在Spring boot中使用OSHI
OSHI是什么
OSHI.是一个基于JNA的免费的本地操作系统和Java的硬件信息库。它不需要安装任何额外的本机库，旨在提供跨平台的实现来检索系统信息，如操作系统版本、进程、内存和CPU使用情况、磁盘和分区、设备、传感器等。（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 & CPU usage, disks & partitions, devices, sensors, etc.）
springboot添加依赖
1、oshi依赖
<dependency>

遇坑
win10 家庭版系统测试运行时 SystemInfo的hardware及os都是null 导致曝出了以下错误：
Exception in thread "main" java.lang.NoSuchMethodError:
com.sun.jna.platform.win32.OleAuto.VariantClear(Lcom/sun/jna/platform/win32/Variant$VARIANT;)Lcom/sun/jna/platform/win32/WinNT$HRESULT;
根据此错误查遍各大网站 大多数答案包括两个问题：
1、需要继续增加依赖jna，jna-platform，slf4j-api 三个jar包
2、oshi和jna的版本不匹配
解决方案是：oshi3.4以上版本余姚匹配jna4.4.0版本
以上2问题可能会解决非springboot用户的问题。 因为boot本身自带了jna和slf4j
***当部署在centos7虚拟机里的时候 再次测试时 成功的返回了所有的数据
结论1：springboot中只需添加oshi依赖(其余已经封装进去)，可根据springboot版本内置jna的版本再确定oshi的版本。win10家庭版不支持oshi。
(最近给win安装docker 家庭版就不支持，所以安装在了虚拟机，
又同样配置的oshi在虚拟机中正常使用，所以一个错误的想法就此萌生，
耽误了一个程序员一上午的时间。shitfuckcao)
结论2：结论1是错的。还是版本的问题 因为centos7中正常使用 所以导致查找问题的方向有误
···在springboot1.5中默认JNA的版本是4.2.2，而我用的oshi版本是3.9.1
···解决办法是：用JNA4.5.2 替换了springboot1.5中默认的4.2.2 win10也正常使用了。
