我正在尝试使用Hibernate学习Spring MVC。为此,我试图将一个表单值添加到mysql表中,但有错误。我不知道如何使它工作。我用谷歌搜索了它,但不能为我的工作得到它。请问有人请帮帮我吗?!!!这是我在下面的尝试::
我在WEB-INF / classes文件夹下的hibernate.cfg.xml>>>

我在控制器中的添加方法,我试图将值保存到数据库&gt;&gt;&gt;
@RequestMapping(value="/registration/add", method=RequestMethod.POST)
public void submitAdmissionForm(@ModelAttribute("registrationDT") RegistrationDT registrationDT){
RegistrationDAO registrationDAO = new RegistrationDAO();
registrationDAO.addRegistration(registrationDT);
System.out.println("Saved Successfully.");
}
我的RegistrationDAO&gt;&gt;&gt;
public class RegistrationDAO implements IRegistrationDAO {
RegistrationDT registrationDT = null;
private SessionFactory sessionFactory;
public void addRegistration(RegistrationDT registrationDT){
sessionFactory = new Configuration()
.configure() // configures settings from hibernate.cfg.xml
.buildSessionFactory();
Session session = sessionFactory.openSession();
session.beginTransaction();
session.saveOrUpdate(registrationDT);
session.getTransaction().commit();
session.close();
}
}
我的IRegistrationDAO&gt;&gt;&gt;
public interface IRegistrationDAO {
public void addRegistration(RegistrationDT registrationDT);
}
在提交表单值后,我遇到此错误&gt;&gt;&gt;
HTTP状态500 - 请求处理失败;嵌套异常是org.hibernate.exception.JDBCConnectionException:无法打开连接
任何人都可以帮忙吗???
**完整堆栈跟踪** - 根据需要&gt;&gt;&gt;
