一、引入jar包
本項目主要使用第開源jar包：https://github.com/oshi/oshi
<dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>RELEASE</version> </dependency> <!-- https://mvnrepository.com/artifact/com.github.oshi/oshi-core --> <dependency> <groupId>com.github.oshi</groupId> <artifactId>oshi-core</artifactId> <version>3.5.0</version> </dependency>
