@Command Annotation

[jvalkeal]

@Command annotation is a replacement for @ShellComponent and @ShellMethod.

@ShellComponent was used as a @Component to easily add class container into context as a bean and then methods in it became possible targets as invocation.

@ShellMethod was used to target methods in @ShellComponent bean as candidates as shell commands.

Plan is to do a modern update how @Command overall would work as we don't need separate annotations if we do a bit more spring kung fu for scanning things from a classpath.

• @Command Can be defined on both class and method
• Annotated on a class level would introduce it to be a candidate for command container(bean instance as we need only one).
• Annotated on a method level would target that particular method as a CommandRegistration.
• Annotation on a class level would allow defining some common parameters which has been a requested feature so that there is a less duplication on an actual methods.

Possible field ideas:

public @interface Command {
  String[] command() default {};
  String[] alias() default {};
  String group() default "";
  String description() default "";
  boolean hidden() default false;
  InteractionMode[] interactionMode() default {};
}
