java - Spring数据和错误NoClassDefFoundError ScanEnvironment

Question

我使用 Controller 、服务、dao 层创建了 spring web 应用程序，这有效，但我想将我的 dao 层替换为 spring data jpa，但是当我从 spring data 运行新项目时，在创建对象存储库时，我在浏览器中收到错误。使用 DriverManagerDataSource 或使用 HikariConfig 时出现错误。

HTTP 状态 500 - 请求处理失败；嵌套异常为 org.springframework.beans.factory.BeanCreationException:创建时出错 在configuration.AppConfig中定义名称为“entityManagerFactory”的bean: 调用init方法失败；嵌套异常为 java.lang.NoClassDefFoundError: org/hibernate/boot/archive/scan/spi/ScanEnvironment

我认为“Spring data”中的错误是因为当我将 dao 替换为 jpa 时出现错误，而使用 dao 时效果很好。

这是我的 pom.xml 中的依赖项

This is likely a duplicate.

我所做的是在我的本地 maven 存储库 ~/.m2/repositoryode 中 grep -ir 'ScanEnvironment' . 。幸运的是，有一个匹配./org/hibernate/hibernate-entitymanager/5.0.3.Final/hibernate-entitymanager-5.0.3.Final.jar。根据 hibernate-entitymanager-5.0.3.Final.pom 你需要这个

    <dependency>
      <groupId>org.hibernate</groupId>
      <artifactId>hibernate-core</artifactId>
      <version>5.0.3.Final</version>
      <scope>compile</scope>
    </dependency>
