聊聊ResourceBundle和properties读取配置文件的区别

ResourceBundle conf= ResourceBundle.getBundle("config/fnconfig/fnlogin");
String value= conf.getString("key");

Properties prop = new Properties();
try { InputStream is = getClass().getResourceAsStream("xmlPath.properties");
prop.load(is);
//或者直接prop.load(new FileInputStream("c:/xmlPath.properties"));
if (is != null) { is.close();
} } catch (Exception e) { System.out.println( "file " + "catalogPath.properties" + " not found!\n" + e); } String value= prop.getProperty("key").toString();
