在带有@RefreshScope的类中使用@PostConstruct时出现IllegalArgumentException

Question

当我在一个使用@PostConstruct的类中使用@RefreshScope时，我的Spring应用程序无法启动。这是我的代码：

@Log4j2
@Component
@RefreshScope
public class MeetingEvent implements EventType {
private UserProperties userProperties;
private UserEvent meetingEvent;
private ObjectMapper objectMapper;
private UserEventRepository userEventRepository;
private UserEventType userEventType;

public MeetingEvent(UserProperties userProperties, ObjectMapper objectMapper, UserEventRepository userEventRepository) {
    this.userProperties = userProperties;
    this.objectMapper = objectMapper;
    this.userEventRepository = userEventRepository;
}

@PostConstruct
public void postConstruct() {
    this.meetingEvent = userEventRepository.findOne((long) 1);
    this.userEventType = UserEventType.MEETING_EVENT;
}

当我启动我的应用程序时，这是我得到的错误：

我发现了我的问题。这是我的Spring-cloud依赖关系的结果，以前是“Edgeware”。我降级回“达尔斯顿”，解决了这个问题。
