Ignoring new fields on JSON objects using Jackson

If you want to ignore new fields on JSON objects when using Jackson, you can use the @JsonIgnoreProperties annotation on your Java object. This annotation allows you to specify a list of field names to ignore, or you can use the ignoreUnknown property to ignore all unknown properties.

For example:

@JsonIgnoreProperties(ignoreUnknown = true)
public class MyObject {
    // class definition goes here
}

Alternatively, you can configure the ObjectMapper to ignore unknown properties globally:

ObjectMapper mapper = new ObjectMapper();
mapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);

This will cause the ObjectMapper to ignore any unknown properties when deserializing JSON to Java objects.
