最近发现用java.util.zip打zip包会有中文乱码问题，从网上找了些方法，是因为java的生成zip的方法不支持编码格式的更改，特此记录下来，中文乱码问题，用ant.jar包下的zip类，因此要将ant.jar包导入的项目中lib文件夹下，在生成zip包的类中导入一下类：

import org.apache.tools.zip.ZipEntry; import org.apache.tools.zip.ZipFile; import org.apache.tools.zip.ZipOutputStream;

 

这是生成zip包的方法，红色是修改后的地方：

public static void zipFile(String baseDir,String fileName) throws Exception{  List fileList=getSubFiles(new File(baseDir));  ZipOutputStream zos=new ZipOutputStream(new FileOutputStream(fileName));  ZipEntry ze=null;  byte[] buf=new byte[BUFFER];  int readLen=0;  for(int i = 0; i <fileList.size(); i++) {  File f=(File)fileList.get(i);  ze=new ZipEntry(getAbsFileName(baseDir, f));  ze.setSize(f.length());  ze.setTime(f.lastModified());     zos.putNextEntry(ze);  InputStream is=new BufferedInputStream(new FileInputStream(f));  while ((readLen=is.read(buf, 0, BUFFER))!=-1) {  zos.write(buf, 0, readLen);  }  zos.setEncoding("GBK");is.close();  }  zos.close();  } 

这两天工作中用到了要打zip包的功能，因此从网上搜集了一些资料，也自己写了一些打包过程中可能要用的方法，在此分享一下：
