如何使用java.util.zip对java中的字符串进行存档/解压缩,以便在Google Earth中使用?

用例

问题

使用下面的实现,我收到来自WinZip和googleearth的错误,即存档已损坏或文件无法分别打开。与我构建此模型的其他示例不同的部分是添加字符串的行:

ZipEntry kmlZipEntry = new ZipEntry("doc.kml");
out.putNextEntry(kmlZipEntry);
out.write(kml.getBytes("UTF-8"));

请给我指出正确的方向,以便正确地写这个字符串,使它处于正确的位置 doc.xml 在生成的kmz文件中。我知道如何将字符串写入临时文件,但为了便于理解和提高效率,我非常希望将该操作保留在内存中。

    private static final int BUFFER = 2048;
    private static void kmz(OutputStream os, String kml)
    {
        try{
            BufferedInputStream origin = null;
            ZipOutputStream out = new ZipOutputStream(os);
            out.setMethod(ZipOutputStream.DEFLATED);
            byte data[] = new byte[BUFFER];
            File f = new File("./icons"); //folder containing icons and such
            String files[] = f.list();

            if(files != null)
            {
                for (String file: files) {
                    LOGGER.info("Adding to KMZ: "+ file);
                    FileInputStream fi = new FileInputStream(file);
                    origin = new BufferedInputStream(fi, BUFFER);
                    ZipEntry entry = new ZipEntry(file);
                    out.putNextEntry(entry);
                    int count;
                    while((count = origin.read(data, 0, BUFFER)) != -1) {
                        out.write(data, 0, count);
                    }
                    origin.close();
                }
            }
            ZipEntry kmlZipEntry = new ZipEntry("doc.kml");
            out.putNextEntry(kmlZipEntry);
            out.write(kml.getBytes("UTF-8"));
        }
        catch(Exception e)
        {
            LOGGER.error("Problem creating kmz file", e);
        }
    }

给我演示如何放置 icons 将文件夹放入存档中类似的文件夹中,而不是与 doc.kml .

更新 即使将字符串保存到临时文件中,也会出现错误。啊。
