实用可靠的springBoot启动shell脚本

该文全是干货，不拖泥带水，springboot部署脚本下边已经列出。 本文涵盖了springBoot jar包的备份和重启，启动后会检测springboot是否成功启动 建议springboot开放一个不需要登录的健康检测接口，也可以引入springBoot自带的健康状态检测的依赖包 我这里是自己写了一个开放的接口，在接口中测试了redis和mysql服务是否正常，如果正常，我则认为系统是重启成功了 http://localhost:$PORT/check/health //我的测试接口，返回内容是200表示一切正常，返回数字1表示数据库异常，返回数字2表示redis异常
