spring boot工程下maven打包加载本地项目lib下的jar包的方法

1 更改dependency

        
            com.cloudera
            ImpalaJDBC41
            2.6.3
            system
            ${project.basedir}/src/main/resources/lib/ImpalaJDBC41-2.6.3.jar
        

2 更改plugins插件

	org.springframework.boot
	spring-boot-maven-plugin
	
		true
	

3 maven 打包

mvn -U clean package assembly:assembly -Dmaven.test.skip=true

4 运行java进程

java -XX:+UseConcMarkSweepGC -XX:CMSInitiatingOccupancyFraction=70 -XX:+CMSParallelRemarkEnabled -XX:+HeapDumpOnOutOfMemoryError -jar /home/dev/work/core-data-board/target/core-data-board/lib/core-data-board-0.0.1.jar

另外是一个网友分享的此类问题的几种处理方法，其中可以打包mvn -install先将依赖的本地jar包放入本地maven仓库
https://blog.csdn.net/do_you_like_van_game/article/details/96148321

其中的解决方案二:

将自己需要依赖的jar 打包到本地maven 库 (前提的配置好本地mvn)

打开cmd 窗口 输入， 红色的是依赖jar包位置，目的就是将其按照maven流程放入本地maven仓库

mvn install:install-file -Dfile=c:/xxx/xxx.jar -DgroupId=jeewx -DartifactId=jeewx-Dversion=1.0 -Dpackaging=jar
