一、pom依赖
<groupId>mons</groupId><artifactId>commons-compress</artifactId><version>1.9</version></dependency><dependency><groupId>org.tukaani</groupId><artifactId>xz</artifactId><version>1.5</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>
二、工具类实现
