我在应用程序中将objectbox用作orm，并在一个实体中添加一些额外属性时，由于uid不匹配而获取dbexception。在我浏览文档时，我提到，如果我们在您的实体objectbox中添加或删除属性，就会处理这些更改。但这在我的情况下是不可能的。请看一下我的日志存储、实体和default.json，让我知道解决此问题的可能解决方案。
objectbox版本：v1.2.0

实体
以前我的实体是这样的：
@Entity
public class BookingItem {
private long id;
@Id(assignable = true)
private long priority;
private String date;
private String formattedAddress;
private String orderId;
private String type;
private String title;
private int seatCount;
private String pricePerPerson;
private String time;
private String day;
private String redirectUrl;
private String status;
private long experienceId;
private String shareableUrl;
private ToOne<Image> image;
private ToOne<FeedElement> feedElementToOne;
}
我的default.json如下所示：

现在，在将两个新属性添加到我的实体之后：
@Entity
public class BookingItem {
//region Variables
private long id;
@Id(assignable = true)
private long priority;
private String date;
private String formattedAddress;
private String orderId;
private String type;
private String title;

private String pricePerPerson;
private String totalTax; // 1st new propery

private String time;

private String redirectUrl;

private String shareableUrl;
private ToOne<Image> image;
private ToOne<FeedElement> feedElementToOne;
//endregion
}
