redis的储存都是key-value的格式

一般会将spark统计完的结果按时间来作为文件的名字(也就是key值),统计结果是整个分类好的数据,转换成json格式,

---注意,调用JedisUtils工具的类需要实现Serializable系列化接口;

  List<Tuple2<String, Integer>> collect_ = stringIntegerJavaPairRDD1.collect();
        //用写的工具类将时间格式转换再存入Tuple2里
       // List<Tuple2<String, Integer>> collect =DateOut.getTuple2(collect_);
        if (CollectionUtils.isNotEmpty(collect)) {
            //每个小时的页面访问量 把 集合持久化到redis、mysql 中
       //将集合里的Tuple2的String值(一般都是取得时间--年/月/日/几点/几分/几秒)这种格式,
       //我们截取取年月日作为key值,也就是保存的文件名字 String key
= collect.get(0)._1.substring(0, collect.get(0)._1().length() - 3); System.out.println(key);        //下面就是写入redis数据库 JedisUtils.set(key, JSON.toString(collect), 0); } else { logger.info("分析的日志为空"); }      //关闭主入口 javaSparkContext.close();
