Java - Deserialize nested Json Object to Java Object

Question

I have some probleme to deserialize some nested Json.

The json : Json Link Here To deserialize :

ObjectMapper objectMapper = new ObjectMapper();
ListRandomBixi bixi = objectMapper.readValue(url, ListRandomBixi.class);

And the two classes :

class ListRandomBixi{
@JsonProperty("stations")
ArrayList<RandomBixi> arrayBixi;
@JsonProperty("schemeSuspended")
boolean schemeSuspended;
@JsonProperty("timestamp")
long timeStanp;

@JsonCreator
public ListRandomBixi(@JsonProperty("stations") ArrayList<RandomBixi> arrayBixi, @JsonProperty("schemeSuspended") boolean schemeSuspended, @JsonProperty("timestamp") long timeStanp) {
  this.arrayBixi = arrayBixi;
  this.schemeSuspended = schemeSuspended;
  this.timeStanp = timeStanp;
}
      getters & setters....
}
class RandomBixi {
@JsonProperty("id")
int id;
@JsonProperty("s")
String nom;
@JsonProperty("n")
int idTerminal;
@JsonProperty("st")
int etatStation;
@JsonProperty("b")
boolean bloque;
@JsonProperty("su")
boolean suspendue;
@JsonProperty("m")
boolean hs;
@JsonProperty("lu")
int lu;
@JsonProperty("lc")
int lc;
@JsonProperty("la")
String latitude;
@JsonProperty("lo")
String longitude;
@JsonProperty("da")
int borneDispo;
@JsonProperty("dx")
int dx;
@JsonProperty("ba")
int bixiDispo;
@JsonProperty("bx")
int bx;

  getters ans setters....
}

I'm getting this error : com.fasterxml.jackson.databind.JsonMappingException: Unrecognized Type: [null]

Any suggestions?

Thanks

The value of blabla1 and blabla2 are also text. But you are declare class field is boolean and long . This cause the error. Let's change the type of blabla1 and blabla2 to String
