 Not all applications need a fancy web user interface. Sometimes, interacting with an application through an interactive terminal is the most appropriate way to get things done.

The Spring Shell project provides the infrastructure to create such a REPL (Read, Eval, Print Loop) application, letting you concentrate on implementing commands by using the familiar Spring programming model.
