The UML project's code:

public void cc()
 {
  Properties pro = new Properties();
  try
  {
   File file = new File("./config/cc.properties");
   InputStream in = new BufferedInputStream(new FileInputStream(file)); 
   pro.load(in); 
   System.out.println(pro.getProperty("tu"));
  } catch (IOException e)
  {
   // TODO Auto-generated catch block
   e.printStackTrace();
  }
  
 }


This suitation is used for properties file as same level with this class.
public void cc()
 {
  Properties pro = new Properties();
  try
  {
   pro.load(this.getClass().getResourceAsStream("cc.properties"));
   pro.load(in); 
   System.out.println(pro.getProperty("tu"));
  } catch (IOException e)
  {
   // TODO Auto-generated catch block
   e.printStackTrace();
  }
  
 }


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);
