ClassNotFoundException：oracle.jdbc.OracleDriver

时间：2017-06-14 07:39:07

标签： java xml oracle hibernate maven

我想在我的maven项目中使用hibernate。我将hibernate.cfg.xml和hibernate.reveng.xml添加到资源中，还将hibernate和oracle驱动程序添加到pom.xml中，但问题是它无法识别oracle驱动程序类。

这是输出

确保将ojdbc7.jar添加到类路径中。

1.Add ojdbc7.jar to TOMCAT_HOME/lib
2.Add ojdbc7.jar to JAVA_HOME/jre/lib
3.Trying with ojdbc6.jar if it still not works

在maven中心没有OJDBC驱动程序，这就是为什么maven找不到它。 您需要从oracle主页手动下载它。

然后，您可以将其部署到自托管的maven存储库，并将该存储库添加到您的pom，或者直接将jar文件添加到您的类路径中。
