linux环境java应用通用启动shell脚本

     对于java应用部署在linux环境分两种情况，一为war包，应用入口为编译后的classes文件下的本身应用入口，其启动脚本可参考不错的linux下通用的java程序启动脚本这篇博客。

    一为jar包形式

这种便于打包增量升级，关注于改动的jar即可。此应用的结构正是用微服务框架springboot快速搭建并配合以下shell脚本部署linux。

#!/bin/bash

#此脚本为Linux下启动java程序的通用脚本。（包含启动，停止，重启）
#cd 进入脚本执行的bin目录，sh server.sh start(启动) | stop（停止）| restart(重启)
