I am trying to convert a Json to a Java object.I have a String named 'result' and I want to Convert it into a Java Object whose class is TransferRecord.java
This is a part of the string I use as the input.
{
"TransferRecord": {
"TransferId": {
"TransferRef": "string",
"DistributorRef": "string"
},
"SkuCode": "string",
"Price": {
"CustomerFee": 0,
"DistributorFee": 0,
"ReceiveValue": 0,
"ReceiveCurrencyIso": "string",
"ReceiveValueExcludingTax": 0,
"TaxRate": 0,
"TaxName": "string",
"TaxCalculation": "string",
"SendValue": 0,
"SendCurrencyIso": "string"
},
"CommissionApplied": 0,
"StartedUtc": "2019-01-31T10:10:20.527Z",
"CompletedUtc": "2019-01-31T10:10:20.527Z",
"ProcessingState": "string",
"ReceiptText": "string",
"ReceiptParams": {},
"AccountNumber": "string"
},
"ResultCode": 0,
"ErrorCodes": [
{
"Code": "string",
"Context": "string"
}
]
}
This is the TransferRecord class. I checked the json mapping and they are perfectly identical.Note that there are more fields available in class but I just pasted a part of it.The number of properties in input string and the java class are same.
public class TransferRecord {
@JsonProperty("TransferId")
private TransferId transferId = null;
@JsonProperty("SkuCode")
private String skuCode = null;
@JsonProperty("Price")
private Price price = null;
@JsonProperty("CommissionApplied")
private BigDecimal commissionApplied = null;
@JsonProperty("StartedUtc")
private Date startedUtc = null;
@JsonProperty("CompletedUtc")
private Date completedUtc = null;
@JsonProperty("ProcessingState")
private String processingState = null;
@JsonProperty("ReceiptText")
private String receiptText = null;
@JsonProperty("ReceiptParams")
private Map<String, String> receiptParams = null;
@JsonProperty("AccountNumber")
private String accountNumber = null;
public TransferRecord transferId(TransferId transferId) {
this.transferId = transferId;
return this;
}
}
Following is my code which I used for the conversion.Note that these three pieces of code would serve the same purpose and I tried them separately.
ObjectMapper mapper = new ObjectMapper();
//1 TransferRecord objTransRecord = mapper.readValue(result, TransferRecord.class);
//2 TransferRecord objTransRecord = mapper.readerWithView(TransferRecord.class).forType(TransferRecord.class).readValue(result);
//3 TransferRecord objTransRecord = mapper.readerFor(TransferRecord.class).readValue(result);
Problem is when I try to create the object,every value is set to null in all three approaches even though there are corresponding data available in the String. Can someone please point out what I am doing wrong here?
Thanks in advance. :)
This it NOT TransferRecord class. Your json fetch class with 3 fields:
public class Something {
@JsonProperty("TransferRecord")
private TransferRecord transferRecord;
@JsonProperty("ResultCode")
private int resultCode;
@JsonProperty("ErrorCodes")
private List<ErrorCode> errorCodes;
}
