我在我的 spring boot 项目中集成了 LightAdmin 插件，但是运行这个项目会抛出异常。例外是 必须存在至少一个 JPA 元模型。我基本上在 pom.xml 中添加了 springjpa 依赖 spring-boot-starter-data-jpa，但同样的异常抛出。我无法理解，如何解决这些问题请帮助......

I faced similar issue. I solved it by

  1. Creating new configuration class containing @EnableJpaRepositories & @EntityScan
  2. Remove @EnableJpaRepositories & @EntityScan from root application class
