1。使用java.util.Properties類的load()方法
    示例： InputStream in = lnew BufferedInputStream(new FileInputStream(name));
    Properties p = new Properties();
    p.load(in);
    2。使用java.util.ResourceBundle類的getBundle()方法
    示例： ResourceBundle rb = ResourceBundle.getBundle(name, Locale.getDefault());
    3。使用java.util.PropertyResourceBundle類的構(gòu)造函數(shù)
    示例： InputStream in = new BufferedInputStream(new FileInputStream(name));
    ResourceBundle rb = new PropertyResourceBundle(in);
    4。使用class變量的getResourceAsStream()方法
    示例： InputStream in = JProperties.class.getResourceAsStream(name);
    Properties p = new Properties();
    p.load(in);
    5。使用class.getClassLoader()所得到的java.lang.ClassLoader的getResourceAsStream()方法
    示例： InputStream in = JProperties.class.getClassLoader().getResourceAsStream(name);
    Properties p = new Properties();
    p.load(in);
    6。使用java.lang.ClassLoader類的getSystemResourceAsStream()靜態(tài)方法
    示例： InputStream in = ClassLoader.getSystemResourceAsStream(name);
    Properties p = new Properties();
    p.load(in);
    補充
    Servlet中可以使用javax.servlet.ServletContext的getResourceAsStream()方法
    示例：InputStream in = context.getResourceAsStream(path);
    Properties p = new Properties();
    p.load(in);
