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;
}
}
