Web.xml警告“对Web内容中不存在的主文件名引用”

问题描述 投票：0回答：1

题：

  1. 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”
  2. 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
  3. 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：

  1. how-to-include-external-css-file-in-jsp
  2. 类似的SO问题：qazxsw poi，qazxsw poi，qazxsw poi

结果：

  • 1取主页作为主页
  • 2也取得主页
  • 但在这两种情况下，都不会加载任何CSS文件。
  • 我已经独立测试了支架中的前端并且工作正常。

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"> <title>Ship Short Dated Products</title> <!-- ---------------------- BOOTSTRAP AND CUSTOM STYLESHEETS ----------------------- --> <link rel="stylesheet" type="text/css" href="<c:url value="http://fonts.googleapis.com/css?family=Roboto:400,100,300,500" />"> <link rel="stylesheet" type="text/css" href="<c:url value="/assets/bootstrap-3.3.7-dist/css/bootstrap.min.css" />"> <link rel="stylesheet" type="text/css" href="<c:url value="/assets/font-awesome/css/font-awesome.min.css" />"> <link rel="stylesheet" type="text/css" href="<c:url value="/assets/css/form-elements.css" />"> <link rel="stylesheet" type="text/css" href="<c:url value="/assets/css/main-layout.css" />"> <!-- --------------------------- JQUERY AND BOOTSTRAP PLUGINS ------------------------------- --------------------------- Please maintain the order for libs ------------------------- --> <script src="<c:url value="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js" />"></script> <script src="<c:url value="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js" />"></script> <!--[if lt IE 9]> <script src="https://oss.maxcdn.com/html5shiv/3.7.2/html5shiv.min.js"></script> <script src="https://oss.maxcdn.com/respond/1.4.2/respond.min.js"></script> <![endif]--> </head> <body> <!-- -------------------------------- IMAGE CONTENT -------------------------------- --> <img class="img-responsive" src="assests/images/HMSGradient.jpg"> <!-- IMAGE CONTENT End --> </body> </html> 并将jsp文件移动到enter image description here。此外，您不需要<welcome-file>。
