在使用Gson解析Json字符串的时候，遇到动态key，如何定义Gson所映射对象？
以下所述方法同样适用于Jackson解析
请看如下Json字符串：
{
"code": 200,
"msg": "成功",
"data": [
{
"id": "section分割模块id",
"tid": "t_competition_schedule_section_1",
"data": {
"source": "json",
"dlist": [
{
"122246": {
"id": 4499,
"hostid": 1416,
"hostname": "曼联",
"hosticon": "http://grocery.pptv.com/lpic/fc3/0f9/893/78688b9029d005028bcfe7d91ce94770.png",
"guestid": 1380,
"guestname": "阿森纳",
"guesticon": "http://grocery.pptv.com/lpic/973/360/548/28af893a78b5d4dc3e0a7af90b9766b4.png",
"hostscore": 1,
"guestscore": 1,
"starttime": 1479558600000,
"endtime": 1479565800000,
"round": "第12轮",
"competitionid": 44,
"competitionname": "英超",
"competitionicon": "http://grocery.pptv.com/lpic/beb/ddd/6e9/acbd2ce6346bae749d76fe1ec0adf4f3.png",
"schedulemark": "英超 第12轮",
"reservetitle": "英超 第12轮 曼联vs阿森纳",
"sectionid": "122246",
"isversus": true,
"hasalarm": false,
"isrecommend": false,
"type": 1
}
}
]
}
}
]
}
122246 这个key是动态的
这个时候，我们可以使用LinkedHashMap<String, Object> dlist；来映射122246所对应的对象。
然后使用SimpleBean bean = new Gson().fromJson(jsonResult, SimpleBean.class)
完整的对象如下(供参考)：
public class SimpleBean {
@SerializedName("code")
private int code;
@SerializedName("msg")
private String msg;
@SerializedName("data")
private List<DataBeanX> data;
public int getCode() {
return code;
}
public void setCode(int code) {
this.code = code;
}
public String getMsg() {
return msg;
}
public void setMsg(String msg) {
this.msg = msg;
}
public List<DataBeanX> getData() {
return data;
}
public void setData(List<DataBeanX> data) {
this.data = data;
}
public static class DataBeanX {
@SerializedName("id")
private String id;
@SerializedName("tid")
private String tid;
@SerializedName("data")
private DataBean data;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getTid() {

}
public void setTid(String tid) {
this.tid = tid;

public DataBean getData() {

}
public void setData(DataBean data) {
this.data = data;
}
public static class DataBean {
