Java Web App - 尝试运行 JSP 文件 (IntelliJ) 时出现错误 404

问题描述 投票：0回答：1

当我尝试运行 JSP 文件（右键单击文件名并在 IntelliJ 中运行）时，我得到 404

我的JSP代码：

`<%@ page contentType="text/html; charset=ISO-8859-1"
         pageEncoding="ISO-8859-1"%>
<!DOCTYPE html>
<html>
<head>
    <meta charset="ISO-8859-1">
    <link rel="stylesheet" href="sites.css" type="text/css" />
    <title>Add</title>
    <link rel="stylesheet" href="button.css" type="text/css" />
</head>
<body>
<div align="center">
    <h1>Add Company</h1><br>
</form>
    <br><br>
    <p>fill the form below to add company:</p>
    <form action="add" method="post">
        <table style="width:80%">
            <tr>
                <td>Name</td>
                <td><input type="text" name="name" /></td>
            <tr>
                <td>Register Number</td>
                <td><input type="text" name="register_number" /></td>
        </table><br>
        <table>
            <tr>
                <td>
                    <input type="submit" value="Submit" class="buttonbtn"/></td></tr></table>
    </form>
    <br><br>
    <table>
        <tr><td><a href="/miniCRM/src/main/webapp/WEB-INF/main.html" class=buttonbtn>Main Page</a></td></tr></table>
</div>
</body>
</html>`

Servlet：

`package com.example.minicrm.controller;

        try {

        } catch (ClassNotFoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        RequestDispatcher dispatcher = request.getRequestDispatcher("/WEB-INF/AddCompany.jsp");
        dispatcher.forward(request, response);

添加依赖项：

 `<dependency>
            <groupId>org.apache.tomcat.embed</groupId>
            <artifactId>tomcat-embed-core</artifactId>
            <version>9.0.84</version>

        <dependency>
            <groupId>org.apache.tomcat.embed</groupId>
            <artifactId>tomcat-embed-jasper</artifactId>
            <scope>provided</scope>
        </dependency>`

没有帮助。

我正在尝试在本地主机上运行它。无法使用 mvn clean-spring boot run 运行它（没有这样的选项）。

我将感谢所有建议。

WEB-INF 的内容不能由客户端直接请求。那是你的类文件、属性文件以及谁知道还有什么东西存放的地方。将文件移到那里之外。
