spring+hibernate开发问题!

[zhouonline]

我在调试程序时出现以下错误:
HibernateSystemException异常Hibernate.executeHibernateCallback,boolean)行,391.hibernate.save()
spring配置文件如下:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">

<beans>

</property>
</bean>
<bean id="StudentDAO" class="jou.model.StudentDAO">
<property name="sessionFactory">
<ref local="sessionFactory"/>
</property>
</bean>



</beans>


接口如下:package jou.model;


public interface IStudentDAO {
public void savepeople(people id) ;

}

DAO类:
package jou.model;

import org.apache.log4j.Logger;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;


public class StudentDAO extends HibernateDaoSupport implements IStudentDAO{
private SessionFactory sessionFactory;

static Transaction tx = null;
static Logger log = Logger.getLogger(StudentDAO.class);
public void savepeople(people id)
{
this.getHibernateTemplate().save(id);
}



}
main主函数调用StudentDAO
package jou.model;

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

public class Test {
public static void main(String ars[]) {
ApplicationContext ctx = new FileSystemXmlApplicationContext("src/applicationContext.xml");
StudentDAO dao = (StudentDAO)ctx.getBean("StudentDAO");
people pe=new people();
pe.setId(1234);
pe.setUser("ffffffffffffffffff");
dao.savepeople(pe);
System.out.println("fffffffffffffffffffffffff");
}

}
其中要补充的是我调用dao的savapeople()函数就出现异常!这是什么原因,大家请帮帮忙!!

跟这个无关..我已经调试好..配置文件问题.多了一个空格就不行了..

[zqpsswh]

public class StudentDAO extends HibernateDaoSupport implements IStudentDAO{
private SessionFactory sessionFactory;

static Transaction tx = null;
static Logger log = Logger.getLogger(StudentDAO.class);
public void savepeople(people id)
{
this.getHibernateTemplate().save(id);
}



}

去掉 private SessionFactory sessionFactory;

static Transaction tx = null;
