Dear All;
My android application comminicate with a .net rest service. This .net rest service use json.net library.
My Rest Method result is
{"$id": "2",
"ID": 1,
"Code": "K1M1",
"Name": "Masa 1",
"Capacity": 4,
"Floor": {
"$id": "3",
"ID": 1,
"Code": "K1",
"Name": "Kat 1",
"Tables": [
{
"$ref": "2"
},
{
"$id": "4",
"ID": 2,
"Code": "K1M2",
"Name": "Masa 2",
"Capacity": 4,
"Floor": {
"$ref": "3"
},
"TableOrder": null,
"PersistQuery": {
"$id": "5"
},
"PersistDataSourceQuery": {
"$id": "6"
}
},
{
"$id": "7",
"ID": 3,
"Code": "K1M3",
"Name": "Masa 3",
"Capacity": 2,
"Floor": {
"$ref": "3"
},
"TableOrder": null,
"PersistQuery": {
"$id": "8"
},
"PersistDataSourceQuery": {
"$id": "9"
}
}
],
"PersistQuery": {
"$id": "10"
},
"PersistDataSourceQuery": {
"$id": "11"
}
}
}
My Gson configuration
gson = new GsonBuilder()
//.registerTypeAdapter(Id.class, new IdTypeAdapter())
.enableComplexMapKeySerialization()
.serializeNulls()
.setDateFormat("dd.MM.yyyy HH:mm:ss:SSS zzz")
.setFieldNamingPolicy(FieldNamingPolicy.UPPER_CAMEL_CASE)
.create()
My Objects
public class Table {
private long ID;
private String Code;
private String Name;
private int Capacity;
private Floor Floor;
private TableOrder TableOrder;
public Table() {
// TODO Auto-generated constructor stub
}
public int getCapacity() {
return Capacity;
}
public String getCode() {
return Code;
}
public Floor getFloor() {
return Floor;
}
public long getID() {
return ID;
}
public String getName() {
return Name;
}
public TableOrder getTableOrder() {
return TableOrder;
}
public void setCapacity(int value) {
Capacity = value;
}
public void setCode(String value) {
Code = value;
}
public void setFloor(Floor value) {
Floor = value;
}
public void setID(long value) {
ID = value;
}
public void setName(String value) {
Name = value;
}
public void setTableOrder(TableOrder value) {
TableOrder = value;
}
}
public class Floor {
private long ID;
private String Code;
private String Name;
public java.util.List<Table> Tables;
public Floor() {
// TODO Auto-generated constructor stub
}
public String getCode() {
return Code;
}
public long getID() {
return ID;
}
public String getName() {
return Name;
}
public java.util.List<Table> getTables() {
return Tables;
}
public void setCode(String value) {
Code = value;
}
public void setID(long value) {
ID = value;
}
public void setName(String value) {
Name = value;
}
public void setTables(java.util.List<Table> value) {
Tables = value;
}
}
My Deserialization List<Table> . Rest service result 3 table object but my first object is true deserialization but other 2 object property is null. Becouse bi directional references ($ref) gson dont set already serialized objects.
How can i resolve this problem.
Best regards
