这篇文章主要介绍了Java解析json报文实例解析,文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价值,需要的朋友可以参考下
json报文如下：
{
"code": 0,
"data": {
"city": {
"cityId": 284609,
"counname": "中国",
"name": "东城区",
"pname": "北京市"
},
"liveIndex": {
"2016-09-01": [
{

]
}
},
"msg": "success",

}
}
java解析json代码：
public static City getCity(String json){
JSONObject jsonObject = (JSONObject) JSONObject.parseObject(json)
.getJSONObject("data")
.getJSONObject("city");
City city = new City();
city.setCityId(Integer.parseInt(String.valueOf(jsonObject.get("cityId"))));
city.setCityName((String) jsonObject.get("pname"));
city.setCunName((String)jsonObject.get("counname"));
city.setDistrictName((String)jsonObject.get("name"));
return city;
}
public static List<Life> getLife(String lifeJson){
List list = new ArrayList();
JSONObject jsonObject = (JSONObject) JSONObject.parseObject(lifeJson)
.getJSONObject("data")
.getJSONObject("liveIndex");
JSONArray jsonArray = jsonObject.getJSONArray(getFormatDate());
for(int i = 0; i < 8; i++){
Life life = new Life();
life.setDay(new Date());
life.setDesc(jsonArray.getJSONObject(i).getString("desc"));
life.setName(jsonArray.getJSONObject(i).getString("name"));
life.setStatus(jsonArray.getJSONObject(i).getString("status"));
life.setCity(getCity(lifeJson));
list.add(life);
}
return list;
}
