Java获取终端设备信息工具类

• 在很多场景中需要获取到终端设备的一些硬件信息等，获取的字段如下：

返回参数

参数	含义	备注
systemName	系统名称
remoteIp	公网ip
localIp	本地ip	取IPV4
mac	mac地址	去掉地址中的"-“或”:"进行记录
cpuSerial	cpu序列号
hardSerial	硬盘序列号
drive	盘符	C
fileSystem	分区格式	NTFS
partitionSize	分区容量	119G
systemDisk	系统盘卷标号
pcName	PC终端设备名称
pcSerial	PC终端设备序列号	仅Mac系统有，其余系统返回"null"
