@Test
public void getConnection() throws Exception {
    //1 读取配置文件中的4个基本信息
    InputStream is = JDBC_Utils.class.getClassLoader().getResourceAsStream("../../jdbc.properties");

    Properties pros = new Properties();
    pros.load(is);

    String user = pros.getProperty("user");
    String password = pros.getProperty("password");
    String url = pros.getProperty("url");
    String driverClass = pros.getProperty("driverClass");

    System.out.println("----");
    System.out.println("driverClass = " + driverClass);
    System.out.println("url = " + url);

    //2 加载驱动
    Class.forName(driverClass);

    //3 获取连接
    Connection connection = DriverManager.getConnection(url, user, password);
    System.out.println(connection);
}
