模拟服务嵌套映射器

Question

我有tje下面的映射器，我使用服务通过代码获取实体

@Mapper(uses = { LevelMaturityService.class, SatisfactionLevelService.class })
public interface EvaluationMapper extends EntityMapper<EvaluationDTO, Evaluation> {
@Mapping(source = "levelMaturity.code", target = "levelMaturity", qualifiedByName = { "levelMaturityService", "getLevelMaturityByCode" } )
@Mapping(source = "satisfactionLevel.code", target = "satisfactionLevel", qualifiedByName = { "satisfactionLevelService", "getSatisfactionLevelByCode" })
Evaluation toEntity(EvaluationDTO evaluationDTO);
}

public class EvaluationMapperTest {

private EvaluationMapper evaluationMapper = InstanceMapperConstant.EVALUATION_INSTANCE;

@Mock
private LevelMaturityService levelMaturityService;

@Mock
private SatisfactionLevelService satisfactionLevelService;

private static EvaluationInit evaluationInit;

@BeforeClass
public static void setUp() throws Exception {
    evaluationInit = new EvaluationInit();
}

@Test
public void givenEvaluationDTO_thenReturnEvaluation() {
    EvaluationDTO evaluationDTO = evaluationInit.buildEvaluationDTOWithId();
    when(levelMaturityService.getOne(evaluationDTO.getLevelMaturity().getCode())).thenReturn(Mockito.any(LevelMaturity.class)); // error
    when(satisfactionLevelService.getOne(evaluationDTO.getSatisfactionLevel().getCode())).thenReturn(Mockito.any(SatisfactionLevel.class));
    Evaluation evaluation = evaluationMapper.toEntity(evaluationDTO);
    assertEquals(evaluationDTO.getBusinessValueGroup(), evaluation.getBusinessValueGroup());
}

}

Answer 1

evaluationDTO.getLevelMaturity().getCode()

这将抛出NullPointerException，因为您从未为它赋值。

在evaluationdTo中设置值。它只是初始化为空。
