1 @H_403_4@实验环境
1.1 CAS Server端
FreeBSD + Diablo-JDK
IP地址：192.168.0.180
域名：www.test.com
1.2 CAS Client 端
Windows + JDK
IP地址：192.168.0.116
1.3 CAS Server 端数据验证的数据库
IP 地址192.168.0.180
表名称：citizen
表定义：
CREATE TABLE citizen
(
citizenid character varying(20) NOT NULL,
"password" character varying NOT NULL,160) none repeat scroll 0% 0%; -moz-background-clip: -moz-initial; -moz-background-origin: -moz-initial; -moz-background-inline-policy: -moz-initial;"> question character varying,160) none repeat scroll 0% 0%; -moz-background-clip: -moz-initial; -moz-background-origin: -moz-initial; -moz-background-inline-policy: -moz-initial;"> answer character varying,160) none repeat scroll 0% 0%; -moz-background-clip: -moz-initial; -moz-background-origin: -moz-initial; -moz-background-inline-policy: -moz-initial;"> name character varying NOT NULL,160) none repeat scroll 0% 0%; -moz-background-clip: -moz-initial; -moz-background-origin: -moz-initial; -moz-background-inline-policy: -moz-initial;"> CONSTRAINT citizen_pkey PRIMARY KEY (citizenid)
)
说明：其中citizenid用于登录的ID，”password”用于密码校验
2 @H_403_4@环境搭建
2.1 CAS 服务器端
在%JAVA_HOME%/jre/lib/security目录下运行如下Shell文件
#!/bin/csh
clear
keytool -delete -alias tomcatsso -keystore cacerts -storepass changeit
keytool -list -keystore cacerts -storepass changeit
keytool -genkey -keyalg RSA -alias tomcatsso -dname "cn=www.test.com" -keystore cacerts -storepass changeit
keytool -export -alias tomcatsso -file tomcatsso.crt -keystore cacerts -storepass changeit
keytool -import -alias tomcatsso -file tomcatsso.crt -keystore cacerts -storepass changeit
keytool -list -keystore cacerts -storepass changeit
说明：在生成key的过程，"cn=www.test.com" 中的www.test.com为Server端的域名。
将cacerts文件复制到TOMCAT的conf目录下
修改server.xml
<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="443" />
<Connector port="443" minSpareThreads="5" maxSpareThreads="75"
enableLookups="true" disableUploadTimeout="true"
acceptCount="100" maxThreads="200"
scheme="https" secure="true" SSLEnabled="true"
clientAuth="false" sslProtocol="TLS"
keystoreFile="conf/cacerts" keystorePass="changeit"
truststoreFile="conf/cacerts"/>
启动Tomcat，测试https://www.test.com:443
2.2 CAS客户端
复制tomcatsso.crt 文件到%JAVA_HOME%/jre/lib/security
将证书tomcatsso.crt 文件导入到cacerts文件中
keytool -import -alias tomcatsso -file tomcatsso.crt -keystore cacerts -storepass changeit
3 @H_403_4@配置
3.1 服务器端
将下载的cas-server-webapp-
在WEB-INF目录下修改deployerConfigContext.xml文件
将原来的
<bean class="org.jasig.cas.authentication.handler.support.SimpleTestUsernamePasswordAuthenticationHandler" />
修改为
<bean class="org.jasig.cas.adaptors.jdbc.QueryDatabaseAuthenticationHandler">
<property name="dataSource" ref="dataSource" />
<property name="sql" value="select password from citizen where citizenid = ?" />
</bean>
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
<property name="driverClassName">
<value>org.postgresql.Driver</value>
</property>
<property name="url">
<value>jdbc:postgresql://192.168.0.180:5432/bh_portal</value>
</property>
<property name="username">
<value>pgsql</value>
</property>
<property name="password">
<value>javac</value>
</bean>
其目的是将原来的SimpleTestUsernamePasswordAuthenticationHandler认证改为根据数据库数据进行认证。
3.2 客户端应用
partner1和partner2
Partner1下建立子目录secure，在secure中写2个测试页面，debug.jsp和index.jsp。
编辑web.xml
<?xml version="1.0" encoding="ISO-8859-1"?>

<url-pattern>/secure/*</url-pattern>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</web-app>
编辑spring-appContext.xml文件
在/WEB-INF/classes目录下创建spring-appContext.xml文件
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">
<bean id="casAuthenticationFilter"
class="org.jasig.cas.client.authentication.AuthenticationFilter">
<property name ="casServerLoginUrl" value="https://www.test.com:443/cas-server/login"/>
<property name ="serverName" value="http://192.168.0.116:8080"/>
</bean>
<bean id="casValidationFilter"
class="org.jasig.cas.client.validation.Cas20ProxyReceivingTicketValidationFilter">
<property name="ticketValidator">
<ref bean="Cas20ServiceTicketValidator"/>
</property>
<property name="useSession" value="true"/>
<property name="serverName" value="http://192.168.0.116:8080"/>
<property name="redirectAfterValidation" value="false"/>
</bean>
<bean id="Cas20ServiceTicketValidator" class="org.jasig.cas.client.validation.Cas20ServiceTicketValidator">
<constructor-arg index="0" value="https://www.test.com:443/cas-server" />
<bean id="casHttpServletRequestWrapperFilter"
class="org.jasig.cas.client.util.HttpServletRequestWrapperFilter"/>
</beans>
复制所需JAR包
cas-client-core-
同partner1完全相同
配置index.jsp的Gateway参数
设置Gateway参数为false（默认值为false）
web.xml文件：
保持原有无需改变
spring-appContext.xml文件：
给AuthenticationFilter对应的Bean添加一个属性gateway，并显式的设置为false
<property name ="gateway" value="false"/>
配置debug.jsp的Gateway参数
设置Gateway参数为true（默认值为false）
web.xml文件：
为debug.jsp独立配置上面spring-appContext.xml文件中所提及到的3个过滤器AuthenticationFilter,Cas20ProxyReceivingTicketValidationFilter,HttpServletRequestWrapperFilter。
spring-appContext.xml文件：
给AuthenticationFilter对应的Bean添加一个属性gateway，并设置值为true
<property name ="gateway" value="true"/>
