Hibernate中的MappingNotFoundException [英] MappingNotFoundException in Hibernate

问题描述

我遵循这个教程。

以下是我的文件夹结构：

当我运行App.Java时，我得到：

 创建初始SessionFactory failed.org.hibernate.MappingNotFoundException：资源：com / mkyong / user / DBUser.hbm.xml找不到
  

然而，我可以在那里看到那个文件。当我将该文件放在

  src / main / java / com / mykong / user / DBUser.hbm.xml $ b $下时b  

我仍然遇到这个错误。

谢谢。

编辑：

  hibernate.cfg.xml 
 
 < session-factory> 
 
< property name =connection.url> jdbc：mysql：// localhost：3306 / sampleapplication< / property> 
< property name =connection.driver_class> com.mysql.jdbc.Driver< / property> 
< property name =connection.username> root< / property> 
< property name =connection.password> MYPASSWORDHERE< / property> 
 
< property name =show_sql> true< / property> 
< mapping resource =com / mkyong / user / DBUser.hbm.xml>< / mapping> 
< / session-factory> 
< / hibernate-configuration> 
  

解决方案

明白了：拼写错误： $ c> hiberate.cfg.xml 文件指定hibernate映射文件驻留在以下位置： com / mkyong / user / DBUser.hbm.xml 然而，在包目录结构中它是： com / mykong / user / DBUser.hbm.xml 。注意mykong;不是mkyong。

因此，在hibernate.cfg.xml文件中，请尝试更改

 < mapping resource =com / mkyong / user / DBUser.hbm.xml>< / mapping> 
  

改为：

 < mapping resource =com / mykong / user / DBUser.hbm.xml>< / mapping> 
  

I have followed this tutorial.

Here is my folder structure:

When I run App.Java, I get:

Initial SessionFactory creation failed.org.hibernate.MappingNotFoundException: resource: com/mkyong/user/DBUser.hbm.xml not found

However, I have that file there as you can see it. When I put the file under

src/main/java/com/mykong/user/DBUser.hbm.xml

I am still getting this error.

How can I make this example work?

Thank you.

Edit:

hibernate.cfg.xml

<hibernate-configuration>
    <session-factory>

        <property name="connection.url">jdbc:mysql://localhost:3306/sampleapplication</property>
        <property name="connection.driver_class">com.mysql.jdbc.Driver</property>
        <property name="connection.username">root</property>
        <property name="connection.password">MYPASSWORDHERE</property>

        <property name="show_sql">true</property>
        <mapping resource="com/mkyong/user/DBUser.hbm.xml"></mapping>
    </session-factory>
</hibernate-configuration>

解决方案

Got it: Spelling error: In your hiberate.cfg.xml file you have specified that the hibernate mapping file resides in the location: com/mkyong/user/DBUser.hbm.xml However, in the package directory structure it is: com/mykong/user/DBUser.hbm.xml. Note the mykong; not mkyong.

Therefore, in the hibernate.cfg.xml file, please try changing

<mapping resource="com/mkyong/user/DBUser.hbm.xml"></mapping>

to the following:

<mapping resource="com/mykong/user/DBUser.hbm.xml"></mapping>
