# 第三步： #

添加一个这个选项，否则创建工程会很缓慢

archetypeCatalog=internal

# 第四步： #

等待其创建完成之后补齐目录结构

# 第五步: #

引入servlet依赖

<dependency>
          <groupId>javax.servlet</groupId>
          <artifactId>javax.servlet-api</artifactId>
          <version>4.0.1</version>
          <scope>provided</scope>
        </dependency>

# 第六步： #

创建servlet并写好访问信息

@WebServlet("/MyServlet")
    public class MyServlet extends HttpServlet {
        @Override
        protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    
        }
    
        @Override
        protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
            System.out.println("来到了servlet====hello");
        }
    }

# 第七步： #

替换web.xml为4.0版

<?xml version="1.0" encoding="UTF-8"?>
    <web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
             version="4.0">
    
    </web-app>

启动服务器访问地址即可
