Mockito：模拟对象未注入构造函数参数

Question

我有这个构造函数：

public class AuditsLoaderService {
    public AuditsLoaderService(
        BackOfficeProperties backOfficeProperties,
        FrontOfficeInterfaceService frontOfficeService,
        AuditService auditService,
        I18nResourceBundleMessageSource messageSource,
        MonitorService monitor
    ) {
      // some code
    }
}

和AuditService是：

public class AuditService {
    public AuditService(
        BackOfficeProperties backOfficeProperties,
        AuditFactory auditFactory,
        AuditDao auditDAO,
        RedisDao auditRedisDao,
        ObjectMapper objectMapper,
        I18nResourceBundleMessageSource messageSource
    ) {

进入我的测试：

@RunWith(MockitoJUnitRunner.class)
public class MalformedAuditsTest {

    @Mock
    private BackOfficeProperties backOfficeProperties;
    @Mock
    private AuditFactory auditFactory;
    @Mock
    private AuditDao auditDao;
    @Mock
    private RedisDao redisDao;
    @Mock
    private ObjectMapper objectMapper;
    @Mock
    private I18nResourceBundleMessageSource i18nResourceBundleMessageSource;
    @Mock
    private MonitorService monitorService;
    @InjectMocks
    @Spy
    private AuditService auditService;
    @InjectMocks
    private FrontOfficeInterfaceService frontOfficeService;
    @InjectMocks
    private AuditsLoaderService auditsLoaderService;

}

不过，由于auditService为null ，所以我的NulPointerException了AuditsLoaderService auditService 。

似乎没有注入。

我将其注释为：

@InjectMocks
@Spy
private AuditService auditService;

我是否应该添加更多代码/注释？

编辑

我刚刚意识到既没有注入frontOfficeService也没有注入auditSerice 。

因此， 似乎所有@InjectMocks字段都未注入其他字段

Answer 1

尝试添加：

@Mock
private ObjectMapper objectMapper;

因为您的AuditService构造函数需要它

编辑 ：通过在相应的构造函数中传递模拟来手动创建对象可能更容易
