【Project】kafka+flume+davinci广告点击实时分析系统

news 2025/7/21 11:58:33

一、项目需求分析

某电商平台需实现广告实时点击分析系统，核心需求为实时统计以下内容的Top10：

各个广告的点击量
各个省份的广告点击量
各个城市的广告点击量

通过实时掌握广告投放效果，为广告投放策略调整和大规模投入提供依据，以实现公司经济回报最大化。

二、数据流程设计

数据流程如下：

服务器产生的广告点击日志，由Flume进行实时采集
Flume将采集到的数据写入Kafka消息队列
Spark Streaming从Kafka消费数据并进行实时计算
计算结果一方面入库到MySQL数据库，另一方面通过连接Davinci进行BI分析，实现数据可视化展示

三、开发步骤

3.1 数据准备

数据集文件名为ad.log，包含电商平台广告点击日志，数据格式为：时间、省份ID、城市ID、用户ID、广告ID。

样本数据示例：

1516609143867 6 7 64 16
1516609143869 9 4 75 18
1516609143869 1 7 87 12

3.2 业务建表

在MySQL节点创建advertise数据库：create database advertise;

创建相关数据表：

adversisecount表（存储广告点击量）

CREATE TABLE adversisecount(adname VARCHAR(20) NOT NULL,COUNT INT(11) NOT NULL
);

provincecount表（存储省份广告点击量）

create table provincecount(province varchar(20) not null,count int(11) not null
);

citycount表（存储城市广告点击量）

CREATE TABLE citycount(city VARCHAR(20) NOT NULL,COUNT INT(11) NOT NULL
);

执行advertiseinfo.sql、distinctcode.sql脚本

CREATE DATABASE /*!32312 IF NOT EXISTS*/`advertise` /*!40100 DEFAULT CHARACTER SET utf8 */;USE `advertise`;/*Table structure for table `advertiseinfo` */DROP TABLE IF EXISTS `advertiseinfo`;CREATE TABLE `advertiseinfo` (`aid` int(11) NOT NULL AUTO_INCREMENT,`name` varchar(50) DEFAULT NULL,PRIMARY KEY (`aid`)

3.3 模拟生成数据

编写模拟程序：使用Java编写AnalogData类，实现从输入文件读取数据并按一定速度写入输出文件，模拟实时产生的广告点击日志。

import java.io.*;public class AnalogData_v2 {public static void main(String[] args) {// 参数校验if (args.length < 2) {System.err.println("用法: java AnalogData <输入文件路径> <输出文件路径>");System.exit(1);}String inputFile = args[0];String outputFile = args[1];try {readData(inputFile, outputFile);} catch (FileNotFoundException e) {System.err.println("错误: 文件不存在 - " + e.getMessage());} catch (UnsupportedEncodingException e) {System.err.println("错误: 不支持的编码 - " + e.getMessage());} catch (IOException e) {System.err.println("IO异常: " + e.getMessage());} catch (InterruptedException e) {System.err.println("操作被中断: " + e.getMessage());Thread.currentThread().interrupt(); // 恢复中断状态}}public static void readData(String inputFile, String outputFile)throws IOException, InterruptedException {// 使用try-with-resources自动关闭输入/输出流try (BufferedReader reader = new BufferedReader(new InputStreamReader(new FileInputStream(inputFile), "GBK"));BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(outputFile, true)))) {String line;int counter = 1;while ((line = reader.readLine()) != null) {System.out.printf("第%d行：%s%n", counter, line);writer.write(line);writer.newLine(); // 使用平台无关的换行符writer.flush();   // 确保数据写入磁盘counter++;Thread.sleep(1000); // 控制处理速度}}}
}

项目打包编译：在IDEA中编译打包项目为bigdata.jar，上传至MySQL节点的/root/sparkKS/lib目录。
编写shell脚本：
- 在/root/sparkKS/目录创建ad.sh脚本，用于执行模拟数据程序
- 创建common.sh脚本定义环境变量等配置
- 给ad.sh脚本授权：chmod u+x ad.sh

3.4 业务代码实现

引入项目依赖：在pom.xml文件中添加MySQL连接、Spark Streaming及Kafka相关依赖。

开发Spark Streaming应用程序：
- 配置Spark Streaming和Kafka连接参数
- 从Kafka读取数据并进行过滤处理
- 分别统计各个广告、省份、城市的点击量
- 通过foreachRDD和foreachPartition将统计结果写入MySQL数据库，实现数据的更新或插入操作

模拟产生数据：执行ad.sh脚本，将数据写入指定文件，模拟实时日志

3.6 Davinci数据可视化分析

启动Davinci服务并登录
创建新项目和数据源连接（连接到MySQL的advertise数据库）
创建视图（view）：
- 广告点击前10统计：关联adversisecount和advertiseinfo表
