Spring MVC http 500错误apache

上面是我的程序的目录层次结构

我是 Spring 新手，正在学习 MVC 概念，我编写了一个程序，它将输入（名称）输入文本框并打印 Hello...'name'。以下是我的目录结构和我创建的各种文件。

web.xml

<?xml version="1.0" encoding="UTF-8"?>

    <servlet-name>hello</servlet-name>
    <url-pattern>*.ap</url-pattern> <!-- this same extension should bbe used in form action -->
  </servlet-mapping>

HelloController.java

package controller;

import java.util.HashMap;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.Controller;

import com.sun.javafx.collections.MappingChange.Map;

public class HelloController implements Controller {

    @Override
    public ModelAndView handleRequest(HttpServletRequest req, HttpServletResponse res) throws Exception {

        String name=req.getParameter("name");

        Map m= new HashMap();   // creating output object
           m.put("msg","Hello..."+name);

          ModelAndView mav=new ModelAndView("success"+m);



        return mav;
    }

}

索引.jsp

<h1> Hello World</h1>

<form action="./hello.ap">

NAME: <input type="text" name="name">
      <input type="Submit" value="Say Hello">
</form>

成功.jsp

${msg}

当我运行此代码时，index.jsp 页面运行正常，但在进一步执行时它显示错误 404。 代码有什么问题..？ 我在用日食氧气在那里面阿帕奇8.5

您定义的 servlet 名称是HelloWorld但在映射 servlet 中，是hello。 这些名称必须相同。
