Jordi :
I'm coding an Spring-boot service and I'm using jackson ObjectMapper
in order to handle with my jsons.
I need to split a json like this:
{
"copy": {
"mode": "mode",
"version": "version"
},
"known": "string value",
"unknown": {
"field1": "sdf",
"field2": "sdfdf"
},
"unknown2": "sdfdf"
}
I mean, my bean is like this:
public class MyBean {
private CopyMetadata copy;
private String known;
private Object others;
}
I'd like to populate known fields to MyBean
properties, and move the other unknown properties inside MyBean.others
property.
Known properties are which are placed as a field inside MyBean
.
Any ideas?

A possible solution to this problem is to use the jackson annotations @JsonAnyGetter and @JsonAnySetter
Your Model Mybean.class should look something like this and it should work
import java.util.HashMap;
import java.util.Map;
import com.fasterxml.jackson.annotation.JsonAnyGetter;
import com.fasterxml.jackson.annotation.JsonAnySetter;
public class MyBean {
private CopyMetadata copy;
private String known;
private Map<String, Object> others = new HashMap<>();
public CopyMetadata getCopy() {
return copy;
}
public void setCopy(CopyMetadata copy) {
this.copy = copy;
}
public String getKnown() {
return known;
}
public void setKnown(String known) {
this.known = known;
}
public Map<String, Object> getOthers() {
return others;
}
public void setOthers(Map<String, Object> others) {
this.others = others;
}
@JsonAnyGetter
public Map<String, Object> getUnknownFields() {
return others;
}
@JsonAnySetter
public void setUnknownFields(String name, Object value) {
others.put(name, value);
}
}
