单点登录_配置客户端与服务器端
单点登陆实现方式
运营中心系统采用Cas（全称是Centeral Authentication Service）做为单点登陆SSO（Single Sign
On）的实现方式。其由Cas Server和Cas Client两部分组成，Cas Server是核心，而Cas
Client一般对应于咱们的应用系统。一个Cas Server能够对应多个Cas
Client。它容许咱们在一个Client进行登陆之后无需再让用户输入用户名和密码进行认证便可访问其它Client应用。
因为运营中心系统和国药健康在线大部分业务系统都使用Spring Security来管理用户、角色和权限。因此须要在各业务系统的Spring
Security应用中整合Cas Client，以达到使用Cas Server实现单点登陆和登出的效果。css
客户端项目配置
- 配置依赖jar包 首先须要将Spring Security对Cas支持的jar包加入到应用的类路径中。若是咱们的应用是用Maven构造的，则能够在应用的pom.xml文件中加上以下依赖。
<!-- Spring Security cas-->
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-cas</artifactId>
<version>3.1.4.RELEASE</version>
</dependency>
<dependency>
<groupId>org.jasig.cas.client</groupId>
<artifactId>cas-client-core</artifactId>
<version>3.2.1</version>
</dependency>
<dependency>
<groupId>net.sf.ehcache</groupId>
<artifactId>ehcache</artifactId>
<version>2.10.0</version>
</dependency>
<!-- Spring Security cas-->
添加证书到信任库
在Cas单点登陆验证过程当中，还须要验证证书，这须要咱们将以前创建的证书导出并添加到当前运行时使用的JRE的证书信任库中。可直接使用以下命令和证书文件导入。
keytool -import cert -alias cas -file cas.crt -keystore
“%JAVA_HOME%\jre\lib\security\cacerts” -storepass changeit –nopromptmysqlHOSTS文件配置 若是Cas
Server、运营中心系统，以及对接业务系统运行在局域网内，没有各自的域名映射，则须要经过修改HOSTS文件配置的方式，添加各个系统的域名映射关系。且除Cas
Server不须要配置本身的域名外，其它各系统域名在各个服务器上均需配置所有域名映射，且各域名映射需保持一致。如测试环境下，运营中心系统的hosts文件配置：git#Cas Server域名
192.168.1.132 cas.suse.server
#项目域名
192.168.1.201 cas.auth.comgithub在web.xml中配置单点监听类web
<listener>
<listener-class>org.jasig.cas.client.session.SingleSignOutHttpSessionListener</listener-class>
</listener>
添加spring-cas.xml单点登录的客户端配置文件
将以前的spring-security.xml配置文件,改为spring-cas.xml配置文件,使spring容器加载单点的配置文件spring
