servlet项目启动报404怎么解决

Question

使用的是注释,metadata-complete="true"，下面是web.xml

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

web

<welcome-file>index.html</welcome-file>

<welcome-file>index.htm</welcome-file>

<welcome-file>index.jsp</welcome-file>

<welcome-file>default.html</welcome-file>

<welcome-file>default.htm</welcome-file>

<welcome-file>default.jsp</welcome-file>

写个打印语句也报404

package com.it66.session;

import java.io.IOException;

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 SessionServlet

  */

@WebServlet("/SessionServlet")

public class SessionServlet extends HttpServlet {

private static final long serialVersionUID = 1L;

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

System.out.println("SessionServlet");

}}

求大佬帮解决

为什么没有实现 doGet或者doPost方法呢？
