使用Spring读取package里面的Proerites文件

Properties detailProps = loadProperties("com/test.properties");

protected Properties loadProperties(String resource) throws IOException {Properties props = new Properties();InputStream is = null;try {is = ResourceHelper.getClassPathResourceAsInputStream(resource);if (is != null) {propertiesPersister.load(props, new InputStreamReader(is, "UTF-8"));}} finally {IOUtils.closeQuietly(is);}return props;}
