如果60s内,大量用户校验验证码时,如生成了两个相同的Code,存入Redis,验证时会失败。 以下是测试代码 public class UserProviderApplication { public static void main(String[] args) { ConfigurableApplicationContext context=SpringApplication.run(UserProviderApplication.class,args); KaptchaServiceImpl kaptchaService= (KaptchaServiceImpl) context.getBean("kaptchaServiceImpl"); Map<String,Object> map=new HashMap<String,Object>(); KaptchaCodeRequest request=new KaptchaCodeRequest(); for(int i=0;i<2000;i++){ KaptchaCodeResponse response=kaptchaService.getKaptchaCode(new KaptchaCodeRequest()); if(map.get(response.getImageCode())==null){ map.put(response.getImageCode(),response); }else{ System.out.println("60s内有重复的token生成 redis里有两份一样的code,response = " + response); request.setUuid(response.getUuid()); request.setCode(response.getCode()); KaptchaCodeResponse validateResponse=kaptchaService.validateKaptchaCode(request); System.out.println("validateResponse = " + validateResponse); } } } 结果总有一两笔是重复的: 60s内有重复的token生成 redis里有两份一样的code,response = KaptchaCodeResponse(imageCode=dktv, uuid=5e884bee-136c-4621-b58c-17f1485c28a3) 2019-10-16 16:47:16.654 INFO 908 --- [ main] c.p.user.services.KaptchaServiceImpl : 请求的redisKey=kaptcha_uuid5e884bee-136c-4621-b58c-17f1485c28a3,请求的code=000000,从redis获得的code=dktv validateResponse = KaptchaCodeResponse(imageCode=null, uuid=null) 60s内有重复的token生成 redis里有两份一样的code,response = KaptchaCodeResponse(imageCode=961m, uuid=495d00e6-a8b7-4148-9375-4940f6bed166) 2019-10-16 16:47:30.025 INFO 908 --- [ main] c.p.user.services.KaptchaServiceImpl : 请求的redisKey=kaptcha_uuid495d00e6-a8b7-4148-9375-4940f6bed166,请求的code=000000,从redis获得的code=961m validateResponse = KaptchaCodeResponse(imageCode=null, uuid=null)

如果60s内,大量用户校验验证码时,如生成了两个相同的Code,存入Redis,验证时会失败。
以下是测试代码
public class UserProviderApplication {
public static void main(String[] args) {

if(map.get(response.getImageCode())==null){
map.put(response.getImageCode(),response);
}else{
System.out.println("60s内有重复的token生成 redis里有两份一样的code,response = " + response);
