java 读取配置文件(1)(.properties后缀)

方法一:

Properties prop = new Properties();//属性集合对象    
           FileInputStream fis = new FileInputStream("D:\\db.properties");//属性文件流    
           prop.load(fis);//将属性文件流装载到Properties对象中    
           String DB_URL= prop.getProperty("oracleurl");
           String DB_DRIVER=prop.getProperty("oracledriver");
           String DB_USERNAME=prop.getProperty("oracleuser");
           String DB_PASSWORD=prop.getProperty("oraclepassword");

方法二:

            ResourceBundle bundle = ResourceBundle.getBundle("payment");//读取payment.properties
            String  securityUtilPrivateKey = bundle.getString("securityUtilPrivateKey")
