【转载】JAVA压缩 解压缩zip 并解决linux下中文乱码

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;

public class ZipUtil
{
/**

*/
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;

}

}
