创建一个新的 JavaWeb 项目，新建测试类 HelloServlet ，该类需要继承 HttpServlet ，所以首先需要导入 Servlet 依赖

<!--Servlet依赖-->
<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <version>3.1.0</version>
</dependency>

按照 Tomcat 自带的例子，重写 doGet 和 doPost 方法

package com.jiuxiao.servlet;

import java.io.*;
import javax.servlet.*;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

/**
 * Servlet测试
 *
 * @author WuDaoJiuXiao
 * @since 1.0.0
 */
public class HelloServlet extends HttpServlet {

    @Override
    public void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException {
        response.setContentType("text/html");
        PrintWriter out = response.getWriter();
        out.println("<html>");
        out.println("<head>");
        out.println("<title>Servlet测试</title>");
        out.println("</head>");
        out.println("<body>");
        out.println("<h1>Servlet测试</h1>");
        out.println("</body>");
        out.println("</html>");
    }

    @Override
    protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        doGet(req, resp);
    }
}
