Could you please assist me? I am encountering the following exception when trying to cast a JSON string to a custom Java object.
org.codehaus.jackson.map.exc.UnrecognizedPropertyException: Unrecognized field "acknowledgedby" (Class com.xchange.model.XchangeOutboundMessage), not marked as ignorable
at [Source: java.io.StringReader@3452296e; line: 1, column: 34] (through reference chain: com.xchange.model.XchangeOutboundMessage["acknowledgedby"])
I have come across several links on StackOverflow recommending the @JsonIgnore annotation for the model's fields, but I cannot ignore this particular field.
public List getOutBoundMessageList(){
List list=new ArrayList();
ObjectMapper mapper = new ObjectMapper();
XchangeOutboundMessage xchangeOutboundMessage=null;
String json1=null;
try {
cluster = Cluster.builder().addContactPoint(contactPoints).build();
session = cluster.connect(keySpaceName);
cassandraOps = new CassandraTemplate(session);
String queryString="Select JSON * from XchangeOutboundMessage";
ResultSet result = session.execute(queryString);
int i=0;
String json1=null;
for(Row row:result) {
json1 = row.getString(i);
xchangeOutboundMessage = mapper.readValue(json1, XchangeOutboundMessage.class);
list.add(xchangeOutboundMessage);
i++;
}
} catch (Exception e) {
e.printStackTrace();
}
return list;
}
}
The error is occurring in the model class field and its corresponding getter and setter methods.
private String acknowledgedBy;
public String getAcknowledgedBy() {
return acknowledgedBy;
}
public void setAcknowledgedBy(String acknowledgedBy) {
this.acknowledgedBy = acknowledgedBy;
}
