我有三个类：请求（抽象），RequestCreateContract，RequestUpdateContract。奇怪RequestUpdateContract未能反序列化。我试图将RequestCreateContract代码复制粘贴到RequestUpdateContract中，并且继续失败：只更改了类名和构造函数名称。另一方面，RequestCreateContract没有任何问题。杰克逊多态反序列化失败：不同的类，相同的代码
报道例外：
com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException: Unrecognized field "contract" (class mypackage.net.protocol.request.RequestUpdateContract), not marked as ignorable (one known property: "login"])
这里是代码。 请求（超）

我希望你能重现该问题。这些类是客户端和服务器应用程序之间共享项目的一部分。
