maven

1.生成钥匙串

Java代码  
keytool -genkey -alias tomcat -keypass changeit -keyalg RSA -keystore server.keystore  

2.生成证书

Java代码  
keytool -export -alias tomcat -keypass changeit -file server.crt -keystore server.keystore  

3.生成服务器认证

Java代码  
keytool -import -alias tomcat -file server.crt -keypass changeit -keystore  cacerts  

4.生成 jre 客户端认证 (切换到 jre 目录，最好在 jdk 和jre 目录下都执行这样 eclipse 跑的项目可以运行)

Java代码  
keytool -import -alias tomcat -file server.crt -keypass changeit -keystore cacerts  

5.查看客户端认证

Java代码  
keytool -list -keystore cacerts  

6.修改服务器端tomcat 配置

部署服务器端：

下载 http://developer.jasig.org/cas/ 下载 cas-server-4.0.0-release.zip

解压后选择 modules /cas-server-webapp-4.0.0.war 放到 tomcat 中修改 server.xml

Java代码  
<Connector protocol="org.apache.coyote.http11.Http11Protocol"   
port="8443" minSpareThreads="5" maxSpareThreads="75"   
enableLookups="true" disableUploadTimeout="true"   
acceptCount="100" maxThreads="200"   
scheme="https" secure="true" SSLEnabled="true"   
keystoreFile="I:/software/tomcat-cas/server.keystore" keystorePass="changeit"  
truststoreFile="I:/software/Java/jdk1.7.0_72/jre/lib/security/cacerts"   truststorePass="changeit"  
clientAuth="false" sslProtocol="TLS"/>  

7. 在 host （C:\Windows\System32\drivers\etc）中添加 host （有代理的项目去掉该代理）

Java代码  
127.0.0.1 sso.baoyou.com   

8.验证服务端部署

https://sso.baoyou.com:8443/

9. 验证客户端

客户端部署：

1. 添加pom

Java代码  
<cas.version>3.1.12</cas.version>  
<dependency>  
            <groupId>org.jasig.cas.client</groupId>  
            <artifactId>cas-client-core</artifactId>  
            <version>${cas.version}</version>  
        </dependency>  

2.添加 web.xml

Java代码  
<!-- ======================== 单点登录开始 ======================== -->  
        <!-- CAS退出url -->  
          <context-param>  
              <param-name>casServerLogoutUrl</param-name>  
              <param-value>https://sso.baoyou.com:8443/cas/logout</param-value>  
          </context-param>  
        <!-- 用于单点退出，该过滤器用于实现单点登出功能，可选配置-->

        </filter-mapping>  
  
        <!-- 该过滤器负责实现HttpServletRequest请求的包裹，

        <!-- ======================== 单点登录结束 ======================== -->  

http://localhost:8083/springmvchibernate/web/user/new

在cas\WEB-INF\deployerConfigContext.xml

中添加用户登陆

Java代码  
<bean id="primaryAuthenticationHandler"  
         class="org.jasig.cas.authentication.AcceptUsersAuthenticationHandler">  
       <property name="users">  
           <map>  
               <entry key="casuser" value="Mellon"/>  
    <entry key="baoyou" value="baoyou"/>  
           </map>  
       </property>
