Hibernate + Spring异常：未知实体 [英] Hibernate + Spring exception: Unknown Entity

问题描述

我在服务器启动时收到异常。 （服务器使用Intelij IDE启动）。
我不知道如何解决它。我是冬眠和春天的新手。

解决方案

谢谢每个人的回复。我设法解决它。这是我的错误。

 < hibernate-configuration> 
< session-factory> 
< mapping class =com.model.Authentication/> //我错过了这一行。我添加后。它工作得很好。 
< / session-factory> 
< / hibernate-configuration> 
  

再次感谢。

i am getting exception while the server starts. (Server is started using Intelij IDE). i have no idea how to fix it. i am new to hibernate and spring. thanks in advance.

解决方案

thanks everyone for your reply. i managed to solve it. it was my mistake. i forgot to add the mapping tag in xml.

<hibernate-configuration>
    <session-factory>
    <mapping class="com.model.Authentication"/> // i missed this line. after i added it. it worked fine.
    </session-factory>
</hibernate-configuration>

thanks again.
