扩展开发总结（mvn打包、java -cp 、nohup）

1、mvn 打包，将lib、jar、conf分开
spring-boot-maven-plugin：打包成可执行的文件
maven-jar-plugin：负责将应用程序打包成可执行的jar文件
maven-assembly-plugin：负责将整个项目按照自定义的目录结构打成最终的压缩包，方便实际部署

2、java -cp 运行时加载jar包。

3、nohup

    nohup ${JAVA} ${JAVA_OPT} -cp  $classpath  ${MAIN_CLASS} >start.log 2>&1 &
   nohup ${JAVA} ${JAVA_OPT} -cp  $classpath  ${MAIN_CLASS} >/dev/null 2>nohup.out &
