@Override
public void execute(Tuple input, BasicOutputCollector collector) {
    byte[] binary = input.getBinary(0);
    String line = new String(binary);
    String[] fields = line.split("\t");

    if(fields == null || fields.length < 10) {
        return;
    }

    // 获取ip和mid
    String ip = fields[1];
    String mid = fields[2];

    // 根据ip获取其所属地（省份）
    String province = null;
    if (ip != null) {
        Jedis jedis = JedisUtil.getJedis();
        province = jedis.hget("ip_info_en", ip);
        // 需要释放jedis的资源，否则会报can not get resource from the pool
        JedisUtil.returnJedis(jedis);
    }

    // 发送数据到下一个bolt，只发送实现业务功能需要的province和mid
    collector.emit(new Values(province, mid));
