假设我有这个News和这个嵌套的Comment数据结构:

public class News {
  public int id;
  public int[] commentIds; //only top level comments
  public News(int id, int[] commentIds) {

    this.commentIds = commentIds;
  }
}

public class Comment {
  public int id;
  public int parentId; //ID of parent News or parent comment
  public int[] childIds;
  public Comment(int id, int parentId, int[] childIds) {
    this.id = id;
    this.parentId = parentId;
    this.childIds = childIds;
  }
}

并假设我有这个API端点:
