我已经阅读了整个stackoverflow.Did没有设法创建一个bean既没有找到appConfig.xml文件，依赖就在那里，并且尝试了不同的方法来自@EnableJpaRepository

请帮忙。

Answer 1

你已经在pom中定义了spring-boot-starter-data-jpa依赖两次。也许本地回购破坏了hibernate-entity- * jar。删除maven local repo并重试。

Answer 2

在ServersApplication课程中，还会移除@EnableAutoConfiguration注释。它已包含在@SpringBootApplication中您可以在documentation

中阅读更多内容

@SpringBootApplication注释等同于使用 @Configuration，@ EnableAutoConfiguration和@ComponentScan与他们的默认属性

更进一步，您可以非常轻松地检查使用哪些依赖项创建的bean。有两种方法。通过使用ListableBeanFactory接口或弹簧启动执行器。检查this tutorial如何执行此操作。如果您使用执行器解决方案，您还可以查看endpoints的文档以获取更多信息

Answer 3

好吧，我找到了为什么我的应用程序无法运行的原因。 entityManagerFactory与声明的数据库表中的@Id基列一起使用。我不需要，所以我没有使用它，但在添加它之后它工作了

由于'entityManagerFactory'而无法启动
