我们可以在领域使用gson模型吗？当我尝试显示构建时间错误时

Question

当我尝试在显示错误时构建或运行项目时，GSON模型意味着Wich我将在Web服务响应中使用，而我正在使用领域数据库FirstTime，因此

错误指出，您不能将对象类型作为字段

引用自https://realm.io/docs/java/latest/#field-types：

Realm支持以下字段类型：布尔值，字节，短型，整数，长型，浮点型，双精度型，字符串，日期和字节[]。整数类型byte，short，int和long在Realm中都映射到相同的类型（实际上是long）。此外，还支持RealmObject和RealmList的子类来建立关系模型。

装箱的布尔值，字节，短型，整数，长型，浮点型和双精度型也可以在模型类中使用。使用这些类型，可以将字段的值设置为null。

您需要将字段声明为这些类型之一，但是，如果您可以对允许使用允许的类型进行序列化/反序列化，则可以在getters / setter中执行此操作，并将具有所需对象类型的API展示给用户。

您还可以使用@Ingnore批注，这样就不会考虑到该特定字段，并且可以在创建对象时自行填充该字段，但这是一种不太安全的方法，因为每次工作时都需要记住这一事实用它。
