Question

我正在运行我的Spring Boot应用程序，但是它给了我与EntityManagerFactory相关的错误。我应该创建自己的EntityManager吗？它不包含在spring-boot-starter-data-jpa

中吗

说明：

Field instanceRepository in com.qualityclouds.qcforoffice365.service.Office365InstanceServiceImpl required a bean named 'entityManagerFactory' that could not be found.

操作：

考虑在您的配置中定义一个名为'entityManagerFactory'的bean。

@SpringBootApplication

public class Qcforoffice365Application {

    public static void main(String[] args) {

        ApplicationContext ctx = SpringApplication.run(Qcforoffice365Application.class, args);

        Driver driver = (Driver) ctx.getBean("QCDriver");

        driver.run();

    }
}


@Repository
public interface Office365InstanceRepository extends CrudRepository<Office365InstanceConfiguration, String> {

}

@Service
public class Office365InstanceServiceImpl implements Office365InstanceService {

    @Autowired
    private Office365InstanceRepository instanceRepository;

    @Override
    public Office365InstanceConfiguration findById(String id) {
        return instanceRepository.findById(id).orElse(null);
    }

}

这里是package structure

最后，我找到了解决方案。我只需要删除.m2中的存储库，然后再试一次即可。猜猜这与其他项目的依赖性有关。
