Here is a fully contained example, you don’t even need a provider. Launch
it and you'll get "Value: 32".
@Singletonclass Arg {
@Parameter(names = "-long")
public long l;
}
public class Main {
@Inject
private Arg arg;
public static void main(String[] args) throws Exception {
Injector inj = Guice.createInjector();
inj.getInstance(Main.class).f();
inj.getInstance(B.class).showInjection();
}
public void f() {
new JCommander(arg).parse("-long", "32");
}
}
class B {
@Inject
private Arg arg;
public void showInjection() {
System.out.println("Value: " + arg.l);
}
}
