NoSuchBeanDefinitionException:没有类型（JpaRepository和Java配置）的限定bean

在过去的几个小时里，我试图启动我的示例web应用程序，但我总是遇到这样的

NoSuchBeanDefinitionException

：(
我有

@EnableJpaRepositories

，我也用

@JpaRepository

试过了！

我创建了一个github存储库，在那里你可以看到整个代码。我希望这对你来说是好的

但这里有一些代码行：

JPA repository（包：root.repository）：

PersistenceConfig（包：root.config）：

---

WebConfig（包：root.config）：
