有时候需要配合算法使用spark定时DP，调用java相关的jar包做数据处理
idea打jar包有以下三种场景
- SpringBoot的Maven项目【Maven打包即可】
- 非SpringBoot的Maven项目【添加maven打包参数，使用Maven打包】
借助maven的配置进行打包，新增以下配置
<build><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方法入口的class --><mainClass>cn.guide.xd.ProductMain</mainClass></manifest></archive></configuration><executions><execution><id>make-assembly</id><phase>package</phase><goals><goal>single</goal></goals></execution></executions></plugin></plugins><resources><resource><directory>src/main/java</directory><includes><include>**/*.xml</include></includes></resource><resource><directory>src/main/resources</directory></resource></resources>
</build>
- 纯java项目【不考虑，场景有限】
