JAVA解压tar、zip、rar、gz、7z文件
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> <!-- zip解压依赖 --> <dependency> <groupId>org.apache.ant</groupId> <artifactId>ant</artifactId> <version>1.10.10</version> </dependency> <!-- 7z解压依赖 --> <dependency> <groupId>org.tukaani</groupId> <artifactId>xz</artifactId> <version>1.9</version> </dependency>
2、具体逻辑代码
