问题描述
我知道这个问题已经被问了很多，但我几乎读了其中的每一个，但是他们中没有一个帮助我。
我正在用hibernate编写一个eclipse maven项目，并且出现这个错误：
org.hibernate。 InvalidMappingException：无法从资源ir / ac / ut / ieproj / da / Student.hbm.xml解析映射文档
我的文件是这样的：

我认为问题出在Student.hbm.xml中的多对一标签，因为Department.hbm.xml和namedQuery内不会导致错误。我究竟做错了什么？我使用mvn包来生成一个.war文件，然后在tomcat 7中进行部署。 $ c>无法解析映射文档是关于您的xml文件 not 格式良好。当出现这个错误时，我们最好仔细检查我们的xml文件，看看它们是否真的好（所有标签都已正确关闭等等）。
就你的情况而言，正如消息所述，你的 Student.hbm.xml 文件是问题所在。您有一些不属于的标签：
< property name =firstNametype =stringcolumn =FirstName />
< / property> < ------------------------------------------------ ------删除此
<属性名称=lastNametype =stringcolumn =LastName/>
< / property> < ------------------------------------------------ ------删除这个
< property name =programtype =stringcolumn =Program/>
< / property> < ------------------------------------------------ ------删除此
那些关闭< / property> 标签不会关闭任何人，因为上面的< property 标签是自封闭的（注意 / > ）。
I know this question has been asked a lot, but I read almost every one of them but non of them helped me. I'm writing an eclipse maven project with hibernate and I'm getting this error:
org.hibernate.InvalidMappingException: Could not parse mapping document from resource ir/ac/ut/ieproj/da/Student.hbm.xml

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.
解决方案
The error Could not parse mapping document is about your xml files not being 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).
In your case, as the message states, your Student.hbm.xml file is the problem. You have some tags that do not belong:
<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 <property tags above them are self-closed (notice the />).
