在将java对象转换为yaml文件的同时，还添加了对象名称

import org.yaml.snakeyaml.Yaml;
import java.io.FileWriter;
import java.io.IOException;

public class JavaObjectToYaml {
    public static void main(String[] args) {
        // 创建一个Java对象
        Person person = new Person("John Doe", 30);

        // 将Java对象转换为YAML格式
        Yaml yaml = new Yaml();
        String yamlString = yaml.dump(person);

        // 添加对象名称到YAML字符串中
        String yamlWithObjectName = "person:\n" + yamlString;

        // 将YAML字符串写入文件
        try (FileWriter writer = new FileWriter("person.yaml")) {
            writer.write(yamlWithObjectName);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

class Person {
    private String name;
    private int age;

    public Person(String name, int age) {
        this.name = name;
        this.age = age;
    }

    // 省略getter和setter方法
}
