1.需求说明
1.1 需求
到现在为止的网页访问量
到现在为止从搜索引擎引流过来的网页访问量
项目总体框架如图所示：
1.2 用户行为日志内容
2.模拟日志数据制作
用Python制作模拟数据，数据包含：
不同的URL地址->url_paths
不同的跳转链接地址->http_refers
不同的搜索关键词->search_keyword
不同的状态码->status_codes
不同的IP地址->ip_slices
#coding=UTF-8
import random
import time
url_paths = [
"class/112.html",
"class/128.html",
"class/145.html",
"class/146.html",
"class/131.html",
"class/130.html",
"class/145.html",
"learn/821.html",
"learn/825.html",
"course/list"
]
http_refers=[
"http://www.baidu.com/s?wd={query}",
"https://www.sogou.com/web?query={query}",
"http://cn.bing.com/search?q={query}",
"http://search.yahoo.com/search?p={query}",
]
search_keyword = [
"Spark+Sql",
"Hadoop",
"Storm",
"Spark+Streaming",
"大数据",
"面试"
]
status_codes = ["200","404","500"]
ip_slices = [132,156,132,10,29,145,44,30,21,43,1,7,9,23,55,56,241,134,155,163,172,144,158]
def sample_url():
return random.sample(url_paths,1)[0]
def sample_ip():
slice = random.sample(ip_slices,4)
return ".".join([str(item) for item in slice])
def sample_refer():
if random.uniform(0,1) > 0.2:
return "-"
refer_str = random.sample(http_refers,1)
query_str = random.sample(search_keyword,1)
return refer_str[0].format(query=query_str[0])
def sample_status():
return random.sample(status_codes,1)[0]
def generate_log(count = 10):
time_str = time.strftime("%Y-%m-%d %H:%M:%S",time.localtime())
f = open("/home/hadoop/tpdata/project/logs/access.log","w+")
while count >= 1:
query_log = "{ip}\t{local_time}\t\"GET /{url} HTTP/1.1\"\t{status}\t{refer}".format(
local_time=time_str,
url=sample_url(),
ip=sample_ip(),
refer=sample_refer(),
status=sample_status())
print(query_log)
f.write(query_log + "\n")
count = count - 1
if __name__ == '__main__':
generate_log(100)
使用Linux Crontab定时调度工具，使其每一分钟产生一批数据。
表达式：
*/1 * * * *编写python运行脚本：
vi log_generator.sh
python /home/hadoop/tpdata/log.py
chmod u+x log_generator.sh
配置Crontab：
crontab -e
*/1 * * * * /home/hadoop/tpdata/project/log_generator.sh
2.Flume实时收集日志信息
开发时选型：
编写streaming_project.conf：
vi streaming_project.conf
exec-memory-logger.sources = exec-source
exec-memory-logger.sinks = logger-sink
exec-memory-logger.channels = memory-channel
exec-memory-logger.sources.exec-source.type = exec
exec-memory-logger.sources.exec-source.command = tail -F /home/hadoop/tpdata/project/logs/access.log
exec-memory-logger.sources.exec-source.shell = /bin/sh -c
exec-memory-logger.channels.memory-channel.type = memory
exec-memory-logger.sinks.logger-sink.type = logger
exec-memory-logger.sources.exec-source.channels = memory-channel
exec-memory-logger.sinks.logger-sink.channel = memory-channel
启动Flume测试：
flume-ng agent \
--name exec-memory-logger \
--conf $FLUME_HOME/conf \
--conf-file /home/hadoop/tpdata/project/streaming_project.conf \
-Dflume.root.logger=INFO,console
启动Zookeeper:
./zkServer.sh start
启动Kafka Server：
./kafka-server-start.sh -daemon $KAFKA_HOME/config/server.properties
其中server.properties：
broker.id=0
############################# Socket Server Settings #############################

启动一个Kafka的消费者(topic用的之前的，没有的话可以新建一个)：
kafka-console-consumer.sh --zookeeper hadoop000:2181 --topic streamingtopic
修改Flume配置文件，使得Flume的sink链接到Kafka：
vi streaming_project2.conf
exec-memory-kafka.sources = exec-source
exec-memory-kafka.sinks = kafka-sink
exec-memory-kafka.channels = memory-channel
exec-memory-kafka.sources.exec-source.type = exec
exec-memory-kafka.sources.exec-source.command = tail -F /home/hadoop/tpdata/project/logs/access.log
exec-memory-kafka.sources.exec-source.shell = /bin/sh -c
exec-memory-kafka.channels.memory-channel.type = memory
exec-memory-kafka.sinks.kafka-sink.type = org.apache.flume.sink.kafka.KafkaSink
exec-memory-kafka.sinks.kafka-sink.brokerList = hadoop000:9092
exec-memory-kafka.sinks.kafka-sink.topic = streamingtopic
exec-memory-kafka.sinks.kafka-sink.batchSize = 5
exec-memory-kafka.sinks.kafka-sink.requiredAcks = 1
exec-memory-kafka.sources.exec-source.channels = memory-channel
exec-memory-kafka.sinks.kafka-sink.channel = memory-channel
启动Flume：
flume-ng agent \
--name exec-memory-kafka \
--conf $FLUME_HOME/conf \
--conf-file /home/hadoop/tpdata/project/streaming_project2.conf \
-Dflume.root.logger=INFO,console
kafka消费者拿到数据：

4.2 连通Kafka
新建Scala文件——WebStatStreamingApp.scala，首先使用Direct模式连通Kafka：
package com.taipark.spark.project
import kafka.serializer.StringDecoder
import org.apache.spark.SparkConf
import org.apache.spark.streaming.kafka.KafkaUtils
import org.apache.spark.streaming.{Seconds, StreamingContext}
/**
* 使用Spark Streaming消费Kafka的数据
*/
object WebStatStreamingApp {
def main(args: Array[String]): Unit = {
if(args.length != 2){
System.err.println("Userage:WebStatStreamingApp ");
System.exit(1);
}
val Array(brokers,topics) = args
val sparkConf = new SparkConf()
.setAppName("WebStatStreamingApp")
.setMaster("local[2]")
val ssc = new StreamingContext(sparkConf,Seconds(60))
val kafkaParams = Map[String,String]("metadata.broker.list"-> brokers)
val topicSet = topics.split(",").toSet
val messages = KafkaUtils
.createDirectStream[String,String,StringDecoder,StringDecoder](
ssc,kafkaParams,topicSet
)
messages.map(_._2).count().print()
ssc.start()
ssc.awaitTermination()
}
}
设定参数：
hadoop000:9092 streamingtopic
在本地测试是否连通：
连通成功，可以开始编写业务代码完成数据清洗(ETL)。
4.3 ETL
新建工具类DateUtils.scala：
package com.taipark.spark.project.utils
import java.util.Date
import org.apache.commons.lang3.time.FastDateFormat
/**
* 日期时间工具类
*/
object DateUtils {
val YYYYMMDDHHMMSS_FORMAT = FastDateFormat.getInstance("yyyy-MM-dd HH:mm:ss")
val TARGET_FORMAT = FastDateFormat.getInstance("yyyyMMddHHmmss")
def getTime(time:String)={
YYYYMMDDHHMMSS_FORMAT.parse(time).getTime
}
def parseToMinute(time:String)={
TARGET_FORMAT.format(new Date(getTime(time)))
}
def main(args: Array[String]): Unit = {
// println(parseToMinute("2020-03-10 15:00:05"))
}
}
新建ClickLog.scala：
package com.taipark.spark.project.domian
/**
* 清洗后的日志信息
*/
case class ClickLog(ip:String,time:String,courseId:Int,statusCode:Int,referer:String)
修改WebStatStreamingApp.scala：
package com.taipark.spark.project.spark
import com.taipark.spark.project.domian.ClickLog
import com.taipark.spark.project.utils.DateUtils
import kafka.serializer.StringDecoder
import org.apache.spark.SparkConf
import org.apache.spark.streaming.kafka.KafkaUtils
import org.apache.spark.streaming.{Seconds, StreamingContext}
/**
* 使用Spark Streaming消费Kafka的数据
*/
object WebStatStreamingApp {
def main(args: Array[String]): Unit = {
if(args.length != 2){
System.err.println("Userage:WebStatStreamingApp ");
System.exit(1);
}
val Array(brokers,topics) = args
val sparkConf = new SparkConf()
.setAppName("WebStatStreamingApp")
.setMaster("local[2]")
val ssc = new StreamingContext(sparkConf,Seconds(60))
val kafkaParams = Map[String,String]("metadata.broker.list"-> brokers)
val topicSet = topics.split(",").toSet
val messages = KafkaUtils
.createDirectStream[String,String,StringDecoder,StringDecoder](
ssc,kafkaParams,topicSet
)
//messages.map(_._2).count().print()
//ETL
// 30.163.55.7 2020-03-10 14:32:01 "GET /class/112.html HTTP/1.1" 404 http://www.baidu.com/s?wd=Hadoop
val logs = messages.map(_._2)
val cleanData = logs.map(line => {
val infos = line.split("\t")
//infos(2) = "GET /class/112.html HTTP/1.1"
val url = infos(2).split(" ")(1)
var courseId = 0
//拿到课程编号
if(url.startsWith("/class")){
val courseIdHTML = url.split("/")(2)
courseId = courseIdHTML.substring(0,courseIdHTML.lastIndexOf(".")).toInt
}
ClickLog(infos(0),DateUtils.parseToMinute(infos(1)),courseId,infos(3).toInt,infos(4))
}).filter(clicklog => clicklog.courseId != 0)
cleanData.print()
ssc.start()
ssc.awaitTermination()
}
}
run起来测试一下：
ETL完成。
4.4 功能一：到现在为止某网站的访问量
使用数据库来存储统计结果，可视化前端根据yyyyMMdd courseid把数据库里的结果展示出来。
选择HBASE作为数据库。要启动HDFS与Zookeeper。
启动HDFS：
./start-dfs.sh
启动HBASE：
./start-hbase.sh
./hbase shell
list
HBASE表设计：
create 'web_course_clickcount','info'
hbase(main):008:0> desc 'web_course_clickcount'
Table web_course_clickcount is ENABLED
web_course_clickcount
COLUMN FAMILIES DESCRIPTION
{NAME => 'info', BLOOMFILTER => 'ROW', VERSIONS => '1', IN_MEMORY => 'false', KEEP_DELETED_CELLS => 'FA
LSE', DATA_BLOCK_ENCODING => 'NONE', TTL => 'FOREVER', COMPRESSION => 'NONE', MIN_VERSIONS => '0', BLOC
KCACHE => 'true', BLOCKSIZE => '65536', REPLICATION_SCOPE => '0'}
1 row(s) in 0.1650 seconds
Rowkey设计：
day_courseid
使用Scala来操作HBASE：
新建网页点击数实体类 CourseClickCount.scala：
package com.taipark.spark.project.domian
/**
* 课程网页点击数
* @param day_course HBASE中的rowkey
* @param click_count 对应的点击总数
*/
case class CourseClickCount(day_course:String,click_count:Long)
新建数据访问层 CourseClickCountDAO.scala：
package com.taipark.spark.project.dao
import com.taipark.spark.project.domian.CourseClickCount
import scala.collection.mutable.ListBuffer
object CourseClickCountDAO {
val tableName = "web_course_clickcount"
val cf = "info"
val qualifer = "click_count"
/**
* 保存数据到HBASE
* @param list
*/
def save(list:ListBuffer[CourseClickCount]): Unit ={
}
/**
* 根据rowkey查询值
* @param day_course
* @return
*/
def count(day_course:String):Long={
0l
}
}
利用Java实现HBaseUtils打通其与HBASE：
package com.taipark.spark.project.utils;
import org.apache.hadoop.conf.Configuration;
import org.apache.hadoop.hbase.client.HBaseAdmin;
import org.apache.hadoop.hbase.client.HTable;
import org.apache.hadoop.hbase.client.Put;
import org.apache.hadoop.hbase.util.Bytes;
import java.io.IOException;
/**
* HBase操作工具类:Java工具类采用单例模式封装
*/
public class HBaseUtils {
HBaseAdmin admin = null;
Configuration configuration = null;
//私有构造方法(单例模式)
private HBaseUtils(){
configuration = new Configuration();
configuration.set("hbase.zookeeper.quorum",
"hadoop000:2181");
configuration.set("hbase.rootdir",
"hdfs://hadoop000:8020/hbase");
try {
admin = new HBaseAdmin(configuration);
} catch (IOException e) {
e.printStackTrace();
}
}
private static HBaseUtils instance = null;
public static synchronized HBaseUtils getInstance(){
if(instance == null){
instance = new HBaseUtils();
}
return instance;
}
//根据表名获取HTable实例
public HTable getTable(String tableName){
HTable table = null;
try {
table = new HTable(configuration,tableName);
} catch (IOException e) {
e.printStackTrace();
}
return table;
}
/**
* 添加一条记录到HBASE表
* @param tableName 表名
* @param rowkey 表rowkey
* @param cf 表的columnfamily
* @param column 表的列
* @param value 写入HBASE的值
*/
public void put(String tableName,String rowkey,String cf,String column,String value){
HTable table = getTable(tableName);
Put put = new Put(Bytes.toBytes(rowkey));
put.add(Bytes.toBytes(cf),Bytes.toBytes(column),Bytes.toBytes(value));
try {
table.put(put);
} catch (IOException e) {
e.printStackTrace();
}
}
public static void main(String[] args) {
// HTable hTable = HBaseUtils.getInstance().getTable("web_course_clickcount");
// System.out.println(hTable.getName().getNameAsString());
String tableName = "web_course_clickcount";
String rowkey = "20200310_88";
String cf = "info";
String column = "click_count";
String value = "2";
HBaseUtils.getInstance().put(tableName,rowkey,cf,column,value);
}
}
测试运行：
测试工具类成功后继续编写DAO的代码：
package com.taipark.spark.project.dao
import com.taipark.spark.project.domian.CourseClickCount
import com.taipark.spark.project.utils.HBaseUtils
import org.apache.hadoop.hbase.client.Get
import org.apache.hadoop.hbase.util.Bytes
import scala.collection.mutable.ListBuffer
object CourseClickCountDAO {
val tableName = "web_course_clickcount"
val cf = "info"
val qualifer = "click_count"
/**
* 保存数据到HBASE
* @param list
*/
def save(list:ListBuffer[CourseClickCount]): Unit ={
val table = HBaseUtils.getInstance().getTable(tableName)
for(ele <- list){
table.incrementColumnValue(
Bytes.toBytes(ele.day_course),
Bytes.toBytes(cf),
Bytes.toBytes(qualifer),
ele.click_count)
}
}
/**
* 根据rowkey查询值
* @param day_course
* @return
*/
def count(day_course:String):Long={
val table = HBaseUtils.getInstance().getTable(tableName)
val get = new Get(Bytes.toBytes(day_course))
val value = table.get(get).getValue(cf.getBytes,qualifer.getBytes)
if (value == null){
0L
}else{
Bytes.toLong(value)
}
}
def main(args: Array[String]): Unit = {
val list = new ListBuffer[CourseClickCount]
list.append(CourseClickCount("2020311_8",8))
list.append(CourseClickCount("2020311_9",9))
list.append(CourseClickCount("2020311_10",1))
list.append(CourseClickCount("2020311_2",15))
save(list)
}
}
测试运行一下，用hbase shell查看：
scan 'web_course_clickcount'
将Spark Streaming处理结果写到HBASE中：
package com.taipark.spark.project.spark
import com.taipark.spark.project.dao.CourseClickCountDAO
import com.taipark.spark.project.domian.{ClickLog, CourseClickCount}

import org.apache.spark.streaming.kafka.KafkaUtils
import org.apache.spark.streaming.{Seconds, StreamingContext}
import scala.collection.mutable.ListBuffer
/**

*/
object WebStatStreamingApp {
def main(args: Array[String]): Unit = {
if(args.length != 2){
System.err.println("Userage:WebStatStreamingApp ");
System.exit(1);
}
val Array(brokers,topics) = args
val sparkConf = new SparkConf()
.setAppName("WebStatStreamingApp")
.setMaster("local[2]")
val ssc = new StreamingContext(sparkConf,Seconds(60))
val kafkaParams = Map[String,String]("metadata.broker.list"-> brokers)
val topicSet = topics.split(",").toSet
val messages = KafkaUtils
.createDirectStream[String,String,StringDecoder,StringDecoder](
ssc,kafkaParams,topicSet
)
//messages.map(_._2).count().print()
//ETL
// 30.163.55.7 2020-03-10 14:32:01 "GET /class/112.html HTTP/1.1" 404 http://www.baidu.com/s?wd=Hadoop
val logs = messages.map(_._2)
val cleanData = logs.map(line => {
val infos = line.split("\t")
//infos(2) = "GET /class/112.html HTTP/1.1"
val url = infos(2).split(" ")(1)
var courseId = 0
//拿到课程编号
if(url.startsWith("/class")){
val courseIdHTML = url.split("/")(2)
courseId = courseIdHTML.substring(0,courseIdHTML.lastIndexOf(".")).toInt
}
ClickLog(infos(0),DateUtils.parseToMinute(infos(1)),courseId,infos(3).toInt,infos(4))
}).filter(clicklog => clicklog.courseId != 0)
// cleanData.print()
cleanData.map(x => {
//HBase rowkey设计：20200311_9
((x.time.substring(0,8)) + "_" + x.courseId,1)
}).reduceByKey(_+_).foreachRDD(rdd =>{
rdd.foreachPartition(partitionRecords =>{
val list = new ListBuffer[CourseClickCount]
partitionRecords.foreach(pair =>{
list.append(CourseClickCount(pair._1,pair._2))
})
CourseClickCountDAO.save(list)
})
})
ssc.start()
ssc.awaitTermination()
}
}
测试：
4.5 功能二：到现在为止某网站的搜索引擎引流访问量
HBASE表设计：
create 'web_course_search_clickcount','info'
设计rowkey：
day_search_1
确定实体类：
package com.taipark.spark.project.domian
/**
* 网站从搜索引擎过来的点击数实体类
* @param day_search_course
* @param click_count
*/
case class CourseSearchClickCount (day_search_course:String,click_count:Long)
开发DAO CourseSearchClickCountDAO.scala：
package com.taipark.spark.project.dao
import com.taipark.spark.project.domian.{CourseClickCount, CourseSearchClickCount}
import com.taipark.spark.project.utils.HBaseUtils
import org.apache.hadoop.hbase.client.Get
import org.apache.hadoop.hbase.util.Bytes
import scala.collection.mutable.ListBuffer
object CourseSearchClickCountDAO {

def save(list:ListBuffer[CourseSearchClickCount]): Unit ={
val table = HBaseUtils.getInstance().getTable(tableName)
for(ele <- list){
table.incrementColumnValue(
Bytes.toBytes(ele.day_search_course),
Bytes.toBytes(cf),
Bytes.toBytes(qualifer),
ele.click_count)
}
}
/**
* 根据rowkey查询值
* @param day_search_course
* @return
*/
def count(day_search_course:String):Long={
val table = HBaseUtils.getInstance().getTable(tableName)
val get = new Get(Bytes.toBytes(day_search_course))
val value = table.get(get).getValue(cf.getBytes,qualifer.getBytes)
if (value == null){
0L
}else{
Bytes.toLong(value)
}
}
def main(args: Array[String]): Unit = {
val list = new ListBuffer[CourseSearchClickCount]
list.append(CourseSearchClickCount("2020311_www.baidu.com_8",8))
list.append(CourseSearchClickCount("2020311_cn.bing.com_9",9))
save(list)
println(count("020311_www.baidu.com_8"))

测试：
5.生产环境部署
不要硬编码，把setAppName和setMaster注释掉：
val sparkConf = new SparkConf()
// .setAppName("WebStatStreamingApp")
// .setMaster("local[2]")
Maven打包部署前，需要将pom中指定build目录的两行注释掉，以防报错：
Maven打包传到服务器：
利用spark-submit提交：
./spark-submit \
--master local[5] \
--name WebStatStreamingApp \
--class com.taipark.spark.project.spark.WebStatStreamingApp \
/home/hadoop/tplib/sparktrain-1.0.jar \
hadoop000:9092 streamingtopic
报错：
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/spark/streaming/kafka/KafkaUtils$
修改，添加jar包spark-streaming-kafka-0-8_2.11：
./spark-submit \
--master local[5] \
--name WebStatStreamingApp \
--class com.taipark.spark.project.spark.WebStatStreamingApp \
--packages org.apache.spark:spark-streaming-kafka-0-8_2.11:2.2.0 \
/home/hadoop/tplib/sparktrain-1.0.jar \
hadoop000:9092 streamingtopic
报错：
java.lang.NoClassDefFoundError: org/apache/hadoop/hbase/client/HBaseAdmin
修改，增加HBASE的jar包：
./spark-submit \
--master local[5] \
--name WebStatStreamingApp \
--class com.taipark.spark.project.spark.WebStatStreamingApp \
--packages org.apache.spark:spark-streaming-kafka-0-8_2.11:2.2.0 \
--jars $(echo /home/hadoop/app/hbase-1.2.0-cdh5.7.0/lib/*.jar | tr ' ' ',') \
/home/hadoop/tplib/sparktrain-1.0.jar \
hadoop000:9092 streamingtopic
运行：
后台运行成功
6.Spring Boot开发
6.1 测试ECharts
新建一个Spring Boot项目，下载ECharts，利用其在线编译，获得echarts.min.js，放在resources/static/js下
pox.xml添加一个依赖：
org.springframework.boot
spring-boot-starter-thymeleaf
resources/templates里做一个test.html：
test
新建java文件：
package com.taipark.spark.web;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.servlet.ModelAndView;
/**
* 测试
*/
@RestController
public class HelloBoot {
@RequestMapping(value = "/hello",method = RequestMethod.GET)
public String sayHello(){
return "HelloWorld!";
}
@RequestMapping(value = "/first",method = RequestMethod.GET)
public ModelAndView firstDemo(){
return new ModelAndView("test");
}
}
测试一下：
成功
6.2 动态实现ECharts
添加repository：
cloudera
https://repository.cloudera.com/artifactory/cloudera-repos/
添加依赖：
org.apache.hbase
hbase-client
1.2.0-cdh5.7.0
创建HBaseUtils.java：
package com.taipark.spark.web.utils;
import org.apache.hadoop.conf.Configuration;
import org.apache.hadoop.hbase.client.*;
import org.apache.hadoop.hbase.filter.Filter;
import org.apache.hadoop.hbase.filter.PrefixFilter;
import org.apache.hadoop.hbase.util.Bytes;
import java.io.IOException;
import java.util.HashMap;
import java.util.Map;
public class HBaseUtils {
HBaseAdmin admin = null;
Configuration configuration = null;
//私有构造方法(单例模式)
private HBaseUtils(){
configuration = new Configuration();
configuration.set("hbase.zookeeper.quorum",
"hadoop000:2181");
configuration.set("hbase.rootdir",
"hdfs://hadoop000:8020/hbase");
try {
admin = new HBaseAdmin(configuration);
} catch (IOException e) {
e.printStackTrace();
}
}
private static HBaseUtils instance = null;
public static synchronized HBaseUtils getInstance(){
if(instance == null){
instance = new HBaseUtils();
}
return instance;
}
//根据表名获取HTable实例
public HTable getTable(String tableName){
HTable table = null;
try {
table = new HTable(configuration,tableName);
} catch (IOException e) {
e.printStackTrace();
}
return table;
}
/**
* 根据表名和输入条件获取HBASE的记录数
* @param tableName
* @param dayCourse
* @return
*/
public Map query(String tableName,String condition) throws Exception{
Map map = new HashMap<>();
HTable table = getTable(tableName);
String cf ="info";
String qualifier = "click_count";
Scan scan = new Scan();
Filter filter = new PrefixFilter(Bytes.toBytes(condition));
scan.setFilter(filter);
ResultScanner rs = table.getScanner(scan);
for(Result result:rs){
String row = Bytes.toString(result.getRow());
long clickCount = Bytes.toLong(result.getValue(cf.getBytes(), qualifier.getBytes()));
map.put(row,clickCount);
}
return map;
}
public static void main(String[] args) throws Exception{
Map map = HBaseUtils.getInstance().query("web_course_clickcount", "20200311");
for(Map.Entry entry:map.entrySet()){
System.out.println(entry.getKey() + ":" + entry.getValue());
}
}
}
测试通过：
定义网页访问数量Bean：
package com.taipark.spark.web.domain;
import org.springframework.stereotype.Component;
/**
* 网页访问数量实体类
*/
@Component
public class CourseClickCount {
private String name;
private long value;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public long getValue() {
return value;
}
public void setValue(long value) {
this.value = value;
}
}
DAO层：
package com.taipark.spark.web.dao;
import com.taipark.spark.web.domain.CourseClickCount;
import com.taipark.spark.web.utils.HBaseUtils;
import org.springframework.stereotype.Component;
import java.util.ArrayList;
import java.util.List;
import java.util.Map;
/**
* 网页访问数量数据访问层
*/
@Component
public class CourseClickDAO {
/**
* 根据天查询
* @param day
* @return
* @throws Exception
*/
public List query(String day) throws Exception{
List list = new ArrayList<>();
//去HBase表中根据day获取对应网页的访问量
Map map = HBaseUtils.getInstance().query("web_course_clickcount", "20200311");
for(Map.Entry entry:map.entrySet()){
CourseClickCount model = new CourseClickCount();
model.setName(entry.getKey());
model.setValue(entry.getValue());
list.add(model);
}
return list;
}
public static void main(String[] args) throws Exception{
CourseClickDAO dao = new CourseClickDAO();
List list = dao.query( "20200311");
for(CourseClickCount model:list){
System.out.println(model.getName() + ":" + model.getValue());
}
}
}
使用JSON需要引入：
net.sf.json-lib
json-lib
2.4
jdk15
Web层：
package com.taipark.spark.web.spark;
import com.taipark.spark.web.dao.CourseClickDAO;
import com.taipark.spark.web.domain.CourseClickCount;
import net.sf.json.JSONArray;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.servlet.ModelAndView;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
/**
* web层
*/
@RestController
public class WebStatApp {
private static Map courses = new HashMap<>();
static {
courses.put("112","某些外国人对中国有多不了解？");
courses.put("128","你认为有哪些失败的建筑？");
courses.put("145","为什么人类想象不出四维空间？");
courses.put("146","有什么一眼看上去很舒服的头像？");
courses.put("131","男朋友心情不好时女朋友该怎么办？");
courses.put("130","小白如何从零开始运营一个微信公众号？");
courses.put("821","为什么有人不喜欢极简主义？");
courses.put("825","有哪些书看完后会让人很后悔没有早看到？");
}
// @Autowired
// CourseClickDAO courseClickDAO;
// @RequestMapping(value = "/course_clickcount_dynamic",method = RequestMethod.GET)
// public ModelAndView courseClickCount() throws Exception{
// ModelAndView view = new ModelAndView("index");
// List list = courseClickDAO.query("20200311");
//
// for(CourseClickCount model:list){
// model.setName(courses.get(model.getName().substring(9)));
// }
// JSONArray json = JSONArray.fromObject(list);
//
// view.addObject("data_json",json);
//
// return view;
// }
@Autowired
CourseClickDAO courseClickDAO;
@RequestMapping(value = "/course_clickcount_dynamic",method = RequestMethod.POST)
@ResponseBody
public List courseClickCount() throws Exception{
ModelAndView view = new ModelAndView("index");
List list = courseClickDAO.query("20200311");
for(CourseClickCount model:list){
model.setName(courses.get(model.getName().substring(9)));
}
return list;
}
@RequestMapping(value = "/echarts",method = RequestMethod.GET)
public ModelAndView echarts(){
return new ModelAndView("echarts");
}
}
下载JQuery，并放到static/js下，新建echarts.html：
web_stat
测试一下：
6.3 Spring的服务器部署
Maven打包并上传服务器
java -jar web-0.0.1.jar
完成~
