使用Hibernate工具Session工厂时出错

Question

我得到 org.hibernate.MappingException：找不到实体类：公司

在我的Spring MVC项目中，我已经使用注释映射了类，我使用了Hibernate。我安装并配置了Hibernate Tools以使用HSql编辑器和映射图。映射图打开，但Hsql编辑器不会运行。在Hibernate代码生成配置中，我只导出了XML映射和XML配置。我该如何解决这个问题，以便Hsql编辑器可以工作？

我通过Hibernate Tools中的编辑启动配置属性添加了映射。

更新：当我右键单击我的类文件（开源文件）时hibernate =＆gt; Configuration =＆gt;公司（或任何其他类文件）hibernate抛出错误：无法找到源文件。< / em>但如果我点击Mapping文件就会打开。

这是hibernate cfg文件，它位于src文件夹中： 更新：

    <?xml version="1.0" encoding="UTF-8"?>

这是我的 Company.hbm.xml ，它位于 com.web.handyman.entity包中：

这是休眠错误：
