I'm struggling with an issue of WebClient post request I'm trying to use a jsonString as an input (which uses a RequestDto)
Here is my RequestDto
class PaymentStartReqestDto implements Serializable{
@JsonProperty("POSKey")
String pOSKey
@JsonProperty("PaymentType")
String paymentType
@JsonProperty("PaymentWindow")
String paymentWindow
@JsonProperty("GuestCheckout")
String guestCheckout
@JsonProperty("FundingSources")
List<String> fundingSources
//TODO Ezt a bolt fogja generalni a hivas szambol valahogy
@JsonProperty("PaymentRequestId")
String paymentRequestId
//generált a shop által
@JsonProperty("OrderNumber")
String orderNumber
@JsonProperty("PayerHint") //TODO EZ AZ EMAIL CIM LESZ
String payerHint
@JsonProperty("ShippingAddress")
ShippingAddressDto shippingAddress
@JsonProperty("RedirectUrl")
String redirectUrl
@JsonProperty("CallbackUrl")
String callbackUrl
@JsonProperty("Locale")
String locale
@JsonProperty("Currency")
String currency
@JsonProperty("Transactions")
List<PaymentTransactionDto> transactions
static class ShippingAddressDto implements Serializable{
@JsonProperty("Country")
String country
@JsonProperty("City")
String city
@JsonProperty("Zip")
String zip
@JsonProperty("Street")
String street
@JsonProperty("Street2")
String street2
@JsonProperty("FullName")
String fullName
@JsonProperty("Phone")
String phone
}
static class PaymentTransactionDto implements Serializable{
@JsonProperty("POSTransactionId")
String pOSTransactionId
@JsonProperty("Payee")
String payee
@JsonProperty("Total")
String total
@JsonProperty("Items")
List<Item> items
}
static class Item implements Serializable {
Item(String name, String description, int quantity, String unit, int unitPrice, int itemTotal, String sKU) {
this.name = name
this.description = description
this.quantity = quantity
this.unit = unit
this.unitPrice = unitPrice
this.itemTotal = itemTotal
this.sKU = sKU
}
@JsonProperty("Name")
String name
@JsonProperty("Description")
String description
@JsonProperty("Quantity")
int quantity
@JsonProperty("Unit")
String unit
@JsonProperty("UnitPrice")
int unitPrice
@JsonProperty("ItemTotal")
int itemTotal
@JsonProperty("SKU")
String sKU
}
}
here is my ResponseDto
class PaymentStartResponseDto implements Serializable{
@JsonProperty("PaymentId")
String paymentId
@JsonProperty("PaymentRequestId")
String paymentRequestId
@JsonProperty("Status")
String status
@JsonProperty("QRUrl")
String qRUrl
@JsonProperty("Transactions")
List<ProcessedTransactionDto> processedTransactions
@JsonProperty("GatewayUrl")
String gatewayUrl
@JsonProperty("CallbackUrl")

String pOSTransactionId
@JsonProperty("TransactionId")
String transactionId
@JsonProperty("Status")
String status
@JsonProperty("Currency")
String currency
@JsonProperty("TransactionTime")
String transactionTime
}
}
this is the method where I create the DTO
PaymentStartReqestDto requestDto = new PaymentStartReqestDto()
requestDto.pOSKey = ApplicationProperties.instance.barionPosKey
requestDto.paymentType = "Immediate"
requestDto.paymentWindow = "00:30:00"
requestDto.guestCheckout = "True"
requestDto.fundingSources = Arrays.asList("All")
requestDto.paymentRequestId = "payment-26"
requestDto.orderNumber = "order-26"
requestDto.payerHint = "[email protected]"
PaymentStartReqestDto.ShippingAddressDto shippingAddressDto = new PaymentStartReqestDto.ShippingAddressDto()
shippingAddressDto.country = "HU"
shippingAddressDto.city = "Budapest"
shippingAddressDto.zip = "1038"
shippingAddressDto.street = "Vasút sor 4"
shippingAddressDto.street2 =""
shippingAddressDto.fullName = "Zsíros Bence"
shippingAddressDto.phone = "06707777777"
requestDto.shippingAddress = shippingAddressDto
requestDto.redirectUrl = "https://google.com"
requestDto.callbackUrl = "https//google.com"
requestDto.locale = "hu-HU"
requestDto.currency = "HUF"
PaymentStartReqestDto.PaymentTransactionDto transactionDto = new PaymentStartReqestDto.PaymentTransactionDto()
transactionDto.pOSTransactionId = "tr-26"
transactionDto.payee = "[email protected]"
transactionDto.total = "400"
PaymentStartReqestDto.Item item = new PaymentStartReqestDto.Item("Digital Camera", "Canon D500", 1, "pcs", 300,300, "cn-d500-fxc3")
transactionDto.items = new ArrayList<PaymentStartReqestDto.Item>()
transactionDto.items.add(item)
requestDto.transactions = new ArrayList<PaymentStartReqestDto.PaymentTransactionDto>()
requestDto.transactions.add(transactionDto)
return requestDto
}
And here is my code
WebClient barionClient = WebClient.create(ApplicationProperties.instance.barionBaseUrl)
PaymentStartReqestDto reqestDto = createPaymentRequestData()
String requestJson = mapper.writerWithDefaultPrettyPrinter().writeValueAsString(reqestDto)
String goodRequestJson = "{\n" +
" \"POSKey\":\"b8f0189637004869aba00e565ce1ed02\",\n" +
" \"PaymentType\":\"Immediate\",\n" +
" \"PaymentWindow\":\"00:30:00\",\n" +
" \"GuestCheckout\":\"True\",\n" +
" \"FundingSources\":[\n" +
" \"All\"\n" +
" ],\n" +
" \"PaymentRequestId\":\"payment-26\",\n" +
" \"OrderNumber\":\"order-26\",\n" +
" \"PayerHint\":\"[email protected]\",\n" +
" \"ShippingAddress\":{\n" +
" \"Country\":\"HU\",\n" +
" \"City\":\"Budapest\",\n" +
" \"Zip\":\"1038\",\n" +
" \"Street\":\"Vasút sor 4\",\n" +
" \"Street2\":\"\",\n" +
" \"FullName\":\"John Doe\",\n" +
" \"Phone\":\"06707777777\"\n" +
" },\n" +
" \"RedirectUrl\":\"https://google.com\",\n" +
" \"CallbackUrl\":\"https://googlecm\",\n" +
" \"Locale\":\"hu-HU\",\n" +
" \"Currency\":\"HUF\",\n" +
" \"Transactions\":[\n" +
" {\n" +
" \"POSTransactionId\":\"tr-25\",\n" +
" \"Payee\":\"[email protected]\",\n" +
" \"Total\":400,\n" +
" \"Items\":[\n" +
" {\n" +
" \"Name\":\"Digital Camera\",\n" +
" \"Description\":\" " + "CANON-500" + " \",\n" +
" \"Quantity\":1,\n" +
" \"Unit\":\"pcs\",\n" +
" \"UnitPrice\":300,\n" +
" \"ItemTotal\":300,\n" +
" \"SKU\":\"cn-d500-fxc3\"\n" +
" }\n" +
" ]\n" +
" }\n" +
" ]\n" +
"}"
PaymentStartResponseDto response = barionClient
.post()
.uri(ApplicationProperties.instance.barionPaymentStartUri)
.contentType(MediaType.APPLICATION_JSON)
.accept(MediaType.APPLICATION_JSON)
.bodyValue(requestJson)
.retrieve()
.bodyToMono(PaymentStartResponseDto.class)
.block()
If i use the goodRequestJson I can map the result to the PaymentStartResponseDto, But if I'm using the requestJson - which comes from the objectMapper (which seems to be similar to goodRequestJson)
i got
Suppressed: java.lang.Exception: #block terminated with an error
at reactor.core.publisher.BlockingSingleSubscriber.blockingGet(BlockingSingleSubscriber.java:99) ~[reactor-core-3.4.12.jar:3.4.12]
at reactor.core.publisher.Mono.block(Mono.java:1707) ~[reactor-core-3.4.12.jar:3.4.12]
if I remove the block call, I got

could anyone help?
Thanks, Regards
