1. 法 1:maven 打包
pom.xml 文件
<plugins>
<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<configuration>
<appendAssemblyId>false</appendAssemblyId>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
<archive>
<manifest>
<!-- 此处指定 main 办法入口的 class --> <mainClass>ch.kmeans2.SparkStreamingKMeansKafkaExample</mainClass>
</manifest>
</archive>
</configuration>
<executions>
<execution>
<id>make-assembly</id>

而后应用 mvn clean package 命令进行打包,如果提交到集群运行遇到 Exception in thread “main” java.lang.AbstractMethodError,思考我的项目中 spark 的版本和集群运行版本是否始终
2. 法 2:idea 打包
Project->Module Setting->Artifacts
而后 Build Artifact 输入 jar 包
