Spring Security 集成 CAS(基於HTTP協議版本)

近段時間一直研究Spring Security 集成 CAS，網上資料相關資料也很多，不過大都是基於Https的安全認證;使用https協議方式驗證需要創建證書等一系列事情比較繁瑣，且證書是自己制作每次導航至登錄界面時都會有安全提示給人感覺不太好；所以整理此文檔供有需要的同學參考。

一、服務端配置(cas 3.5)
(1).Http協議的CAS比Https版本的步驟要少了ssl的配置，然後修改服務端部分配置文件即可。
(2).配置CAS服務應用程序的配置文件：WEB_INF下cas.properties、deployerConfigContext.xml
以及WEB-INF子目錄spring-configuration下的ticketGrantingTicketCookieGenerator.xml、warmCookieGenerator.xml
(3).修改cas.properties
Sql代碼

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
13. cas.themeResolver.defaultThemeName=cas-theme-default
14. cas.viewResolver.basename=default_views
16. ##
17. # Unique CAS node name
18. # host.name is used to generate unique Service Ticket IDs and SAMLArtifacts. This is usually set to the specific
19. # hostname of the machine running the CAS node, but it could be any label so long as it is unique in the cluster.
20. host.name=cas
22. ##
23. # Database flavors for Hibernate
24. #
25. # One of these is needed if you are storing Services or Tickets in an RDBMS via JPA.
26. #
27. database.hibernate.dialect=org.hibernate.dialect.OracleDialect
28. # database.hibernate.dialect=org.hibernate.dialect.MySQLInnoDBDialect
29. #database.hibernate.dialect=org.hibernate.dialect.HSQLDialect

(4).deployerConfigContext.xml 添加數據源和密碼密碼編譯器Bean驗證用戶登錄信息；
設置不要使用Https方式（p:requireSecure="false"）。
註意：SpringSecurity,CAS 的版本不同有可能類存在不同的包內。
