1.使用java.util.Properties类的load()方法

示例:

Java代码
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:

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

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

示例:

Java代码
InputStream in = new BufferedInputStream(new FileInputStream(name));   
  ResourceBundle rb = new PropertyResourceBundle(in); 

4.使用class变量的getResourceAsStream()方法 

示例:

Java代码
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:

Java代码
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:

Java代码
InputStream in = ClassLoader.getSystemResourceAsStream(name);   
  Properties p = new Properties();   
  p.load(in); 

7.使用apache的PropertiesConfiguration类

示例:
Java代码
Configuration config = new PropertiesConfiguration("test.properties");
config.getProperty(key);
