Java 自动连接sessionfactory时出错

我真的是springmvc的新手，正在努力学习，我真的被这个错误困住了。你可能认为那个问题是重复的，但我搜索了相关的问题，但对我来说不起作用。我得到的错误如下

您应该使用使用Java配置的Spring boot，这比Spring MVC的传统XML设置容易得多，有关更多信息，请查看@AliAdnan感谢您的建议，我知道SpringBoot更容易，但我有一些理由学习SpringMVC。你有hibernate所需的所有依赖项吗？请同时发布您的pom文件。@AbdullahKhan我添加了pom.xml文件。我想您的pom缺少一些必需的依赖项。检查并检查名称空间您所说的名称空间@Mudassari在我的dispatcher servlet.xml文件中有注释驱动和组件扫描代码。我将其复制到appContext.xml，但相同：（这就是我所说的名称空间“”的意思，我所做的一切都没有改变@blafasel
