Java 需要AnnotationConfiguration实例

我是春天和冬眠的新手。现在我正在尝试将一些数据保存到mySql数据库。但是我得到了一些错误。dispatcher-servelet.xml中是否需要任何配置来使用hibernate注释。我怎样才能解决这个问题

这个班有什么问题吗 EmployeeServiceImpl.java和HibernateUtil.java

public class EmployeeServiceImpl implements EmployeeService {

@Override
public void add(Employee employee) {
//Persist the user object here. 
    Session session = HibernateUtil.getSessionFactory().openSession();
    Transaction transaction = null;
    try {
        transaction = session.beginTransaction();
        session.save(employee);
        transaction.commit();
    } catch (HibernateException e) {
        transaction.rollback();
    } finally {
        session.close();
    }
    System.out.println("User added successfully");
}
}

public class HibernateUtil {
private static final SessionFactory sessionFactory;
static {
    try {
        sessionFactory = new Configuration().configure().buildSessionFactory();
    } catch (Throwable ex) {
        System.err.println("Initial SessionFactory creation failed." + ex);
        throw new ExceptionInInitializerError(ex);
    }
}
public static SessionFactory getSessionFactory() {
return sessionFactory;
}
}

需要添加hibernate注释jar并将sessionFactory构建为

 return new AnnotationConfiguration().configure().buildSessionFactory();

org.hibernate.cfg.AnnotationConfiguration
${jdbc.dial}
${jdbc.showsql}

您可以使用上面的配置，这对我来说很好。

谢谢您的重播，但它不起作用。我正在使用SimpleFormController。我已尝试过，但它显示另一个错误。我在下面的问题中添加了它，“在使用answer New Exception1中的hibernet.cfg.xml后”，它不起作用。如果你愿意，我有什么方法可以向你发送我的代码。压缩代码并将其发送到我的电子邮件id。你不使用Spring配置会话工厂有什么原因吗？
