Mapping problem with Hibernate
提问by special0ne
I am new to hibernate and i am having trouble with specifying the location of the mapping file in hibernate.cfg.xml file.
我是 hibernate 的新手，在 hibernate.cfg.xml 文件中指定映射文件的位置时遇到问题。
I have created an Event object in org.hibernate.tutorial.chapter1.domain.Event.java package with its corresponding Event.hbm.xml file in the same location.
我在 org.hibernate.tutorial.chapter1.domain.Event.java 包中创建了一个 Event 对象，其对应的 Event.hbm.xml 文件位于同一位置。
I am trying to specify the location in the hibernate.cfg.xml mapping tag but I am getting an InvalidMappingException ().
我试图在 hibernate.cfg.xml 映射标记中指定位置，但我收到了 InvalidMappingException ()。
I have added to the post: the exception, the mapping from the mapping file and the project file structure.
我在帖子中添加了：异常、映射文件和项目文件结构的映射。
any advice would be great.
任何建议都会很棒。

Make sure you have a DOCTYPE in your Event.hbm.xml at the top of the XML content such as:
确保在 XML 内容顶部的 Event.hbm.xml 中有一个 DOCTYPE，例如：
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
<hibernate-mapping package="org.hibernate.tutorial.domain">
[...]
</hibernate-mapping>

My problem was that my XML file was missing :
我的问题是我的 XML 文件丢失了：
<?xml version="1.0" encoding='utf-8'?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
after inserting this to the beginning of the XML file everything turned out great. Thanks!
将此插入到 XML 文件的开头后，一切都变得很好。谢谢！
