maven项目怎么读取properties文件

[tjzero_sapce]

小弟有个练手的maven项目，文件结构如图，DBPoolConnection需要读取properties，路径总写不对，

static {
        Properties properties = loadPropertiesFile(path);
        try {
            druidDataSource = (DruidDataSource) DruidDataSourceFactory.createDataSource(properties); //DruidDataSrouce工厂模式
        } catch (Exception e) {
            log.error("获取配置失败");
        }
    }

private static Properties loadPropertiesFile(String fullFile) {
        String webRootPath = null;
        if (null == fullFile || fullFile.equals("")){
            throw new IllegalArgumentException("Properties file path can not be null" + fullFile);
        }
        webRootPath = DBPoolConnection.class.getClassLoader().getResource("").getPath();
        webRootPath = new File(webRootPath).getParent();
        InputStream inputStream = null;
        Properties p =null;
        try {
            inputStream = new FileInputStream(new File(webRootPath + File.separator + fullFile));
            p = new Properties();
            p.load(inputStream);
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            try {
                if (null != inputStream){
                    inputStream.close();
                }
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
        return p;
    }

DBPoolConnection.class.getClassLoader().getResource("/"+fullFile)

那我第二行的 path 应该怎么写呢？

我想改成相对路径读取properties，这样打成jar之后运行也方便
