我正在尝试使用两个数据库创建 REST spring应用程序： MySQL 和 MongoDB 。我在弹簧数据中存储库存在问题。我需要一个JPA存储库和一个MongoDB存储库。我不想将它们分开，因为那时我需要将我的分开。
此项目的link。
有8个测试类。 4表示nosql数据库，4表示关系数据库。现在测试关系数据库的工作原理。如果您在CrudRepository中MongoRepository更改com.javaworkspace.repositories，则可以使用nosql数据库测试。
层次结构MongoRepository从CrudRepository延伸，但是当我执行此代码时，我会得到这样的例外情况：
Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.javaworkspace.repositories.MarkRepository] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations:
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'markServiceImpl': Injection of resource dependencies failed; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.javaworkspace.repositories.MarkRepository] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.
