# windows下文件名正常，但linux下用ZipOutputStream压缩后中文文件名乱码 #

在windows下文件名正常，但部署linux下文件名却出现乱码  
搞了一个晚上，知道是编码的问题，网上查到的大致有两种解决方面（好像都不行）：  
1、修改java.util.zip下对应的类。这个方法改了太麻烦了，而且ant包中的已经有现成的了，而且也没有用（可能是我没改好吧）  
2、用ant提供的来代替，把import 里的java.util.zip改成org.apache.tools.zip。这种方法在window下支持中文了，但在linux下还是会乱码。

今天再回头看，只要在第二种方法的情况下为ZipOutputStream对象加一句setEncoding("gbk")就可以了。把自己的理解记下来以便大家遇到相似的问题可以查看，说的有有问题还请指出来哦  
解决办法：  
原因：org.apache.tools.zip.ZipOutputStream使用的默认编码是系统编码（window是gbk而linux是utf-8），在window下解压时用的是gbk，因些如果是在linux下压缩的文件，到window下解压就会出现乱码，因些在压缩时就为其指定编码为gbk  
代码如下：  
import org.apache.tools.zip.ZipEntry;  
import org.apache.tools.zip.ZipOutputStream;

public static boolean zipFiles(List inputFileNames, String outputFileName) \{  
       boolean result = true;  
       try \{  
           ZipOutputStream out = null;  
           try \{  
               File parent = new File(new File(outputFileName).getParent()); // 得到父文件夹  
               if (!parent.exists()) \{  
                   parent.mkdirs();  
               \}  
               out = new ZipOutputStream(new FileOutputStream(outputFileName));  
               out.setEncoding("gbk");//指定编码为gbk，否则部署到linux下会出现乱码  
               File inputFile = null;  
               for (Object obj:inputFileNames) \{      
                   Object\[\] input = (Object\[\])obj;  
                   if(input.length != 2)  
                       continue;  
                   inputFile = new File((String) input\[0\]);  
                   String fileN = (String)input\[1\];  
                   zip(out, inputFile, fileN);  
               \}  
               System.out.println("zip   done ");  
           \} catch (Exception e) \{  
               result = false;  
           \} finally \{  
               if (out != null)  
                   out.close();  
           \}  
       \} catch (Exception e) \{  
           result = false;  
           e.printStackTrace();  
       \}  
       return result;  
    \}

private static boolean zip(ZipOutputStream out, File file, String base) \{  
       boolean result = true;  
       try \{  
           if (file.isDirectory()) \{  
               File\[\] subfiles = file.listFiles();  
               if (base.length() != 0) \{  
                   out.putNextEntry(new ZipEntry(base + File.separator));  
                   base += File.separator;  
               \}

for (int i = 0; i < subfiles.length; i++) \{  
                   zip(out, subfiles\[i\], base + subfiles\[i\].getName());  
               \}  
           \} else \{  
               String filename = base;//java.net.URLEncoder.encode(base,"UTF-8");  
               out.putNextEntry(new ZipEntry(filename));  
               FileInputStream in = new FileInputStream(file);  
               int b;  
               System.out.println(filename);  
               try \{  
                   while ((b = in.read()) != -1) \{  
                       out.write(b);  
                   \}  
               \} catch (Exception e) \{  
                   result = false;  
               \} finally \{  
                   in.close();  
               \}  
           \}  
       \} catch (Exception e) \{  
           result = false;  
       \}  
       return result;  
    \}
