我有一个经过验证的配置属性类。

@Data
@Configuration
@ConfigurationProperties(prefix = "notifications")
@Validated
public class NotificationConfig {
    @NotNull
    @Valid
    private NotificationMessageConfig message = new NotificationMessageConfig();
    @NotNull
    @Valid
    private SmsConfig sms = new SmsConfig();
    @NotNull
    @Valid
    private EmailConfig email = new EmailConfig();
    @NotNull
    @Valid
    private NotificationTimerConfig timer = new NotificationTimerConfig();
}

在集成测试中，我尝试自动连接类的bean。在运行时，我有一个autowiredbean，但是这个bean有空值而不是绑定配置。注意！如果我删除@validated annotation，我将拥有一个有效的bean，但是配置将不会被验证。

@Slf4j
@TestInstance(TestInstance.Lifecycle.PER_CLASS)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.DEFINED_PORT)
@RequiredArgsConstructor
public class NotificationsIT extends BaseIntegrationTest {

    @Autowired
    private Notifications notification;
    @Autowired
    private Banks banks;
    @Autowired
    private NotificationConfig notificationConfig;

   @BeforeEach
    public void init() {
        super.init();
    // notificationConfig autowired but fields have null values
        defaultNotificationConfig = clone(notificationConfig);
    }
}
