使用jar：
<dependency>
<groupId>commons-io</groupId>
<artifactId>commons-io</artifactId>
<version>2.6</version>
</dependency>
<dependency>
<groupId>org.apache.commons</groupId>
<artifactId>commons-compress</artifactId>
<version>1.20</version>
</dependency>
待优化：
1、放到工程中需要把缓存目录写一下
2、压缩前应清楚缓存目录
亮点：
1、使用Try-with-resources
2、文件多重压缩
