GraphQL 扩展在 graphql-java 中创建 com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException

Question

我们正在使用 GraphQL 中的 Shopify Admin API 来创建应用程序。我们这里是基于这个例子开发的——https://github.com/graphql-java-generator/GraphQL-Forum-Maven-Tutorial-client

我们使用 apollo (nodejs) 从 Shopify 下载了架构，POJO 文件是自动生成的。我们能够成功请求 Shopify Storefront API，但 Admin API 有一个额外的字段“extensions”，这会导致反序列化失败。

我们收到的错误：

Exception in thread "main" javax.ws.rs.client.ResponseProcessingException:

我已尝试将@JsonIgnoreProperties(ignoreUnknown = true) 添加到 POJO 中，并将反序列化功能添加到对象映射器中：

ObjectMapper o = new ObjectMapper();
o.disable(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES);
o.disable(DeserializationFeature.FAIL_ON_IGNORED_PROPERTIES);
o.disable(DeserializationFeature.FAIL_ON_INVALID_SUBTYPE);
o.disable(DeserializationFeature.FAIL_ON_MISSING_CREATOR_PROPERTIES);
o.disable(DeserializationFeature.FAIL_ON_MISSING_EXTERNAL_TYPE_ID_PROPERTY);
o.disable(DeserializationFeature.FAIL_ON_UNRESOLVED_OBJECT_IDS);

有关如何在反序列化中包含或忽略扩展的任何帮助？谢谢！

Answer 1

此问题已通过最新版本的 graphql-java-generator（1.12.3 及更高版本）解决。感谢开发者，他们还在代码中包含了扩展节点并发布了它。

Answer 2

如果您还没有尝试过，请考虑一下。

o.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
