我使用maven-eclipse创建了一个新的Spring MVC项目,并抛出以下错误:

(我尝试了一些来自stackoverflow的解决方案,这在我的情况下不起作用.我找不到pom.xml的一些问题.我添加了servlet-api提供的范围,并尝试了哪些也无效.)

SEVERE: Servlet /Remindem threw load() exception
java.lang.ClassCastException: org.springframework.web.servlet.DispatcherServlet 
  cannot be cast to javax.servlet.Servlet

我的pom.xml如下:

    <!-- Spring framework …

我正在尝试从命令行编译和部署一个简单的 Web 应用程序。

来自 Apache Tomcat 的 servlet-api.jar 不编译我的 java 文件，但来自 maven 中央存储库的 javax.servlet-api-4.0.1 编译成功。即便如此，当我部署应用程序并尝试在浏览器中使用它时，我还是收到了错误消息。

我在用：

• javac 11.0.8
• Apache Tomcat 10.0 (servlet-api.jar 5.0)

Java文件：

package com.example.controllers;

import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;

public class BeerSelect extends HttpServlet {
    
    public void doPost(HttpServletRequest request,
            HttpServletResponse response)
            throws IOException, ServletException {

        response.setContentType("text/html");
        PrintWriter out = response.getWriter();
        out.println("Beer Selection Advice <br>");
        String c = request.getParameter("color");
        out.println("<br>Got beer color " + c);
    }               
} 

当我尝试使用 servlet-api.jar 编译它时，我得到：

public class BeerSelect extends HttpServlet {
                                ^
  symbol: …
