英文:
Apache Tomcat is showing an already made WAR file instead of the home page at localhost:8080
问题
你好，我正在尝试通过WAR文件将我的项目提交给我的指导老师。我已经创建了WAR文件，并且正在尝试检查WAR文件是否有效。但是当我运行Tomcat并在浏览器中输入 localhost:8080 时，WAR文件被部署，而不是显示首页。
启动命令提示符：
localhost:8080
我期望的结果：
ApacheTomcat Webapps 文件夹：

Hello I am trying to pass my project to my instructor through war file. I have already made the war file and I am trying to check if the war file works. But when I run the tomcat and input the localhost:8080 in the browser a WAR file is being deployed instead of the home page
Startup command prompt:
localhost:8080
What I am expecting:
ApacheTomcat Webapps Folder:

可能你是在使用你的讲师定制过的 Tomcat 版本。
通常情况下，当你从互联网上下载一个“原样”的 Tomcat 时，你应该创建一个 WAR 文件（比如 calculator.war），并将其放入 webapps 文件夹中，然后你就可以通过 localhost:8080/calculator 访问它。这是默认行为，但仍然有可能部署你定制的 WAR 文件，使其可以通过 localhost:8080 访问，就像你所描述的那样。
有几种方法可以实现这样的部署，但在你的情况下，似乎在 $CATALINA_HOME$\conf\server.xml 文件中有如下条目：
<Host name="localhost" appBase="webapps" unpackWARs="true"
autoDeploy="false" deployOnStartup="false">
<Context path="" docBase="Calculator"></Context>
....
</Host>
或者，你可能有一个位于 $CATALINA_HOME\conf\Catalina\localhost\ROOT.xml 文件中的文件，其中包含关于 Calculator WAR 文件的信息。
另一个需要检查的方向是，在你的集成开发环境中，你是否将 Calculator 项目创建成了 ROOT.war。这也是将内容部署在根路径上的一种方式。
总之，我建议你阅读这个教程，因为很有可能你正在使用这些部署方法中的其中一种。
英文:
Probably you work with a tomcat version customized by your instructor.
By default when you take a tomcat downloaded from the internet "as-is" you should create a WAR (say, calculator.war) and put into webapps folder and after that you'll be able to access it by localhost:8080/calculator. That's the default behavior, but its still possible to deploy your custom war to be accessible through localhost:8080 as you've described.
There are a couple of ways to do so, but it looks like in your case there is an entry in $CATALINA_HOME$\conf\server.xml that looks something like this:
<Host name="localhost" appBase="webapps" unpackWARs="true"
autoDeploy="false" deployOnStartup="false">
<Context path="" docBase="Calculator"></Context>
....
</Host>
Or alternatively you have $CATALINA_HOME\conf\Catalina\localhost\ROOT.xml file
that contains information about the Calculator war.
Another direction to check is that in your IDE you don't create ROOT.war out of your Calculator project. This is also a way to deploy stuff in the root context path.
All-in-all I suggest you reading This tutorial because the chances are that you somehow use one of these methods of deployment.
