J2SE API讀取Properties文件的六種方法（1）

使用J2SE API讀取PropertIEs文件的六種方法：

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類的構造函數

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);
