小妹请教下关于spring，初学，请前辈帮帮忙

我就想用spring实现一个简单的查询显示
这是我的applicationContext.xml
总感觉连接数据库写的错的，不知道可不可以这样写


<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd" >
<beans>
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
<property name="driverClassName">
<value>net.sourceforge.jtds.jdbc.Driver</value>
</property>
<property name="url">
<value>jdbc:jtds:sqlserver://localhost:1433;DatabaseName=sap_finance</value>
</property>
<property name="username">
<value>sa</value>
</property>
<property name="password">
<value>123</value>
</property>
</bean>
<bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
<property name="dataSource">
<ref local="dataSource"/>
</property>
</bean>

<bean id="testDao" class="com.test.dao.testDao">
<property name="jdbcTemplate">
<ref local="jdbcTemplate"/>
</property>
</bean>
</beans>

这是我的后台

public class testCmd extends testDao implements Controller{
public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response)
throws Exception{
JdbcTemplate jdbcTemplate =getJdbcTemplate();
String sql="select * from test";
List sqlList=jdbcTemplate.queryForList(sql);
request.setAttribute("sqlList", sqlList);
return new ModelAndView("test/test.jsp");
}
}

然后运行报错：
java.lang.NullPointerException
com.test.cmd.testCmd.handleRequest(testCmd.java:20)
org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter.handle(SimpleControllerHandlerAdapter.java:45)
org.springframework.web.servlet.DispatcherServlet.doDispatch(DispatcherServlet.java:820)
org.springframework.web.servlet.DispatcherServlet.doService(DispatcherServlet.java:755)
org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:396)
org.springframework.web.servlet.FrameworkServlet.doGet(FrameworkServlet.java:350)
javax.servlet.http.HttpServlet.service(HttpServlet.java:617)
javax.servlet.http.HttpServlet.service(HttpServlet.java:717)



请前辈们帮忙看看！到底是哪里错了呢？感激不尽！！！
