我使用Order对象将数据推送到Firebase，问题是我想要每个子名称的首字母大写.我将属性定义为投诉"，但在Firebase中，该属性仍显示为投诉"，我不知道该怎么做.

I push data to Firebase using Order object, the question is I want the first letter of every child name capital. I defined the property like "Complain" but in Firebase it still shows as "complain", I dont know how to make it.

Firebase的当前结构:

The current structure of the Firebase:

我想要的结构:

我这样定义属性:

@Data public class Order implements Serializable { @SerializedName("Complain") private String Complain; public Order() { Complain = ""; } public String getComplain() { return Complain; } public void setComplain(String complain) { Complain = complain; } }

我这样将数据推送到Firebase:

I push data to Firebase like this:

Map<String, Object> map = new HashMap<>(); map.put(orderSavePath, order); reference.updateChildren(map).addOnCompleteListener(listener);

推荐答案

Firebase JSON序列化名称由注释PropertyName .

The Firebase JSON serialization name is controlled by the annotation PropertyName.

public class Order implements Serializable { private String Complain; public Order() { Complain = ""; } @PropertyName("Complain") public String getComplain() { return Complain; } @PropertyName("Complain") public void setComplain(String complain) { Complain = complain; } }

注释必须同时在getter和setter上.或者，您可以只使用公共字段并将类简化为:

The annotation needs to be on both the getter and the setter. Alternatively you can just use public fields and reduce the class to:

public class Order { @PropertyName("Complain") public String Complain; }
