Question

怎么把json数据转化为数组,详细看图片.

Answer 1

用eval函数，将Json数据解析之后添加到数组即可

Answer 2

package com;

import java.util.Arrays;
import java.util.List;

import com.Kensou.Person;
import com.alibaba.fastjson.JSON;

public class Yuma
{

public static void main(String[] args)
{
String str =
"{\"data1\":[{\"name\":\"aa\",\"age\":\"12\"},{\"name\":\"bb\",\"age\":\"13\"}],\"data2\":{\"nowpage\":1,\"pagesize\":2}}";
Kensou p = JSON.parseObject(str, Kensou.class);
Person[] ps = new Person[p.data1.length + p.data2.length];
System.arraycopy(p.data1, 0, ps, 0, p.data1.length);
System.arraycopy(p.data2, 0, ps, ps.length - 1, p.data2.length);
List<Person> pList = Arrays.asList(ps);
System.out.println(pList);
}
}

class Kensou
{
Person[] data1 = { new Person(), new Person() };

Person[] data2 = { new Person() };

class Person
{

String name;

int age;
}

}
