DAO文件
public class myDAO extends HibernateDaoSupport implements ImyDAO{

/**

public myDAO() {
// TODO Auto-generated constructor stub
super();
}
private SessionFactory sessionFactory;

public void setSessionFactory(SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory;
}

public void persistinsert(SysUser sysUser) {
//TODO Auto-generated method stub
System.out.println(this.sessionFactory);
System.out.println(sysUser.getUserid());
Session session = this.getSession();
System.out.println(session);

getHibernateTemplate().saveOrUpdate(sysUser);

}
}

上面的sessionfactory打印出来是null,,为什么啊???

不能保存出错
