In hibernate configuration file you missed out the mapping element for your hbm file.you should define like in your hibernate.cfg.xml..
在 hibernate 配置文件中，您错过了 hbm 文件的映射元素。您应该在 hibernate.cfg.xml 中定义类似的内容。

I think that you have to add a mapping for your Tbluser.hbm.xml in your hibernate cfg
我认为你必须在你的 hibernate cfg 中为你的 Tbluser.hbm.xml 添加一个映射

It sounds like the xml parser is trying to access the schema or dtd mentioned in the configuration file and fails to succeed.
听起来 xml 解析器正在尝试访问配置文件中提到的架构或 dtd，但未能成功。
Make sure your application has access to http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtdor get the document from there put it somewhere where your application can access it add change the path in the document accordingly
确保您的应用程序可以访问http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd或从那里获取文档 将它放在您的应用程序可以访问它的某个地方 添加相应地更改文档中的路径
