创建个人主页网站网络营销网站建设案例

一、创建一个空项目，作为整个项目的基本框架

二、创建SparkStudy模块，用于学习基本的Spark基础

三、创建项目结构

1、在SparkStudy模块下的pom.xml文件中加入对应的依赖，并等待依赖包下载完毕。

在pom.xml文件中加入对应的依赖

​<!-- Spark及Scala的版本号 --><properties><scala.version>2.11</scala.version><spark.version>2.1.1</spark.version></properties><!-- Mysql组件<dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>5.7.22.1</version></dependency> 的依赖 --><!-- Spark各个组件的依赖 --><dependencies><!-- https://mvnrepository.com/artifact/com.thoughtworks.paranamer/paranamer --><dependency><groupId>com.thoughtworks.paranamer</groupId><artifactId>paranamer</artifactId><version>2.8</version></dependency><dependency><groupId>org.apache.spark</groupId><artifactId>spark-core_${scala.version}</artifactId><version>${spark.version}</version></dependency><dependency><groupId>org.apache.spark</groupId><artifactId>spark-sql_${scala.version}</artifactId><version>${spark.version}</version></dependency><dependency><groupId>org.apache.spark</groupId><artifactId>spark-streaming_2.11</artifactId><version>${spark.version}</version></dependency><dependency><groupId>org.apache.spark</groupId><artifactId>spark-mllib_2.11</artifactId><version>2.1.1</version></dependency><dependency><groupId>org.apache.spark</groupId><artifactId>spark-streaming-kafka-0-10_2.11</artifactId><version>2.3.0</version></dependency><dependency><groupId>org.apache.spark</groupId><artifactId>spark-streaming-kafka-0-8_${scala.version}</artifactId><version>2.3.0</version></dependency><dependency><groupId>net.jpountz.lz4</groupId><artifactId>lz4</artifactId><version>1.3.0</version></dependency><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>8.0.18</version></dependency><dependency><groupId>org.apache.flume.flume-ng-clients</groupId><artifactId>flume-ng-log4jappender</artifactId><version>1.7.0</version></dependency><!-- <dependency>--><!-- <groupId>org.apache.spark</groupId>--><!-- <artifactId>spark-streaming-flume-sink_2.10</artifactId>--><!-- <version>1.5.2</version>--><!-- </dependency>--><dependency><groupId>org.apache.spark</groupId><artifactId>spark-hive_2.12</artifactId><version>2.4.8</version></dependency></dependencies><!-- 配置maven打包插件及打包类型 --><build><plugins><plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-compiler-plugin</artifactId><version>3.8.1</version><configuration><source>1.8</source><target>1.8</target></configuration></plugin><plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-assembly-plugin</artifactId><configuration><descriptorRefs><descriptorRef>jar-with-dependencies</descriptorRef></descriptorRefs></configuration></plugin></plugins></build>​

等待依赖包下载完毕

2、若不能自动下载依赖包，则按以下步骤操作

四、创建SCALA目录

四、解决无法创建scala文件问题

验证：

问题解决！

五、编写第一个SCALA程序

成功！
