如何使用java在现有的json文件中添加属性

import com.fasterxml.jackson.databind.JsonNode;
import com.fasterxml.jackson.databind.ObjectMapper;

import java.io.File;
import java.io.FileWriter;
import java.io.IOException;

public class JsonManipulationExample {
    public static void main(String[] args) {
        // 1. 读取JSON文件并解析为Java对象
        ObjectMapper objectMapper = new ObjectMapper();
        File jsonFile = new File("path/to/your/json/file.json");
        try {
            JsonNode rootNode = objectMapper.readTree(jsonFile);

            // 2. 添加属性到Java对象
            ((ObjectNode) rootNode).put("newProperty", "newValue");

            // 3. 将Java对象转换回JSON字符串
            String jsonString = objectMapper.writeValueAsString(rootNode);

            // 4. 将JSON字符串写入原始JSON文件
            FileWriter writer = new FileWriter(jsonFile);
            writer.write(jsonString);
            writer.close();

            System.out.println("属性添加成功！");
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
