spring boot部署启动脚本

#功能：
#1、指定用户运行——未实现
#2、默认logs目录——可否另外指定？
#3、JMX监控——待实现，需要启用第二参数来指定
#4、设置JVM参数（指定程序运行名称、时区、内存大小、GC回收器设置、gc日志文件）
#5、 指定配置文件的环境变量
#6、start 启动时检查程序是否已经启动
#7、stop 停止程序、stop之前会先dump。带完善：kill失败检查，然后用kill -9, 有可能存在多个server
#8、status 查看程序是否运行
#9、restart 重启
#10、dump dump系统状态和jvm信息到文件中
#11、配置文件使用哪种方式更好？
#12、默认的jvm配置
#待补充端口占用检查

#使用：
#1、上传.sh脚本到服务器中,授权脚本执行权限sudo chmod +x ./app.sh
#2、启动示例 ./app.sh start
