感谢反馈。问题的原因见https://github.com/weibocom/motan/issues/79 我们准备通过ShutdownHook的方式fix这个问题，近期会发布一个小版本，请关注。

[yanminmin]

有相关的分支吗?

[yanminmin]

@rayzhang0603 大神

[rayzhang0603]

@yanminmin 现在还没有，尽量下周提交一个分支

[yanminmin]

多谢,非常期待.能透露下解决方案吗?

[rayzhang0603]

@yanminmin @89333367 motan0.3.1版本已提供了com.weibo.api.motan.closable.ShutDownHookListener，在web.xml中添加ShutDownHookListener即可

[89333367]

加上了，这样加的，但是还是报错，而且tomcat没有关掉，还是要kill

[rayzhang0603]

看这个异常应该是tomcat启动就没有成功吧，查一查tomcat启动失败的具体原因

[89333367]

启动是成功的，并且页面还可以通过RPC查询出结果。

[rayzhang0603]

可以确认一下info日志中是否有如下关键字Start to close global resource due to priority 如果没有表示ShutDownHookListener并没有执行 可以参考这部分代码的日志，看看静态资源回收的情况

private synchronized void closeAll() {
    Collections.sort(resourceList);
    LoggerUtil.info("Start to close global resource due to priority");
    for (closableObject resource : resourceList) {
        try {
            resource.closable.close();
        } catch (Exception e) {
            LoggerUtil.error("Failed to close " + resource.closable.getClass(), e);
        }
        LoggerUtil.info("Success to close " + resource.closable.getClass());
    }
    LoggerUtil.info("Success to close all the resource!");
    resourceList.clear();
}

[89333367]

嗯，确实没有这句话。 但是

 <listener>
        <listener-class>com.weibo.api.motan.closable.ShutDownHookListener</listener-class>
    </listener>

已经添加了，还有别的配置么？

[rayzhang0603]

不需要别的什么配置，ShutDownHookListener实现了javax.servlet.ServletContextListener，只要能够正确加载就应该可以
