SpringBoot+redis验证阿里云短信验证码

1、这里默认你已经开通了阿里云短信服务

SendSms_短信服务_API调试-阿里云OpenAPI开发者门户

2、pom.xml引入依赖

<!-- 阿里云短信依赖-->
<dependency>
            <groupId>com.aliyun</groupId>
            <artifactId>aliyun-java-sdk-core</artifactId>
            <version>4.5.16</version>
        </dependency>
<!-- fastjson2依赖 -->
        <dependency>
            <groupId>com.alibaba.fastjson2</groupId>
            <artifactId>fastjson2</artifactId>
            <version>2.0.24</version>
        </dependency>
<!-- redisson依赖 -->
        <dependency>
            <groupId>org.redisson</groupId>
            <artifactId>redisson</artifactId>
            <version>3.13.6</version>
        </dependency>

 3、新建工具类，生成6个随机数，新建package名util，类名RandomUtil

package com.xxxx.util;

import java.text.DecimalFormat;
import java.util.*;

/**
 * 随机数生成 工具类
 */
public class RandomUtil {

    private static final DecimalFormat sixdf = new DecimalFormat("000000");

    /**
     * 生成6个随机数
     * @return
     */
    public static String getSixBitRandom() {
        return sixdf.format(random.nextInt(1000000));
    }

    
}

4.新建工具类，发送阿里云验证码，类名为：SendSmsUtil

package com.xxxx.util;

import com.alibaba.fastjson2.JSONObject;
import com.aliyuncs.CommonRequest;
import com.aliyuncs.CommonResponse;
import com.aliyuncs.DefaultAcsClient;
import com.aliyuncs.IAcsClient;
import com.aliyuncs.http.MethodType;
import com.aliyuncs.profile.DefaultProfile;
import org.apache.ibatis.reflection.ExceptionUtil;

import java.util.Map;

/**
 * 阿里云 发生 短信验证码 工具类
 * mobile 手机号码
 * param 验证码6位随机数
 */
public class SendSmsUtil {

    public static boolean sendCode(String mobile, Map<String, String> param) {
        DefaultProfile profile = DefaultProfile.getProfile("default", "您的 AccessKey ID", "必填，您的 AccessKey Secret");
        IAcsClient client = new DefaultAcsClient(profile);

        //设置相关固定的参数
        CommonRequest request = new CommonRequest();
        request.setMethod(MethodType.POST);
        request.setDomain("dysmsapi.aliyuncs.com");
        request.setVersion("2017-05-25");
        request.setAction("SendSms");

        //设置发送相关的参数
        request.putQueryParameter("PhoneNumbers", mobile); //手机号
        request.putQueryParameter("SignName","签名名称"); //申请阿里云 签名名称
        request.putQueryParameter("TemplateCode","模板code"); //申请阿里云 模板code
        request.putQueryParameter("TemplateParam", JSONObject.toJSONString(param));//验证码数据，转换json数据传递

        try {
            //最终发送
            CommonResponse response = client.getCommonResponse(request);
            boolean success = response.getHttpResponse().isSuccess();
            return success;
        } catch (Exception e) {
            e.printStackTrace();
            System.out.println(e);
            System.out.println(ExceptionUtil.unwrapThrowable(e));
            System.out.println(e.getMessage());
            return false;
        }
    }
}

5、user控制层

package com.xxxx.controller;


/**
 * user用户控制器
 */
@RestController
@Validated
public class UserController {

    @Autowired
    RedissonService redissonService;


    /**
     * 验证手机号 发生验证码
     */
    @PostMapping("/user/send")
    public ApiRestResponse sendCode(@NotBlank(message = "手机号不能为空") @Pattern(regexp = "^[1][3,4,5,6,7,8,9][0-9]{9}$", message = "手机号格式有误") String mobile) {
        //生成6位随机验证码
        String code = RandomUtil.getSixBitRandom();
        //保存验证码到redis
        Boolean isExist = redissonService.saveCodeToRedis(mobile, code);
        if(!isExist) {
            //阻止重复获取验证码
            return ApiRestResponse.error(400,"您已获取过验证码了");
        }
        //转成HashMap
        Map<String, String> param = new HashMap<>();
        param.put("code", code);
        //发送验证码
        boolean res = SendSmsUtil.sendCode(mobile, param);
        if(!res) {
            return ApiRestResponse.success("短信验证码发送失败");
        }

        return ApiRestResponse.success("短信验证码发送成功");
    }

}

6、redisson服务层 保存和验证code值

package com.xxxx.service.impl;

import com.xxxx.service.RedissonService;
import org.redisson.Redisson;
import org.redisson.api.RBucket;
import org.redisson.api.RedissonClient;
import org.springframework.stereotype.Service;

import java.util.concurrent.TimeUnit;

@Service
public class RedissonServiceImpl implements RedissonService {

    /**
     * 把手机号 和 验证码 保存到 redisson去
     * @param mobile
     * @param code
     * @return
     */
    @Override
    public Boolean saveCodeToRedis(String mobile, String code) {
        RedissonClient client = Redisson.create();
        //通过手机号 检索是否已存在
        RBucket<String> bucket = client.getBucket(mobile);
        boolean exists = bucket.isExists();
        if(!exists) {
            //如果不存在 说明是第一次放进去的 往redis set设置值
            bucket.set(code, 60, TimeUnit.SECONDS);
            //返回true 表示存储成功 在60秒内 这个值一直存在，避免用户重复获取验证码
            return true;
        }
        return false;
    }

}

package com.xxxx.service;

public interface RedissonService {

    Boolean saveCodeToRedis(String mobile, String code);

}

最后就可以使用postman等调试工具调试了。
