I'm start with Retrofit.

I thought of Jackson but has given me problems and I guess there will Retrofit thought about this

I have GET endpoints.

I need convert this:

public class BaseRequest {
    private String param1;
    private String param2;
    private String param3;
    //Getter & Setters ...

}

on a Map <String, String>

i'm using dagger + retrofit.

How do I can do this?

Thanks

You'll need to provide more information on this, do the parameters have the same query param name or different.

If they are different you can just pass them in as a @QueryMap Map<String, String> params being a Map of key/value pairs. Such that the output would be something like

Map<String, String> values = new HashMap<>();
values.put("name1", "value1");
values.put("name2", "value2");
values.put("name3", "value3");

?name1=value1&name2=value2&name3=value3

If they are the same then you need @Query("name") String... values), the output of this would be something like:

List<String> values = new ArrayList<>();
values.add("value1");
values.add("value2");
values.add("value3");

?name=value1&name=value2&name=value3

    yeah i know that i can add in all my entities a method named toMap and and on this any like: `Map map = new HashMap<>(); map.put("param1","value1"); map.put("param2","value2"); //one for member`But do this for all entities? for all members of all entities? :( not good idea i think. – Alberto Marina Dec 18 '14 at 22:31
  • @AlbertoMarina I think you need to clarify the question please. Not understanding what it is you are trying to achieve. This answer relates to dynamically handling query params in a request. Is this what you wanted to know or is it something else you are after? – Phil H Dec 19 '14 at 07:44
  • Ok, sorry. I need convert a POJO on a Map for retrofit. – Alberto Marina Dec 19 '14 at 17:14
  • @AlbertoMarina have you thought of using reflection on the POJO fields and go that route? Iterate over the fields to get the field name and the value, put those into a map. The only thing with that is the field names have to match the query param name you want to send in the url. – Phil H Dec 19 '14 at 18:02
