创建名称为'repository. BookRepositoryTest'的bean时出错

Question

我正在为spring数据存储库编写junit测试。但我不能自动连接存储库界面。如果我运行main方法，则程序正在运行，spring可以检测所有存储库、服务和实体，但如果我运行html" target="_blank">测试，则会出现以下错误：

UnsatisfiedDependencyException：创建名为“repository”的bean时出错。BookRepositoryTest:通过字段“bookRepository”表示的未满足的依赖关系；嵌套异常为org。springframework。豆。工厂NoSuchBeanDefinitionException：没有类型为“app”的合格bean。存储库。BookRepository可用：至少需要1个符合autowire候选条件的bean。依赖项注释：{@org.springframework.beans.factory.annotation.Autowired（必需=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：

    main
        java
            app
                entity
                    Book.java

Answer 1

我也面临着类似的问题。我使用@MockBean注释注入了依赖类。

@MockBean
private S3StorageService s3StorageService;

上述解决方案对我有效。

Answer 2

您可以按以下方式使用BookRepository

@EnableAutoConfiguration
@ContextConfiguration(classes = {BookRepository .class})
public class BookRepositoryTest{
}

Answer 3

问题是，您的主包和测试包不同：

BookRepository在app.entity.repository中，您的测试在repository中。尝试对齐它并将您的测试移动到src/test/java/app/body/repository。
