![]() ![]() ![]() I defined a custom UserManager class to manage FTP user accounts. I've done so in the Github repository for this video. And, you can easily embed it inside a Spring application. To implement the algorithm above, create a utility class looks like this: public class FTPUtil Supposing you put the Apache Commons Net library jar file into the same directory of the source files, type the following command to compile the utility class and the test program: The Apache FTP Server is a super scalable, lightweight, all-Java implementation of the FTP protocol. Return if the directory is empty or if the last item is processed.Upload this sub directory by repeating the step 1, 2 and 3.If the item is a file, upload the file to the server.Here’s the algorithm we’d like to suggest: In other words, uploading a directory is similar to copy a directory from the local computer to the FTP server, keeping the copied directory’s structure as same as the original one. We have to re-create the whole directory structure on the server, then do uploading every single file to its proper location.many directories and files nested together, so we should build an algorithm which is able to iterate over the directory’s content recursively (using recursion algorithm). The directory being uploaded may have a quite complex structure, i.e.FtpServerFactory serverFactory new FtpServerFactory() FtpServer server serverFactory.createServer() // start the server server. Getting a basic server up and running is as simple as. However, uploading a whole directory is a different story, as it requires some extra work and effort: FtpServer is designed to be easily embedded into your application. Uploading a single file to a FTP server is not a tricky thing. ![]()
