I think the problem is with the many-to-one tag in Student.hbm.xml because Department.hbm.xml and the namedQuery within are not causing an error. What am I doing wrong? I'm using mvn package to make a .war file and then deploy it in tomcat 7.
我认为问题在于 Student.hbm.xml 中的多对一标记，因为 Department.hbm.xml 和其中的 namedQuery 不会导致错误。我究竟做错了什么？我正在使用 mvn 包制作一个 .war 文件，然后将其部署在 tomcat 7 中。

The error Could not parse mapping documentis about your xml files notbeing well-formed. When this error comes up, we'd better double check our xml files to see if they are really OK (all tags are properly closed and so on).
错误Could not parse mapping document是关于您的 xml 文件格式不正确。当这个错误出现时，我们最好仔细检查我们的 xml 文件，看看它们是否真的正常（所有标签都正确关闭等等）。
In your case, as the message states, your Student.hbm.xmlfile is the problem. You have some tags that do not belong:
在您的情况下，正如消息所述，您的Student.hbm.xml文件是问题所在。您有一些不属于的标签：
<property name="firstName" type="string" column="FirstName" />
</property> <------------------------------------------------------ remove this
<property name="lastName" type="string" column="LastName"/>
</property> <------------------------------------------------------ remove this
<property name="program" type="string" column="Program"/>
</property> <------------------------------------------------------ remove this
Those closing </property>tags aren't closing no one, as the <propertytags above them are self-closed (notice the />).
那些结束</property>标签不会关闭任何人，因为<property它们上方的标签是自闭合的（注意/>）。

Try to change hibernate mapping DTD. My problem solves after changing http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtdto http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd
尝试更改休眠映射 DTD。将http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd更改 为 http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd后，我的问题解决了

My problem solves after changing http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtdto http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd. The issue could caused by timeout when access to remote DTD file.
将http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd更改为http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd后，我的问题解决了。该问题可能是由于访问远程 DTD 文件时超时造成的。
I would download the hibernate-mapping-3.0.dtd and make it available locally.
我会下载 hibernate-mapping-3.0.dtd 并使其在本地可用。
回答by Krishna.p
May Be This problem because of Not matching with The variable names used in bean class.
可能是这个问题，因为与 bean 类中使用的变量名不匹配。
For eg. Then Your variable names should be FirstName.
例如。那么你的变量名应该是名字。

In my case was just a comment at the beggining of xml. If someone have a comment like just remove it and maybe will work.
在我的情况下只是在 xml 开始时的评论。如果有人有评论，例如将其删除，也许会起作用。

Please remove <?xml version="1.0"?>from your mapping and config file.It will solve your problem
请<?xml version="1.0"?>从您的映射和配置文件中删除。它将解决您的问题
回答by Ajay Takur
you might have configured multiple times of mapping tag for same entity/persistence.
您可能为同一实体/持久性配置了多次映射标记。

You just close your property like
你只需关闭你的财产就像
<property name="firstName" type="string" column="FirstName" />
or
或者
<property name="firstName" type="string" column="FirstName"></property>
