无法将Spring Data MongoDB+Spring DataJPA与SpringBoot一起使用

Question

当我尝试将Spring Data JPA和Spring Data MongoDB与SpringBoot一起使用时，假设我的Mongo实体也是JPA实体并抛出错误。

我有PersonJPA实体和扩展JpaRepository的PersonRepository。我有UserMongoEntity和UserRepository，它们扩展了MongoRepository。

当我启动应用程序时，我得到以下错误：

这方面有什么工作吗？

您应该将Mongo和JPA实体放在单独的包中（看起来您已经这样做了），然后使用@EnableMongoRepositories(basePackageClasses=SomeMongoEntity.class)和@EnableJpaRepositories(basePackageClasses=SomeJpaEntity.class)，这样SpringData就知道在哪里可以分别找到Mongo和JPA实体。您可以在SpringBoot的MixedMongoRepositoriesAutoConfigurationTests中看到这些注释的作用。
