這篇文章將為大家詳細(xì)講解有關(guān)Java中怎么通過(guò)oshi獲取系統(tǒng)和硬件信息，文章內(nèi)容質(zhì)量較高，因此小編分享給大家做個(gè)參考，希望大家閱讀完這篇文章后對(duì)相關(guān)知識(shí)有一定的了解。
Java通過(guò)oshi獲取系統(tǒng)和硬件信息
OSHI是什么
OSHI是一個(gè)基于JNA的免費(fèi)的本地操作系統(tǒng)和Java的硬件信息庫(kù)。 它不需要安裝任何額外的本機(jī)庫(kù)，旨在提供跨平臺(tái)的實(shí)現(xiàn)來(lái)檢索系統(tǒng)信息， 如操作系統(tǒng)版本、進(jìn)程、內(nèi)存和CPU使用情況、磁盤和分區(qū)、設(shè)備、傳感器等。
