使用GSON从Json文件恢复数据

import com.google.gson.Gson;
import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;

public class JsonFileReader {
    public static void main(String[] args) {
        // 读取Json文件内容到字符串
        String json = readFile("data.json");

        // 创建GSON对象
        Gson gson = new Gson();

        // 将Json字符串转换为Java对象
        DataObject dataObject = gson.fromJson(json, DataObject.class);

        // 打印Java对象的属性值
        System.out.println("Name: " + dataObject.getName());
        System.out.println("Age: " + dataObject.getAge());
        System.out.println("Email: " + dataObject.getEmail());
    }

    private static String readFile(String filePath) {
        StringBuilder content = new StringBuilder();
        try (BufferedReader reader = new BufferedReader(new FileReader(filePath))) {
            String line;
            while ((line = reader.readLine()) != null) {
                content.append(line);
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
        return content.toString();
    }
}

class DataObject {
    private String name;
    private int age;
    private String email;

    // 省略构造方法和getter/setter方法
}
