jar讀取外部的配置文件如perperties

private static ResourceBundle rb;
	private static BufferedInputStream inputStream;
	static {
//		rb = ResourceBundle.getBundle("xcc.resourceBundle");
		String proFilePath = System.getProperty("user.dir") + "\\config\\resourceBundle.properties";
		try {
			inputStream = new BufferedInputStream(new FileInputStream(proFilePath));
			rb = new PropertyResourceBundle(inputStream);
			
		} catch (FileNotFoundException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}
