Eclipse中的Tomcat-HTTP Status 404請求的資源不可用
[英]Tomcat in Eclipse - HTTP Status 404 requested resource is not available
問題描述
我快要瘋了。
我在這里關注教程
我有這個index.html文件
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>
<h1>Hello World</h1>
</body>
</html>
還有web.xml文件
這兩個文件都位於WebContent文件夾中
我可以毫無問題地運行Tomcat，並且
http://localhost:8080/
工作正常，但是當我運行應用程序或轉到
http://localhost:8080/ServletTutorial/
要么
http://localhost:8080/ServletTutorial/index.html
它給出404錯誤，請求的資源不可用。
我已經將Tomcat配置為使用Tomcat安裝。
我要哭了...我被困在這里兩天了:(

2 個解決方案

您的應用未部署到Tomcat，因為沒有日志記錄，例如
Deployment of web application directory ... ServletTutorial
當您將eclipse配置為使用tomcat安裝時，請嘗試檢查tomcat的webapp文件夾-應用程序文件應包含ServletTutorial目錄。 根據教程檢查其完整性。 如果不存在，請刪除該應用程序，然后再次添加它，或者使用“服務器”窗口中的“清理”菜單選項進行完全重新發布。
我建議不要把tomcat的安裝目錄弄亂，而是將其配置為使用工作區元數據文件夾。 然后，只有您的應用程序才能與我們的管理器，示例和其他不必要的應用程序一起啟動，從而縮短了開發周期。

如今（java ee 2019-09），web.xml文件位於Tomcat文件夾中，檢查其默認是否具有相同的文件名：
