Question

任何人都知道为什么hibernate在我的例子中没有创建表？

这是我的web.xml - http://pastebin.com/ZaseSaBS

mvc-dispatcher-servlet.xml - http://pastebin.com/LbdxMSAb

applicationContext.xml - http://pastebin.com/bAHMaVNX

我有几乎相同配置的类似项目，一切似乎在另一个项目上运行得很好。有什么想法，为什么它不在这里创建表格？我在com.calculator.enity中使用@Entity @GeneratedValue注释进行了一次测试，我将它列在persistence.xml文件中。在com.calculator.repository中还有这个实体的JpaRepository

看起来您的持久性配置未正确完成。根据您的要求使用此示例持久性配置。这对我来说很好。
