spring+hibernate 没报错，可就是不能插入数据库，急急急！！

import com.dao.PersonDao;
import com.po.Person;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.FileSystemXmlApplicationContext;

public class PersonDaoTest {
public static void main(String[] args) throws Exception {
ApplicationContext applicationContext=new FileSystemXmlApplicationContext("WebRoot/WEB-INF/classes/applicationContext.xml");
PersonDao personDao=(PersonDao)applicationContext.getBean("personDaoImpl");

Person person=new Person();
person.setAge(22);
person.setName("xqy1");

System.out.println("导入数据开始.......");
personDao.insert(person);
System.out.println("导入数据结束.......");



}
}

配置文件：Person.hbm.xml

"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

运行结果：
log4j:WARN No appenders could be found for logger (org.springframework.context.support.FileSystemXmlApplicationContext).
log4j:WARN Please initialize the log4j system properly.
导入数据开始.......
导入数据结束.......
