说明
- 只是模拟给手机发送短信验证码,并且进行校验
- 真正能够给手机发送验证码短信还需要结合第三方,如阿里云、讯飞等
需求
- 发送手机号,返回验证码(6位随机数字)
- 每个手机号一天只能发送10次(为了测试方便,可以改成3次),每天0点重置次数
- 当天获取次数达到上限,提示“当天验证码获取次数已达上限,请明天再次使用”
- 每个验证码有效期为5分钟,获取验证码提示“【XX系统】您的手机验证码为:XXXXXX,有效期5分钟,此功能每天最多获取XX条,请勿向任何人出示,以免账号被盗”
- 5分钟内再次获取验证码提示“已有可用验证码,XX分XX秒内依然有效”
- 发送手机号和验证码,对手机号和验证码进行校验,返回验证结果
- 提示:“验证通过”或“验证失败,请确认手机号或验证码”

2.Controller
@RestController
public class PhoneController {
@Resource
private PhoneService phoneService;
@RequestMapping("/send")
public String send(String phone) {
return phoneService.send(phone);
}
@RequestMapping("/check")
public String check(String phone,String code) {
return phoneService.check(phone,code);
}
}
3.service
3.1常量设定
private static final int MAX_TIME_OUT = 5;
private static final String MAX_PHONE_COUNT= "3";
private static final String PHONE_COUNT_SUFFIX=":COUNT";
private static final String PHONE_CODE_SUFFIX=":CODE";
3.2判断获取次数
if(RedisStringUtil.get(codeKey)==null &&
"3".equals(RedisStringUtil.get(countKey))){
return "当天验证码获取次数已达上限,请明天再次使用";
}
3.3判断验证码剩余时间
long exTime = RedisKeyUtil.getExpire(codeKey);
if(exTime>0){
return "已有可用验证码," + (exTime / 60) + "分 " + (exTime % 60) +
" 秒内依然有效";
}
3.4获取验证码
String.valueOf(new Random().nextInt(900000) + 100000);
3.5保存验证码,设置有效期,累加获取次数
String code = getCode();
RedisStringUtil.setEx(codeKey,code,MAX_TIME_OUT, TimeUnit.MINUTES);
RedisStringUtil.incrBy(countKey,1);
3.6校验手机号与验证码
String codeKey = phone + PHONE_CODE_SUFFIX;
if(code!=null && code.equals(RedisStringUtil.get(codeKey))){
return "验证成功";
}
return "验证失败,请确认手机号或验证码";
service层完整代码
@Service
public class PhoneService {
private static final int MAX_TIME_OUT = 5;
private static final String MAX_PHONE_COUNT= "3";
private static final String PHONE_COUNT_SUFFIX=":COUNT";
private static final String PHONE_CODE_SUFFIX=":CODE";
public String send(String phone) {
String countKey = phone + PHONE_COUNT_SUFFIX; //次数
String codeKey = phone + PHONE_CODE_SUFFIX; //验证码
if(RedisStringUtil.get(codeKey)==null &&
"3".equals(RedisStringUtil.get(countKey))){
return "当天验证码获取次数已达上限,请明天再次使用";
}
long exTime = RedisKeyUtil.getExpire(codeKey);
if(exTime>0){
return "已有可用验证码," + (exTime / 60) + "分 " + (exTime % 60) +
" 秒内依然有效";
}
String code = getCode();
RedisStringUtil.setEx(codeKey,code,MAX_TIME_OUT, TimeUnit.MINUTES);
RedisStringUtil.incrBy(countKey,1);
return "【地笼系统】您的手机验证码为:" + code
+ ",有效期5分钟,此功能每天最多获取" + MAX_PHONE_COUNT +
"条,请勿向任何人出示,以免账号被盗";
}
public String check(String phone, String code) {
String codeKey = phone + PHONE_CODE_SUFFIX;
if(code!=null && code.equals(RedisStringUtil.get(codeKey))){
return "验证成功";
}
return "验证失败,请确认手机号或验证码";
}
private String getCode(){
return String.valueOf(new Random().nextInt(900000) + 100000);
}
}
4.设置定时任务,每天0点清除所有短信获取次数
@Configuration
public class TaskConfig {
@Scheduled(cron = "10 18 * * * ?")
public void clearPhoneCount(){
System.out.println("-----------------");
RedisKeyUtil.delete(RedisKeyUtil.keys("*:COUNT"));
}
}
5.启动类上添加开启定时任务
@EnableScheduling
public class RedisdemoApplication {
public static void main(String[] args) {
SpringApplication.run(RedisdemoApplication.class, args);
}
}
