这几天我一直在寻找解决方案。 我的问题是..我必须在 tomcat 中部署一个项目并将其设置为默认 webapp。我所做的是复制我的战争文件并将其放在 tomcat/webapps 文件夹中。启动tomcat并将端口更改为默认值。现在我可以在http://localhost/myapp 访问我的应用程序。我想要在http://localhost 看到我的应用程序。我怎样才能做到这一点？
【问题讨论】：
标签： web-applications tomcat default
在 webapps/ROOT 下创建 index.html。
<html>
<head>
<meta http-equiv="refresh" content=0;URL="http://localhost/myapp">
</head>
<body>
</body>
</html>
【讨论】：
urllib2 或 httplib2 或 requests 库，则不会。
我可以通过在 server.xml 文件的 Host 下添加带有 path="" 属性的 "Context" 元素来做到这一点。
<Context path="" docBase="/usr/local/tomcat/mywebapps/myapplication">
<WatchedResource>WEB-INF/web.xml</WatchedResource>
</Context>
注意：我使用的是 Tomcat 7。此外，我必须将我的 webapp 移动到与默认 webapps 文件夹不同的位置。我还删除了 tomcat 提供的默认 webapps。但即使不删除它们，此解决方案也能正常工作。
这里是我的 server.xml 的内容供参考。希望这会有所帮助。

【讨论】：
您可以将您的 webapp 重命名为 ROOT（tomcat 的默认应用程序），或者您可以使用可以处理域名和重定向的 web 服务器（如 apache httpserver），并在那里配置您的站点。
第一种方法不是很优雅，但是快速高效。
【讨论】：
删除Tomcat/webapps/ROOT 文件夹（如果有），将您的WAR 文件重命名为ROOT.war 并重新启动。
