fastjson list转json

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);
