SpringBoot JPA测试bean不在上下文中

Question

我想不通..出于某种原因，Spring Junit没有将我的bean添加到上下文中。请砰！！

由：org.springframework.beans.factory.nosuchBeanDefinitionException引起：没有类型为“com.api.demo.store.FileStorage”的合格bean可用：需要至少有1个bean作为autowire候选bean。依赖项注释：{@org.springframework.beans.factory.annotation.autowire(required=true)，@org.springframework.beans.factory.annotation.qualifier(value=com.api.demo.store.fileStorageMDB)}org.springframework.beans.factory.support.defaultListableBeanFactory.resolveDependency（DefaultListableBeanFactory.java:1066)在org.springframework.beans.factory.annotation.autowiredNotationBeanPostProcessor$autowiredFieldElement.inject(AutowiredNotationBeanPostProcessor.java:585)...28更多

@RunWith(SpringRunner.class)
@SpringBootTest
public class FileStorageMemDBTest {

    @Autowired
    private TestEntityManager entityManager;

    @Autowired
    private FileStorage fileStorage;

    @Autowired private ApplicationContext ctx;

    @Test
    public void testRetrieveAll() {



        FileInfo fileInfo = new FileInfo("fileOne", "GoodFile.txt", "test");

       entityManager.persist(fileInfo);
            fileStorage.retrieveAllFiles();

    }
}



@Service
public interface FileStorage {
    /**
     * Stores file in an underlying file store
     *
     * @param File     to store
     * @param FileInfo file submission metadata
     */
    public void store(MultipartFile mFile, FileInfo info) throws IOException;

    /**
     * Retrieves a list of all file
     *
     * @return array containing file metadata
     */
    public List<FileInfo> retrieveAllFiles();

    /**
     * Retrieve file metadata by id
     *
     * @return file metadata if found
     * @Param id of a file to retrieve
     */
    public FileInfo retrieveFileMetadata(Long id);
}

   /**
 * Database implementation of FileStorage interface
 *
 */
@Transactional
@Service
public class FileStorageMemDB implements FileStorage {

    @PersistenceContext
    private EntityManager entityManager;

    @Override
    public void store(MultipartFile incomingFile, FileInfo info) throws IOException {

        ......

        entityManager.persist(info);
    }

    @Override
    public List<FileInfo> retrieveAllFiles() {

        return entityManager.createNamedQuery("query_find_all_records", FileInfo.class).getResultList();
    }


    @Override
    public FileInfo retrieveFileMetadata(Long id) {
        return entityManager.find(FileInfo.class, id);
    }


}

谢谢瓦伦，

@RunWith(SpringRunner.class)
@SpringBootTest(classes = Application.class)
public class FileStorageMemDBTest 

{...}

做到了。！！
