Java打多�?/span>zip压羃�?/span>

-- ByteArrayOutputStream�l�合org.apache.commons.compress来实�?/span>

也就是很多个zip文�g�Q�但是打包的时候，部分要先集中��C��?/span>zip文�g后，再写入�ȝ��zip文�g�?/span>

可以采用临时文�g夹的方式来解冻I��下面也是一�U�解��x��法，部分代码如下�Q?/span>

File f1 = new File("C:/boot.ini");

File f2 = new File("C:/NTDETECT.COM");

final ByteArrayOutputStream baos = new ByteArrayOutputStream() ;

//changed @ 2009�q?/span>7�?/span>21�?/span>8:37:41

//ArchiveOutputStream ostemp = new ArchiveStreamFactory().createArchiveOutputStream("zip", baos);

ZipArchiveOutputStream ostemp = new ZipArchiveOutputStream(baos);

ostemp.setEncoding("GBK");

ostemp.putArchiveEntry(new ZipArchiveEntry(f1.getName()));

IOUtils.copy(new FileInputStream(f1), ostemp);

ostemp.closeArchiveEntry();

ostemp.putArchiveEntry(new ZipArchiveEntry(f2.getName()));

IOUtils.copy(new FileInputStream(f2), ostemp);

ostemp.closeArchiveEntry();

ostemp.finish();

ostemp.close();

final OutputStream out = new FileOutputStream("c:/test.zip");

ArchiveOutputStream os = new ArchiveStreamFactory().createArchiveOutputStream("zip", out);

os.putArchiveEntry(new ZipArchiveEntry("打包.zip"));

baos.writeTo(os);

os.closeArchiveEntry();

baos.close();

os.finish();

os.close();

[changed @ 2009�q?/span>7�?/span>21�?/span>8:37:41]

当初查资料时�Q�就知道有个��q��错误�Q�自�׃��没发现过�Q�后来发现是因�ؓwinrar 3.8已经解决了这个问题�?/span>

但是��Z��和其他兼容，修改了代码�?/span>

打包后效果如下图�Q?/span>
