Java-字段名称的别名

问题描述

说我有一个对象:

Object A
    String field1 = "abc";
    String field2 = "xyz";

上面的json是:

{
    "ObjectA": {
      "field1": "abc",
      "field2": "xyz"
    }
}

在发送json之前，我试图为字段名称创建新的ID.例如. "field1"将被称为"f1"，"field2"将被称为"f2".因此预期的输出json如下所示:

I was trying to create a new id for the field names before sending the json. E.g. "field1" to be called "f1" and "field2" to be called "f2". So the intended output json is shown below:

{
    "ObjectA": {
      "f1": "abc",
      "f2": "xyz"
    }
}

我不确定该怎么做.以上可以干净的方式完成吗?感谢您的帮助和指导.

I am not sure how to do this. Can the above be done in a clean way? Thanks for your help and pointers.

我正在使用gson.

推荐答案

在字段中使用注释@SerializedName("name").像这样:

Use the annotation @SerializedName("name") on your fields. Like this:

Object A
@SerializedName("f1")
String field1 = "abc";
@SerializedName("f2")
String field2 = "xyz";

请参见 https://google.github.io /gson/apidocs/com/google/gson/annotations/SerializedName.html .
