test類:
public class test {
public static void main(String[] args)
{
ApplicationContext ctx=new ClassPathXmlApplicationContext("applicationContext.xml");
Person p=new Person();
p.setId("id8457564");
p.setUsername("admin");
p.setPassword("password");
operate op=(operate)ctx.getBean("persondaoProx");
op.insert(p);
}
