Jackson 反序列化 json：JSON 字符串中的字段 `form_object_guid` 未在 `DigitalFormGetResponse` 属性中定义

Question

我查询 GET 并获得响应 JSON 字符串，但脱盐抛出 The field

form_object_guid

in the JSON string is not Defined in the

DigitalFormGetResponse

properties，这意味着字段

form_object_guid

在类

DigitalFormGetResponse

中不存在。类

DigitalFormGetResponse

是从 Maven 工件 openapi-generator-maven-plugin 版本 6.6.0 自动生成的，不包含 jersey2 作为库。在我向插件

<additionalModelTypeAnnotations>@com.fasterxml.jackson.annotation.JsonIgnoreProperties(ignoreUnknown = true)</additionalModelTypeAnnotations>

添加注释后，生成的代码显示类

DigitalFormGetResponse

具有 IgnoreProperties 注释，我认为它将忽略检索到的 JSON 字符串中的未知属性。

@com.fasterxml.jackson.annotation.JsonIgnoreProperties(ignoreUnknown = true)
public class DigitalFormGetResponse {

但是，我从自动生成的函数中得到了异常：

我之前的版本在插件中使用了 jersey2，并且可以很好地忽略未知属性。但是，我必须将 jersey2 从插件中移出（因为它不支持 Java16+ 的 PATH 请求），然后这个忽略功能就成为一个问题。

我在 POM 文件中添加了 maven-replacer-plugin 以删除对 validateJsonObject(jsonObj); 的调用；所以不会发生异常。我认为这不是最好的方法，但我必须保留现有逻辑，以免强制进行 JSON 验证。
