解析嵌套json字符串，一个json字符串中嵌套另一个json字符串

我现在有一个字符串是这样：

{
     "msg": {
     "resCode": "",
     "attrName": "sensorData",

　　 "result": {
     　　"food1": ,
     　　"water": ,
     　　"food2": ,
     　　"humidity": "152.42",
     　　"temprature": "103.65"
     }
     }
 }

我要获取的是嵌套在msg里的result中的所有数据。

先用msg和result分别创建bean类，把Result作为msg的其中一个变量

 public class SensorBean implements Serializable {

    private Result result;

     private int resCode;

     private String attrName;
     public Result getResult() {
         return result;
     }

     public void setResult(Result result) {
         this.result = result;
     }

     public int getResCode() {
         return resCode;
     }

     public void setResCode(int resCode) {
         this.resCode = resCode;
     }

     public String getAttrName() {
         return attrName;
     }

     public void setAttrName(String attrName) {
         this.attrName = attrName;
     }
     @Override
     public String toString() {
         return "Msg{" +
                 "result=" + result.toString() +
                 ", resCode=" + resCode +
                 ", attrName='" + attrName + '\'' +
                 '}';
     }

 }

两个类都继承序列化

 public class Result implements Serializable{

     /**
      * food1 : 0
      * water : 0
      * food2 : 106
      * humidity : 152.42
      * temprature : 103.65
      */

     private int food1;
     private int water;
     private int food2;
     private String humidity;
     private String temprature;

     public int getFood1() {
         return food1;
     }

     public void setFood1(int food1) {
         this.food1 = food1;
     }

     public int getWater() {
         return water;
     }

     public void setWater(int water) {
         this.water = water;
     }

     public String getTemprature() {
         return temprature;
     }

     public void setTemprature(String temprature) {
         this.temprature = temprature;
     }

     @Override
     public String toString() {
         return "Result{" +
                 "food1=" + food1 +
                 ", water='" + water +
                 ", temprature=" + temprature+ '\''+
                 '}';
     }
 }

然后在获取到数据的地方进行Gson解析

Gson gson = new Gson();
SensorBean sensorBean = gson.fromJson(data.getString("msg"), SensorBean.class);
Result result = sensorBean.getResult();
L.d(TAG, "result.bean = " + result.toString());

这种方法应该是比较费事儿的，不过，没毛病
