为什么使用eclipse总是出现404

为什么使用eclipse总是出现404

index里面

<%@ page language="java" contentType="text/html; charset=utf-8"

pageEncoding="utf-8"%>

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<html>

<head>

<title>Insert title here</title>

</head>

<body>

</form>

</body>

</html>

Helloservlet里面的代码如下，没有配置web.xml因为已经有了注解

package servlet;

import java.io.IOException;

import java.io.PrintWriter;

import javax.servlet.ServletException;

import javax.servlet.annotation.WebServlet;

import javax.servlet.http.HttpServlet;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

/**

* Servlet implementation class Helloservlet

@WebServlet("/Helloservlet")

public class Helloservlet extends HttpServlet {

private static final long serialVersionUID = 1L;

/**

* Default constructor.

public Helloservlet() {

// TODO Auto-generated constructor stub

}

/**

* @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

// TODO Auto-generated method stub

doPost(request, response);

response.getWriter().append("Served at: ").append(request.getContextPath());

System.out.println("很好");

PrintWriter out=response.getWriter();

response.setContentType("text/html;charset=utf-8");

out.println("<strong>xixi</strong>");

}

/**

* @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

// TODO Auto-generated method stub

doGet(request, response);

System.out.println("很好");

PrintWriter out=response.getWriter();

response.setContentType("text/html;charset=utf-8");

out.println("<strong>xixi</strong>");

}

但是一直出现以下问题，已经一个消失了都没有解决成功，求大神来解答
