Java項目啓動時，oracle 驅動異常

報錯信息：項目啓動的時候，一直會報“registered driver with driverclassname=oracle.jdbc.driver.oracledriver was not found, trying direct instantiation.”。

原因： Oracle 9i 之後，建議使用 oracle.jdbc.OracleDriver ，而不是 oracle.jdbc.driver.OracleDriver。

官方建議原文：For Oracle 9i onwards you should use oracle.jdbc.OracleDriver rather than oracle.jdbc.driver.OracleDriver as Oracle have stated that oracle.jdbc.driver.OracleDriver is deprecated and support for this driver class will be discontinued in the next major release.
