SpringBoot错误:未找到driverClassName = oracle.jdbc.driver.OracleDriver的已注册驱动程序,尝试直接实例化

Question

我正在学习SpringBoot,我只是尝试运行我曾经成功运行的项目,但现在弹出这个错误

 enter cod2018-08-25 11:30:21 WARN  c.z.hikari.util.DriverDataSource - Registered driver with driverClassName=oracle.jdbc.driver.OracleDriver was not found, trying direct instantiation.

在这几个异常被抛出之后......

我尝试了一些调试,比如1.手动检查oracle.jdbc.driver.OracleDriver是否存在.2.使用其他ojdbc之类的6. 3. maven更新.

但似乎没有任何效果.任何帮助表示赞赏.

UPDATE

我不知道为什么,但我重新启动了我的系统,现在它工作正常.

Answer 1

关于问题标题的警告信息:

未找到driverClassName = oracle.jdbc.driver.OracleDriver的已注册驱动程序,尝试直接实例化

那是因为您使用了错误的值: spring.datasource.driver-class-name

用oracle.jdbc.OracleDriver而不是oracle.jdbc.driver.OracleDriver

请参阅此处的详细答案:https://stackoverflow.com/a/6202721/3581539

Answer 2

您必须使用oracle.jdbc.OracleDriver而不是oracle.jdbc.driver.OracleDriver在POM文件中

Answer 3

明显提示驱动缺失，请检查maven本地仓库，在XX:\user\XXX\m2\XX中查找jdbc驱动jar文件

从 oracle网站使用 JDK 8 连接 Oracle 12 您可以按照此操作。

<groupid>com.oracle.jdbc</groupid>
<artifactid>ojdbc8</artifactid>
<version>12.2.0.1</version>
