    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="jdbcUrl" value="jdbc:sqlserver://localhost:1433; DatabaseName=SQL"></property>

< 二 > 使用方式 ( 新增为例 )

package spring.amain;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.jdbc.core.JdbcTemplate;

public class JdbcTest {
    public static void main(String[] args) {
        @SuppressWarnings("resource")
        ApplicationContext ac = new ClassPathXmlApplicationContext("config/spring2jdbc.xml");
        JdbcTemplate jdbcTemplate = (JdbcTemplate) ac.getBean("jdbcTemplate");
        String sql = "insert into [User] (Name) values (?)";
        jdbcTemplate.update(sql, "姓名");
