*  **用户行为日志概述：**

*  用户行为日志：

用户每次访问网站时所有的行为数据（访问、浏览、搜索、点击...）用户行为轨迹、流量日志。

*  日志数据内容：

1.  访问的系统属性： 操作系统、浏览器等等
2.  访问特征：点击的url、从哪个url跳转过来的(referer)、页面上的停留时间等
3.  访问信息：session\_id、访问ip(访问城市)等

*  日志举例：

格式：访问时间 访问内容网址 从哪个浏览器跳转 session\_id 访问ip

拿到数据之后：

一般的日志处理方式，我们是需要进行分区的，

按照日志中的访问时间进行相应的分区，比如：d,h,m5(每5分钟一个分区)

输入：访问时间、访问URL、耗费的流量、访问IP地址信息

输出：URL、cmsType(video/article)、cmsId(编号)、流量、ip、城市信息、访问时间、天

Imooc网主站日志介绍：

1.  访问时间
2.  访问url
3.  访问过程耗费的流量

数据清洗：
    
    对于时间格式的数据处理：
    
    [10/Nov/2016:00:01:02 +0800]
    
    对于以上的时间的处理方式：
    
    import java.text.SimpleDateFormat
    import java.util.Locale
    import java.util.Date
    
    /**
     * 日期时间解析工具类
      * 10/Nov/2016:00:01:02 +0800
     */
    object DateUtils {
    
    
        //输入文件日期格式
        //10/Nov/2016:00:01:02 +0800
        val YYYYMMDDHHMM_TIME_FORMAT = new SimpleDateFormat("dd/MMM/yyyy:HH:mm:ss Z",Locale.ENGLISH)
        //目标文件日期格式
        val TARGET_FORMAT = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss")
    
        /**
          * 获取时间：yyyy-MM-dd HH:mm:ss
          */
        def parse(time:String)={
          TARGET_FORMAT.format(new Date(getTime(time)))
        }
    
        /**
          * 获取输入日志的时间
          * 日期格式
          *[10/Nov/2016:00:01:02 +0800]
          *
          */
        def getTime(time:String) ={
    
          try{
            YYYYMMDDHHMM_TIME_FORMAT.parse(time.substring(time.indexOf("[")+1,time.lastIndexOf("]"))).getTime
          }catch {
            case e:Exception =>{
              0l
            }
          }
        }
    
        def main(args: Array[String]){
          println(parse("[10/Nov/2016:00:01:02 +0800]"))
        }
    
    }

**转换结果如下：**

我们使用上面 的日期转换格式会发现我们得出的结果可能有问题列如像下面这样的数据：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQxNDc5NDY0_size_16_color_FFFFFF_t_70 2][]

所以对于日期格式的转换工具类还需要改进：
    
    日期转换格式二：
    
    package com
    
    import java.text.SimpleDateFormat
    import java.util.Locale
    import java.util.Date
    
    import org.apache.commons.lang3.time.FastDateFormat
    
    /**
     * 日期时间解析工具类
      * 10/Nov/2016:00:01:02 +0800
     */
    object DateUtils {
    
    
        //输入文件日期格式
        //10/Nov/2016:00:01:02 +0800
        val YYYYMMDDHHMM_TIME_FORMAT = FastDateFormat.getInstance("dd/MMM/yyyy:HH:mm:ss Z",Locale.ENGLISH)
        //目标文件日期格式
        val TARGET_FORMAT = FastDateFormat.getInstance("yyyy-MM-dd HH:mm:ss")
    
        /**
          * 获取时间：yyyy-MM-dd HH:mm:ss
          */
        def parse(time:String)={
          TARGET_FORMAT.format(new Date(getTime(time)))
        }
    
        /**
          * 获取输入日志的时间
          * 日期格式
          *[10/Nov/2016:00:01:02 +0800]
          *
          */
        def getTime(time:String) ={
                //注意需要转换为Long类型的数据
          try{
            YYYYMMDDHHMM_TIME_FORMAT.parse(time.substring(time.indexOf("[")+1,time.lastIndexOf("]"))).getTime
          }catch {
            case e:Exception =>{//如果输入的时间异常：那么就是直接转换为0
              0l
            }
          }
        }
    
        def main(args: Array[String]){
          println(parse("[10/Nov/2016:00:01:02 +0800]"))
        }
    
    }

然后观看数据就没有之前出现的情况了。原因：SimpleDateFormat 线程不安全。
    
    整体得到时间，url，流量，ip地址、数据代码如下：
    
    package com
    
    import org.apache.spark.sql.SparkSession
    
    /**
     * 第一步清洗：抽取出我们想要的指定列的数据
     */
    object SparkStatFormat {
    
      def main(args: Array[String]) {
    
        val spark = SparkSession.builder().appName("SparkStatFormatJob").master("local[2]").getOrCreate()
        //读取数据
        val access = spark.sparkContext.textFile("D:\\BigDataTest\\data\\access.20161111.log")
        //打印出前面100条数据
        //    access.take(100).foreach(println)
        //按照空格进行数据分割
        access.map(line =>{
          val splits = line.split(" ")
          val ip = splits(0)//第一个为ip地址
          //根据断点调试可以看到时间在第几个split的数组当中
          /**
          * 原始日志的第三个和第四个字段拼接起来就是完整的访问时间
            * (183.162.52.7,[10/Nov/2016:00:01:02 +0800]) ==》yyyy-MM-dd HH:mm:ss
            * 这个时间需要时间解析
          **/
          val time = splits(3)+" "+splits(4)
          //拿取url,经过反复调试可以观察到split(11)为url
          //把不必要的引号替换为空的
          val url = splits(11).replaceAll("\"","")
          //流量
          val traffic = splits(9)
    
          //利用元组的形式存放
          //用写的时间转换的工具类来转换时间
    //      (ip,DateUtils.parse(time),url,traffic)
          DateUtils.parse(time)+"\t"+url+"\t"+traffic+"\t"+ip
        }).saveAsTextFile("D:\\BigDataTest\\data\\output")
    
    
        spark.stop()
      }
    
    }

写入磁盘得到的数据：因为太多了，所以自动分块写的。

拿到数据之后：

一般的日志处理方式，我们是需要进行分区的，

按照日志中的访问时间进行相应的分区，比如：d,h,m5(每5分钟一个分区)

        try {
          val splits = log.split("\t")
          val url = splits(1)
          val traffic = splits(2).toLong
          val ip = splits(3)
          val domain = "http://www.imooc.com/"
          val cms = url.substring(url.indexOf(domain)+domain.length)
          var cmsTypedId = cms.split("/")
          var cmsType = ""
          var cmsId = 0l
    
          if (cmsTypedId.length>1){
            cmsType = cmsTypedId(0)
            cmsId = cmsTypedId(1).toLong
          }

        }catch {
          case e: Exception=>Row(0)
        }
      }
    }

输入：访问时间、访问URL、耗费的流量、访问IP地址信息

输出：URL、cmsType(video/article)、cmsId(编号)、流量、ip、城市信息、访问时间、天

***Ip地址转换******使用github上已有的开源项目***

1）git clone https://github.com/wzhe06/ipdatabase.git

2）编译下载的项目：mvn clean package -DskipTests

3）安装jar包到自己的maven仓库

mvn install:install-file-Dfile=D:\\BigDataTest\\test\\ipdatabase-master\\target\\ipdatabase-1.0-SNAPSHOT.jar -DgroupId=com.ggstar -DartifactId=ipdatabase -Dversion=1.0 -Dpackaging=jar

java.io.FileNotFoundException:

    object MysqlUtils {
      def getConnection()={
        DriverManager.getConnection("jdbc:mysql://localhost:3306/imooc_project?user=root&password=root")
    
    
      }
      /**
        * 释放数据库连接等资源
        * @param connection
        * @param pstmt
        */
      def release(connection: Connection, pstmt: PreparedStatement): Unit = {
        try {
          if (pstmt != null) {
            pstmt.close()
          }
        } catch {
          case e: Exception => e.printStackTrace()
        } finally {
          if (connection != null) {
            connection.close()
          }
        }
      }
      def main(args: Array[String]): Unit = {
        println(getConnection())
      }
    }

然后写一个实体类的代码：

**package** log  
  
*/\*\**  
*  \* 每天课程访问次数实体类*  
*  \** ***@param day***  
***  ****\** ***@param cmsId***  
***  ****\** ***@param times***  
***  ****\*/*  
**case class** DayVideoAccessStat (day:String,cmsId:Long,times:Long)\{  
  
\}

一个StatDao层就是我需要的插入数据库的逻辑层：

package log
    
    import java.sql.{Connection, PreparedStatement}
    
    import scala.collection.mutable.ListBuffer
    
    /**
      * 各个维度统计的Dao操作
      */
    object StatDao {
      /**
        * 批量保存到DayVideoAccessStat数据库中
        *
        */
    
      /**
        * 批量保存DayVideoAccessStat到数据库
        */
      def insertDayVideoAccessTopN(list: ListBuffer[DayVideoAccessStat]): Unit = {
    
        var connection: Connection = null
        var pstmt: PreparedStatement = null
    
        try {
          connection = MysqlUtils.getConnection()
    
          connection.setAutoCommit(false) //设置手动提交
    
          val sql = "insert into day_video_access_topn_stat(day,cms_id,times) values (?,?,?) "
          pstmt = connection.prepareStatement(sql)
    
          for (ele <- list) {
            pstmt.setString(1, ele.day)
            pstmt.setLong(2, ele.cmsId)
            pstmt.setLong(3, ele.times)
    
            pstmt.addBatch()
          }
    
          pstmt.executeBatch() // 执行批量处理
          connection.commit() //手工提交
        } catch {
          case e: Exception => e.printStackTrace()
        } finally {
          MysqlUtils.release(connection,pstmt)
        }
      }
    }

统计topN的课程数插入到数据库中的代码：

package log
    
    import org.apache.spark.sql.{DataFrame, SparkSession}
    
    import scala.collection.mutable.ListBuffer
    
    /**
      * TopN统计spark作业
      */
    object TopNStatJob {
      def main(args: Array[String]) {
        val spark = SparkSession.builder().appName("TopNStatJob")
          .config("spark.sql.sources.partitionColumnTypeInference.enabled",false)
          .master("local[2]").getOrCreate()
        val accessDF = spark.read.format("parquet").load("D:\\BigDataTest\\data\\clean")
        accessDF.printSchema()
        accessDF.show()
        //最受欢迎的topN的课程个数
        videoAccessTopNstat(spark,accessDF)
    
        spark.stop()
      }
      /**
        * 最受欢迎的topN的课程个数
        * @param spark
        * @param accessDF
        */
      def videoAccessTopNstat(spark: SparkSession,accessDF: DataFrame): Unit ={
        /**
          * 使用DataFrame的方式进行统计
          */
        //    //隐式转换
    //    import spark.implicits._
    //    //过滤出当天的视频的个数
    //    val videoAccessTopNDF = accessDF.filter($"day"==="20170511" && $"cmsType"==="video")
    //      .groupBy("day","cmsId")
    //      .agg(count("cmsId")as("times"))
    //      .orderBy($"times".desc)
    //    videoAccessTopNDF.show(false)
    
        //方法二采用sparkSql的方式
        accessDF.createOrReplaceTempView("access_log")
       val videoAccessTopNDF = spark.sql("select day,cmsId,count(1) as times from access_log "
          + "where day='20170511' and cmsType= 'video' "
          + "group by day,cmsId order by times desc")
       videoAccessTopNDF.show(false)
    
        /**
          * 将统计结果写入到MySQL中
          */
        try {
          videoAccessTopNDF.foreachPartition(partitionOfRecords => {
            val list = new ListBuffer[DayVideoAccessStat]
    
            partitionOfRecords.foreach(info => {
              val day = info.getAs[String]("day")
              val cmsId = info.getAs[Long]("cmsId")
              val times = info.getAs[Long]("times")
              /**
                * 不建议大家在此处进行数据库的数据插入
                */
              list.append(DayVideoAccessStat(day, cmsId, times))
            })
              StatDao.insertDayVideoAccessTopN(list)
          })
        } catch {
          case e:Exception => e.printStackTrace()
        }
      }
    }

下面得出的结果：按照某天分析的：

数据库中的数据如下：

现在需要把 这些我们想要得到的数据存放在数据库中，留后期数据可视化使用：

存放进数据库的

修改一个参数就是手记的数据了

1 使用ECharts可视化框架  
1）基本使用

ECharts使用教程

2）静态测试

将下载下来的文件echarts.min.js放在js文件夹下  
在webapp下创建test.html  
test.html
