在 gradle 多项目 [spring 数据] 中将对象存储库注入到 DataService 失败

Question

我在将存储库注入服务时遇到问题。 这是我春天的第一个项目。 我从这个网站做了一个教程： http://blog.netgloo.com/2014/10/27/using-mysql-in-spring-boot-via-spring-data-jpa-and-hibernate/ 我不知道出了什么问题。我尝试在界面中注释@EnableJpaRepositories，@Repository，但没有帮助我。 所有代码都在我的github上：https://github.com/kklimczak/OpenStudies

堆栈跟踪：

Answer 1

@Transactional @存储库

在您的 SubjectRepository 中使用这两个注释

导入 org.springframework.stereotype.Repository;进口 org.springframework.transaction.annotation.Transactional;
