Java 加载Properties文件的六种方式


 

 
1。使用java.util.Properties类的load()方法 
示例: I
 
nputStream 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);
