user=rootpassword=rootjdbcUrl=jdbc:mysql://127.0.0.1:3306/test?useUnicode=true&characterEncoding=UTF-8;driverClass=com.mysql.jdbc.Driver

调用方法：

public void getProperties(){		Properties prop = new Properties();		try {			prop.load(new BufferedInputStream(new FileInputStream(this.getClass().getResource("/").getPath().substring(1)+"system.properties")));			System.out.println(prop.getProperty("user"));			System.out.println(prop.getProperty("password"));			System.out.println(prop.getProperty("jdbcUrl"));			System.out.println(prop.getProperty("driverClass"));		} catch (FileNotFoundException e) {			// TODO Auto-generated catch block			e.printStackTrace();		} catch (IOException e) {			// TODO Auto-generated catch block			e.printStackTrace();		}	}
