我已经登录到swaggerhub并生成了一个示例库存api，它是他们模板的一部分。在 codegen options 挑选出来的 spring 作为服务器。勾选 useBeanValidation 复选框。生成代码，测试代码。验证工作正常，除了一件事。我不想在post负载上允许任何附加属性。
注意：openapi规范没有指定“additionalproperties”标志。在我的理解中默认为“假”。我也试图明确指定相同的。但运气不好。添加additionalproperty时不会引发异常。

在post-api上得到了400。

    "name": "ACME Corporation",
    "homePage": "",
    "phone": "408-867-5309"
        }
}

预计400，但没有得到这个有效载荷在岗位上

{
    "id": "7f125802-7840-4ff0-8ddb-7c78c0948983",
    "name": "Widget Adapter",

    "homePage": "",
    "phone": "408-867-5309"
        },
    "newkey" : "newValue"
}

有谁能帮忙吗。。我想完全不允许其他属性，并对这些请求抛出400。。
