Spring Shell: Specify multiple keys to a parameter

Using ‘@ShellOption’ argument, you can specify multiple keys for a single parameter.

 

Example

@ShellComponent(value = "Specify Multiple Named Parameter keys using @ShellOption")
public class CustomizeMultipleNamedKeysForSingleParameter {
	@ShellMethod(value = "Commands to print Person Details", key = "print-person", prefix = "-")
	public String printPersonDetails(String name, @ShellOption({"-emp-age", "-age"}) int age,
			@ShellOption("--emp-city") String city) {

		StringBuilder builder = new StringBuilder();

		builder.append("Hello ").append(name).append("!!!!").append(". You are ").append(age)
				.append(" years old and you are from ").append(city);

		return builder.toString();
	}
}

  As you see above snippet, I defined two shell options {"-emp-age", "-age"} for the parameter age. So you can use either -emp-age or -age while executing the command "print-person".

 

shell:>print-person -name "Krishna" -emp-age 45 --emp-city "Chennai"
Hello Krishna!!!!. You are 45 years old and you are from Chennai
shell:>
shell:>print-person -name "Krishna" -age 45 --emp-city "Chennai"
Hello Krishna!!!!. You are 45 years old and you are from Chennai
