为自定义序列化bean生成json-schema

标签: json jackson jsonschema fasterxml jackson-modules

我使用FasterXML json-schema generator从我的POJO构建json-schema。 一切顺利,直到我的POJO使用自定义json序列化。在我的情况下,我有一个类型为org.joda.Money的字段,我用相应的joda模块序列化它。 bean像

一样序列化
{
  "amount": "...",
  "currency": "..."
}

但它的架构如下所示:

{
  "type" : "object",
  "id" : "urn:jsonschema:org:joda:money:Money",
  "properties" : {
    "amount" : {
      "type" : "number"
    },
    "amountMinorLong" : {
      "type" : "integer"
    },
    "scale" : {
      "type" : "integer"
    },
    "minorPart" : {
      "type" : "integer"
    },
    "positive" : {
      "type" : "boolean"
    },
    "amountMajor" : {
      "type" : "number"
    },
    "amountMinor" : {
      "type" : "number"
    },
    "amountMinorInt" : {
      "type" : "integer"
    },
    "positiveOrZero" : {
      "type" : "boolean"
    },
    "zero" : {
      "type" : "boolean"
    },
    "negative" : {
      "type" : "boolean"
    },
    "amountMajorLong" : {
      "type" : "integer"
    },
    "amountMajorInt" : {
      "type" : "integer"
    },
    "negativeOrZero" : {
      "type" : "boolean"
    },
    "currencyUnit" : {
      "type" : "object",
      "id" : "urn:jsonschema:org:joda:money:CurrencyUnit",
      "properties" : {
        "symbol" : {
          "type" : "string"
        },
        "numeric3Code" : {
          "type" : "string"
        },
        "countryCodes" : {
          "type" : "array",
          "items" : {
            "type" : "string"
          }
        },
        "code" : {
          "type" : "string"
        },
        "decimalPlaces" : {
          "type" : "integer"
        },
        "defaultFractionDigits" : {
          "type" : "integer"
        },
        "currencyCode" : {
          "type" : "string"
        },
        "pseudoCurrency" : {
          "type" : "boolean"
        },
        "numericCode" : {
          "type" : "integer"
        }
      }
    }
  }
}

有没有办法自定义生成的架构?

我认为jackson-datatype-joda不支持Joda Money数据类型。

你可以尝试我自己的模块。我不确定它是否适合使用模式生成,但它适用于序列化/反序列化。

public class JodaMoneyModule extends SimpleModule {

    @Override
    public void setupModule(final SetupContext context) {
        final SimpleSerializers serializers = new SimpleSerializers();
        serializers.addSerializer(Money.class, new JodaMoneySerializer());
        context.addSerializers(serializers);
        final SimpleDeserializers deserializers = new SimpleDeserializers();
        deserializers.addDeserializer(Money.class, new JodaMoneyDeserializer());
        context.addDeserializers(deserializers);
    }

    private class JodaMoneySerializer extends JsonSerializer<Money> {
        @Override
        public void serialize(
                final Money value,
                final JsonGenerator gen,
                final SerializerProvider serializers)
                throws IOException {
            gen.writeString(value == null ? null : value.toString());
        }
    }

    private class JodaMoneyDeserializer extends JsonDeserializer<Money> {

        @Override
        public Money deserialize(final JsonParser p, final DeserializationContext ctxt)
                throws IOException {
            final String value = p.getValueAsString();
            return value == null ? null : Money.parse(value);
        }
    }
}
