spark处理过程如下:
1.读取,ssc自带的receiver,解析(valueSplit方法 处理成kv格式)
2.过滤filterRegex,类似sql中的where条件放弃一些不需要的数据,比如只需要买单的数据而不要下单数据
3.转换,getPlatform、getFormatDate,类似case when
4.创建了一个class命名为result,重写了toString方法。该class存放从kafka中处理后的所有需要的数据字段。
5.写入MySQL,insertIntoMySQL,方法在每个partition中调用
另外代码中使用了getOrCreate以便恢复,利用了计数器简单统计了一下有效记录数
代码如下:
