Spring Shell is an interactive shell that can be easily extended with commands using a Spring based programming model

Spring Shell's features include

  • A simple, annotation driven, programming model to contribute custom commands
  • Use of Spring Boot auto-configuration functionality as the basis for a command plugin strategy
  • Tab completion, colorisation, and script execution
  • Customisation of command prompt, shell history file name, handling of results and errors
  • Dynamic enablement of commands based on domain specific criteria
  • Integration with the bean validation API
  • Already built-in commands, such as clear screen, gorgeous help, exit
  • ASCII art Tables, with formatting, alignment, fancy borders, etc.

The project homepage can be found at https://projects.spring.io/spring-shell/ while the latest documentation is available at http://docs.spring.io/spring-shell/docs/current/reference/htmlsingle/
