I would like to ask if there is a way how to check if file already exists in the folder using only Apache Commons.
I have method which uploads into the SFTP folder but it overwrites current files anytime the method is running. The method is set to run every 5 minutes. I need a code which will create and if statement which checks if the file is not at the SFTP location already and then, if not executes my copy method, if there is a file, then skips it.
My copy method looks like this
private void copyFileSFTP(File model, String hour) throws IOException {
StandardFileSystemManager manager = new StandardFileSystemManager();
String dest = String.format("%s/%s/model/%s", destinationPath, hour,
model.getName());
remoteDirectory = String.format("%s/%s/model/", destinationPath, hour);
try {
if (!model.exists())
LOG.error("Error. Local file not found");
// Initializes the file manager
manager.init();
// Setup our SFTP configuration
FileSystemOptions opts = new FileSystemOptions();
SftpFileSystemConfigBuilder.getInstance().setStrictHostKeyChecking(
opts, "no");
SftpFileSystemConfigBuilder.getInstance().setUserDirIsRoot(opts,
false);
SftpFileSystemConfigBuilder.getInstance().setTimeout(opts, 10000);
// Create the SFTP URI using the host name, userid, password, remote
// path and file name
String sftpUri = "sftp://" + userId + ":" + password + "@"
+ serverAddress + "/" + remoteDirectory + model.getName();
**HERE I NEED THE CHECK IF THE MODEL EXISTS ALREADY ON SFTP**
// Create local file object
FileObject localFile = manager.resolveFile(model.getAbsolutePath());
// Create remote file object
FileObject remoteFile = manager.resolveFile(sftpUri, opts);
// Copy local file to sftp server
remoteFile.copyFrom(localFile, Selectors.SELECT_SELF);
LOG.info("File upload successful");
LOG.info("New file has been created.");
LOG.info(dest);
} catch (Exception ex) {
LOG.error(ex);
handleBadPath(model, hour);
} finally {
manager.close();
}
}
Thank you for help.
Use FileObject.exists() method.
