在SMB上使用smbj重命名文件失败

Question

我正在努力使用com.hierynomus.smbj将内容重命名为SMB的文件。文件生成时带有内容，但重命名后内容就消失了。

以下实现重命名文件:

public void rename(String pathFrom, String pathTo) {
pathFrom = formatPath(pathFrom);
pathTo = formatPath(pathTo);
Set<SMB2ShareAccess> shareAccessSet = new HashSet<>();
shareAccessSet.add(SMB2ShareAccess.FILE_SHARE_READ);
shareAccessSet.add(SMB2ShareAccess.FILE_SHARE_WRITE);
shareAccessSet.add(SMB2ShareAccess.FILE_SHARE_DELETE);
Set<FileAttributes> fileAttributes = new HashSet<>();
fileAttributes.add(FileAttributes.FILE_ATTRIBUTE_NORMAL);
Set<SMB2CreateOptions> createOptions = new HashSet<>();
SMB2CreateDisposition smb2CreateDisposition = SMB2CreateDisposition.FILE_OVERWRITE_IF;
if (isFolder(pathFrom)) {
createOptions.add(SMB2CreateOptions.FILE_DIRECTORY_FILE);
smb2CreateDisposition = SMB2CreateDisposition.FILE_OPEN_IF;
}
else if (isFile(pathFrom)) {
createOptions.add(SMB2CreateOptions.FILE_NON_DIRECTORY_FILE);
}
else {
throw new IllegalArgumentException("Path '" + pathFrom + "' can't be resolved to file nor directory");
}
try (DiskEntry file = this.smbShare.open(pathFrom, of(AccessMask.MAXIMUM_ALLOWED), fileAttributes, shareAccessSet,
smb2CreateDisposition, createOptions)) {
file.rename(pathTo, true);
}
}

也许我搞砸了属性和选项在smbShare.open-功能?

Answer 1

嗯…我把SMB2CreateDisposition的属性弄乱了

解:smb2CreateDisposition = SMB2CreateDisposition.FILE_OPEN_IF;代替smb2CreateDisposition = SMB2CreateDisposition.FILE_OVERWRITE_IF;

前者打开(1.)或创建(2.)文件。后者将覆盖现有文件。
