Json2:使用gson解析为List和Map

import java.lang.reflect.Type;import java.util.List;import com.google.gson.Gson;import com.google.gson.reflect.TypeToken;public class Json解析成List {    public static void main(String[] args) {        StringBuilder sb = new StringBuilder();        sb.append("[");        sb.append(" {‘name‘:‘张辽‘,‘power‘:93},");        sb.append(" {‘name‘:‘徐晃‘,‘power‘:94},");        sb.append(" {‘name‘:‘张郃‘,‘power‘:91},");        sb.append(" {‘name‘:‘于禁‘,‘power‘:90},");        sb.append(" {‘name‘:‘乐进‘,‘power‘:87}");        sb.append("]");        String json = sb.toString();        Gson gson = new Gson();        // 将 json 转化成List泛型        Type t = new TypeToken<List<People>>() {}.getType();        List<People> ps = gson.fromJson(json, t);        System.out.println(ps);        System.out.println(ps.get(1).getName() + "," + ps.get(1).getPower());    }}

运行结果:

[People@4770a4d0, People@34547854, People@15a7eda3, People@43e27370, People@4808e0e1]
徐晃,94

import java.util.Map;import java.lang.reflect.Type;import com.google.gson.Gson;import com.google.gson.reflect.TypeToken;public class Json解析成map {    public static void main(String[] args) {        StringBuilder sb = new StringBuilder();        sb.append("{");        sb.append(" ‘锦马超‘:{‘name‘:‘马超‘,‘Power‘:96},");        sb.append(" ‘猛张飞‘:{‘name‘:‘张飞‘,‘Power‘:96}");        sb.append("}");        String json = sb.toString();        Gson gson = new Gson();        // 将json转化成 Map泛型        Type t = new TypeToken<Map<String, People>>() {        }.getType();        Map<String, People> map = gson.fromJson(json, t);        System.out.println(map);    }}

运行结果:

{锦马超=People@8c3d026, 猛张飞=People@6f967348}

 

辅助类:

public class People {    private String name;    private int power;    public String getName() {        return name;    }    public void setName(String name) {        this.name = name;    }    public int getPower() {        return power;    }    public void setPower(int power) {        this.power = power;    }}
