Using PropertyUtils, you can copy onky the non null properties as follows:

    private void copyNonNullProperties(Object destination,
            Object source) {
        try {
            PropertyUtils.describe(source).entrySet().stream()
                    .filter(source -> source.getValue() != null)
                    .filter(source -> !source.getKey().equals("class"))
                    .forEach(source -> {
                        try {
                            PropertyUtils.setProperty(destination, source.getKey(), source.getValue());
                        } catch (Exception e22) {
                            log.error("Error setting properties : {}", e22.getMessage());
                        }
                    });

        } catch (Exception e1) {
            log.error("Error setting properties : {}", e1.getMessage());
        }

    }
