Java解析json报文实例解析

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": [
    {
     "day": "2016-09-01",
     "desc": "建议用露质面霜打底，水质无油粉底霜，透明粉饼，粉质胭脂。",
     "name": "化妆指数",
     "status": "控油"
    },
    {
     "day": "2016-09-01",
     "desc": "感冒容易发生，少去人群密集的场所有利于降低感冒的几率。",
     "name": "感冒指数",
     "status": "易发"
    },
    {
     "day": "2016-09-01",
     "desc": "洗车后，可保持2天车辆清洁，比较适宜洗车。",
     "name": "洗车指数",
     "status": "较适宜"
    },
    {
     "day": "2016-09-01",
     "desc": "易感人群应适当减少室外活动。",
     "name": "空气污染扩散指数",
     "status": "中"
    },
    {
     "day": "2016-09-01",
     "desc": "天气较热，衣物精干简洁，室内酌情添加空调衫。",
     "name": "穿衣指数",
     "status": "热"
    },
    {
     "day": "2016-09-01",
     "desc": "辐射较弱，涂擦SPF12-15、PA+护肤品。",
     "name": "紫外线指数",
     "status": "弱"
    },
    {
     "day": "2016-09-01",
     "desc": "天气较好，且紫外线辐射不强，适宜户外运动。",
     "name": "运动指数",
     "status": "适宜"
    },
    {
     "day": "2016-09-01",
     "desc": "气压小幅波动，可能会影响鱼儿的进食。",
     "name": "钓鱼指数",
     "status": "较适宜"
    }
   ]
  }
 },
 "msg": "success",
 "rc": {
  "c": 0,
  "p": "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;
  }
