在tomcat中重新部署应用程序时Spring bean未被破坏

Question

我有一个webapp，它正在Tomcat9上部署。作为部署的一部分，我们只需将war放到webapps目录中，tomcat负责war的重新部署。但是有时我们会在日志中看到一些错误，主要是一些spring bean的destroy方法没有被调用：

31-Aug-2017 21:41:35.292 INFO [ContainerBackgroundProcessor[StandardEngine[Catalina]]] org.apache.catalina.startup.HostConfig.undeploy Undeploying context [/globalsearch]

<bean id="GlobalSearchEventLoadMessageProcessing"
    class="xxx.GlobalSearchEventLoadMessageProcessing"
    init-method="initialize" destroy-method="cleanUp">
</bean>

PS：我不能停止和启动服务器部署过程。

查看错误，调用了该方法：

WARN : org.springframework.beans.factory.support.DisposableBeanAdapter - Invocation of destroy method 'cleanUp' failed on bean with name 'GlobalSearchEventLoadMessageProcessing': java.lang.IllegalStateException: java.io.FileNotFoundException: /opt/tomcat/9.0.0.M19/webapps/globalsearch/WEB-INF/lib/commons-collections-3.2.1.jar (No such file or directory)

但它失败了，因为很可能是由于争用条件--您试图从已经从容器中移除的jar文件中运行一些代码。在cleanup方法中可以避免使用外部库吗？
