介绍

基于SpringBoot的登录注册及找回密码有关的邮箱验证码操作

1整体思路

注册

通过输入的邮箱发送验证码，检验输入的验证码是否和后台生成的一致，若一致，将用户数据写入数据库，完成注册；

找回密码

首先校验数据库中是否存在用户名及其密码，存在时，再调用发送验证码进行比对的方式进行修改密码

2整体的结构图

3准备工程

开始QQ邮箱POP3/SMTP服务

登录QQ邮箱后，点击左上方的设置，选择账户

然后一直往下滑，看到POP3/SMTP服务，点击开启，应该会让帮定的手机号发个短信，然后会收到一个授权码，一定要好好保存，在appliction.properties配置中会用到。

创建一个SpringBoot项目工程

pom.xml中标签的全部依赖

<dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-thymeleaf</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.mybatis.spring.boot</groupId><artifactId>mybatis-spring-boot-starter</artifactId><version>2.2.0</version></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-devtools</artifactId><scope>runtime</scope><optional>true</optional></dependency><dependency><groupId>com.alibaba</groupId><artifactId>druid</artifactId><version>1.1.22</version></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-mail</artifactId></dependency><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><scope>runtime</scope></dependency><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><optional>true</optional></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency></dependencies>

配置application.properties文件

server.port=8088#邮箱配置#平台地址，这里用的是qq邮箱，使用其他邮箱请更换spring.mail.host = #spring.mail.port=587#改成自己的邮箱spring.mail.username = XXXXXXXX@#发送短信后它给你的授权码填写到这里spring.mail.password = XXXXXXXXXXXXXXXXX#这东西不用改spring.mail.properties.mail.smtp.ssl.enable=true##编码格式spring.mail.default-encoding=UTF-8#数据库相关配置spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driverspring.datasource.url=jdbc:mysql://localhost:3306/email?useSSL=true&characterEncoding=utf-8&serverTimezone=UTCspring.datasource.username=rootspring.datasource.password=123456#配置mappermybatis.mapper-locations=classpath:mapper/*.xml

创建数据库

CREATE DATABASE email;CREATE TABLE `user` (`id` int(20) NOT NULL AUTO_INCREMENT,`username` varchar(255) NOT NULL,`password` varchar(255) NOT NULL,`email` varchar(255) NOT NULL,PRIMARY KEY (`id`)) ENGINE=InnoDB AUTO_INCREMENT=6 DEFAULT CHARSET=utf8;

4全部代码类

包含义

controller包是和前端对接的
mapper包中是接口
pojo是实体类
service层是逻辑代码
vo包是前端发送数据暂时保存

执行流程

使用postman发送请求，controller中会接受，然后调用service中的逻辑代码，service会调用的mapper中接口，mapper的对应的xml实现对数据库的各种操作。

User.java

@Data@AllArgsConstructor@NoArgsConstructorpublic class User {private String username;private String password;private String email;}

UserMapper.java

@Mapper@Repositorypublic interface UserMapper {/*** 注册，插入数据* @param user*/void insertUser(User user);/*** 根据邮箱查询* @param email* @return*/User queryByEmail(String email);/*** 登录* @param user* @return*/User selectUser(User user);/*** 检验username和email是否存在* @param user* @return*/User selectUserByUsername(User user);void updateUser(User user);}

UserMapper.xml
