JAVA压缩文件夹包括里面的文件，可以设置压缩后的目录结构

package test.downloadzip;

import java.io.File;

import java.io.FileInputStream;

import java.io.FileOutputStream;

import java.io.IOException;

import java.io.InputStream;

import java.util.TreeSet;

import java.util.zip.ZipEntry;

import java.util.zip.ZipOutputStream;

public static void main(String[] args) throws IOException {

// 需要压缩的目录

File sFolder = new File("D:\\leo\\file\\pic");

// 压缩之后的目录，如果是网络下载情况可以将流写入response就好了

File zipFolder = new File("d:\\zipDown\\test.zip");

ZipFolderMethod(sFolder, zipFolder);

System.out.println("导出成功");

}

public static void ZipFolderMethod(File sFoder, File zipFolder) throws IOException {

// TODO Auto-generated method stub

ZipOutputStream zipoutFolder = new ZipOutputStream(new FileOutputStream(zipFolder));

InputStream in = null;

// zipoutFolder.setEncoding("GBK"); //为解决注释乱码

zipoutFolder.setComment("文件夹的压缩");

// 列出所有文件的路径，保存到集合中，在ListAllDirectory(sFoder)方法中用到递归

String[] pathStr = pathTreeSet.toString().substring(1, pathTreeSet.toString().length() - 1).split(",");

for (int i = 0; i < pathStr.length; i++) {

String filePath = pathStr[i].trim();

StringBuffer pathURL = new StringBuffer();

String[] tempStr = filePath.split("\\\\"); // 这个地方需要注意，在Java中需要“\\\\”表示“\”字符串。

// 这里的变量j是从第几层开始打压缩包

for (int j = 6; j < tempStr.length - 1; j++) {
