Edit 2 : Expected.
For outpout i don't find what is possible to do but if i can transform to a valid json structure will help for exemple :
{
"meta":[
{
"id":"482f75dd-a8e4-4f5c-80f0-85b5a7eeb340",
"value":[
"indéterminé"
]
},
{
"id":"d8cac586-2d64-4fe6-bdf4-91a5bac3541e",
"value":[
"Id system"
]
}
]
}
Thanks for help

Answer 1

In a tLibraryLoad component load the json-simple jar
And import needed librairy (in advanced setting).
import java.io.InputStream;
import java.util.ArrayList;
import java.util.List;
import java.util.stream.Collectors;
import org.json.simple.JSONObject;
import org.json.simple.parser.JSONParser;
In a tJavaFlex component you can work on your data input (called onlyMet bellow)
JSONObject job = new JSONObject();
JSONParser parser = new JSONParser();
try {
//-- Parsing et prepare result
List<JSONObject> resultList = new ArrayList<>();
JSONObject jsonObjects = (JSONObject) parser.parse((String)onlyMet.metas);
jsonObjects.keySet().parallelStream().forEach(entry -> {
JSONObject rjo = new JSONObject();
rjo.put("id", entry);
rjo.put("value", jsonObjects.get(entry));
// System.out.printf("- meta %s : %s \n", entry, jsonObjects.get(entry)); // for debug if needed
resultList.add(rjo);
});
// Outpout the result
onlyOut.metas = resultList.toString();
} catch (final Exception e){
e.printStackTrace();
}
