### Maven ###

在项目的pom.xml的dependencies中加入以下内容:

<dependency>
        <groupId>cn.hutool</groupId>
        <artifactId>hutool-all</artifactId>
        <version>4.5.15</version>
    </dependency>
    
    <dependency>
        <groupId>com.github.oshi</groupId>
        <artifactId>oshi-core</artifactId>
        <version>3.9.1</version>
    </dependency>
    </dependencies>
