如何使用继承序列化构建器类？

Question

我面临一个生成器类继承的序列化问题。如下所示：

@Getter
@Setter
public class NumberRuleConfig extends BaseRuleConfig{
    private Double min;
    private Double max;
    private Double step;
    private Map<String, Object> defaultValue;

    @Builder
    public NumberRuleConfig(Boolean enabled,
                            Boolean editable,
                            Double min,
                            Double max,
                            Double step,
                            Map<String, Object> defaultValue) {
        super(enabled, editable);
        this.min = min;
        this.max = max;
        this.step = step;
        this.defaultValue = defaultValue;
    }

    public NumberRuleConfig(Boolean enabled, Boolean editable) {
        super(enabled, editable);
    }
}

基类：

@Getter
@AllArgsConstructor
public class BaseRuleConfig {
    public Boolean enabled;
    public Boolean editable;

    public BaseRuleConfig() {
    }
}

我看到以下例外：

com.fasterxml.jackson.databind.exc.InvalidDefinitionException: No serializer found for class com.example.NumberRuleConfig$NumberRuleConfigBuilder and no properties discovered to create BeanSerializer (to avoid exception, disable SerializationFeature.FAIL_ON_EMPTY_BEANS) (through reference chain: java.util.ImmutableCollections$MapN["ruleSetDefinitions"]->com.example.RuleDefinitions["constraints"]->java.util.ArrayList[7]->com.example.NumberRule["config"])
    at com.fasterxml.jackson.databind.exc.InvalidDefinitionException.from(InvalidDefinitionException.java:77)
    at com.fasterxml.jackson.databind.SerializerProvider.reportBadDefinition(SerializerProvider.java:1277)
    at com.fasterxml.jackson.databind.DatabindContext.reportBadDefinition(DatabindContext.java:400)
    at com.fasterxml.jackson.databind.ser.impl.UnknownSerializer.failForEmpty(UnknownSerializer.java:71)
    at com.fasterxml.jackson.databind.ser.impl.UnknownSerializer.serialize(UnknownSerializer.java:33)

有人知道如何避免这个问题吗？

以下注释可以正常工作：
