java使用oshi獲取系統(tǒng)信息(系統(tǒng)-內(nèi)存-cpu-硬盤等)

OSHI介紹：

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。它不需要安裝任何額外的本機(jī)庫，旨在提供跨平臺(tái)的實(shí)現(xiàn)來檢索系統(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。

代碼示例：

maven引入：

       <dependency>
            <groupId>com.github.oshi</groupId>
            <artifactId>oshi-core</artifactId>
            <version>5.3.6</version>
        </dependency>
        <dependency>
            <groupId>net.java.dev.jna</groupId>
            <artifactId>jna</artifactId>
            <version>5.6.0</version>
        </dependency>
        <!-- https://mvnrepository.com/artifact/net.java.dev.jna/jna-platform -->
        <dependency>
            <groupId>net.java.dev.jna</groupId>
            <artifactId>jna-platform</artifactId>
            <version>5.6.0</version>
        </dependency>

注：oshi-core會(huì)自動(dòng)引入依賴jna和jna-platform，但是如果springboot框架自帶的jna版本跟這個(gè)jar包需要的版本沖突時(shí)，就要手動(dòng)再引入一次，比如5.3.6的oshi-core，依賴的是5.6.0的jna，而我本地的springboot2.2.1自帶的jna時(shí)4.5.2的，這樣有些api可以用，有些api是有問題的，所以統(tǒng)一了5.6.0的版本，具體依賴版本可以去maven倉(cāng)庫官網(wǎng)查詢：
