I have a string which I’m supposed to read into an address object.
Now the string I’ll get may contain some extra fields and may not contain some fields which is declared in my Address class.

I’ve already added following annotations on my address class –

@JsonInclude(NON_NULL)
@JsonIgnoreProperties(ignoreUnknown = true)
public class Address {
   private String line1;
   private String line2;
   private String state;
   private String pincode;
......
}

But while deserializing a string like this –
{“street”:”street”,”line1″:”line1″,”line2″:”line2″,”district”:”district”,”pincode”:”pincode”}, getting this error –

java.lang.IllegalArgumentException: Cannot construct instance of `Address` (although at least one Creator exists): no String-argument constructor/factory method to deserialize from String value ('{"street":"street","line1":"line1","line2":"line2","district":"district","pincode":"pincode"}')
 at [Source: UNKNOWN; line: -1, column: -1]

Already added following config to my object mapper –

objectMapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES,
false);
objectMapper.configure(DeserializationFeature.FAIL_ON_MISSING_CREATOR_PROPERTIES,
false);
objectMapper.setSerializationInclusion(JsonInclude.Include.NON_NULL);

Conversion logic –

String addressDetail = info.get("address");
Address address = objectMapper.convertValue(addressDetail, Address.class);
