用org.apache.tools.zip压缩/解压缩zip文件
写了一个用org.apache.tools.zip压缩/解压缩zip文件的例子,用来解决中文乱码问题。代码如下：package org.coolyongzi;

boolean result = ZipTools.compressFloderChangeToZip(compressedFile,zipOutputStream,base);
logger.debug("compress [" + compressedFilePath + "] end!");
zipOutputStream.close();
return result;
}
private staticboolean compressFloderChangeToZip(File compressedFile,ZipOutputStream zipOutputStream,String base)
throws IOException
