This is because your internet is blocking to get data from that DTD. Just dowbload all DTD which is mention in xml file and in all xml file give location like this.. This works for me
这是因为您的互联网阻止从该 DTD 获取数据。只需下载 xml 文件中提到的所有 DTD，并在所有 xml 文件中给出这样的位置..这对我有用

I was facing the same problem, so i just downloaded that file mentioned in the configuration file and placed it to the path at '/home/ist/Downloads/hibernate-configuration-3.0.dtd' and gave that path to the configuration file and it worked. Hope its helpful for you too.
我遇到了同样的问题，所以我只是下载了配置文件中提到的那个文件，并将它放到了“/home/ist/Downloads/hibernate-configuration-3.0.dtd”的路径中，并将该路径提供给了配置文件和有效。希望它对你也有帮助。

In order to be parsed as xml, your hibernate.cfg.xml should start with:
为了被解析为 xml，你的 hibernate.cfg.xml 应该以：
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
Check following things in hibernate.cfg.xml:
检查 hibernate.cfg.xml 中的以下内容：
- check if there are some blank space or other content before the
<?xml ?> - check if there is another
<?xml ?>definition in hibernate.cfg.xml - check if there is a Byte Order Mark (BOM) before the
<?xml ?>(http://www.w3.org/International/questions/qa-byte-order-mark#remove)
- 检查之前是否有一些空格或其他内容
<?xml ?> - 检查
<?xml ?>hibernate.cfg.xml 中是否还有其他定义 - 检查
<?xml ?>（http://www.w3.org/International/questions/qa-byte-order-mark#remove）之前是否有字节顺序标记（BOM ）

Could you please try with the below configuration details and make sure you have placed the hibernate.cfg.xmlfile under the SRC directory. If you have to placed cfg file other than SRC, you have to specify the path in Configuration() at the time of creating SessionFactory.
您能否尝试使用以下配置详细信息，并确保您已将hibernate.cfg.xml文件放在 SRC 目录下。如果必须放置SRC以外的cfg文件，则必须在创建SessionFactory时在Configuration()中指定路径。
<?xml version="1.0" encoding="UTF-8"?>

I was able to solve what the issue was. The issue was that my hibernate.cfg.xmlfile was not under the "resources"directory within my project.
我能够解决问题所在。问题是我的hibernate.cfg.xml文件不在我的项目中的“资源”目录下。
This solved all the issues I was having, and I did notneed to alter the code within the file.
这解决了所有我遇到的问题，我也没有需要改变的文件中的代码。

Something wrong in the second line of the config file. Try changing the location of the DTD file as follows.
配置文件的第二行有问题。尝试如下更改 DTD 文件的位置。
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-configuration SYSTEM
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
Hope this helps.
希望这可以帮助。

Many Times it Happens because of Internet not Connected on your System.To Work on Hibernate Internet Is Compulsary.
很多时候它发生是因为您的系统上没有连接互联网。在休眠互联网上工作是强制性的。
