SpringBoot 获取Redis的系统时间戳

@Component
public class GetSystemTime {

    private final RedisTemplate redisTemplate;

    private static final String script_TIME = "local a=redis.call('TIME'); return (a[1]*1000000+a[2])/1000";

    public GetSystemTime(RedisTemplate redisTemplate) {
        this.redisTemplate = redisTemplate;
    }

    
    public Long currentTimeMillis() {
        final DefaultRedisscript script = new DefaultRedisscript<>(script_TIME, Long.class);
        return redisTemplate.execute(script, Collections.EMPTY_LIST);
    }
}
