At next poll Camel, will try the file again, and this time maybe the read-lock could be granted. Use a value of 0 or lower to indicate forever. Currently fileLock, changed and rename support the timeout.

The number of subsequent error polls failed due some error that should happen before the backoffMultipler should kick-in. The number of subsequent idle polls that should happen before the backoffMultipler should kick-in. The multiplier is then the number of polls that will be skipped before the next actual attempt is happening again.

If greedy is enabled, then the ScheduledPollConsumer will run immediately again, if the previous run polled 1 or more messages. Specifies a maximum limit of number of fires. So if you set it to 1, the scheduler will only fire once. If you set it to 5, it will only fire five times. A value of zero or negative means fire forever. This option allows you to configure the logging level for that. By default each consumer has its own single threaded thread pool.

To use a cron scheduler from either camel-spring or camel-quartz component. Use value spring or quartz for built in scheduler. To configure additional properties when using a custom scheduler or any of the Quartz, Spring based scheduler. Built-in sort by using the File Language.

Supports nested sorts, so you can have a sort by file name and as a 2nd group sort by modified date. When using the ftpClient. If you only want trust selective certificates, you have to configure the trust store with the ftpClient. You can mix and match and have use both prefixes, for example to configure date format or timezones. If you do not like having many and long configuration in the url you can refer to the ftpClient or ftpClientConfig to use by letting Camel lookup in the Registry for it.

You can use multiple FTP consumers to poll from different endpoints. It is only a single endpoint that does not support concurrent consumers. This component is an extension of the File component. So there are more samples and details on the File component page. You have to configure it explicitly if you want it to delete the files or move them to another location. The regular File consumer is different as it will by default move files to a. The reason Camel does not do this by default for the FTP consumer is that it may lack permissions by default to be able to move or delete files.

The option readLock can be used to force Camel not to consume files that is currently in the progress of being written. However, this option is turned off by default, as it requires that the user has write access. See the options table at File2 for more details about read locks. There are other solutions to avoid consuming files that are currently being written over FTP; for instance, you can write to a temporary destination and move the file after it has been written.

That prevents you from moving files outside the FTP area. If you want to move files to another area you can use soft links and move files into a soft linked folder. Specifies the output file name relative to the endpoint directory to be used for the output message when sending to the endpoint. If this is not present and no expression either, then a generated message ID is used as the filename instead. This header is set by Camel and its purpose is providing end-users the name of the file that was written.

The two set of libraries see top has different API for setting timeout. You can use the connectTimeout option for both of them to set a timeout in millis to establish a network connection. All timeout values are in millis. Camel supports consuming from remote FTP servers and downloading the files directly into a local work directory. This avoids reading the entire remote file content into memory as it is streamed directly into the local file using FileOutputStream.

Camel will store to a local file with the same name as the remote file, though with. Afterwards, the file is renamed to remove the. And finally, when the Exchange is complete the local file is deleted. So if you want to download files from a remote FTP server and store it as files then you need to route to a file endpoint such as:.

The route above is ultra efficient as it avoids reading the entire file content into memory. It will download the remote file directly to a local file stream. The java. File handle is then used as the Exchange body. The file producer leverages this fact and can work directly on the work file java.

File handle and perform a java. Camel FTP can operate in two modes in terms of traversing directories when consuming files eg downloading or producing files eg uploading. You may want to pick either one depending on your situation and security issues.

Some Camel end users can only download files if they use stepwise, while others can only download if they do not. The difference between the two of them is best illustrated with an example. Suppose we have the following directory structure on the remote FTP server we need to traverse and download files:.

Camel supports pluggable filtering strategies. This strategy it to use the build in org. GenericFileFilter in Java. You can then configure the endpoint with such a filter to skip certain filters before being processed.

In the sample we have built our own filter that only accepts files starting with report in the filename. And then we can configure our route using the filter attribute to reference our filter using notation that we have defined in the spring XML file:. The ANT path matcher is a filter that is shipped out-of-the-box in the camel-spring jar. So you need to depend on camel-spring if you are using Maven.

To use an HTTP proxy to connect to your remote host, you can configure your route in the following way:. You can also assign a user name and password to the proxy, if necessary. Please consult the documentation for com.

Proxy to discover all options. If you want to explicitly specify the list of authentication methods that should be used by sftp component, use preferredAuthentications option. You can also use this with ConsumerTemplate. For example to download a single file if it exists and grab the file content as a String type:.

When using ftp with Spring Boot make sure to use the following Maven dependency to have support for auto configuration:. I use the route. Improve this question. Add a comment. Active Oldest Votes. This should work. Improve this answer. I have the same problem — atoua. Make sure this is correct. I have 3 files. If this option is set to false , then the message body will be null , but the consumer will still trigger a Camel Exchange that has details about the file such as file name, file size, etc.

It's just that the file will not be downloaded. This option is ignored if download is false or is localWorkDirectory is provided. This option is useful for working with large remote files.

If option useSecureDataChannel has been enabled and this option has not been explicit set, then value 0 is used. Default is explicit false. SFTP only: Camel 2. Set the private key file passphrase to that the SFTP endpoint can do private key verification.

Some example include:password,publickey. If not specified the default list from JSCH will be used. Some examples include: aesctr,aescbc,3des-ctr,3des-cbc,blowfish-cbc,aescbc,aescbc. Since some FTP server may not support to list the file directly, if the option is false, camel-ftp will use the old way to list the directory and check if the file exists.

Note from Camel 2. This can be used to speed up the process if the FTP server has a lot of files. Possible values are: no , yes and ask. Note: The default in Camel 2. Specifies the maximum reconnect attempts Camel performs when it tries to connect to the remote FTP server. Use 0 to disable this behavior. This corresponds to using ftpClient. For SFTP this option is also used when attempting to connect. A good idea is to configure this to a value such as 5 minutes to not hang a connection.

For SFTP there is no data timeout. This allows a custom pollStrategy to deal with the exception, for example to stop the consumer or the likes.

Use help site to see which site commands your FTP server supports. Stepwise means that it will CD one directory at a time. See more details below. You can disable this in case you can't use this approach. Since Camel 2. Specify a level from 1 to Thanks hk Thanks for your help mate. Add a comment. Active Oldest Votes.

FTPClientConfig instance. If you only want trust selective certificates, you have to configure the trust store with the ftpClient. See File2 as all the options there also applies for this component. You can use multiple FTP consumers to poll from different endpoints. It is only a single endpoint that does not support concurrent consumers.

The FTP producer does not have this issue, it supports concurrency.
