Java Swing：自定义压缩工具

篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Java Swing：自定义压缩工具相关的知识，希望对你有一定的参考价值。

1. 声明

当前内容主要为使用Swing来实现一个文件压缩器，借助Apache Commons来实现，内容借鉴：官方文档

主要涉及以下Swing组件

  1. JTable中自定义CellRenderer,CellEditor,隐藏列
  2. JProgressorBar的使用
  3. JDialog的使用
  4. 实现拖拽文件到table中

基本pom依赖

<dependency>
	<groupId>org.apache.commons</groupId>
	<artifactId>commons-compress</artifactId>
	<version>1.20</version>
</dependency>
	<dependency>
	<groupId>org.tukaani</groupId>
	<artifactId>xz</artifactId>
	<version>1.9</version>
</dependency>

2. 界面展示


这里压缩后的文件是可以使用rar进行解压的

3. 压缩的实体的解释

对于压缩文件：aaa/aaa.txt,其中aaa就表示一个文件夹，aaa.txt就是该文件夹中的文件，但是在压缩的时候是只有一个实体名称aaa/aaa.txt，使用的却是aaa文件夹和aaa.txt文件，所以对于这个需要特殊的处理操作！

所以对于压缩文件来讲，只需要考虑文件的名称即可(文件夹在解压时会自动创建)

对于文件aaa.txt是放在根目录，那么只需要使用aaa.txt作为实体名称即可
