使用springboot 2.0时，如何从RedisTemplate获取Jedis客户案例？以下内容不起作用

Question

String result = (String) redisTemplate.execute((RedisCallback<String>) connection -> {
        JedisCommands jedisCommands = (JedisCommands) connection.getNativeConnection();
        return jedisCommands.set(lockKey, requestId, SET_IF_NOT_EXIST, SET_WITH_EXPIRE_TIME,expireTime);
    });
