java操作properties文件

properties文件放在src根目录下

public static void main(String args[]) {
		Properties props = new Properties();
		try {
			InputStream is = ClassLoader.getSystemResourceAsStream("prop.properties");
			props.load(is);
			String address = props.getProperty("address");
			System.out.println(address);
		} catch (Exception e) {
			e.printStackTrace();
		}  
	}
