怎么在springboot中利用CASClient实现单点登陆验证-创新互联
怎么在spring boot中利用CAS Client实现单点登陆验证？很多新手对此不是很清楚，为了帮助大家解决这个难题，下面小编将为大家详细讲解，有这方面需求的人可以来学习下，希望你能有所收获。
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
net.unicon.cas cas-client-autoconfig-support 1.4.0-GA
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：
authenticationFilter org.jasig.cas.client.authentication.AuthenticationFilter casServerLoginUrl http://127.0.0.1/login serverName http://192.26.4.28:8080 authenticationFilter /* validationFilter org.jasig.cas.client.validation.Cas20ProxyReceivingTicketValidationFilter casServerUrlPrefix http://127.0.0.1 serverName http://192.26.4.28:8080 validationFilter /* httpServletRequestWrapperFilter org.jasig.cas.client.util.HttpServletRequestWrapperFilter httpServletRequestWrapperFilter /*
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 initParameters = new HashMap();
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 urlPatterns = new ArrayList();
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 initParameters = new HashMap();
initParameters.put("casServerUrlPrefix", "http://127.0.0.1");
initParameters.put("serverName", "http://192.26.4.28:8080");
authenticationFilter.setInitParameters(initParameters);
authenticationFilter.setOrder(1);
List urlPatterns = new ArrayList();
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 urlPatterns = new ArrayList();
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 urlPatterns = new ArrayList();
urlPatterns.add("/*");// 设置匹配的url
authenticationFilter.setUrlPatterns(urlPatterns);
return authenticationFilter;
}
