OSHI is a free JNA-based (native) Operating System and Hardware Information library for Java. It does not require the installation of any additional native libraries and aims to provide a cross-platform implementation to retrieve system information, such as OS version, processes, memory and CPU usage, disks and partitions, devices, sensors, etc.

1、oshi依赖
2020.08.05 最新版本为5.2.2
springboot版本为2.1.0.RELEASE
···在springboot2.1.0.RELEASE 中默认JNA的版本是4.5.2,而我用的oshi版本是5.2.2
需要指定最新的
