篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Web.xml警告“对Web内容中不存在的主文件名引用”相关的知识，希望对你有一定的参考价值。
题：
- 我想在web.xml中将servlet“main”设置为欢迎文件，但它显示警告“web内容中不存在的主文件名引用”
- 浏览器无法访问CSS文件，但可以访问属于同一父目录“assests”的图像
- 我想知道这两个问题是否相关以及如何解决它们
我已经引用的内容：
- how-to-include-external-css-file-in-jsp
- 类似的SO问题：qazxsw poi，qazxsw poi，qazxsw poi
结果：
veb.hml

main Servlet.Java
http://localhost:8080/SampleApplication
MainView.jsp
http://localhost:8080/SampleApplication/main
目录结构
<?xml version="1.0" encoding="UTF-8"?>
<web-app id="WebApp_ID" version="3.1"
xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd">
<display-name>SampleApplication</display-name>
<welcome-file-list>
<welcome-file>main</welcome-file>
</welcome-file-list>
</web-app>
谢谢！
您应该在@WebServlet(name = "main", urlPatterns = { "/main" })
public class MainServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
public MainServlet() {
super();
}
/**
* Forwards to the main page.
*/
@Override
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
RequestDispatcher dispatcher
= this.getServletContext().getRequestDispatcher("/WEB-INF/views/MainView.jsp");
dispatcher.forward(request, response);
}
@Override
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
//Additional Logic
}
元素中定义欢迎文件列表。所以请尝试将其更改为<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">

并将jsp文件移动到
<welcome-file>。
