提问by Nathaniel Flath
Using tomcat, how do I get a request for http://www.mydomain.comto redirect to http://www.mydomain.com/somethingelse/index.jsp? i haven't even managed to get an index.html to display from http://mydomain.com.
使用 tomcat，我如何获得http://www.mydomain.com重定向到http://www.mydomain.com/somethingelse/index.jsp的请求？我什至还没有设法从http://mydomain.com获得一个 index.html 来显示。

Name your webapp WAR “ROOT.war” or containing folder “ROOT”
将您的 webapp WAR 命名为“ROOT.war”或包含文件夹“ROOT”
回答by Viral Patel
You can do this:
If your tomcat installation is default and you have not done any changes, then the default war will be ROOT.war. Thus whenever you will call http://yourserver.example.com/, it will call the index.htmlor index.jspof your default WAR file. Make the following changes in your webapp/ROOTfolder for redirecting requests to http://yourserver.example.com/somewhere/else:
你可以这样做：如果你的 tomcat 安装是默认的并且你没有做任何更改，那么默认的 war 将是ROOT.war. 因此，无论您何时调用http://yourserver.example.com/，它都会调用您的默认 WAR 文件的index.html或index.jsp。在您的webapp/ROOT文件夹中进行以下更改以将请求重定向到http://yourserver.example.com/somewhere/else：
Open
webapp/ROOT/WEB-INF/web.xml, remove any servlet mapping with path/index.htmlor/index.jsp, and save.Remove
webapp/ROOT/index.html, if it exists.Create the file
webapp/ROOT/index.jspwith this line of content:<% response.sendRedirect("/some/where"); %>or if you want to direct to a different server,
<% response.sendRedirect("http://otherserver.example.com/some/where"); %>
打开
webapp/ROOT/WEB-INF/web.xml，删除带有路径/index.html或 的任何 servlet 映射/index.jsp，然后保存。删除
webapp/ROOT/index.html，如果存在。webapp/ROOT/index.jsp使用以下内容创建文件：<% response.sendRedirect("/some/where"); %>或者如果您想定向到不同的服务器，
<% response.sendRedirect("http://otherserver.example.com/some/where"); %>
That's it.
就是这样。

Take a look at UrlRewriteFilterwhich is essentially a java-based implementation of Apache's mod_rewrite.
看看UrlRewriteFilter，它本质上是 Apache 的 mod_rewrite 的基于 Java 的实现。
You'll need to extract it into ROOTfolder under your Tomcat's webappsfolder; you can then configure redirects to any other context within its WEB-INF/urlrewrite.xmlconfiguration file.
您需要将其解压缩到ROOTTomcatwebapps文件夹下的文件夹中；然后，您可以在其WEB-INF/urlrewrite.xml配置文件中配置重定向到任何其他上下文。

In Tomcat 8 you can also use the rewrite-valve
在 Tomcat 8 中，您还可以使用 rewrite-valve
RewriteCond %{REQUEST_URI} ^/$
RewriteRule ^/(.*)$ /somethingelse/index.jsp
To setup the rewrite-valve look here:
