Question

我正在为spring数据存储库编写一个junit测试。但是我不能自动装配仓库接口。如果我运行主要方法并且spring可以检测到所有存储库，服务，实体，则程序正在运行，但是如果我运行测试，则会出现此错误：UnsatisfiedDependencyException：创建名称为'repository.BookRepositoryTest'的bean时出错：通过字段'bookRepository'表示的不满意依赖关系;嵌套的异常是org.springframework.beans.factory.NoSuchBeanDefinitionException：没有类型为'app.repository.BookRepository'的合格Bean：至少应有1个可以作为自动装配候选的Bean。依赖注释：{@ org.springframework.beans.factory.annotation.Autowired（required = true）}

@RunWith(SpringRunner.class)
@SpringBootTest(classes={BookRepository.class})
public class BookRepositoryTest
{
    @Autowired
    private BookRepository bookRepository;
    @Test
    public void save()
    {
        Book book=new Book();
        bookRepository.save(book);
    }
}

public interface BookRepository extends JpaRepository<Book,Integer>
{
    Book findByName(String name);
}

项目结构：

Answer 1

问题是，您的主要和测试软件包不同：

BookRepository在app.entity.repository中，而测试在repository中。尝试对齐它，然后将测试移至src/test/java/app/entity/repository。

Answer 2

您可以通过以下方式使用 BookRepository

class FileLoadingScreen(QDialog, Ui_FileLoadingScreen):
    def __init__(self, loading_gif_path, parent=None):
        super(FileLoadingScreen, self).__init__(parent)

        self.setupUi(self)
        self.setWindowModality(QtCore.Qt.ApplicationModal)

        # Setting up the loading.gif animation.
        self.movie = QMovie(loading_gif_path)
        self.loading_label.setMovie(self.movie)

        self.setAttribute(QtCore.Qt.WA_TranslucentBackground, True)
        self.setWindowFlags(QtCore.Qt.FramelessWindowHint)

    def start_animation(self, width, height, geometry):

        self.resize(width, height)
        self.setGeometry(geometry)
        self.movie.start()
        self.show()

    def stop_animation(self):

        self.movie.stop()
        self.close()
