使用Java 读取Properties文件的六种方法(转)

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);
