spring boot整合CAS Client实现单点登陆验证的示例

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>

<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
