    System.out.print(new Person().getSons().count());
  }
} 

just like the code showed about,how to inject a existing Map object into a bean by guice ?

Answer 1

I suspect you want to use a TypeLiteral

You will then need to use this bind method .

Another option would be to wrap up your Map in a simpler type, a PersonAccess , perhaps. This might be better anyway since it could hide the implementation of the lookup.
