SpringBoot|Spring-Data-Redis 验证码短信存储服务

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

/**

package com.karos.td.Controller;

import com.karos.td.Common.http.HttpCode;
import com.karos.td.Util.EmailUtil.EmailSend;
import com.karos.td.Util.JsonUtil.JsonRes;
import com.karos.td.Util.SafetyUtil.UserSafetyUtil;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;

@RestController//Controller+RepouseBody
@RequestMapping("/api/mail")
public class MailController {
    @Autowired
    private EmailSend es;
    @Autowired
    private UserSafetyUtil usu;
    //@PathVariable /xxxx地址内引入var
    //@RequestParam ?add=xxxx
    @PostMapping
    public JsonRes send(@RequestParam("add") String mailAddress){
        String code = usu.findUsercode(mailAddress);
        if(code!=null){
            es.setMessage(mailAddress,"【OK服务】验证码接收","您好,这是您的验证码,请在5分钟内使用,谢谢:【"+code+"】");
            return new JsonRes(HttpCode.Success,"success");
        }
        code=usu.MakeCodetoDb(mailAddress);
        es.setMessage(mailAddress,"【OK服务】验证码接收","您好,这是您的验证码,请在5分钟内使用,谢谢:【"+code+"】");
        es.send();
        return new JsonRes(HttpCode.Success,"success");
    }
}

        if (usi.isExsitUserByMail(user.getEmail())==true){
            return new JsonRes(HttpCode.Success,"The E-mail Addres is Used,Please Change the E-mail!",null).toString();

写完了,我们Run一下

是不是感觉有那味儿了?
