你好我有Json String，它的深度达到N级，跟随我的Json String

我的结构就像发布 - ＆gt;儿童 - ＆gt;儿童 - ＆gt;所以在子孩子的水平上是N ..但是我需要它们直到2级释放 - ＆gt;孩子们就是这样。 我希望他们使用Gson映射到我的java类我的Java类结构将是这样的
Class release{
String id ;
String name ;
String start_date;
List<Children> children ;
}
Class Children{
String id ;
String name ;
String start_date;
}
答案 0 :(得分：0)
你可以像这样达到n级或2级，这里是适用于你json格式的Java类
public class BaseModel {
private String id;
private String name;
private String start_date;
private boolean can_modify;
private String due_date;
private String velocity_start_date;
private String Stringrelease_notes;
private String status;
private boolean is_active;
private String release_type;
// here getter/setter
}
发布课程
public class Release extends BaseModel {
private List<Children> children;
private Capacity capacity;
private Parent parent;
public List<Children> getChildren() { return children; }
public void setChildren(List<Children> children) { this.children = children;}
public Capacity getCapacity() { return capacity;}
public void setCapacity(Capacity capacity) { this.capacity = capacity;}
@Override
public String toString() {
return "Release [capacity=" + capacity + ", parent=" + parent
+ ", getChildren()=" + getChildren() + ", getCapacity()="
+ getCapacity() + "]";
}
}
儿童班
public class Children extends BaseModel {
private List<Children> children;
private Capacity capacity;
private Parent parent;
public List<Children> getChildren() {return children;}
public void setChildren(List<Children> children) {this.children = children;}
@Override
public String toString() {
return "Children [capacity=" + capacity + ", parent=" + parent
+ ", getChildren()=" + getChildren() + "]";
}
}
父类
public class Parent {
private int id;
@Override
public String toString() { return "Parent [id=" + id + "]"; }
}
容量等级
public class Capacity {
private int duration;
private TimeUnit time_unit;
@Override
public String toString() {
return "ChildCapacity [duration=" + duration + ", time_unit="+ time_unit + "]";
}
}
只需致电
即可Gson gson = new Gson();
Release release =gson.fromJson(Your_Json_String, Release.class);
release.getCapacity();
release.getParent();
release.getChildren(); // return main array below
// go inside for nested level lik as
release.getChildren().get(0).getChildren(); // return child array.
release.getChildren().get(0).getChildren().get(0).getChildren();// return nested child array of above level
如果你想要检索父母的特定孩子，那么你需要在给json脱盐后实现你自己的递归。
享受！ ：）
