1.首先导入所需的 jar 包

2.写三层

model层

package com.sm.model;public class userInfo {private String username;public String getUsername() {return username;}public void setUsername(String username) {this.username = username;}public String getUserpwd() {return userpwd;}public void setUserpwd(String userpwd) {this.userpwd = userpwd;}public String getUserid() {return userid;}public void setUserid(String userid) {this.userid = userid;}public String getUserbalace() {return userbalace;}public void setUserbalace(String userbalace) {this.userbalace = userbalace;}public String getLogintime() {return logintime;}public void setLogintime(String logintime) {this.logintime = logintime;}public String getPaymoney() {return paymoney;}public void setPaymoney(String paymoney) {this.paymoney = paymoney;}private String paymoney;private String userpwd;private String userid;private String userbalace;   //用户余额private String logintime;    //注册时间}

dao层

package com.sm.dao;import java.util.List;public interface IDaoSM<T>{/* * 添加接口 */public int addItem(T t);/* *  删除接口  */public int removeItem(Object obj);/* *  查找接口 */public T getModel(Object obj);/* * 查找接口（返回集合） */public List<T> getList(T t);}

userMapper.java

package com.sm.dao.imp;import java.util.List;import com.sm.dao.IDaoSM;import com.sm.model.userInfo;public interface userMapper extends IDaoSM<userInfo>{}

service层

package com.sm.services;import java.util.List;import org.springframework.stereotype.Controller;import com.sm.dao.imp.userMapper;import com.sm.model.userInfo;@Controllerpublic class UserInfoService {private userMapper uMapper;public userMapper getuMapper() {return uMapper;}public void setuMapper(userMapper uMapper) {this.uMapper = uMapper;}public int addItem(userInfo u){   return uMapper.addItem(u);}public List<userInfo> getList(userInfo u){return uMapper.getList(u);}/* * 注册 */public boolean register(userInfo u){if(uMapper.addItem(u)>0){return true;}else{return false;}}/* * 登录 */public userInfo login(userInfo u){List<userInfo> ulist=uMapper.getList(u);if(ulist.size()>0){return ulist.get(0);}else{return null;}}}

action层

package com.sm.action;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.servlet.ModelAndView;import com.sm.services.UserInfoService;import com.sm.model.userInfo;@Controllerpublic class userAction {       private UserInfoService userInfoService;public UserInfoService getUserInfoService() {return userInfoService;}public void setUserInfoService(UserInfoService userInfoService) {this.userInfoService = userInfoService;}@RequestMapping(value="/reg.action")public void reg(userInfo u){ if(userInfoService.register(u)){ System.out.println("操作成功"); }else{ System.out.println("操作失败"); }}}

index.jsp

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%><%String path = request.getContextPath();String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";%><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"><html>  <head>    <base href="<%=basePath%>">        <title>ssm</title>  </head>    <body>  <form id="form1" action="reg.action">       昵称：<input type="text" name="username" ><br>       密码： <input type="text" name="userpwd"><br>   id:<input type="text" name="userid"><br>      <!-- id和注册时间这里偷个懒就写死了 -->        注册时间：<input type="text" name="logintime"><br>        <input type="submit">  </form>  </body></html>

下面配置 web.xml
