一、说明

电商网站中已经有越来越多的用户来自移动端，相比起传统浏览器的登录方式，手机APP成为了更多用户访问电商网站的首选。对于电商企业来说，一般会通过各种不同的渠道对自己的APP进行市场推广，而这些渠道的统计数据（比如，不同网站上广告链接的点击量、APP下载量）就成了市场营销的重要商业指标。

二、思路

统计 不同渠道的不同用户行为

三、数据准备

封装数据的JavaBean类

package com.lyh.flink06;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;@Data
@AllArgsConstructor
@NoArgsConstructor
public class MarketingUserBehavior {private Long userId;private String behavior;private String channel;private Long timestamp;
}

四、代码

package com.lyh.flink06;import org.apache.flink.api.common.functions.MapFunction;
import org.apache.flink.api.java.tuple.Tuple2;
import org.apache.flink.streaming.api.environment.StreamExecutionEnvironment;
import org.apache.flink.streaming.api.functions.source.SourceFunction;import java.util.Random;public class Project_AppAnalysis_By_Chanel {public static void main(String[] args) throws Exception {StreamExecutionEnvironment env = StreamExecutionEnvironment.getExecutionEnvironment();env.setParallelism(2);env.addSource(new AppSource()).map(new MapFunction<MarketingUserBehavior, Tuple2<String,Long>>() {@Overridepublic Tuple2<String, Long> map(MarketingUserBehavior value) throws Exception {return Tuple2.of(value.getBehavior() + "_" + value.getChannel(),1L);}}).keyBy(0).sum(1).print();env.execute();}public static class AppSource implements SourceFunction<MarketingUserBehavior> {@Overridepublic void run(SourceContext<MarketingUserBehavior> ctx) throws Exception {Random random = new Random();String[] behaviors = {"update", "install", "uninstall", "update"};String[] chanels ={"HW","VIVO","XIAOMI","OPPO"};while (true){Long userId = (long)(random.nextInt(2000) + 1);String behavior = behaviors[random.nextInt(behaviors.length)];String chanel = chanels[random.nextInt(chanels.length)];Long timstampes = System.currentTimeMillis();ctx.collect(new MarketingUserBehavior(userId,behavior,chanel,timstampes));Thread.sleep(200);}}@Overridepublic void cancel() {}}}

五、运行结果
