    	<context:component-scan base-package="com.fehead.spring.jdbc"></context:component-scan>
    
    	
    	
    	<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
    		<property name="username" value="xiaoaxiao"></property>
    		<property name="password" value="8023hyx1999hyx"></property>
    		<property name="url" value="jdbc:mysql://localhost:3306/spring1"></property>
    		<property name="driverClassName" value="com.mysql.jdbc.Driver"></property>
    	</bean>
    	
    	
    	<bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
    		<property name="dataSource" ref="dataSource"></property>
    	</bean>
    	
    	
    	
    </beans>

最重要的一段是：  
  
设置bean的时候，每一个property的name必须设置正确（和下面的一模一样）  
username  
password  
url  
driverClassName
