问题相关代码，请勿粘贴截图

    System.out.println();
    System.out.println(YamlUtil.class.getResource("").getPath());
    System.out.println(YamlUtil.class.getResource("/").getPath());
    System.out.println(Thread.currentThread().getContextClassLoader().getResource("").getPath());
    System.out.println(YamlUtil.class.getClassLoader().getResource("").getPath());

我想要达到的结果

这个好像是因为Java的这些方法默认输出时会带这个斜杠，折中在每个方法后加个.substring(1)去除开头的那个斜杠你看可以不。

public class YamlUtil {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
    
        System.out.println();
        System.out.println(YamlUtil.class.getResource("").getPath().substring(1));
        System.out.println(YamlUtil.class.getResource("/").getPath().substring(1));
        System.out.println(Thread.currentThread().getContextClassLoader().getResource("").getPath().substring(1));
        System.out.println(YamlUtil.class.getClassLoader().getResource("").getPath().substring(1));
    }

}
