基于session注册JAva篇springboot

springboot3全家桶，数据库：redis，mysql

背景环境：邮箱验证码，验证注册

流程：先通过邮箱验证，发送验证码，将获取到的session和验证码，存入redis里（发送邮箱）

在pop添加

<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>

@Resource

StringRedisTemplate template;有了上面的框架就可以直接调用

server服务层

发送邮件impl实现层代码

    @Overridepublic String sendValidateEmail(String email, String session) {//数据搬运工，将key搬运来String key = "email:" + session + ":" + email;//处理数据,深加工，if (Boolean.TRUE.equals(template.hasKey(key))) {Long expire = Optional.ofNullable(template.getExpire(key, TimeUnit.SECONDS)).orElse(0L);if (expire > 120)return "请稍后再试！";}Random random = new Random();int code = random.nextInt(899999) + 10000;SimpleMailMessage simpleMailMessage = new SimpleMailMessage();simpleMailMessage.setFrom("yanxin_ru@163.com");simpleMailMessage.setTo(email);simpleMailMessage.setSubject("您的安全验证邮件");simpleMailMessage.setText("验证码:" + code);try {mailSender.send(simpleMailMessage);template.opsForValue().set(key, String.valueOf(code), 3, TimeUnit.MINUTES);return "发送成功";} catch (MailException e) {e.printStackTrace();return "发送失败";}}

注册实现

  @Overridepublic String addValidateUser(String username, String password, String email, String code, String session) {String key = "email:" + session + ":" + email;if (Boolean.TRUE.equals(template.hasKey(key))) {int i = mapping.userByAdmitOREmail(email).getId();if (i >= 3){return "邮箱注册上限!（3）";}String s = template.opsForValue().get(key);if (s == null) return "验证码失效,请重新获得验证码";if (Objects.equals(s, code)) {String encode = new BCryptPasswordEncoder().encode(password);if (mapping.addUser(username, encode, email) > 0) {return null;} else {return "系统问题，请联系管理员";}} else {return "验证码错误，请重新输入验证码";}} else return "请先获取验证码，感谢配合！";}

每次成功发送邮箱，就会运行这条

template.opsForValue().set(key, String.valueOf(code), 3, TimeUnit.MINUTES);

在redis存储一条key+email+session

注册功能会失败的情况下目前所知道的有三种!!!

在说问题前，最重要的是这条代码Boolean.TRUE.equals(template.hasKey(key))

如果我们邮箱发送成功了，那么redis里是能查到数据的
