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-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" metadata-complete="true" version="3.1">

  <absolute-ordering/>

  <display-name>web</display-name>

  <welcome-file-list>

    <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>

  </welcome-file-list>

</web-app>

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");

}}
