使用J2SE API读取Properties文件的六种方法：
  1.使用Java.util.Properties类的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类的getBundle()方法

示例： ResourceBundle rb = Bundle(name, Default());
　　3.使用java.util.PropertyResourceBundle类的构造函数

　示例： InputStream in = new BufferedInputStream(new FileInputStream(name));
  ResourceBundle rb = new PropertyResourceBundle(in);
  4.使用class变量的getResourceAsStream()方法

示例： InputStream in = ResourceAsStream(name);
  Properties p = new Properties();
  p.load(in);
  5.使用ClassLoader()所得到的java.lang.ClassLoader的getResourceAsStream()方法

　示例： InputStream in = ClassLoader().getResourceAsStream(name);
  Properties p = new Properties();
  p.load(in);
  6.使用java.lang.ClassLoader类的getSystemResourceAsStream()静态方法

示例： InputStream in = SystemResourceAsStream(name);
  Properties p = new Properties();
  p.load(in);
  补充
  Servlet中可以使用javax.servlet.ServletContext的getResourceAsStream()方法

示例：InputStream in = ResourceAsStream(path);
  Properties p = new Properties();
  p.load(in);
