Java读取Properties文件

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

InputStream in = new BufferedInputStream(new FileInputStream(name));

Properties p = new Properties();

p.load(in);

 

2、使用java.util.ResourceBundle类的getBundle()方法

ResourceBundle rb = ResourceBundle.getBundle(name, Locale.getDefault());

 

3、使用java.util.PropertyResourceBundle类的构造函数

InputStream in = new BufferedInputStream(new FileInputStream(name));

ResourceBundle rb = new PropertyResourceBundle(in);

 

4、使用class变量的getResourceAsStream()方法

InputStream in = getClass().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

InputStream in = getClass().getClassLoader().getResourceAsStream(name);

Properties p = new Properties();

p.load(in);

 

6、使用java.lang.ClassLoader类的getSystemResourceAsStream()静态方法

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);
