我克隆了你的项目，找到了你的问题所在。

Spring Data JPA允许您只定义存储库接口，并将在编译时自动为它们生成实现（感谢注释处理器）。但是要做到这一点，您需要使用@EnableJpaRepository注释：

@Configuration
@EnableWebMvc
@ComponentScan(basePackages = "com.websystique.springmvc")
@EnableJpaRepositories(basePackages = "com.websystique.springmvc")
public class HelloWorldConfiguration {
    ...
}

使用此注释，现在将找到存储库并将其注入到其他bean中（如MainController）。

webapp仍然无法启动，因为现在JPA存储库希望找到类型为EntityManager和TransactionManager的bean，这是您必须提供的，但让我们将此保存为另一个问题：）
