I found this very simple description on Apache FtpServer's document: Integration with Spring Framework
Apache FtpServer uses Spring Framework to implement the configuration. That also means that we get the added benefit of full integration with regular Spring XML configuration. For example, you can embed the "server" element where ever you like within you Spring configuration, and with FtpServer on the classpath, Spring will wire up the server for you. Nothing else about: 1. Where should I put this configure file? 2. What should the file name be? 3. How could the application find that file? Do I have study Sprint's Configure Framework to know all about it? -- look to the things around you,the immediate world around you, if you are alive,it will mean something to you ——Paul Strand
