StringRedisTemplate使用总结之批量删除前缀key

       Set<String> keys = redisTemplate.keys("u:" + "*");
        Set<String> keys1 = redisTemplate.keys("U:INFO:" + "*");  
        if (StringUtil.isNotNull(keys)) {
            redisTemplate.delete(keys);
        }
     
        if (StringUtil.isNotNull(keys1)) {
            redisTemplate.delete(keys1);
        }
