org.hibernate.InvalidMappingException：无法解析来自资源的映射文档* .hbm.xml

我知道这个问题已经被问了很多，但我几乎读了其中每一个，但他们中没有人帮助过我。 我正在写与Hibernate一个eclipse的maven项目，我得到这个错误：org.hibernate.InvalidMappingException：无法解析来自资源的映射文档* .hbm.xml

org.hibernate.InvalidMappingException: Could not parse mapping document from resource ir/ac/ut/ieproj/da/Student.hbm.xml

我的文件是这样的：

我认为这个问题是许多到一标记在Student.hbm.xml中，因为Department.hbm.xml和namedQuery内不会导致错误。我究竟做错了什么？我正在使用mvn软件包制作一个.war文件，然后将其部署到tomcat 7.

错误Could not parse mapping document是关于您的xml文件而不是是格式良好的。当这个错误出现时，我们最好仔细检查我们的xml文件，看看它们是否确实正确（所有标签都已正确关闭等）。

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。您有不属于某些标签：

<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

那些关闭</property>标签不关闭任何人，因为<property标签上面他们是自我封闭（注意/>）。

后，我猜它的有关文件和语法，所以我检查20次，但找不到任何错误。猜猜需要第二个人来为我检查，谢谢 –

可能是因为与Bean类中使用的变量名称不匹配而导致此问题。

例如， 然后你的变量名应该是名字。

你只要闭上你的财产像

<property name="firstName" type="string" column="FirstName" />

或

<property name="firstName" type="string" column="FirstName"></property>

在我的例子只是一个在XML的beggining评论。 如果有人有评论就像删除它，也许会工作。

请从您的映射和配置文件中删除<?xml version="1.0"?>。它将解决您的问题

您可能已经为相同的实体/持久性配置了多次映射标记。
