Question

我今天在公司创建了一个小项目。在Hibernate Perspective中，我尝试添加新配置，以便我可以从具有多个列的db表中轻松创建实体。但是当我选择我的项目时，它会给我org.hibernate.HibernateException: Could not parse configuration: /hibernate.cfg.xml

完成堆栈跟踪 -

即使使用了许多hibernate版本并多次更改DTD，我也无法弄清楚问题。有人可以帮我这个。它是一个简单的maven项目，而.cfg.xml文件放在src / main / java

中

我甚至从这个网址http://www.mkyong.com/hibernate/maven-3-hibernate-3-6-oracle-11g-example-xml-mapping/下载了一个简单的项目，然后尝试添加新配置但又遇到了同样的问题。我只是更改了我拥有的相应数据库凭据。它们是正确的，因为使用相同的jdbc url我已成功在Data Source Explorer中创建了新的数据库连接。请帮助。

互联网在我公司工作正常。

尝试更改hibernate.cfg.xml中的DTD定义：

<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

为：

<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE hibernate-configuration SYSTEM
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

这样，XML解析器不会尝试从Internet加载DTD文件，但会尝试从Hibernate jar加载它。

您可以打开配置文件抛出Web浏览器（firefox），检查您的配置文件是否正常。如果有什么问题，浏览器会向您显示。我指的是（http://blog.csdn.net/caixiexin/article/details/7024623）。
