我试图在Tomcat v7.0.57上部署一个webapp（名为prodPub.war），并避免从webapp创建ROOT爆炸文件夹。
我已经知道我可以将webapp重命名为ROOT，我知道以及我可以将以下配置添加到server.xml
<Host appBase="webapps" name="localhost" unpackWARs="true" autoDeploy="false" deployOnStartup="false">
<Context path="" docBase="prodPub" debug="0" reloadable="true"></Context>
</Host>
不幸的是，即使我的webapp名称是prodPub.war，我仍然只看到在Tomcat webapps文件夹中爆炸的ROOT文件夹。
在这个阶段，我最终得到了一个常用的解决方法，即在.. \ tomcat \ conf \ Catalina \ localhost文件夹中创建ROOT.xml文件，并将其内容设置为：
<Context docBase="prodPub" path="" reloadable="true" />
我在Tomcat webapps中的爆炸文件夹方面获得了我想要的东西，但是我在tomcat启动日志中发现了一些奇怪的东西

所以，我想知道这里有没有人尝试过这种方法（基于ROOT.xml文件），你对这些日志做了什么？我可以简单地忽略它们吗？
