用于springboot应用（jar）启、停、状态控制，

一、 SpringBoot程序的shell控制脚本

注意：当前目录中仅有一个jar文件和一个 application-prod.yml 配置文件，可根据您的实际情况做修改。

二、使用效果

1. 直接运行：./startup.sh

2. 启动程序：./startup.sh start

初次启动：

若已启动过：

3. 查看运行状态：./startup.sh stat 或 ./startup.sh check

运行状态：

停止状态：

4. 停止应用：./startup.sh

5. 强制杀掉应用进程：./startup.sh kill
