基于Spark的电商用户行为分析系统的设计与实现

项目架构

Flume–>Kafka–>Spark Streaming–>Mysql–>FineReport 10

数据可视化使用第三方软件FineReport支持

1. 数据采集：利用Java线程模拟行为数据写入被监控的文件

模拟电商网站用户行为数据（也可与阿里云天池开源数据集：真实的淘宝或天猫用户行为数据）

user_id	用户ID,整数类型，序列化后的用户ID
item_id 商品ID,整数类型，序列化后的商品ID
category_id 商品类目ID,整数类型，序列化后的商品所属类目ID
behavior_type 行为类型,字符串,枚举类型,包括('pv','buy', 'cart','fav')
ddate 行为发生的时间

flume实时监控数据文件，并将新增的用户行为数据采集传输给Kafka

启动flume：

flume-ng agent -c ./softwares/flume/conf/ -f ./flume2kafka.conf -n a1

flume2kafka.conf

a1.sources = r1
a1.sinks = k1
a1.channels = c1

# Describe/configure the source
# 这里其实是监控Linux命令的source，该命令是监控文件并将实时变化的内容输出
a1.sources.r1.type = exec
a1.sources.r1.command = tail -F /home/admin/bigdata.log

# 设置kafka接收器 
a1.sinks.k1.type = org.apache.flume.sink.kafka.KafkaSink
# 设置kafka的broker地址和端口号
a1.sinks.k1.brokerList=172.17.33.37:9092
# 设置Kafka的topic
a1.sinks.k1.topic=henry
# 设置序列化的方式
a1.sinks.k1.serializer.class=kafka.serializer.StringEncoder

# use a channel which buffers events in memory
a1.channels.c1.type=memory
a1.channels.c1.capacity = 100000
a1.channels.c1.transactionCapacity = 1000

# Bind the source and sink to the channel
a1.sources.r1.channels=c1
a1.sinks.k1.channel=c1

Kafka接收数据：将flume传输过来的数据放入消息队列，等待spark streaming 消费
启动zookeeper

zkServer.sh start

启动Kafka（-deamon后台启动）

kafka-server-start.sh -daemon ./softwares/kafka/config/server.properties

创建topic（3个分区，1个副本，topic名为henry）

kafka-topics.sh --create --zookeeper 172.17.33.37:2181 --replication-factor 1 --partitions 3 --topic henry

#查看所有topic
kafka-topics.sh --list --zookeeper 172.17.33.37:2181 

#定义一个Kafka生产者端口
kafka-console-producer.sh --broker-list 172.17.33.37:9092 --topic henry

#定义一个Kafka消费者端口
kafka-console-consumer.sh --bootstrap-server 172.17.33.37:9092 --topic henry

数据采集部分已准备完成，这里没有进行数据清洗而是将全量的上游数据传输至数据处理模块，统一处理

2. 数据处理

spark streaming 程序为实时等待流，从Kafka指定的topic中消费数据

UserBehavior.scala

/**
  * spark streaming实时处理kafka端的数据并持久化到MySQL
  *
  * @author huangxuan
  * @date 2021.03.19
  */
object UserBehavior {
  def main(args: Array[String]): Unit = {
    Logger.getLogger("org.apache.spark").setLevel(Level.WARN)
    System.setProperty("spark.serializer","org.apache.spark.serializer.KryoSerializer")
    //sc
    val sc = new SparkConf().setAppName("To MySql").setMaster("local[5]")
    //ssc  每5秒一个批次
    val ssc = new StreamingContext(sc,Seconds(5))

    //从Kafka中读取数据
    val topics = "henry"  //topic name
    val numThreads = 3 //每个topic的分区数
    val topicMap = topics.split(" ").map((_,numThreads.toInt)).toMap
    val kafkaStream = KafkaUtils.createStream(
      ssc, // spark streaming 上下文对象
      "172.17.33.37:2181", //zookeeper 集群
      "test1",   //topic 所在组
      topicMap
    )

    //获取一个连接对象
    val conn = ConnectionPool.getConnection
    val stmt = conn.createStatement

    //spark streaming 消费数据
    val lines = kafkaStream.map(_._2).flatMap(_.split("\n"))
    lines.foreachRDD(line=>{
      //将kafka的数据以行为单位转换成字符串集合
      // (1,1,pv),(1,2,pv)
      val datas:Array[String] = line.collect()
      datas.foreach(x=>{
        val parms = x.split(",")
        val sql = "insert into user_behavior values("+parms(0)+","+parms(1)+",\'"+parms(2)+"\');"
        stmt.executeUpdate(sql)
        println(sql)
      })
    })
    ConnectionPool.returnConnection(conn)

    ssc.start
    //实时等待流
    ssc.awaitTermination
  }
}

jar包上传至服务器并执行spark streaming程序

spark-submit --class "saprkStreaming.KafkaWordCounter" --master local[2] Spark_Study-1.0-SNAPSHOT.jar

3.数据分析

本次分析所使用的模型和体系

电商分析通常从四个方面展开，即流程效率分析、流量/用户分析、商品分析、产品分析，通过流程效率拆解追踪问题产生环节，通过用户粘性、价值、满意度分析来进行用户分层及流失预警，通过商品生命周期及关联分析来划分商品等级，通过产品分析提升用户浏览-购买过程体验；

本项目通过常用的电商数据分析指标，采用AARRR漏斗模型拆解用户进入APP后的每一步行为；并使用RFM模型，对用户价值进行评价，找到最有价值的用户群，针对这部分用户进行差异化营销。文章来源地址https://www.toymoban.com/news/detail-441053.html

用户:
    年龄：不同年龄段的购物需求
    地区：不同地区的购物需求
    性别：不同性别的购物需求
    以及其他组合分析
商品：
    类型：
    价格：

4. 数据库设计

采用MySQL 8.0.23 作为spark streaming的下游数据持久层
