## **一.导入初始化的maven项目** ##

导入的方法可以参考下面链接：

[如何在eclipse中导入maven项目 ？在eclipse中导入maven项目的教程-天极下载][eclipse_maven_ _eclipse_maven_-]

[如何用Eclipse导入一个已经存在的Maven项目 - 爱码爱生活][Eclipse_Maven_ -]

[Eclipse在运行 Maven项目build时出现No compiler is provided in this environment的处理\_康冕峰的博客-CSDN博客][Eclipse_ Maven_build_No compiler is provided in this environment_-CSDN]

导入后并启动初始化的maven项目的静态页面

## 二.创建数据库 ##

## 三.代码开发 ##

### 3.1**注册登录功能的开发** ###

**学习目标**

1.能够完成项目注册功能

2.能够完成邮箱登录功能

**学习指南**

1.  注册功能的表单校验
2.  注册功能的验证码校验
3.  注册功能的邮箱激活
4.  登录功能的实现

#### 3.1.1注册功能分析 ####

![watermark_type_d3F5LXplbmhlaQ_shadow_50_text_Q1NETiBA5peg5bC955qE5rKJ6buY_size_20_color_FFFFFF_t_70_g_se_x_16][]

#### 1.前端页面功能实现 ####

\*使用js完成表单校验

\*使用ajax完成表单提交

\*注册成功后，跳转的页面success.html

**1.1表单校验功能**

![watermark_type_d3F5LXplbmhlaQ_shadow_50_text_Q1NETiBA5peg5bC955qE5rKJ6buY_size_15_color_FFFFFF_t_70_g_se_x_16][]

①用户名：单词字符，长度8-20位（当然这里也可以设计成校验是否中英文名字）

②密码：单词字符，长度8-20位

③email：邮件格式

④姓名：非空

⑤手机号：手机号格式

⑥出生日期：非空

⑦验证码：非空

**1.2代码的编写**

表单各种校验js代码可以参考：[JS常用的表单验证（数字、长度,汉字，邮箱，手机号，身份证等）\_无尽的沉默的博客-CSDN博客\_js表单验证身份证][JS_-CSDN_js]

ajax是用来验证表单的正确性

**①用户名校验**

用正则表达式校验账号密码是否符合规范
    function checkUsername() {
       //1.获取用户名值
       var username = $("#username").val();
       //2.定义正则
       var reg_username = /^\w{8,20}$/;
       
       //3.判断，给出提示信息
        var flag = reg_username.test(username);
        if(flag){
            //用户名合法
                     $("#username").css("border","");
       }else{
            //用户名非法,加一个红色边框
          $("#username").css("border","1px solid red");
       }
        
       return flag;
    }

**②密码校验**

//校验密码
    		   function checkPassword() {
    			 //1.获取用户名值
    			   var password = $("#password").val();
    			   //2.定义正则
    			   var reg_password = /^\w{8,20}$/;
    			   
    			   //3.判断，给出提示信息
    			    var flag = reg_password.test(password);
    			    if(flag){
    			        //用户名合法
    			                 $("#password").css("border","");
    			   }else{
    			        //用户名非法,加一个红色边框
    			      $("#password").css("border","3px solid red");
    			   }
    			    
    			   return flag;
    			}

**③电子邮箱检验**

//校验电子邮件
    		   function checkEmail() {
    			   //1.获取用户名值
    			   var email = $("#email").val();
    			   //2.定义正则
    			   //对电子邮件的验证
    			   var reg_email = /^([a-zA-Z0-9]+[_|\_|\.]?)*[a-zA-Z0-9]+@([a-zA-Z0-9]+[_|\_|\.]?)*[a-zA-Z0-9]+\.[a-zA-Z]{2,3}$/;
    			   
    			   //3.判断，给出提示信息
    			   var flag = reg_email.test(email);
    			   if(flag){
    			       //用户名合法
    			       $("#email").css("border","");
    			   }else{
    			       //用户名非法,加一个红色边框
    			       $("#email").css("border","3px solid red");
    			   }
    			   return flag;
    			}
    		  //检验姓名（中文）
    		  function checkName() {
    			//1.获取姓名值
    			var name=$("#name").val();
    			//2.定义正则
    			//对姓名进行验证
    			var reg_name =/^[\u0391-\uFFE5]+$/;
    			//3.判断，给出提示信息
    			var flag = reg_name.test(name);
    			if(flag){
    			       //用户名合法
    			       $("#name").css("border","");
    			}else{
    			       //用户名非法,加一个红色边框
    			       $("#name").css("border","3px solid red");
    			}
    			return flag;
    		   }
    		   //检验手机号
    			function checkTelephone() {
    				//1.获取姓名值
    				var telephone=$("#telephone").val();
    				//2.定义正则
    				//对姓名进行验证
    				var reg_telephone =/^(((13[0-9]{1})|(15[0-9]{1})|(18[0-9]{1}))+\d{8})$/;;
    				//3.判断，给出提示信息
    				var flag = reg_telephone.test(telephone);
    				if(flag&&(telephone.length==11)){
    				       //手机号合法
    				       $("#telephone").css("border","");
    				}else{
    				       //手机号非法,加一个红色边框
    				       $("#telephone").css("border","3px solid red");
    				}
    				return flag;
    			}
    		//检验出生日期
    		  function checkBirthday() {
    			//1.获取出生日期
    			var birthday=$("#birthday").val();
    			var date1=birthday.replace(/-/g,"/");//替换字符，变成标准格式(检验格式为：'2009-12-10')
    			// var obj_value=obj.replace("-","/");//替换字符，变成标准格式(检验格式为：'2010-12-10 11:12')
    			var date1=new Date(Date.parse(date1));
    			print(date1)
    			var date2=new Date();//取今天的日期
    			//3.判断，给出提示信息
    			if(date1>date2){
    				//日期非法,加一个红色边框
    			    $("#birthday").css("border","3px solid red");
    			    return false;
    			}
    			else{
    				$("#birthday").css("border","");
    				return true;
    			}
    		}

Ajax校验

//ajax校验
    		   $(function() {
    			$("#registerForm").submit(function() {
    				return checkUsername()&&checkPassword();
    			});
    			//当某一个组件失去焦点时，调用对应的校验方法
    			$("#username").blur(checkUsername);
    			$("#password").blur(checkPassword);
    			$("#email").blur(checkEmail);
    			$("#name").blur(checkName);
    			$("#telephone").blur(checkTelephone);
    			$("#birthday").blur(checkBirthday);
    		});

#### 2.后端代码的编写 ####

首先编写web层的控制器RegistUserServlet，它用来接收前端请求数据信息，然后交给service层处理

package cn.itcast.travel.web.servlet;
    
    import java.io.IOException;
    import java.lang.reflect.InvocationTargetException;
    import java.util.Map;
    
    import javax.servlet.ServletException;
    import javax.servlet.annotation.WebServlet;
    import javax.servlet.http.HttpServlet;
    import javax.servlet.http.HttpServletRequest;
    import javax.servlet.http.HttpServletResponse;
    
    import org.apache.commons.beanutils.BeanUtils;
    
    import com.fasterxml.jackson.databind.ObjectMapper;
    
    import cn.itcast.travel.dao.impl.UserDaoImpl;
    import cn.itcast.travel.domain.ResultInfo;
    import cn.itcast.travel.domain.User;
    import cn.itcast.travel.service.UserService;
    import cn.itcast.travel.service.impl.UserServiceImpl;
    
    /**
     * Servlet implementation class RegistUserServlet
     */
    @WebServlet("/registUserServlet")
    public class RegistUserServlet extends HttpServlet {
    	private static final long serialVersionUID = 1L;
           
        /**
         * @see HttpServlet#HttpServlet()
         */
    	protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    		// TODO Auto-generated method stub
    		this.doPost(request, response);
    	}
    
    	/**
    	 * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
    	 */
    	protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    		//1.获取前端的数据
    		Map<String, String[]> map=request.getParameterMap();
    		
    		//2.封装对象
    		User user=new User();
            try {
    			BeanUtils.populate(user, map);  //将map中的字典封装成user
    		} catch (IllegalAccessException | InvocationTargetException e) {
    			// TODO Auto-generated catch block
    			e.printStackTrace();
    		}
            System.out.println(user);
            
    		//3.调用service层的函数来完成注册
            UserService userService=new UserServiceImpl();
            boolean flag=userService.regist(user);
            
            ResultInfo info=new ResultInfo();  //返回的结果封装info对象
    		//4.响应结果
            if(flag) {  //注册成功
            	info.setFlag(true);	
            }
            else {  //注册失败
            	info.setErrorMsg("注册失败！");
            	info.setFlag(false);
            	System.out.println("注册失败");
            }
            //将info对象序列化成json
            ObjectMapper oMapper=new ObjectMapper();
            String json=oMapper.writeValueAsString(info);
            
            //将json字符串回写到客户端
            //设置content-type
            response.setContentType("application/json;charset=utf-8");
            response.getWriter().write(json);
            
    	}
    
    }

service层中userservice接口和它的实现类userserviceImpl编写

package cn.itcast.travel.service;
    
    import cn.itcast.travel.domain.User;
    
    public interface UserService {
    	//注册用户
    	public boolean regist(User user);
    }

package cn.itcast.travel.service.impl;
    
    import cn.itcast.travel.dao.UserDao;
    import cn.itcast.travel.dao.impl.UserDaoImpl;
    import cn.itcast.travel.domain.User;
    import cn.itcast.travel.service.UserService;
    
    public class UserServiceImpl implements UserService {
        //注册用户
    	@Override
    	public boolean regist(User user) {
    		// 通过用户名来查询用户信息
    		UserDao uDao=new UserDaoImpl();
    		User user2=uDao.findByUsername(user.getUsername());
    		if(user2!=null) {
    			//说明已经注册了信息,用户名注册失败
    			return false;
    		}
    		//没有注册，保存用户的信息
    		uDao.save(user);
    		return true;
    	}
    
    }

DAO层中userdao接口和它的实现类userdaoImpl编写

package cn.itcast.travel.dao;
    
    import cn.itcast.travel.domain.User;
    
    public interface UserDao {
    	  //根据用户名来查询用户信息
          public User findByUsername(String username);
          //用户信息保存
          public void save(User user);
          
    }

package cn.itcast.travel.dao.impl;
    
    import org.springframework.dao.DataAccessException;
    import org.springframework.jdbc.core.BeanPropertyRowMapper;
    import org.springframework.jdbc.core.JdbcTemplate;
    
    import cn.itcast.travel.util.JDBCUtils;
    import cn.itcast.travel.dao.UserDao;
    import cn.itcast.travel.domain.User;
    
    
    public class UserDaoImpl implements UserDao {
    	//操作数据库的对象
    	private JdbcTemplate jdbcTemplate=new JdbcTemplate(JDBCUtils.getDataSource());
    	@Override
    	public User findByUsername(String username) {
    		//根据用户名来查询用户信息
    		User user=null;
    		try {//这个trycatch是为了防止jdbctemplate查询时没查到用户，封装用户会出异常，不是返回null 而设置的
    			// 1.编写sql语句
    			String sql="select* from tab_user where username = ?";
    			//2.执行sql语句
    			user = jdbcTemplate.queryForObject(sql, new BeanPropertyRowMapper<User>(User.class),username);
    		} catch (DataAccessException e) {
    		}
    		return user;
    	}
    
    	@Override
    	public void save(User user) {
    		// 1.定义sql
    		String sql="insert into tab_user(username,password,name,birthday,sex,telephone,email) values(?,?,?,?,?,?,?)";
    		//2.执行sql语句
    		jdbcTemplate.update(sql,user.getUsername(),
    				                user.getPassword(),
    				                user.getName(),
    				                user.getBirthday(),
    				                user.getSex(),
    				                user.getTelephone(),
    				                user.getEmail()
    				           );
    		
    	}
         
    }

至此注册这个功能原理基本完成

其他：

JDBCUtils类中编写了获得连接池对象的方法，这里不阐述

jdbc连接数据库的jar包以及js相关的jar包，这里省略了

![watermark_type_d3F5LXplbmhlaQ_shadow_50_text_Q1NETiBA5peg5bC955qE5rKJ6buY_size_18_color_FFFFFF_t_70_g_se_x_16][]

#### 3.后台验证码和前台对返回数据的处理 ####

我们只需要在web层的控制器RegistUserServlet中编写接收来自客户端的验证码值和接收来自checkCodeServlet中session域值，然后两者进行比较，如果不相同，则设置结果对象信息为验证码错误，并将结果对象序列化为json,返回给客户端显示
