Java读取yml配置文件到map中

public class App {
	//存储配置属性的Map集合
    public static Map<String, Object> conf = new HashMap<String, Object>();

    public static void main(String[] args) throws IOException {
        //从classpath下获取配置文件路径
        URL url = App.class.getResource("/conf.yml");
        Yaml yaml = new Yaml();
        //通过yaml对象将配置文件的输入流转换成map原始map对象
        Map map = yaml.loadAs(new FileInputStream(url.getPath()), Map.class);
        //递归map对象将配置加载到conf对象中
        loadRecursion(map, "");

        System.out.println(conf.get("mysql.database1.table1"));
    }
	
	//递归解析map对象
    public static void loadRecursion(Map<String, Object> map, String key){
        map.forEach((k,v) -> {
            if(isParent(v)){
                Map<String, Object> nextValue = (Map<String, Object>) v;
                loadRecursion(nextValue, (("".equals(key) ? "" : key + ".")+ k));
            }else{
                conf.put(key+"."+k,v);
            }
        });
    }
	
	//判断是否还有子节点
    public static boolean isParent(Object o){
