Question

我正在尝试对SpringBoot应用程序进行单元测试。正常的应用程序执行工作正常，但由于缺少依赖项，我无法执行我的测试。我尝试了很多注释组合，我也尝试了@ContextConfiguration（我认为这可能是“问题”），但我无法让它工作。我试图在我的@ContextConfoguration aqnnotation中包含Locker.class，但这对alsp没有帮助。你能帮助我吗？这是我的测试类的摘录：

@RunWith(SpringRunner.class)
@SpringBootTest
@ContextConfiguration
public class LockerServiceImplTest {

  @InjectMocks
  private LockerServiceImpl service;

  @Mock
  private LockerRepository repo;

  @Autowired
  private Locker locker;

  @Test
  public void testPersist() {

    this.locker.setAppId("mytestappid");
    this.locker.setId(0);
    this.locker.setLastActivityTimestamp(System.currentTimeMillis());
    this.locker.setLocked(true);

    // configure the mocks
    Mockito.doNothing().when(this.repo).update(this.locker.getLastActivityTimestamp(), true);
    Mockito.doNothing().when(this.repo).update(this.locker.getLastActivityTimestamp(), false);
    Mockito.when(this.repo.save(this.locker)).thenReturn(this.locker);

    Locker persisted = this.service.persist(this.locker);
    assertEquals(this.locker, persisted);
  }

作为错误消息，我得到了一个针对字段锁定器的UnsatisfiedDependencyInjection。非常感谢提前！

更新

My Locker类确实没有bean，所以这导致了我的依赖性问题。现在它似乎解决了直接依赖关系，但没有传递依赖关系。例如：在我的测试中，我使用LockerService类的对象，它使用LockerRepository。这些依赖项得到解决，但LockerService也使用了类AppProperties的对象，该对象无法解析并导致NullPointerException。
