SerializeWriter:相当于StringBuffer
JSONArray:相当于List<Object>
JSONObject:相当于Map<String, Object>
JSON反序列化没有真正数组,本质类型都是List<Object>
比如说List<Strudent>
List转Json
List<Student> students = new ArrayList();
String str = JSON.toJSONString(students); // List转json
Json 转List 方法一
String json = ""; //获取的Json数据
List<Student> students = JSON.parseObject(json,new TypeReference<List<Student>>(){}); // Json 转List
Json 转List方法二
List<Student> students = JSON.parseArray(json,Student.class);
Student 对象要实现Serializable接口
import java.io.Serializable;
public class Student implements Serializable{
