1、添加pom依赖
<!-- tar解压依赖 -->
<dependency>
<groupId>org.apache.commons</groupId>
<artifactId>commons-compress</artifactId>
<version>1.20</version>
</dependency>
<!-- rar解压依赖 -->
<dependency>
<groupId>net.sf.sevenzipjbinding</groupId>
<artifactId>sevenzipjbinding</artifactId>
<version>16.02-2.01</version>
</dependency>
<dependency>
<groupId>net.sf.sevenzipjbinding</groupId>
<artifactId>sevenzipjbinding-all-platforms</artifactId>
<version>16.02-2.01</version>
</dependency>
2、具体逻辑代码
