spring+struts+hibernte 多个表的结构一样

spring+struts+hibernte 多个表的结构一样，不可能为每个表再写xml文件对应的javabean。有没有什么好办法，可以每次把表名传入，并且可以像这样查询：
public NxtvUserInfo QueryNxtvUserInfo(String username,String userpassword,String userflag){
NxtvUserInfo user = null;
String hsql = " from NxtvUserInfo s where s.username='"+username+"' and s.userpassword='"+userpassword+"'" +
"and s.userflag='"+userflag+"'";
List list = this.getHibernateTemplate().find(hsql);
if(list != null && !list.isEmpty()){
user = (NxtvUserInfo) list.get(0);
}
return user;
}
而NxtvUserInfo.hbm.xml为
<?xml version="1.0"?>
