文件流未关闭会不会有问题

[ls9527]

在代码 com.baidu.disconf.client.support.utils.ConfigLoaderUtils#loadWithTomcatMode
没有关闭文件流, 虽然只打开一次. 但是这样写会不会还是不妥

 private static Properties loadWithTomcatMode(final String propertyFilePath)
            throws Exception {

        Properties props = new Properties();

        try {

            // 先用TOMCAT模式进行导入

            URL url = ClassLoaderUtil.getLoader().getResource(propertyFilePath);
            URI uri = new URI(url.toString());
            props.load(new InputStreamReader(new FileInputStream(uri.getPath()), "utf-8"));

        } catch (Exception e) {

            // http://stackoverflow.com/questions/574809/load-a-resource-contained-in-a-jar
            props.load(new InputStreamReader(ClassLoaderUtil.getLoader().getResourceAsStream(propertyFilePath),
                    "utf-8"));
        }
        return props;
    }
