J2SE API读取Properties文件的六种方法2011-02-28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);
