JAVA 小练习-11 fastjson 处理json字符串

下载fastjson
在pom文件中配置：

import com.alibaba.fastjson.JSON;
import com.alibaba.fastjson.JSONArray;
import com.alibaba.fastjson.JSONObject;
import com.alibaba.fastjson.TypeReference;

import java.util.ArrayList;
import java.util.Arrays;
import java.util.Date;
import java.util.List;


public class ParseJson {
    public static void main(String[] args){

//        parseObject方法将对象形式的json字符串转换为对象
        String jsonStr = "{"AGE":15,"DATE OF BIRTH":1635735500370,"FULL NAME":"John Doe"}";
        JSONObject jObj = JSON.parseObject(jsonStr);
        Date dBirth = jObj.getDate("DATE OF BIRTH");
        System.out.println("--------------------------------------");
        System.out.println("jObj"+jObj);
        System.out.println(dBirth);
        System.out.println("00000000000000000000000000000000000000:");

//        parseObject方法将数组形式的json字符串转换为对象数组
        String jsonObjList = "[{"AGE":15,"DATE OF BIRTH":1635738540186,"FULL NAME":"John Doe"},{"AGE":20,"DATE OF BIRTH":1635738540186,"FULL NAME":"Janette Doe"}]";
        Person[] personList = JSON.parseObject(jsonObjList, new TypeReference(){});
        List list = Arrays.asList(personList);
        System.out.println(list);

//        parseArray方法将数组形式的json字符串转换为对象数组
        JSONArray personArray = JSON.parseArray(jsonObjList);
        System.out.println(personArray);
        for(int i=0; i 
输出结果：
