【FastJson】使用FastJson将Json数组转换成字符串_fastjson解析json文件,输出celldata转字符串

代码实现
可以看出，Json数据像一个数组，里面的每一个元素都是一个对象，所以我们首先要定义出一个对象来存储数据

public class Film {
    private String rating;
    private String rank;
    private String cover_url;
    private String is_playable;
    private String id;
    private String types;
    private String regions;
    private String title;
    private String url;
    private String release_date;
    private String actor_count;
    private String vote_count;
    private String score;
    private String actors;
    private String is_watched;

    @Override
    public String toString() {
        return rating + "\t" +
                rank + "\t" +
                cover_url + "\t" +
                is_playable + "\t" +
                id + "\t" +
                types + "\t" +
                regions + "\t" +
                title + "\t" +
                url + "\t" +
                release_date + "\t" +
                actor_count + "\t" +
                vote_count + "\t" +
                score + "\t" +
                actors + "\t" +
                is_watched;
    }

    public void set(String rating, String rank, String cover_url, String is_playable, String id, String types, String regions, String title, String url, String release_date, String actor_count, String vote_count, String score, String actors, String is_watched) {

然后我们将jJson数据进行转换

import com.alibaba.fastjson.JSONReader;

import java.io.BufferedWriter;
import java.io.FileReader;
import java.io.FileWriter;

public class Json_txt {
    public static void main(String[] args) throws Exception {
        //因为是Json数组，因此使用JsonReader读取
        JSONReader reader = new JSONReader(new FileReader("D:\\MP\\豆瓣\\data.json"));
        BufferedWriter bw = new BufferedWriter(new FileWriter("D:\\MP\\豆瓣\\data.txt"));
        //数组开始读取
        reader.startArray();
        while (reader.hasNext()) {
            //将Json数组的每一个元素转换成对象
            Film film = reader.readObject(Film.class);
            //写出对象
            bw.write(film.toString());
            bw.write("\n");
            //刷新，防止数据残留
            bw.flush();
        }
        //结束数组读取
        reader.endArray();
        bw.close();
    }
}
