2、oracle資料庫配置

<dependency>
    <groupId>com.oracle</groupId>
    <artifactId>ojdbc6</artifactId>
    <version>11.2.0</version>
</dependency>

3、更新pom.xml後，記得使用maven更新一下專案

4、我本地裝的是oracle ，在我將MySQL更換成oracle後總是報錯
後來在網上搜到

mvn install:install-file -Dfile=ojdbc.jar -DgroupId=com.oracle -DartifactId=ojdbc6 -Dversion=11.2.0 -Dpackaging=jar

還是不可以，後來更新maven後才可以，估計不用執行這，直接更新maven就可以了
