我正在 Netbeans IDE 中使用HibernateTemplate进行我的第一个Spring + Hibernate集成示例。导入所有spring和hibernate相关的jar，包括 ojdbc14.jar 。
我已在Oracle 12G数据库中创建了一个名为 userstable 的表，该表的列名与我的model / POJO类中声明的属性相同。
我在Glassfish服务器窗口中粘贴了错误的主要部分/警告。以下是错误：

DAO接口实施类：
package DataDAO;
import Model.User;
import org.springframework.orm.hibernate4.HibernateTemplate;
public class UserDAOImplementationHT implements UserDAO{
private HibernateTemplate ht;
public void setHt(HibernateTemplate ht) {
this.ht = ht;
}
public UserDAOImplementationHT() {
}
@Override
public void registerAnUser(User newuser) {
ht.save(newuser);
}
}
服务层接口实施类：
package DataService;
import DataDAO.UserDAO;
import Model.User;
import org.springframework.context.ConfigurableApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class DataServiceImplementation implements DataService{
ConfigurableApplicationContext cap = new ClassPathXmlApplicationContext("applicationContext.xml");
UserDAO daoob = (UserDAO) cap.getBean("ddd");
@Override
public void registerAnUser(User newuser) {
daoob.registerAnUser(newuser);
}
}
控制器类
@Controller
public class NewController extends MultiActionController{
DataService dataservice;
@RequestMapping("/register.htm")
public ModelAndView regUser(HttpServletRequest request, HttpServletResponse response) throws ParseException {
if(request.getParameter("regPassword").equals(request.getParameter("regConfrimPass"))){
String myDateFormat = request.getParameter("date1");
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-mm-dd");
Date dateofbirth = sdf.parse(myDateFormat);
User newUser = new User(request.getParameter("email"),request.getParameter("regPassword"),request.getParameter("regFirstname"),request.getParameter("regLastname"),request.getParameter("regUniversityname"),Long.parseLong(request.getParameter("regPhonenum")),dateofbirth);
dataservice.registerAnUser(newUser);
return new ModelAndView("SuccessPage");
}
else {
return new ModelAndView("FailurePage");
}
}
}
有谁可以帮我解决这个错误？我一直试图通过引用互联网上的几种资源来解决这个问题，但在每一次尝试都失败了。
提前致谢。
