Java压缩 解压缩zip 并解决linux下中文乱码
1:再压缩前,要设置linux模式, 需要使用第三方ant-1.6.5.jar

  如果是文件目录,则

ZipEntry zipEntry=new ZipEntry(basePath + System.getProperties().getProperty("file.separator"));

zipEntry.setUnixMode(755);//解决linux乱码

 
如果是文件,则
ZipEntry zipEntry=new ZipEntry(base);
zipEntry.setUnixMode(644);//解决linux乱码



然后在输出时强制设置编码:

 ZipOutputStream out = new ZipOutputStream(new FileOutputStream(

             zipFileName));

     out.setEncoding("GBK");//解决linux乱码



全部代码如下:



import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;

import java.io.OutputStream;

import org.apache.tools.zip.ZipEntry;

import org.apache.tools.zip.ZipOutputStream;

import org.apache.tools.ant.Project;

import org.apache.tools.ant.taskdefs.Expand;

/**
 * 文件夹压缩,支持win和linux
 * 
 * */

public class ZipUtil

{

	/**
	 * @param inputFileName
	 *            输入一个文件夹
	 * @param zipFileName
	 *            输出一个压缩文件夹,打包后文件名字
	 * @throws Exception
	 */

	public static OutputStream zip(String inputFileName, String zipFileName)
			throws Exception

	{

		return zip(zipFileName, new File(inputFileName));

	}

	private static OutputStream zip(String zipFileName, File inputFile)
			throws Exception

	{

		ZipOutputStream out = new ZipOutputStream(new FileOutputStream(

		zipFileName));

		out.setEncoding("UTF-8");// 解决linux乱码 根据linux系统的实际编码设置,可以使用命令
									// vi/etc/sysconfig/i18n 查看linux的系统编码

		zip(out, inputFile, "");

		out.close();

		return out;

	}

	private static void zip(ZipOutputStream out, File f, String base)
			throws Exception

	{

		if (f.isDirectory())

		{ // 判断是否为目录

			File[] fl = f.listFiles();

			// out.putNextEntry(new org.apache.tools.zip.ZipEntry(base + "/"));

			// out.putNextEntry(new ZipEntry(base + "/"));

			ZipEntry zipEntry = new ZipEntry(base
					+ System.getProperties().getProperty("file.separator"));

			zipEntry.setUnixMode(755);// 解决linux乱码

			out.putNextEntry(zipEntry);

			// base = base.length() == 0 ? "" : base + "/";

			base = base.length() == 0 ? "" : base
					+ System.getProperties().getProperty("file.separator");

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

			{

				zip(out, fl[i], base + fl[i].getName());

			}

		}

		else

		{ // 压缩目录中的所有文件

			// out.putNextEntry(new org.apache.tools.zip.ZipEntry(base));

			ZipEntry zipEntry = new ZipEntry(base);

			zipEntry.setUnixMode(644);// 解决linux乱码

			out.putNextEntry(zipEntry);

			FileInputStream in = new FileInputStream(f);

			int b;

			while ((b = in.read()) != -1)

			{

				out.write(b);

			}

			in.close();

		}

	}

	private static void unzip(String sourceZip, String destDir)
			throws Exception {

		try {

			Project p = new Project();

			Expand e = new Expand();

			e.setProject(p);

			e.setSrc(new File(sourceZip));

			e.setOverwrite(false);

			e.setDest(new File(destDir));

			/*
			 * ant下的zip工具默认压缩编码为UTF-8编码, 而winRAR软件压缩是用的windows默认的GBK或者GB2312编码
			 * 所以解压缩时要制定编码格式
			 */

			e.setEncoding("UTF-8"); // 根据linux系统的实际编码设置

			e.execute();

		} catch (Exception e) {

			throw e;

		}

	}
