启动类
@SpringBootApplication
@MapperScan("com.example.mapper")//将mapper路径下自动注册映射器接口为spring Bean
public class SpringBootDemo1Application {public static void main(String[] args) {SpringApplication.run(SpringBootDemo1Application.class,args);}
}
测试类
@SpringBootTest
@RunWith(SpringRunner.class)
class SpringBootTestApplicationTests {}
idea建表

编写yml文件

qq邮箱设置
点击第二列的账号：开启服务，发送邮件，记下授权码 ok !
登陆注册代码
编写持久层(Dao)
@Data
@AllArgsConstructor
@NoArgsConstructor
@TableName(value = "user")
public class User {@TableId(value = "id",type = IdType.AUTO)private Integer id;@TableField(value = "email")private String email;@TableField(value = "password") // 密码，使用md5+盐加密private String password;@TableField(value = "salt")private String salt; // 盐@TableField(value = "confirm_code") // 确认码private String confirmCode;@TableField(value = "activation_time") // 激活失效时间private LocalDateTime activationTime;@TableField(value = "is_valid") // 账号状态private Byte isValid;}注册代码
业务层
public interface UserService extends IService<User> {// 创建账号Map<String,Object> createAccount(User user);// 创建账号过程中，用于激活账号的确认码，没有激活不可以登录账号Map<String, Object> activation(String confirmCode);// 将用户信息录入数据库int insertUser(User user);// 通过确认码查找用户,不用担心确认码重复User selectUserByConfirmCode(String confirmCode);// 通过邮箱激活账号int updateUserByConfirmCode(String confirmCode);// 通过邮箱名查找用户（如果没有进行注册查重，那么将这个修改成List<User>有多个用户报异常）User selectUserByEmail(String email);
}
业务实现类

因为用的是thymeleaf写的所以目录结构如下（记得写在templates中）
