Spring Shell: Customize named parameter keys

In my previous post, I explained how to customized the prefix while calling named parameters.

 

We can even customize named parameter keys using '@ShellOption' argument.

 

Example

@ShellComponent(value = "Customize Named Parameter keys using @ShellOption")
public class CustomizeNamedParamKeys {
	@ShellMethod(value = "Commands to print Employee Details", key = "print-employee", prefix = "-")
	public String printEmployeeDetails(String name, @ShellOption("emp-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();
	}
}

  For the above example, the possible parameter keys will be -name, emp-age and –emp-city.

 

shell:>print-employee -name "Krishna" emp-age 23 --emp-city "Hyderabad"
Hello Krishna!!!!. You are 23 years old and you are from Hyderabad
