我尝试了一个多小时才发现错误，但我仍然无法：

这是错误的样子，我的映射文件：

这是我第一次使用 maven 和 hibernate，所以这个错误对我来说也很糟糕，你能帮帮我吗？
主文件第 20 行是：
Session session = NewHibernateUtil.getSessionFactory().getCurrentSession();
session.beginTransaction();
NewJavaUtil 的 ~31 行是：
}
catch (Throwable ex) {
// Log the exception.
System.err.println("Initial SessionFactory creation failed." + ex);
throw new ExceptionInInitializerError(ex);
}
【问题讨论】：
-
而不是使用 println() 我真的会使用 ex.printStackTrace() 来获取有关异常的更多信息。并且请不要使用 ExceptionInInitializerError，该错误具有非常特定的含义，而这不是它（您可以在 javadocs 中查找）
-
我将
添加到将文件映射到第 5 行，它有助于解决一个错误，但新的错误是：... 1更多原因：org.dom4j.DocumentException：文档第 5 行出错：与元素类型“null”关联的属性“table”的值不得包含“
