To connect, you need to get aConnectioninstance from JDBC. To do this, you use theDriverManager.getConnection()method: Connection db = DriverManager.getConnection(url, username, password); Connection Parameters In addition to the standard connection parameters the driver supports a number of additional...

加载JDBC驱动 在应用中执行以下命令加载JDBC驱动: Class.forName("com.aliyun.polardb2.Driver"); 说明 如果是通过项目导入的方式导入JDBC,以上驱动都会自动注册完成,不需要额外注册。 连接数据库 在JDBC中,一个数据库通常用一个URL来表示,示例如下: jdbc:polardb://pc-***.o.polardb.rds.aliyuncs.com:1521/pol...
