Confirmation

The confirmation component asks a user for a simple confirmation. It is essentially a yes-or-no question.spring-doc.cn

@ShellComponent
public class ComponentCommands extends AbstractShellComponent {

	@ShellMethod(key = "component confirmation", value = "Confirmation input", group = "Components")
	public String confirmationInput(boolean no) {
		ConfirmationInput component = new ConfirmationInput(getTerminal(), "Enter value", !no);
		component.setResourceLoader(getResourceLoader());
		component.setTemplateExecutor(getTemplateExecutor());
		ConfirmationInputContext context = component.run(ConfirmationInputContext.empty());
		return "Got value " + context.getResultValue();
	}
}
