由于第一个小程序就用到了关于spring的jdbc连接的问题，所以jdbc驱动，不用讲了，导吧。
表字段：表account---->id，userName，password
applicationContext.xml

SpringTest.java
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class SpringTest {
public static void main(String[] args) {
// 很古老的加载方式
//Resource resource = new ClassPathResource("applicationContext.xml");
//BeanFactory factory = new XmlBeanFactory(resource);
ApplicationContext beanFactory = new ClassPathXmlApplicationContext(
"applicationContext.xml");
AccountFind af = (AccountFind)beanFactory.getBean("login");
System.out.println(af.isLogin("brj", "是"));
}
}
去试试，行吧？
