关于Spring jdbctemplate的问题

Question

dao层是这么写的：
public List<Laws> getLawsList(List<Laws> laws, int pageNo, int pageSize) {
// TODO Auto-generated method stub
LawsrowMapper rowMapper = new LawsrowMapper();
String sql = "select id,docName,time,date from laws where type=? order by time desc limit ?,?";
String type = "法律法规";
int page1 = pageNo*pageSize;//上线
int page2 = (pageNo - 1) * pageSize;//下限
Object[] params = {type,page2,page1};
laws = this.jdbcTemplate.query(sql, params, rowMapper);
return laws;
}
spring-dao.xml文件是这么写的：
<!-- 定义使用C3P0连接池的数据源 -->
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<!-- 指定连接数据库的JDBC驱动 -->
<property name="driverClass">

 </property>

</property>
<!-- 设置数据库连接池的连接的最大空闲时间,单位为秒 -->

</property>
</bean>

<bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
   <property name="dataSource" ref="dataSource"></property>
</bean>

<!-- 法律法规dao层 -->
<bean id="lawsDao" class="com.crm.code.dao.Laws.Impl.LawsDaoImpl">
  <property name="jdbcTemplate" ref="jdbcTemplate"></property>
</bean>
</beans>错误提示：
