接着上一篇继续说,上一篇主要的还是连接邮箱和发信测试,这次主要就是对于接口制作和测试了
首先,按照先一篇的接着写
SpringBoot 验证码生成+SMTP邮箱服务配置 – Karos (wzl1.top)
POM-Maven依赖引入 Spring Data Redis以及Pool连接池
具体为什么我不用Jedis,主要是线程安全问题
<!--redis-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>
<!--pool连接池-->
<dependency>
<groupId>org.apache.commons</groupId>
<artifactId>commons-pool2</artifactId>
</dependency>
application.yml配置(用的properties的配置这里也有)
#yml配置
spring:
redis:
auth: 123456
host: 127.0.0.1
port: 6379
lettuce:
pool:
max-active: 8
max-idle: 8
max-wait: 100
min-idle: 0
#properties配置
spring.redis.auth=123456
spring.redis.host=127.0.0.1
spring.redis.lettuce.pool.max-active=8
spring.redis.lettuce.pool.max-idle=8
spring.redis.lettuce.pool.max-wait=100
spring.redis.lettuce.pool.min-idle=0
spring.redis.port=6379
编写验证码查找、删除、匹配服务层(虽然是服务层,但我仍然划在工具类中)
如果我们通过邮箱发送验证码,那么肯定要给验证码设置一个有效期,同一个邮箱在同一时间片段只能过有一个短信验证码,如果在同一时间内重复申请没有,但是没有用,为了避免计算开销,我们可以直接返回(当然,你也可以重新生成)。
一般验证码我们实在注册账号的时候用,我们在注册的时候也会判断用户等级(这个一般是交给前端做,但是后端也可以做做【花里胡哨】)
============重点来了=============
我们存储验证码采用redis,使用SpringDataRedis框架
我们在用户安全类中写个 RedisTmplate 类,并且自动装配,redistemplate的具体用法自查,不做解释,这里就只是实现

控制层编写–邮箱服务
在后面的项目开发中,我们邮箱服务不一定只用来发送验证码,也有可能拿来做一些消息预警推送或者一些信息推送
所以这里我们做一个控制层
/**

es.send();
return new JsonRes(HttpCode.Success,"success");
}

boolean b = usu.delCheckCode(user.getEmail());
return new JsonRes(HttpCode.Accepted,"Regesiter OK!",user).AllData();
}
}
代码测试:
写完了,我们Run一下
是不是感觉有那味儿了?
