在上一篇博客里，我们使用Maven构建了一个Web项目，我们在这里写一个简单的Servlet，测试一下。
1.在src/main/java下，新建一个Servlet
package com.deppon.text01.action;import java.io.IOException;import javax.servlet.ServletException;import javax.servlet.http.HttpServlet;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;public class UserServlet extends HttpServlet { private static final long serialVersionUID = 1L; protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { doPost(request , response); } protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { request.setCharacterEncoding("UTF-8"); response.setContentType("text/html;charset=utf-8"); String action = request.getParameter("action"); if("login_input".equals(action)) { request.getRequestDispatcher("login.jsp").forward(request , response); } else if("login".equals(action)) { String name = request.getParameter("name"); String password = request.getParameter("password"); System.out.println("name->" + name + ",password->" + password); } }} 2. 修改web.xml
UserServlet com.deppon.text01.action.UserServlet UserServlet /user 3. 新建JSP
index.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> Hello Maven 大家好！
去登录 login.jsp <%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>登录界面
4. 测试
项目结构如下图所示：
其实，构建完成之后，开发的话，应该和平时开发Web项目是一样的。

之前忘记说明pom文件了，需要添加依赖的：
pom.xml
