前文描述：

之前公司有一个 .exe 的工具：A：可以把一个文件放进压缩包，B：可以检验被放进压缩包的文件。

现在需要用Java编写一个类似的工具。

1、工具写好之后进行验证时发现：

1）用java代码工具进行AB操作时完全正常。

2）用java代码工具进行A操作用exe工具进行B操作正常。

3）用exe工具进行A操作，用java工具进行B操作抛出异常。异常如下：

java.util.zip.ZipException: invalid entry size (expected 67324752 but got 5896 bytes)

2、问题详细信息：

exe进行A操作的代码：

//拷贝zip文件
            string tmpZipPath = zipFolder + "\\" + mark + "_" + zipFileName;
            System.IO.File.Copy(zipPath, tmpApkPath, true);


            //将mark对应到文件添加到apk
            using (ICSharpCode.SharpZipLib.Zip.ZipFile zip = new ICSharpCode.SharpZipLib.Zip.ZipFile(tmpZipPath)) 
            {
                zip.BeginUpdate();
                zip.Add(markPath, "META-INF\\" + markEnc);
                zip.CommitUpdate();
                zip.Close();
            }

java工具进行B操作的代码：

ZipInputStream zis = new ZipInputStream(new FileInputStream(file));
		ZipEntry entry = null;
		while((entry = zis.getNextEntry()) != null){
			String entryName = entry.getName();
			if(entryName.contains(ChannelUtil.CHANNEL_DIR+ChannelUtil.MARK_FILE_MARKS)){
				break;
			}
		}
		zis.closeEntry();
		zis.close();

3.解决办法：

java工具进行B操作的代码修改为：

ZipFile zipFile = new ZipFile(file);
		Enumeration<? extends ZipEntry> enumeration= zipFile.entries();
		 
		 while(enumeration.hasMoreElements()){
			String entryName = enumeration.nextElement().getName();
			if(entryName.startsWith(ChannelUtil.CHANNEL_DIR+ChannelUtil.MARK_FILE_MARKS)){
				break;
			}
		 }
		 zipFile.close();
