我一直在用Hibernate Integration研究Struts2。当我试图实际实现它时，我得到了以下错误：  错误500：无法实例化在命名空间'/'中为'insertData'定义的Action，java5s.DsTestAction无法从资源TestBean.hbm.xml解析映射文档 我将我的代码放在下面。 我是hibernate的新手，请帮助解决我的问题。如果我的代码出错了，请纠正我。

My Session Factory code

package java5s;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;

public class HiberUtil {
	public static Session getSession(){
		SessionFactory sesfact = new Configuration().configure().buildSessionFactory();
		return sesfact.openSession();
	}

}
