我快要失去理智了

我在这里学习教程

我有这个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>

工作正常，但当我运行应用程序或转到

http://localhost:8080/ServletTutorial/

或

它给出404错误，请求的资源不可用

我已经将Tomcat配置为使用Tomcat安装

我快要哭了。。。我被困在这里两天了：(

您的应用程序未部署到Tomcat，因为没有日志记录，例如

Deployment of web application directory ... ServletTutorial

当您将eclipse配置为使用tomcat安装时，请尝试检查tomcat的webapp文件夹-应用程序文件中应该有ServletTutorial目录。根据教程检查其完整性。如果不存在，请删除应用程序并再次添加，或者使用Servers窗口中的Clean菜单选项完全重新发布

我建议不要弄乱tomcat安装目录，而是将其配置为使用工作区元数据文件夹。这样，只有我们的管理器、示例和其他不必要的应用程序才能启动您的应用程序，从而缩短您的开发周期。

如今（java ee 2019-09）xml文件位于Tomcat文件夹中，请检查默认情况下是否具有相同的文件名：

两个文件都在WebContent文件夹中-实际上web.xml必须在WebContent/web-INF文件夹中。我正在尝试输入xml文件代码，但它不允许我0_oDidn没有得到最后的注释。是否有任何错误？我已经制作了web.xml代码的图片，因为这里说代码没有正确缩进（WTF）。也尝试过将xml文件移动到Web Inf文件夹中，但仍然没有成功。你可以发布你的tomcat日志吗？它可以在控制台选项卡上找到。我已经删除了服务器并创建了一个新的服务器，现在它可以工作了！所以我下面的教程是错误的，因为你说Web.xml文件必须在Web-Inf文件夹中，而不是在带有index.html的Web内容中，对吗？此外，即使应用程序工作时，我也签入了Tomcat/webapps，并且没有Servlet教程目录。这是为什么？这是因为新服务器配置为使用.metadata文件夹，而不是webapps目录。你可以在

.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps

附近找到你的应用程序。我没有每次我添加一个新的java类时，我必须删除并重新创建服务器，否则我会得到资源找不到错误。这是为什么？无论如何，这个问题可以避免，而不必一直删除并重新创建服务器？
