I have a map like the following: Map<MiObjeto, List<OtroObjeto>> and I want to convert it to a POJO that is defined in the following way:
public class UnObjetoMas {
private MiObjeto miObjeto;
private List<OtroObjeto> otrosObjetos;
//Getters and setters
}
How could I make that conversion?
A complete map can not be converted to that POJO, in any case it could become a Collection, for example a List, for which you could do something like this:
List<UnObjetoMas> list = new ArrayList<>();
for(Map.Entry<MiObjeto, List<OtroObjeto>> e : mapa.entrySet()){
list.add(new UnObjetoMas(e.getKey(),e.getValue()));
}
//suponiendo que existe un constructor en la clase UnObjetoMas
public UnObjetoMas(MiObjeto miobj,List<OtroObjeto> otros){
this.miObjeto = miobj;
this.otrosObjetos = otros;
}
To put it another way, your UnObjetoMas class represents an Entry of the Map but it is not designed to represent a complete Map. Greetings
There are several options, one is through Jackson , using the class ObjectMapper and its method convertValue :
ObjectMapper mapper = new ObjectMapper();
MyPojo pojo = mapper.convertValue(myMap, UnObjetoMas.class);
