几个小时以来，我一直在尝试测试一个控制器的行为。问题是我必须模拟仓库，它总是变成null。
通过结构视图，我有一个控制器，它有两个注入的服务，这些服务使用两个不同的存储库。
因此，我可以测试我的控制器和我的服务逻辑行为，我必须模拟存储库对一些查询的响应。
我试图实现它像下面：

@WebMvcTest({ WorkspaceRestController.class })
@Tag(Tags.COMPONENT)
@ActiveProfiles(PfSpringProfiles.TEST)
public class WorkspaceRestControllerTest {

    @Autowired
    private MockMvc mockMvc;

    @MockBean
    private IWorkSpaceRepository workSpaceRepository;

    @MockBean
    private IExpertSystemRepository expertSystemRepository;

    @InjectMocks
    private IExpertSystemService expertSystemService;

    @InjectMocks
    private IAsyncWorkService asyncWorkspaceService ; 

    @InjectMocks
    private IWorkspaceService workspaceService;

    @InjectMocks
    WorkspaceRestController workspaceRestController;

    @BeforeAll
    public void intTests() {
    }

    @Test
    public void checkRetrievedContentIsNotnull() throws Exception {

        // Given
        Mockito.when(workSpaceRepository.getAllWorkspaces())
                .thenReturn(new WorkSpaceRepositoryMock().getAllWorkspaces(WorkSpaceRepositoryMock.CASE_FULL));
        Mockito.when(expertSystemRepository.getAllLockedEsByWsId(WorkSpaceRepositoryMock.FIRST_WORKSPACE_ID))
                .thenReturn(new ExpertSystemRepositoryMock()
                        .getAllLockedEsByWsId(WorkSpaceRepositoryMock.FIRST_WORKSPACE_ID));
        Mockito.when(expertSystemRepository.getAllLockedEsByWsId(WorkSpaceRepositoryMock.SECOND_WORKSPACE_ID))
                .thenReturn(new ExpertSystemRepositoryMock()
                        .getAllLockedEsByWsId(WorkSpaceRepositoryMock.SECOND_WORKSPACE_ID));
        Mockito.when(expertSystemRepository.getAllLockedEsByWsId(WorkSpaceRepositoryMock.THIRD_WORKSPACE_ID))
                .thenReturn(new ExpertSystemRepositoryMock()
                        .getAllLockedEsByWsId(WorkSpaceRepositoryMock.THIRD_WORKSPACE_ID));

        // When

        MvcResult result = mockMvc.perform(get("/rest/v2/ws-list")).andExpect(request().asyncStarted()).andDo(print())
                .andReturn();

        // Then
        mockMvc.perform(asyncDispatch(result)).andDo(print());
        // .andExpect( content().string(mapper.writeValueAsString(fullWorkspaceResponseSet)));

    }

}

然而，每当我启动JUnit测试时，workSpaceRepository总是空的。
我该怎么办？
在我的控制器、服务和存储库的代码下面

工作区储存库

@Repository
public interface IWorkSpaceRepository extends JpaRepository<Workspace, Long> {

    /**
     * This method fetches the list of all available workspaces. It could return an empty list.
     *
     * @return List<Workspace> The list of all workspaces found
     */
    @Transactional
    @Modifying(clearAutomatically = false)
    @Query(value = "SELECT ws from Workspace ws JOIN FETCH ws.configuration")
    List<Workspace> getAllWorkspaces();
}

工作区服务

@Service
public class WorkspaceServiceImp implements IWorkspaceService {

    private static final Logger LOGGER = LoggerFactory.getLogger(WorkspaceServiceImp.class);

    private static final String ERROR_AT_DELETE_WORKSPACE_METHOD = "Error at deleteWorkspace() method";
    private static final String ERROR_AT_CREATE_WORKSPACE_METHOD = "Error at createWorkspace() method";

    @Autowired
    private IWorkSpaceRepository workSpaceRepository;

    @Autowired
    private WorkspaceMapper workspaceMapper;

    @Autowired
    private IExpertSystemService expertSystemService;

    @Autowired
    private IPatternInfosService patternInfosService;

    @Autowired
    private IPatternFieldsService patternFieldsService;

    @Autowired
    private IConfigurationService configurationService;

// service methods implementation is ommited
}

该控制器

@RestController
@RequestMapping(path = "/rest/ws/")
@Api("WS Service Rest")
@Validated
public class WorkspaceRestController implements RestApiPing {

    private static final Logger LOGGER = LoggerFactory.getLogger(WorkspaceRestController.class);

    @Autowired
    private IWorkspaceService workspaceService;

    @Autowired
    private AsyncWorkspaceService asyncWorkspaceService;
 // rest api definition here omited   
 }

我得到的堆栈跟踪：
