Question

我有一个包含13个字段的JSON。但是我在Java中创建了一个具有15个字段的模型。因为我想要一个完整的模型，将来它将在服务器端增加这些字段。这样做是错误的？我的json是：

{
    "CMBL009001": "010001",
    "NMBL009002": 0,
    "CMBL009003": "",
    "CMBL009004": "",
    "CMBL009005": "",
    "CMBL009006": "",
    "NMBL009007": 0,
    "BMBL009008": 0,
    "NMBL009009": 0,
    "CMBL009010": "ADMIN",
    "CMBL009011": "",
    "NMBL009012": 2,
    "NMBL009013": 1
}

我的班级是：

Answer 1

是的，您可以在模型中包含额外的字段，但是如果服务器未提供这些字段的值，则这些额外的字段将使用默认值初始化。

Answer 2

如果使用的是GSON，则必须将字段/成员声明标记为@Expose才能进行解析。使用GsonBuilder().excludeFieldsWithoutExposeAnnotation().create()

添加其他字段，请勿序列化这些字段。

是否有可能创建一个比json更多项目的模型？
