数据连接池的学习

public class DruidDemo {
    public static void main(String[] args) throws Exception {
        //1.导入jar包

        //2.定义配置文件

        //3.加载配置文件
        Properties prop = new Properties();
        prop.load(new FileInputStream("src/druid.propertise"));
        //4.获取连接池对象
        DataSource dataSource = DruidDataSourceFactory.createDataSource(prop);
        //5.获取数据库连接Connection
        Connection connection = dataSource.getConnection();
        System.out.println(connection);
    }
