I suggest using a provider and the awesome (obviously) JCommander
library<http://jcommander.org>
.
class Main {
private Arg arg = new Arg();
public static void main(String[] args) throws Exception {
class Arg {
@Parameter(names = "-long")
public long l;
}
new JCommander(arg).parse("-lon", "32");
}
@Provider
public Arg getArg() {
return arg;
}
}
then simply
@Injectprivate Arg arg;
