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。请嘘！！

由以下原因引起：org.springframework.beans.factory.NoSuchBeanDefinitionException：没有可用的"com.api.demo.store.FileStorage"类型的合格bean：应至少有1个符合自动连线候选条件的bean。依赖项注释：｛@org.springframework.beans.factory.annotation.Autowired(required=true)，@org.springframework.beans.factory.annination.Qualifier(value=com.api.demo.store.FileStorageMemDB)｝位于org.springframework.beans.factory.support.DefaultListableBeanFactory.raiseNoMatchingBeanFound(DefaultListableBeanFactory.java：1493)位于org.springframework.beans.factory.support.DefaultListableBeanFactory.doResolveDependency(DefaultListableBeanFactory.java：1104)位于org.springframework.beans.factory.support.DefaultListableBeanFactory.resolveDependency(DefaultListableBeanFactory.java：1066)位于org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor$AutowiredFieldElement.inject(AutowiredAannotationBeanpostProcessor.java:585)…还有28个

@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);
}

}

感谢Varren，

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

｛…｝

做到了！！
