Java Spring Boot JPA启动器的Spring Boot启动问题,java,spring,jpa,spring-boot,spring-data-jpa,Java,Spring,Jpa,Spring Boot,Spring Data Jpa,当我试图用springbootstarter数据jpa启动我的springboot项目时，我遇到了这个奇怪的错误。奇怪的是，我的应用程序会在我添加几个存储库和服务之前启动，但我似乎无法解释为什么spring不能初始化在添加之前工作的存储库 以下是相关错误： 11:38:42.313 INFO org.hibernate.Version.logVersion() @37 [localhost-startStop-1] - HHH000412: Hibernate Core {5.0.11.Fin

当我试图用
springbootstarter数据jpa
启动我的springboot项目时，我遇到了这个奇怪的错误。奇怪的是，我的应用程序会在我添加几个存储库和服务之前启动，但我似乎无法解释为什么spring不能初始化在添加之前工作的存储库

以下是相关错误：

请注意用粗体字体标记的文本：

Spring数据存储库通常从
存储库
或
crudepository
接口扩展。如果您使用的是自动配置，则将从包含主配置类的包（用
@EnableAutoConfiguration
或
@SpringBootApplication
注释的包）向下搜索存储库

-

实际上，我认为这就是问题的解决方案（用粗体字标记的文本）：

默认情况下，SpringBoot将启用JPA存储库支持，并查看
@SpringBootApplication
所在的包（及其子包）如果配置的JPA存储库接口定义位于不可见的包中，则可以使用
@EnableJpaRepositories
及其类型安全
basePackageClasses=MyRepository.class
参数来指出备用包

-

<>总而言之，考虑更新<代码> LeeTraces类如下：

@EnableJpaRepositories(basePackageClasses = UserRepository.class)
public class LeetTournaments {
    ...
}
希望这有帮助。

你能发布你的数据源配置吗Spring无法启动Hibernate出于某种原因，很可能是你的Hibernate配置或Spring JPA配置有问题。我添加了数据源配置，这个配置在过去一直有效。我应该在哪里进一步配置Spring JPA？@AndrewD，你能发布
gg.leet.security.WebSecurityConfig
类的实现吗？@SergeyBrunov我添加了相关类-感谢你帮我看一下。所以经过仔细检查，我发现我的一个模型的密钥冲突，这就是我收到的错误。我一直很感激——我花了几天的时间来追踪这个。希望即使有调试标志，也能对ORM有更多的了解。@AndrewD，这是个好消息。我认为你应该把这个解决方案作为一个单独的答案分享，并把它标记为被接受的答案。
