一、实现步骤：

1、 将CentralAuthenticationServiceImpl.java拷贝到org.jasig.cas包下；

2、修改validateServiceTicket方法

**在**

**final** Authenticationauthentication = serviceTicket

.getGrantingTicket().getChainedAuthentications().get(authenticationChainSize- 1);

**final** Principal principal =authentication.getPrincipal();

**后面加入如下代码：**

/\*\*\*\*\*\*\*\*\*\*\*\*\*新增部分开始\*\*\*\*\*\*\*\*\*\*\*\*\*\*/

//取得用户名

String username = principal.getId();

Map<String, Object> attrs = principal.getAttributes();  //其他属性值

String user\_id = (String) attrs.get("fdObjectid"); //用户id

//截取网址前半段，如http://www.a.com:8080/UserManage/xxx/bbb只截取到UserManage

String url = service.toString();

**int** index = url.indexOf("/", url.indexOf("/", 8)+1);

String myUrl = url.substring(0, index+1);

// 看是否有权限，根据实际情况进行修改

String sql = "SELECT count(\*) as myCountfrom sys\_pro\_user s "

+ "where s.pro\_id in("

+ "select pro\_id from sys\_prowhere pro\_url like '%"

\+ myUrl+ "%' and is\_del=0) "

\+ "and s.user\_id = '" \+ user\_id + "'";

// + "and s.user\_id in("

// + "select fd\_objectid from user\_infowhere user\_name='"

// + username+"' andis\_del=0) ";

List xx = getJdbcTemplate().queryForList(sql);

**long** count = (Long)((Map) xx.get(0)).get("myCount");

**if**(count==0)\{

**throw  new**TicketValidationException(serviceTicket.getService());

3、让类继承AbstractJdbcUsernamePasswordAuthenticationHandler

4、修改方法类型为public class CentralAuthenticationServiceImpl

5、 在cas-servlet.xml加入如下代码：

<beanid=*"centralAuthenticationService"*class=*"org.jasig.cas.CentralAuthenticationServiceImpl"*

p:ticketGrantingTicketExpirationPolicy-ref=*"grantingTicketExpirationPolicy"*

p:serviceTicketExpirationPolicy-ref=*"serviceTicketExpirationPolicy"*

p:authenticationManager-ref=*"authenticationManager"*

p:ticketGrantingTicketUniqueTicketIdGenerator-ref=*"ticketGrantingTicketUniqueIdGenerator"*

p:ticketRegistry-ref=*"ticketRegistry"*

p:servicesManager-ref=*"servicesManager"*

p:persistentIdGenerator-ref=*"persistentIdGenerator"*

p:uniqueTicketIdGeneratorsForService-ref=*"uniqueIdGeneratorsMap"*

p:dataSource-ref=*"dataSource"*/>

6、 在cas-servlet.xml添加dataSource的代码如下：

<beanid=*"dataSource"*class=*"org.springframework.jdbc.datasource.DriverManagerDataSource"*>

<propertyname=*"driverClassName"*><value>com.mysql.jdbc.Driver</value></property>

<propertyname=*"url"*><value>jdbc:mysql://localhost:3306/wlw</value></property>

<propertyname=*"username"*><value>root</value></property>

<propertyname=*"password"*><value>root</value></property>

</bean>

7、修改用户查询方式：修改deployerConfigContext.xml文件中的<bean class="org.jasig.cas.adaptors.jdbc.QueryDatabaseAuthenticationHandler">

改为如下所示（可根据实际情况进行修改）：

<bean class="org.jasig.cas.adaptors.jdbc.QueryDatabaseAuthenticationHandler">   
<property name="dataSource" ref="dataSource"></property>  
  
  
<property name="sql" value="select pass\_word from user\_info where user\_name=? and is\_del=0 and role\_id in(select role\_id from sys\_pro\_role where pro\_id=?)"></property>  
  
<property name="passwordEncoder" ref="MD5PasswordEncoder"></property>  
</bean>

注意：*dataSource中的配置可以在配置文件cas.propertie中进行配置*

注意：

a)dataSource的配置可以在配置文件cas.propertie中进行配置;

b)cas客户端需要对不符合登录条件的500错误进行拦截。
