JavaJDBC-使用数据库连接池技术(Druid)获取Connection对象
一、导入对应的jar包
二、创建对应的配置文件(如下只是部分参数)
url=jdbc:mysql://localhost:3306/test username=root password=orz***** driverClassName=com.mysql.cj.jdbc.Driver initialSize=10 maxActive=20
三、获取Connection对象
private static DataSource source;
//静态代码块 static { try { Properties pros=new Properties(); InputStream is = ClassLoader.getSystemClassLoader().getResourceAsStream("druid.properties"); pros.load(is); source=DruidDataSourceFactory.createDataSource(pros); } catch (Exception e) { e.printStackTrace(); } }
//getConnection public static Connection getConnectionByDruid()throws Exception { Connection conn=source.getConnection(); return conn; }
