我如何使用BeanFactory。测试类字段中的getBean（）？

Question

我正在编写测试用例，我想在其中使用相同的BeanFactory.getBean（）实例，只需进行一些小的更改-所以我不想编写例如：Class class=factory.getBean（lass.class）；每次，但我宁愿将其放在私有字段中，并在各种测试用例中使用class变量。

测试类如下所示：

@ExtendWith(SpringExtension.class)
@SpringBootTest
@AutoConfigureMockMvc
@ActiveProfiles(value = "test")
@Import(TestConfiguration.class)
public class FeedbackServiceTest {

  @Autowired
  private BeanFactory beanFactory;

  //I'd like to use this in the various methods:
  private AppUser testSender = beanFactory.getBean("sender", AppUser.class);
  
  //other fields to be cleared up with BeanFactory:
  private final FeedbackRepository feedbackRepository = Mockito.mock(FeedbackRepository.class);
  private final AppUserRepository appUserRepository = Mockito.mock(AppUserRepository.class);
  private final ValueRepository valueRepository = Mockito.mock(ValueRepository.class);
  private final FeedbackService feedbackService = new FeedbackServiceImpl(feedbackRepository, appUserRepository,
      valueRepository);
  private final AppUser testTarget = new AppUser("someUserDatas"));
  private final Value testValue = new Value("someValueDatas");
  private final Feedback testFeedback = new Feedback(testSender, testValue, testTarget, "otherDatas");

  @Test
  public void saveNewFeedback_WithValidParams_ShouldSaveFeedback() {

    Mockito.when(appUserRepository.findById(testSender.getId()))
        .thenReturn(Optional.of(testSender));
    Mockito.when(appUserRepository.findById(testTarget.getId()))
        .thenReturn(Optional.of(testTarget));
    Mockito.when(valueRepository.findById(testValue.getId()))
        .thenReturn(Optional.of(testValue));
    feedbackService.saveNewFeedback(testFeedback);
    Mockito.verify(feedbackRepository, times(1)).save(Mockito.any(Feedback.class));
  }

TestConfiguration类是这样的：

@Configuration
public class TestConfiguration {

  @Bean(name = "sender")
  @Scope(value = ConfigurableBeanFactory.SCOPE_PROTOTYPE)
  public AppUser getAppUser() {
    return new AppUser("Pista", "[e-mail]", Gender.MALE, "p123_ABC", "USER",
        LocalDate.parse("1967-10-12"));
  }
}

如果我将私有AppUser testSender=beanFactory。getBean（“sender”，AppUser.class） 行，它运行良好，否则会抛出null点异常

如果我理解正确，那么您的要求是在每个方法中使用testSender的引用。为此，我建议您在FeedbackServiceTest中使用@beforeach：

public class FeedbackServiceTest {
    @Autowired
      private BeanFactory beanFactory;
    
      //I'd like to use this in the various methods:
      private AppUser testSender;
    
      
      @BeforeEach
      public void setBean(){
       testSender= beanFactory.getBean("sender", AppUser.class);
      }
...//rest other class
