I'm trying to transform the following JSON into a java Object.
{
"Data":[
{
"AccountId":"2009852923",
"Currency":"EUR",
"Nickname":"SA 01",
"Account":{
"SchemeName":"BBAN",
"Name":"SA 01",
"Identification":"2009852923"
},
"Servicer":{
"SchemeName":"BICFI",
"Identification":"FNBSZAJJ"
}
},
{
"AccountId":"1028232942",
"Currency":"EUR",
"Nickname":"FNBCREDIT",
"Account":{
"SchemeName":"BBAN",
"Name":"FNBCREDIT",
"Identification":"1028232942"
},
"Servicer":{
"SchemeName":"BICFI",
"Identification":"FNBSZAJJ"
}
}
],
"Links":{
"self":"http://localhost:3000/api/open-banking/accounts/1009427721/transactions"
},
"Meta":{
"total-pages":1
}
}
Using the following DTO (for brevity, the referenced classes haven't been posted).
public class TransactionDTO {
private Data[] data;
private Links links;
private Meta meta;
public Data[] getData () { return data; }
public void setData (Data[] data) { this.data = data; }
public Links getLinks () { return links; }
public void setLinks (Links links) { this.links = links; }
public Meta getMeta () { return meta; }
public void setMeta (Meta meta) { this.meta = meta; }
}
The code to transform the DTO to a Java object being:
private TransactionDTO marshall(String accountTransactionsJSON) {
ObjectMapper objectMapper = new ObjectMapper();
TransactionDTO transactionDTO = null;
try {
transactionDTO = objectMapper.readValue(accountTransactionsJSON, TransactionDTO.class);
} catch (IOException e) {
e.printStackTrace();
}
return transactionDTO;
}
I'm getting this error:
com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException: Unrecognized field "Data" (class xxx.dto.TransactionDTO), not marked as ignorable (3 known properties: "links", "data", "meta"])
at [Source: java.io.StringReader@48f43b70; line: 2, column: 11] (through reference chain: xxx.dto.TransactionDTO["Data"])
I tried different approach to solve this issue such as:
objectMapper.enable(SerializationFeature.WRAP_ROOT_VALUE);
objectMapper.configure(DeserializationFeature.ACCEPT_SINGLE_VALUE_AS_ARRAY, true);
objectMapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
As well as:
@JsonRootName(value = "data")
But I either get the same problem, or no problems, but the TransactionDTO
containing null
values only.
I guess the problem is the Data
field, but I don't know how to fix this problem (the solutions here don't work for me neither).
Questions
I solved a similar problem using this aproach
ObjectMapper objectMapper = new ObjectMapper();
objectMapper.disable(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES);
