通过配置文件注册JDBC驱动

Properties pro = new Properties();
ClassLoader classLoader = JDBCutils.class.getClassLoader();
URL res  = classLoader.getResource("jdbc.properties");
String path = res.getPath();
pro.load(new FileReader(path));
url = pro.getProperty("url");
user = pro.getProperty("user");
password = pro.getProperty("password");
driver = pro.getProperty("driver");
Class.forName(driver);
     

jdbc.properties文件放在src目录下
