Spring Security 集成 CAS(基于HTTP协议版本)

Spring Security 集成 CAS(基于HTTP协议版本)

近段时间一直研究Spring Security 集成 CAS，网上资料相关资料也很多，不过大都是基于Https的安全认证;使用https协议方式验证需要创建证书等一系列事情比较繁琐，且证书是自己制作每次导航至登录界面时都会有安全提示给人感觉不太好；所以整理此文档供有需要的同学参考。

一、服务端配置(cas 3.5)

(1).Http协议的CAS比Https版本的步骤要少了ssl的配置，然后修改服务端部分配置文件即可。

(2).配置CAS服务应用程序的配置文件：WEB_INF下cas.properties、deployerConfigContext.xml

以及WEB-INF子目录spring-configuration下的ticketGrantingTicketCookieGenerator.xml、warmCookieGenerator.xml

(3).修改cas.properties

1. # Services Management Web UI Security
2. server.name=http://localhost:8080
3. server.prefix=${server.name}/cas
4. cas.securityContext.serviceProperties.service=${server.prefix}/services/j_acegi_cas_security_check
5. # Names of roles allowed to access the CAS service manager
6. cas.securityContext.serviceProperties.adminRoles=ROLE_ADMINISTRATOR
7. cas.securityContext.casProcessingFilterEntryPoint.loginUrl=${server.prefix}/login
8. cas.securityContext.ticketValidator.casServerUrlPrefix=${server.prefix}
9. # IP address or CIDR subnet allowed to access the /status URI of CAS that exposes health check information
10. cas.securityContext.status.allowedSubnet=127.0.0.1
11. cas.themeResolver.defaultThemeName=cas-theme-default
12. cas.viewResolver.basename=default_views
13. ##
14. # Unique CAS node name
15. # host.name is used to generate unique Service Ticket IDs and SAMLArtifacts. This is usually set to the specific
16. # hostname of the machine running the CAS node, but it could be any label so long as it is unique in the cluster.
17. host.name=cas
18. ##
19. # Database flavors for Hibernate
20. #
21. # One of these is needed if you are storing Services or Tickets in an RDBMS via JPA.
22. #
23. database.hibernate.dialect=org.hibernate.dialect.OracleDialect
24. # database.hibernate.dialect=org.hibernate.dialect.MySQLInnoDBDialect
25. #database.hibernate.dialect=org.hibernate.dialect.HSQLDialect

(4).deployerConfigContext.xml 添加数据源和密码密码编译器Bean验证用户登录信息；

设置不要使用Https方式（p:requireSecure="false"）。

注意：SpringSecurity,CAS 的版本不同有可能类存在不同的包内。
