在tomcat中的默認網絡應用程序

Question

我一直在尋找解決方案的幾天。 我的問題是..我必須在tomcat中部署一個項目，並將其作爲默認webapp。我所做的就是複製我的war文件並將其放置在tomcat/webapps文件夾中。啓動tomcat並將端口更改爲默認值。現在我可以訪問我的申請http://localhost/myapp。我想要的是看我的申請http://localhost。我怎樣才能做到這一點？

Answer 1

刪除Tomcat/webapps/ROOT文件夾（如果有），將WAR文件重命名爲ROOT.war並重新啓動。

Answer 2

您可以將您的webapp重命名爲ROOT（tomcat的默認應用程序），或者您可以使用可以處理域名和重定向（如apache httpserver）的web服務器，並在那裏配置您的站點。

第一種方法不是很優雅，但是快速而有效。

Answer 3

我能夠通過在server.xml文件的Host下添加具有path =「」屬性的「Context」元素來完成它。

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

注意：我正在使用Tomcat 7.此外，我必須將我的webapp移動到與默認webapps文件夾不同的位置。我還刪除了由tomcat提供的默認webapps。但是這個解決方案即使不刪除它們也可以工

這裏是我的server.xml的內容以供參考。希望這可以幫助。

在webapps/ROOT下面創建index.html。

<html> 

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

<body> 
</body> 

</html>
