如何使用snakeyaml从yaml中获取Map<String，List<Data>>

public class Data {
    private String name;
    private int value;

    // 构造函数、getter 和 setter 方法
    public Data() {}

    public Data(String name, int value) {
        this.name = name;
        this.value = value;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getValue() {
        return value;
    }

    public void setValue(int value) {
        this.value = value;
    }
}

import org.yaml.snakeyaml.Yaml;
import java.util.List;
import java.util.Map;

public class YamlParser {
    public static void main(String[] args) {
        String yamlString = "key1:\n" +
                            "  - name: item1\n" +
                            "    value: 10\n" +
                            "  - name: item2\n" +
                            "    value: 20\n" +
                            "key2:\n" +
                            "  - name: item3\n" +
                            "    value: 30";

        Yaml yaml = new Yaml();
        Map<String, List<Data>> dataMap = yaml.load(yamlString);

        // 打印结果
        for (Map.Entry<String, List<Data>> entry : dataMap.entrySet()) {
            System.out.println("Key: " + entry.getKey());
            for (Data data : entry.getValue()) {
                System.out.println("  Name: " + data.getName() + ", Value: " + data.getValue());
            }
        }
    }
}
