用系统。

CAS Client

负责处理对客户端受保护资源的访问请求,需要对请求方进行身份认证时,重定向到 CAS Server 进行认证。(原则上,客户端应用不再接受任何的用户名密码等 Credentials )。

实现方式一:使用第三方的starter

1、依赖的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、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);
  
 }
}

通过上面的3步,就可以完成CAS的客户端认证了!

4、扩展

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

具体的含义从名字上就可以很清楚的看出来。

实现方式二:手动配置

我们原来使用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>
 <!-- 该过滤器负责对Ticket的校验工作,必须启用它 -->
 <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>
 <!-- 该过滤器负责实现HttpServletRequest请求的包裹, 比如允许开发者通过HttpServletRequest的getRemoteUser()方法获得SSO登录用户的登录名,可选配置。 -->
 <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,我们手动配置的时候,需要手动配置上面xml中对应的Filter,代码如下:

@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("/*");// 设置匹配的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("/*");// 设置匹配的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("/*");// 设置匹配的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("/*");// 设置匹配的url
 authenticationFilter.setUrlPatterns(urlPatterns);
 return authenticationFilter;
 }
}

通过上面的配置,也可以完成CAS Client的认证
