用Java读取Properties文件六种方法
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);
