【轉載】JAVA壓縮 解壓縮zip 並解決linux下中文亂碼

再壓縮前，要設置linux模式， 需要使用第三方ant-1.6.5.jar
如果是文件目錄，則
ZipEntry zipEntry=new ZipEntry(basePath + System.getProperties().getProperty(“file.separator”));
zipEntry.setUnixMode(755);//解決linux亂碼

如果是文件，則
ZipEntry zipEntry=new ZipEntry(base);
zipEntry.setUnixMode(644);//解決linux亂碼

然後在輸出時強制設置編碼:
ZipOutputStream out = new ZipOutputStream(new FileOutputStream(
zipFileName));
out.setEncoding(“GBK”);//解決linux亂碼

全部代碼如下:

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;
