We are using the DynamoDB Enhanced Client from the latest Java AWS SDK to interact with our DynamoDB

@Builder(toBuilder = true)
@Setter
@NoArgsConstructor
@AllArgsConstructor
@DynamoDbBean
@ToString
@EqualsAndHashCode
public class ModificationsDAO {
    @Getter(onMethod = @__({@DynamoDbPartitionKey, @DynamoDbAttribute("id")}))
    private String id;

    @Getter(onMethod = @__({@DynamoDbAttribute("values")}))
    private GenericPair<?> values;
}

Where the GenericPair class looks like this –

class GenericPair<T> {
    T oldValue;
    T newValue;
    Class< T > clazz;
} // Omitted getters, setters and constructors for brevity.

How do I serialize and deserialize this class while storing and reading from DynamoDB table?

I have gone through this Control Attribute Conversion documentation but not sure how to do this for this Generic type. Any help would be greatly appreciated.
