Java實(shí)現(xiàn)注冊(cè)登錄與郵箱發(fā)送賬號(hào)驗(yàn)證激活功能

更新時(shí)間：2022年12月21日 09:04:02 作者：秋名山碼民

這篇文章主要介紹了Java實(shí)現(xiàn)注冊(cè)登錄與郵箱發(fā)送賬號(hào)驗(yàn)證激活功能，文中通過(guò)示例代碼介紹的非常詳細(xì)，對(duì)大家的學(xué)習(xí)或者工作具有一定的參考學(xué)習(xí)價(jià)值，需要的朋友們下面隨著小編來(lái)一起學(xué)習(xí)吧

前言

項(xiàng)目流程圖如下：

這里我們通過(guò)：

163郵箱來(lái)實(shí)現(xiàn)激活碼發(fā)送
qq郵箱來(lái)進(jìn)行接收

學(xué)習(xí)之前需要掌握的知識(shí)

springboot的基本使用方法
mysql的使用
mybatis的簡(jiǎn)單使用

項(xiàng)目環(huán)境搭建

這里我們直接使用 Spring Initializr 初始化 Spring Boot 項(xiàng)目

環(huán)境依賴(lài)選擇：

lombok簡(jiǎn)化開(kāi)發(fā)，使用注解，避免寫(xiě)重復(fù)性代碼
SpringWeb，實(shí)現(xiàn)一個(gè)前后端的數(shù)據(jù)交互（一個(gè)登錄注冊(cè)驗(yàn)證，沒(méi)必要寫(xiě)前后端分離）
MySQL
MyBatis

數(shù)據(jù)庫(kù)的搭建

注冊(cè)，登錄頁(yè)面需要的字段：

基本字段：id，email，password 常用的拓展字段：

activation_time                   // 激活失效時(shí)間
confirm_code               // 確認(rèn)代碼
is_vaild                   // 是否可用 0-不可用 1-可用
salt                       // 加密鹽
gmt_create                   // 創(chuàng)建時(shí)間
gmt_modified               // 修改時(shí)間

具體的建表語(yǔ)句

SET FOREIGN_KEY_CHECKS = 0;

前端頁(yè)面的搭建

前后端不分離下，我們前端頁(yè)面一般放到templates下面

長(zhǎng)這個(gè)樣子：

后端代碼

格式

典型的分層模型，

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; // 主鍵Id
        private String email; // 郵箱
        private String password; // 密碼 md5+鹽
       /* @DateTimeFormat(pattern = "yyyy-MM-dd HH:mm")*/
        private LocalDateTime activationTime; // 激活失效時(shí)間
        private String confirmCode; // 確認(rèn)代碼
        private Integer isVaild; // 是否可用 0-不可用 1-可用
        private String salt; // 加密鹽
/*
        @DateTimeFormat(pattern = "yyyy-MM-dd HH:mm")
*/
        private LocalDateTime gmtCreate; // 創(chuàng)建時(shí)間
/*
        @DateTimeFormat(pattern = "yyyy-MM-dd HH:mm")
*/
        private LocalDateTime gmtModified; // 修改時(shí)間
}

mapper

主要通過(guò)mybatis來(lái)寫(xiě)一些與user相關(guān)的sql語(yǔ)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 {
    /**
     * 注冊(cè)插入用戶(hù)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);
    /**
     * 根據(jù)confirm_code查詢(xún)與用戶(hù)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);
    /**
     * 根據(jù)激活碼查詢(xún)用戶(hù) 并 修改狀態(tài)值
     * */
    @Update("update user set is_vaild=1 where confirm_code = #{confirmCode}")
    int confirmUser(@Param("confirmCode") String confirmCode);
    /**
     * 根據(jù)郵箱查詢(xún)賬號(hào)
     * */
    @Select("select email,password,salt from user where email=#{email} and is_vaild=1")
    List<User> findUserByEmail(@Param("email") String email);
    /**
     * 用戶(hù)查重
     * */
    @Select("select count(*) from user where email=#{email} limit 1")
    int emailExist(@Param("email") String email);
}

Controller

與前端頁(yè)面進(jìn)行交互，負(fù)責(zé)一個(gè)登錄，注冊(cè)數(shù)據(jù)的提交和響應(yīng)

SystemController

package com.expamle.emailloginregister.controller;

/**

@Controller
public class SystemController {
    @Autowired
    private UserService userService;

    /**

    @GetMapping("/login")
    public String login(){

       return "login";
    }
    /**
     * 注冊(cè)
     * */
    @GetMapping("/registry")
    public String registry(User user){
        return "registry";
    }
}

UserController

package com.expamle.emailloginregister.controller;

    public Map<String,Object> activationAccount(String confirmCode){
        Map<String,Object> map = userService.activationAccount(confirmCode);
        return map;
    }
}

service

先寫(xiě)倆個(gè)接口，在Impl中進(jìn)行實(shí)現(xiàn)，
