1、解析单个对象
JSON字符串如下
[
{
"formatDate":"2015-10-28",
"date":"2015\u5e7410\u670828\u65e5 \u661f\u671f\u4e09",
"list":[{
"sdate":"2015-10-28",
"time":"08:00",
"type":"\u5e38\u89c4\u8d5b",
"home_team":"\u8001\u9e70",
"home_score":"94",
"visit_team":"\u6d3b\u585e",
"visit_score":"106"
},{
"sdate":"2015-10-28",
"time":"08:00",
"type":"\u5e38\u89c4\u8d5b",
"home_team":"\u516c\u725b",
"home_score":"97",
"visit_team":"\u9a91\u58eb",
"visit_score":"95"
}]
}
]
封装解析的对象
public class NBAMatchs {
/**
* 时间
*/
private String formatDate;
/**
* 赛程时间
*/
private String date;
/**
* 赛事列表
*/
List<NBAMatchBasic> list ;
public String getFormatDate() {
return formatDate;
}
public void setFormatDate(String formatDate) {
this.formatDate = formatDate;
}
public String getDate() {
return date;
}
public void setDate(String date) {
this.date = date;
}
public List<NBAMatchBasic> getList() {
return list;
}
public void setList(List<NBAMatchBasic> list) {
this.list = list;
}
}
实体对象
public class NBAMatchBasic {
private String sdate;
private String time ;
private String home_team;
private String home_score;
private String visit_team;
private String visit_score;
public String getSdate() {
return sdate;
}
public void setSdate(String sdate) {
this.sdate = sdate;
}
public String getTime() {
return time;
}
public void setTime(String time) {
this.time = time;
}
public String getHome_team() {
return home_team;
}
public void setHome_team(String home_team) {
this.home_team = home_team;
}
public String getHome_score() {
return home_score;
}
public void setHome_score(String home_score) {
this.home_score = home_score;
}
public String getVisit_team() {
return visit_team;
}
public void setVisit_team(String visit_team) {
this.visit_team = visit_team;
}
public String getVisit_score() {
return visit_score;
}
public void setVisit_score(String visit_score) {
this.visit_score = visit_score;
}
}
解析代码
public static void main(String[] args) {
String Json = "JSON字符串";
NBAMatchs NBA = new NBAMatchs();
NBA = new Gson().fromJson(Json, NBAMatchs.class);
System.out.println(NBA.getFormatDate());
}
2、解析List集合
Json字符串如下
[
{
"formatDate":"2015-10-28",
"date":"2015\u5e7410\u670828\u65e5 \u661f\u671f\u4e09",
"list":[
{
"sdate":"2015-10-28",
"time":"08:00",
"type":"\u5e38\u89c4\u8d5b",
"home_team":"\u8001\u9e70",
"home_score":"94",
"visit_team":"\u6d3b\u585e",
"visit_score":"106"
},{
"sdate":"2015-10-28",
"time":"08:00",
"type":"\u5e38\u89c4\u8d5b",
"home_team":"\u516c\u725b",
"home_score":"97",
"visit_team":"\u9a91\u58eb",
"visit_score":"95"
}]
},
{
"formatDate":"2015-10-29",
"date":"2015\u5e7410\u670829\u65e5 \u661f\u671f\u56db",
"list":[
{
"sdate":"2015-10-29",
"time":"07:00",
"type":"\u5e38\u89c4\u8d5b",
"home_team":"\u9b54\u672f",
"home_score":"87",
"visit_team":"\u5947\u624d",
"visit_score":"88"
},{
"sdate":"2015-10-29",
"time":"07:30",
"type":"\u5e38\u89c4\u8d5b",
"home_team":"\u51ef\u5c14\u7279\u4eba",
"home_score":"112",
"visit_team":"76\u4eba",
"visit_score":"95"
}]
}
]
解析代码
public static void main(String[] args) {
String NBAMatchJsons ="JSON字符串";
List<NBAMatchs> matchs = new ArrayList<NBAMatchs>();
matchs = new Gson().fromJson(NBAMatchJsons,new TypeToken<ArrayList<NBAMatchs>>() {}.getType());
System.out.println(matchs.size());
}
3、解析map集合
Json字符串
{
'1':
{'id': '1','code': 'bj','name': '北京','map': '39.90403, 116.40752599999996'},
'2':
{'id': '2','code': 'sz','name': '深圳','map': '22.543099, 114.05786799999998'},
'9':
{'id': '9','code': 'sh','name': '上海','map': '31.230393,121.473704'},
'10':
{'id': '10','code': 'gz','name': '广州','map': '23.129163,113.26443500000005'}
}
解析测试类
public class Test {
class City{
int id;
String name;
String code;
String map;
}
public static void main(String[] args) {
String jsonStr="Json字符串";
Map<String, City> citys = new Gson().fromJson(jsonStr, new TypeToken<Map<String, City>>() {}.getType());
System.out.println(citys.size());
}
}
