        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-redis</artifactId>
        </dependency>

public void run(){

      参数四:时间类型
     */
    redisTemplate.opsForValue().set(customer.getTelephone(), activecode, 24,TimeUnit.HOURS);
