• Java读取Properties文件的六种方法


    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 = ResourceBundle.getBundle(name, Locale.getDefault());

    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 = 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类的getSystemResourceAsStream()静态方法
    示例: InputStream in = ClassLoader.getSystemResourceAsStream(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 = context.getResourceAsStream(path);
    Properties p = new Properties();
    p.load(in);
