fastjson List<> 转Json , Json 转List<>

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{
