以下代码在线上失败:

Class.forName("oracle.jdbc.driver.OracleDriver");

有错误:

java.lang.ClassNotFoundException:oracle.jdbc.driver.OracleDriver

两个println印刷品:

这让我觉得这个类存在并且可以找到.此完全相同的类也适用于非servlet应用程序.

    //load the driver
    Class.forName("oracle.jdbc.driver.OracleDriver");

    return DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:orcl", "SYSTEM", "pass");
}
