前言
项目流程图如下：
这里我们通过：
- 163邮箱来实现激活码发送
- qq邮箱来进行接收
学习之前需要掌握的知识
- springboot的基本使用方法
- mysql的使用
- mybatis的简单使用
项目环境搭建
这里我们直接使用 Spring Initializr 初始化 Spring Boot 项目
环境依赖选择：
- lombok简化开发，使用注解，避免写重复性代码
- SpringWeb，实现一个前后端的数据交互（一个登录注册验证，没必要写前后端分离）
- MySQL
- MyBatis

数据库的搭建
注册，登录页面需要的字段：
基本字段：id，email，password
常用的拓展字段：activation_time // 激活失效时间 confirm_code // 确认代码 is_vaild // 是否可用 0-不可用 1-可用 salt // 加密盐 gmt_create // 创建时间 gmt_modified // 修改时间
具体的建表语句
SET NAMES utf8mb4;
SET FOREIGN_KEY_CHECKS = 0;DROP TABLE IF EXISTS `user`;
CREATE TABLE `user` (`id` bigint NOT NULL AUTO_INCREMENT COMMENT '主键\r\n',`email` varchar(255) CHARACTER SET utf8mb3 COLLATE utf8mb3_general_ci NULL DEFAULT NULL COMMENT '邮箱',`password` varchar(255) CHARACTER SET utf8mb3 COLLATE utf8mb3_general_ci NULL DEFAULT NULL COMMENT '密码',`activation_time` timestamp NULL DEFAULT NULL COMMENT '激活失效时间',`confirm_code` varchar(255) CHARACTER SET utf8mb3 COLLATE utf8mb3_general_ci NULL DEFAULT NULL COMMENT '确认码',`is_vaild` int NULL DEFAULT NULL COMMENT '是否可用，0不可用，1可用',`salt` varchar(255) CHARACTER SET utf8mb3 COLLATE utf8mb3_general_ci NULL DEFAULT NULL COMMENT '加密盐',`gmt_create` timestamp NULL DEFAULT NULL COMMENT '创建时间',`gmt_modified` timestamp NULL DEFAULT NULL COMMENT '更新时间',PRIMARY KEY (`id`) USING BTREE,UNIQUE INDEX `email`(`email` ASC) USING BTREE

前端页面的搭建
前后端不分离下，我们前端页面一般放到templates下面

长这个样子：
后端代码
格式
典型的分层模型，
pojo
package com.expamle.emailloginregister.pojo;import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;import java.io.Serializable;
import java.time.LocalDateTime;@Data
@NoArgsConstructor
@AllArgsConstructor
public class User implements Serializable {private Integer id; // 主键Idprivate String email; // 邮箱private String password; // 密码 md5+盐/* @DateTimeFormat(pattern = "yyyy-MM-dd HH:mm")*/private LocalDateTime activationTime; // 激活失效时间private String confirmCode; // 确认代码private Integer isVaild; // 是否可用 0-不可用 1-可用private String salt; // 加密盐/*@DateTimeFormat(pattern = "yyyy-MM-dd HH:mm")
*/private LocalDateTime gmtCreate; // 创建时间/*@DateTimeFormat(pattern = "yyyy-MM-dd HH:mm")
*/private LocalDateTime gmtModified; // 修改时间
}mapper
主要通过mybatis来写一些与user相关的sql语句
package com.expamle.emailloginregister.mapper;import com.expamle.emailloginregister.pojo.User;
import org.apache.ibatis.annotations.*;import java.util.List;@Mapper
public interface UserMapper {/*** 注册插入用户信息* */@Insert("insert into user(email,password,activation_time,confirm_code,is_vaild,salt,gmt_create,gmt_modified)" +"values(#{email},#{password},#{activationTime},#{confirmCode},#{isVaild},#{salt},#{gmtCreate},#{gmtModified})")int insertUser(User user);/*** 根据confirm_code查询与用户是否已激活* confirm_code* is_vaild* */@Select("select email,activation_time from user where confirm_code = #{confirmCode} and is_vaild = 0")User findUserByConfirmCode(@Param("confirmCode") String confirmCode);/*** 根据激活码查询用户 并 修改状态值* */@Update("update user set is_vaild=1 where confirm_code = #{confirmCode}")int confirmUser(@Param("confirmCode") String confirmCode);/*** 根据邮箱查询账号* */@Select("select email,password,salt from user where email=#{email} and is_vaild=1")List<User> findUserByEmail(@Param("email") String email);/*** 用户查重* */@Select("select count(*) from user where email=#{email} limit 1")int emailExist(@Param("email") String email);
}Controller
与前端页面进行交互，负责一个登录，注册数据的提交和响应
SystemController
package com.expamle.emailloginregister.controller;import com.expamle.emailloginregister.pojo.User;
import com.expamle.emailloginregister.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;/**
*@Controller 不可使用RestControoler
*使用RestController要进行一个封装
*/
@Controller
public class SystemController {@Autowiredprivate UserService userService;/*** 登录* */@GetMapping("/login")public String login(){return "login";}/*** 注册* */@GetMapping("/registry")public String registry(User user){return "registry";}
}UserController
package com.expamle.emailloginregister.controller;import com.expamle.emailloginregister.pojo.User;
import com.expamle.emailloginregister.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;import java.util.Map;@RestController
@RequestMapping("users")
public class UserController {
@Autowiredprivate UserService userService;/*** 注册账号* */@PostMapping("register")public Map<String,Object> registery(User user){Map<String,Object> map = userService.createAccount(user);return map;}/*** 用户登录* */@PostMapping("login")public Map<String,Object> login(User user){Map<String,Object> map = userService.accountLogin(user);return map;}/*** 账号激活* 激活码附在请求后** */@GetMapping("activation")public Map<String,Object> activationAccount(String confirmCode){Map<String,Object> map = userService.activationAccount(confirmCode);return map;}
}service
先写俩个接口，在Impl中进行实现，
EmailServiceImpl
package com.expamle.emailloginregister.service;public interface EmailService {void sendEmail(String email,String activationUrl);}实现sendEmail
package com.expamle.emailloginregister.service.Impl;import com.expamle.emailloginregister.service.EmailService;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.MimeMessageHelper;
import org.springframework.stereotype.Service;
import org.thymeleaf.TemplateEngine;
import org.thymeleaf.context.Context;import javax.annotation.Resource;
import javax.mail.MessagingException;
import javax.mail.internet.MimeMessage;
import java.util.Date;/*** 发送邮件相关业务* */
@Service
public class EmailServiceImpl implements EmailService {// 引入配置文件属性@Value("${spring.mail.username}")private String sendUsername;// javamain mail依赖方法---此方法无法使用autowird注入，javaMailSender不是springboot的方法@Resourceprivate JavaMailSender javaMailSender;@Resource //同上private TemplateEngine templateEngine;public void sendEmail(String email,String activationUrl){// 创建邮件对象MimeMessage mimeMessage = javaMailSender.createMimeMessage();try {/*** MineMessagehelper---设置邮件相关内容* @Params1 邮件对象* @Params2 是否发送多封邮件* */MimeMessageHelper message = new MimeMessageHelper(mimeMessage,true);// 设置邮件主题message.setSubject("注册账号激活");// 设置邮件发送者message.setFrom(sendUsername);// 设置邮件接收者，可多个message.setTo(email);// 设置邮件抄送人/* message.setCc();*/// 设置邮件隐秘抄送人,可多个/*message.setBcc();*/// 设置邮件发送日期message.setSentDate(new Date());// 创建上下文环境--thym依赖提供方法，使用当前本地前端Context context = new Context();// 邮件中传递的链接context.setVariable("activationUrl",activationUrl);// 映射html文件String text = templateEngine.process("activation-account.html",context);// 设置邮件正文-true-是否是html模板message.setText(text,true);} catch (MessagingException e) {e.printStackTrace();}// 发送邮件javaMailSender.send(mimeMessage);}
}
UserService
package com.expamle.emailloginregister.service;import com.expamle.emailloginregister.pojo.User;
import org.springframework.transaction.annotation.Transactional;import java.util.Map;@Transactional
public interface UserService {Map<String,Object> createAccount(User user);Map<String, Object> accountLogin(User user);Map<String, Object> activationAccount(String confirmCode);
