[FIXED] Is it possible to group JSON fields into one property using Jackson?

Issue

I'm wondering if there is any way to deserialize several JSON fields to just one Java property. E.g. given this JSON:

{
  "id" : "1",
  "name" : "Bartolo",
  "address" : "whatever",
  "phone" : "787312212"
}

deserialize it to this class:

public class Person {

    public String id;
    public String name:

    @JsonProperty(names = {"address", "phone"}) //something like this
    public String moreInfo;

}

so moreInfo equals to "whatever, 787312212" or something similar.

Is this possible without using custom deserializer?

Solution

You could use the @JsonCreator annotation like following:

String json = {"id" : "1",  "name" : "Bartolo", "address" : "whatever", "phone" : "787312212" }

ObjectMapper mapper = new ObjectMapper();
Person person = mapper.readValue(json , Person.class);

and in the constructor of your Person class add this

@JsonCreator
public Person(@JsonProperty("address") String address, @JsonProperty("phone") String phone) {
    this.moreInfo = address + "," phone;
}
