CAS SSO研究二：cas_server通过查询数据库验证用户名密码正确性

Posted 2023-02-10 ycyk_168

1、 jar包准备，因为习惯使用bonecp数据源：

mysql jdbc驱动：mysql-connector-java-5.1.13-bin.jar

cas jdbc支持：cas-server-support-jdbc-3.4.11.jar

数据源：bonecp-0.7.1.RELEASE.jar、guava-r09.jar

2、编辑：WEB-INF\\deployerConfigContext.xml，加入数据源：

<bean id="dataSource" class="com.jolbox.bonecp.BoneCPDataSource" destroy-method="close">
		   <property name="driverClass" value="com.mysql.jdbc.Driver" />
		   <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/dbname?useUnicode=true&characterEncoding=UTF-8" />
		   <property name="username" value="root"/>
		   <property name="password" value="root"/>
		   <property name="idleConnectionTestPeriod" value="60"/>
		   <property name="idleMaxAge" value="240"/>
		   <property name="maxConnectionsPerPartition" value="30"/>
		   <property name="minConnectionsPerPartition" value="10"/>
		   <property name="partitionCount" value="3"/>
		   <property name="acquireIncrement" value="5"/>
		   <property name="statementsCacheSize" value="100"/>
		   <property name="releaseHelperThreads" value="3"/>
		</bean>

将默认的规则验证方式注释，并加入新的验证：

	<!--
				<bean
					class="org.jasig.cas.authentication.handler.support.SimpleTestUsernamePasswordAuthenticationHandler" />
				-->
				<bean class="org.jasig.cas.adaptors.jdbc.QueryDatabaseAuthenticationHandler">
				 <property name="dataSource" ref="dataSource" />
				 <property name="sql" 
					    value="select password from gg_user where loginname = ?" />
				 <property  name="passwordEncoder"  ref="passwordEncoder"/>
				</bean>

其中passwordEncoder，我使用的是自定义的encoder：

<bean id="passwordEncoder" 
            class="xx.xx.security.PassWordEncoder"/>

import org.jasig.cas.authentication.handler.PasswordEncoder;
import org.springframework.security.authentication.encoding.ShaPasswordEncoder;

public class PassWordEncoder implements PasswordEncoder 

	@Override
	public String encode(String args) 
		ShaPasswordEncoder encoder = new ShaPasswordEncoder();
		encoder.setEncodeHashAsBase64(true);
		return encoder.encodePassword(args, null);
	
	

至此即实现了cas_server通过查询数据库验证用户名、密码正确性
