java - 无法将具有类“java.lang.Long”的对象“20001”转换为类“java.util.Optional”

问题描述

我正在为服务编写 groovy 测试，这是我的 groovy 代码

class SharedListServiceSpec extends Specification {

    private static SharedListService sharedListService
    private static SharedListRepository sharedListRepository
    private static Optional<SharedList> sharedListDetails
    private static List<User> userDetails
    private static Long sharedListId
    Optional<User> userDetails
    private static String sharedListJsonResponse = "{\"sharedListId\":\"20001\",\"sharedListName\":\"Id Sequence3\",\"sharedListType\":\"SharedList\",\"userId\":\"\"100001,\"}"
    private static String message="Successful"

    def void setupSpec(){
        sharedListRepository=Mock()
        sharedListDetails = new ArrayList<>()
        sharedListService = new SharedListService(sharedListRepository)
        sharedListRepository.findById(*_) >> { sharedListId } >> sharedListJsonResponse

    }
def "test sharedList details when sharedListId is not null"() {
        given:
       sharedListId=20001l
        when:
        def sharedListResponse=sharedListService.getListDetail(sharedListId,userDetails)
        then:
        sharedListResponse.getResponseMetaData().message==message
    }
}

服务等级是

public class SharedListService implements ISharedListService{
    private final SharedListRepository sharedListRepository;

    @Override
    public SharedListResponse getListDetail(Long sharedListId, Optional<User> userDetails) {

        SharedListDTO sharedListDTO = SharedListDTO.builder().build();
        Optional<SharedList> sharedList = sharedListRepository.findById(sharedListId);
        if(sharedList.isPresent()){
            SharedList list = sharedList.get();
            if(Objects.nonNull(list)) {
                BeanUtils.copyProperties(list, sharedListDTO);
            }
        }
        return SharedListResponse.builder().sharedList(sharedListDTO).build();
    }
}

得到这样的错误
