IM使用Spring和谷歌的AppEngine和我尝试存储在我的应用程序 Pdf文档前面的所有用户，但我不能找到GcsFile如何将pdf文件存储在谷歌云存储上？
解决你能帮助我吗？
感谢
代码：
GcsFileOptions options = new GcsFileOptions.Builder()
.mimeType("application/pdf")
.acl("public-read")
.build();
GcsOutputChannel writeChannel = gcsService.createOrReplace(filename, options);
ServletFileUpload uploadGcs = new ServletFileUpload();
try
{
byte[] bytes = ByteStreams.toByteArray(stream);
try {
writeChannel.write(ByteBuffer.wrap(bytes));
} finally {
writeChannel.close();
stream.close();
}
} catch (Exception e) {
e.printStackTrace();
}
