如何获取jar包resources文件路径

//相对路径
 private final String xmlPath= "/jenkinspipeline/PipelineConfig.xml";
    public StringBuilder propertyResolverXml(String xmlPath) {
        InputStream resourceAsStream = XmlLocalUtils.class.getResourceAsStream(xmlPath);//读取内容
        StringBuilder xmlStr = new StringBuilder();
        BufferedReader read = null;
        try {
            read = new BufferedReader(new InputStreamReader(resourceAsStream));//转成bufferreader按行读取
            String tempStr;
            while ((tempStr = read.readLine()) != null) {
                xmlStr.append(tempStr);
            }
            read.close();
        } catch (Exception ex) {
            log.error("解析文件异常:", ex);
            throw new NativeSphereCicdException(NativeSphereCicdEnum.PROPERTYRESOLVERXML_EXCEPTION);
        }
        return xmlStr;
    }
