似乎自从我们将tomcat升级到版本8后,我们就会在启动时获得上下文重新加载.然而,它似乎只发生在我们的开发环境中(带有eclipse和tomcat 8.5的Windows操作系统).我们的生产环境(带有tomcat 8.5的linux OS)没有这个问题.我发布在下面,但我没有看到任何迹象表明为什么这是从tomcat日志发生的事情.我知道这通常会改变网络应用程序目录中的某些行为,但对于我的生活,我无法弄清楚是做什么的.必须有一些方法来追踪它.
这第一块日志是完全启动的

我们可以看到有关log4j启动并且无法停止的某些线程的错误,但除此之外没有任何指示导致上下文重新加载的错误,并且关于log4j的错误仅发生因为重新加载.
如何查找上下文重新加载的原因.我们有几个项目在这个问题上受到影响,有些项目似乎比一个特定的过程或类更全球化.
还没有收到任何答案,所以我只想重申一下这个事实,我真的在寻找下一步的故障排除方法吗？一些其他日志要查看或某种方式来找出触发上下文重新加载的内容
