アノテーションなしで特定の Gson フィールド プロパティを除外するにはどうすればよいですか?

public class FieldExclusionStrategy implements ExclusionStrategy {

    private List<String> excludedProperties;

    public FieldExclusionStrategy(List<String> excludedProperties) {
        this.excludedProperties = excludedProperties;
    }

    @Override
    public boolean shouldSkipField(FieldAttributes fieldAttributes) {
        String fieldName = fieldAttributes.getName();
        for (String excludedProperty : excludedProperties) {
            if (fieldName.startsWith(excludedProperty)) {
                return true;
            }
        }
        return false;
    }

    @Override
    public boolean shouldSkipClass(Class<?> clazz) {
        return false;
    }
}

Gson gson = new GsonBuilder()
                .setExclusionStrategies(new FieldExclusionStrategy(Arrays.asList("country.name")))
                .create();
