Cas Server配置说明

yxixi

　　由于项目由多个应用组成，因此需要采用SSO。参考SSO开源软件，最终采用cas 耶鲁开源系统，该系统使用比较广泛，有问题可以进行结合网上教程使用。
　　
　　1.下载cas server 版本 cas-server-3.5.1-release.zip
　　2.解压 cas-server-3.5.1-release.zip，把 cas-server-webapp导入myeclipse。
　　3.把cas-server-core的源文件也导入myeclipse，和第二步合同一个工程
　　4.把cas-server-webapp-3.5.1.war中的内容导入到工程的webroot下面
　　5.把webroot的classes的配置文件放到新的src目录下面
　　6.由于不采用https方式，需要修改配置文件
　　WEB-INF/deployerConfigContext.xml
< bean class = "org.jasig.cas.authentication.handler.support.HttpBasedServiceCredentialsAuthenticationHandler"     p:httpClient-ref = "httpClient" />
增加参数 p:requireSecure="false" ，是否需要安全验证，即 HTTPS ， false 为不采用 如下：
< bean class = "org.jasig.cas.authentication.handler.support.HttpBasedServiceCredentialsAuthenticationHandler" p:httpClient-ref = "httpClient" p:requireSecure= "false" />
 
WEB-INF/spring-configuration/ticketGrantingTicketCookieGenerator.xml 
 
< bean id = "ticketGrantingTicketCookieGenerator" class = "org.jasig.cas.web.support.CookieRetrievingCookieGenerator"
       p:cookieSecure = " false "
       p:cookieMaxAge = "-1"
       p:cookieName = "CASTGC"
 
       p:cookiePath = "/cas" />
 
WEB-INF\spring-configuration\warnCookieGenerator.xml
 
< bean id = "warnCookieGenerator" class = "org.jasig.cas.web.support.CookieRetrievingCookieGenerator"
       p:cookieSecure = " false "
       p:cookieMaxAge = "-1"
       p:cookieName = "CASPRIVACY"
 
       p:cookiePath = "/cas" />
 
7.添加数据库验证用户名和密码
在WEB-INF/spring-configuration/applicationContext.xml添加
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
<property name="driverClassName"  value="com.mysql.jdbc.Driver"></property>   
<property name="url" value="jdbc:mysql://10.18.11.100:3306/rm?autoReconnect=true"></property>    
<property name="username" value="root"></property>   
<property name="password" value="111111"></property>   
</bean>
 
<bean id="loginMonitor" class="com.inspur.sso.LoginMonitor" p:dataSource-ref="dataSource" />
<bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
        <property name="dataSource" ref="dataSource"/>
 
    </bean>
　　8.在WEB-INF\deployerConfigContext.xm添加自定义验证类
　　<property name="authenticationHandlers">
　　<list>
　　
　　<bean class="org.jasig.cas.authentication.handler.support.HttpBasedServiceCredentialsAuthenticationHandler"
　　p:httpClient-ref="httpClient" />
　　
　　<bean class="com.zhb.sso.Auth" >
　　<property name="jdbcTemplate" ref="jdbcTemplate"/>
　　</bean>
　　</list>
　　</property>
　　9.Auth方法：
　　

public class Auth extends AbstractUsernamePasswordAuthenticationHandler {
private JdbcTemplate jdbcTemplate;
public JdbcTemplate getJdbcTemplate() {
return jdbcTemplate;
}
public void setJdbcTemplate(JdbcTemplate jdbcTemplate) {
this.jdbcTemplate = jdbcTemplate;
}
@Override
protected boolean authenticateUsernamePasswordInternal(
UsernamePasswordCredentials credentials)
throws AuthenticationException {
// TODO Auto-generated method stub
final String username = credentials.getUsername();
final String password = credentials.getPassword();
String sql="select * from user where USER_ID=? and PASSWORD=?";
List list=jdbcTemplate.queryForList(sql, new String[]{username,password});
if(list!=null&&list.size()>0){
Map map=(Map)list.get(0);
log
.debug("User [" + username
+ "] was successfully authenticated.");
System.out.println(map.get("USER_NAME"));
return true;
}else{
return false;
}

}
}
　　
　　
　　cas客户端配置
　　1.新建新的web工程test
　　添加cas-client-core-3.2.1.jar及相关jar包
　　修改web.xml

　　在浏览器中输入：http://localhost:8090/test进行测试
　　
　　
　　注意：AuthenticationManagerImpl 所有的验证hander类型都在此类中进行调用，代理类。
