Java 使用@Scheduled spring注释时出现异常（找不到类[org.springframework.scheduling.annotation.AsyncAnnotationBeanPostProcessor]）

我已使用

@scheduled

批注创建了一个计划作业。 看起来是这样的：

package example.tools.rr; 

public class RequestProcessorJob {
    private RequestService requestService;
    ...
    @Scheduled(fixedRate = 10000)
    public void process() {
         ...
    }

    public RequestService getRequestService() { return requestService; }

    public void setRequestService(RequestService requestService) { this.requestService = requestService; }

}

我已经把它放在一个bundle a中，所以我可以在其他bundle中使用这个类。我在bundle B中导入了它。B的blueprint.xml如下所示：

package example.tools.rr; 

public class RequestProcessorJob {
    private RequestService requestService;
    ...
    @Scheduled(fixedRate = 10000)
    public void process() {
         ...
    }

    public RequestService getRequestService() { return requestService; }

    public void setRequestService(RequestService requestService) { this.requestService = requestService; }

}

如果我添加了一个空类，该类在bundle B中只有一个

@Scheduled

注释，那么一切正常，并且RequestProcessorJob被正确地调度（不使用空类，但它不会发生错误）

我尝试将模块A包含在

pom.xml

中的B中，作为

提供的
以及
编译
，结果是相同的

有一个reduntant类使其工作听起来并不是一个真正的解决方案。你对此有什么想法吗？这是一个bug，或者可能是某种奇怪的工作方式吗？
好的，我只是缺少pom.xml中org.springframework.scheduling.annotation一节中的org.springframework.scheduling.annotation。毕竟很明显，但春天的行为在这里仍然很奇怪
