【java编程】加载Resources配置文件的方法

一、加载配置实现k-v

//FILTER_PROPERTY_NAME=META-INF/abc.properties
private void loadFilterConfig(Properties filterProperties, ClassLoader classLoader) throws IOException {
        if (classLoader == null) {
            return;
        }

        for (Enumeration<URL> e = classLoader.getResources(FILTER_PROPERTY_NAME); e.hasMoreElements();) {
            URL url = e.nextElement();

            Properties property = new Properties();

            InputStream is = null;
            try {
                is = url.openStream();
                property.load(is);
            } finally {
                if (is != null) {
                    is.close();
                }
            }

            filterProperties.putAll(property);
        }
    }
