[jira] [Updated] (VFS-620) FileObject.moveTo(FileObject) API
doesn't work well for a Linux FTP
[ https://issues.apache.org/jira/browse/VFS-620?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
stevezhuang updated VFS-620:
----------------------------
Description:
FileObject.moveTo(FileObject) API doesn't work well for a Linux FTP, especially for setting a user directory as its root directory case,
For example, for a ubuntu vsftpd, which is having "/home/user1" as its root directory, when renaming "/test/test1.txt" to "/test1/test1.txt", it will throw an exception.
In this case, it should consider the workingDirectory(would be "/home/user1") together and append it to the from/to path to make the API work.
Sample codes,
FileObject fileObject = null;
FileObject toFileObject = null;
try {
StandardFileSystemManager fsManager = new StandardFileSystemManager();
fsManager.init();
FileSystemOptions fsOpts = new FileSystemOptions();
FtpFileSystemConfigBuilder.getInstance().setPassiveMode(fsOpts, true);
FtpFileSystemConfigBuilder.getInstance().setUserDirIsRoot(fsOpts, true);
UserAuthenticator auth = new StaticUserAuthenticator(null, "<user>", "<password>");
DefaultFileSystemConfigBuilder.getInstance().setUserAuthenticator(fsOpts, auth);
fileObject = fsManager.resolveFile("ftp://<Replaced address>/test/test.txt", fsOpts);
System.out.println("File exists:" + fileObject.exists());
toFileObject = fsManager.resolveFile("ftp://<Replaced address>/test1/test1.txt", fsOpts);
System.out.println("File exists:" + toFileObject.exists());
if (!toFileObject.exists()) {
toFileObject.createFile();
}
fileObject.moveTo(toFileObject);
} catch (FileSystemException ex) {
ex.printStackTrace();
} finally {
if (fileObject != null) {
try {
fileObject.close();
} catch (FileSystemException ex) {
}
}
if (toFileObject != null) {
try {
toFileObject.close();
} catch (FileSystemException ex) {
}
}
}
And the output,
File exists:true
File exists:false
