Web applications tomcat中的默认web应用程序

这几天我一直在寻找解决办法。

---

我的问题是..我必须在tomcat中部署一个项目，并将其作为默认的webapp。我所做的是复制我的war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端口。现在我可以在访问我的应用程序。我想在查看我的应用程序。我该怎么做

删除

Tomcat/webapps/ROOT

文件夹（如果有），将您的WAR文件重命名为

ROOT.WAR

，然后重新启动。

您可以将您的webapp重命名为ROOT（Tomcat的默认应用程序），也可以使用能够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，但是快速有效。

我可以通过在server.xml文件的Host下添加带有path=”“属性的“Context”元素来实现

            <Context path="" docBase="/usr/local/tomcat/mywebapps/myapplication">
                <WatchedResource>WEB-INF/web.xml</WatchedResource>
            </Context>

WEB-INF/WEB.xml

注意：我使用的是Tomcat7。此外，我还必须将我的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。但这种解决方案即使不删除它们也能起作用

以下是my server.xml的内容供参考。希望这有帮助

WEB-INF/WEB.xml

在webapps/ROOT上创建index.html，如下所示

<html>

<head>
    <meta http-equiv="refresh" content=0;URL="http://localhost/myapp">
</head>

<body>
</body>

</html>

我做了，但是我得到了apache tomcat主页。然后你修改或访问了错误的tomcat实例。您使用的是IDE还是什么？是的，我使用netbeans IDE部署项目。您应该在项目属性中将上下文名称设置为空字符串或/。由于我不使用Netbeans，因此无法详细说明如何/在何处使用。不管怎样，如果将IDE排除在考虑范围之外，答案是有效的，并且您完全按照问题中提到的那样做：复制WAR并将其放置在tomcat/webapps中。是的，我这样做了，我不再使用netbeans。我关闭了netbeans，只使用了war文件。您是否介意添加一些信息，说明为什么您认为这是解决此问题的最佳方案？（而不是服务器端重定向）。我不认为这是一个答案，在我投票表决之前，我想听听你的推理。这只适用于浏览器（即加载和解析HTML的客户端）。例如，如果您使用的是Python

urllib2

或

httplib2

或

请求

库，则不是这样。如上所述，这只是一个网页，而不是真正的重定向。这种方法不会在webapps下部署两次应用程序吗？from:“使用自动部署时，由XML上下文文件定义的docBase应位于appBase目录之外。如果不是这样，则可能会遇到部署web应用程序的困难，或者可能会部署两次应用程序。”
