而且我的应用程序类，如下：

@SpringBootApplication
public class Application {

    public static void main(String[] args) {
        //For Starting application
        ApplicationContext applicationContext=SpringApplication.run(Application.class, args);


    }
}

我的应用程序类是在包。我把MySQL的实体和Neo4j的实体在不同的软件包（MySQL的：。projectone.mysql *和Neo4j的：projectone.entities.neo4j *）。

我的应用程序的包结构如下图所示：

科库，服务和实施是如下：

@Repository
public interface BranchRepository extends Neo4jRepository<Branch,Long> 

@Service
public interface BranchService 

@Service
public class BranchServiceImplementaion implements BranchService

我收到以下错误：
