正如您所看到的，"list": {}有很多项，但它是一个数组，它包含对象。所以当我尝试使用http://www.jsonschema2pojo.org生成POJO时，我得到以每个项目的ID命名的POJOS：

包含项目的List POJO创建为：

import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;
public class List {
@SerializedName("1015284226")
@Expose
private model._1015284226 _1015284226;
/**
* No args constructor for use in serialization
*
*/
public List() {
}
/**
*
* @param _1015284226
*/
public List(model._1015284226 _1015284226) {
super();
this._1015284226 = _1015284226;
}
public model._1015284226 get1015284226() {
return _1015284226;
}
public void set1015284226(model._1015284226 _1015284226) {
this._1015284226 = _1015284226;
}
}
当我尝试解析JSON时，这显然给了我一些问题
我正在使用改装2。
我在想我应该重构List POJO，因此它包含一个项目的ArrayList，但是不想过多地为我自动生成的内容做错。
答案 0 :(得分：0)
你可以像这样手动完成。
JSONObject jsonObj = new JSONObject(json);
JSONObject lists= jsonObj.getJSONObject("list");
Iterator x = lists.keys();
JSONArray jsonArray = new JSONArray();
while (x.hasNext()){
String key = (String) x.next();
jsonArray.put(lists.get(key));
}
jsonArray是你的列表。
之后，您可以将JSON解析为object。
