SpringBoot整合oracle遇到的问题，由于SpringBoot是jdk1.8以上的就会导致ojdbc6和ojdbc14连接不行需要ojdbc8,由于oracle的jdbc连接是不支持maven直接下载的 所以需要下载jar包之后安装到maven本地仓库或者远程仓库:
jdbc8-12.2.0.1.jar包下载链接：官方下载链接：/maven2/com/oracle/database/jdbc/
或者本人CSDN资源下载地址：/download/nan1996jiang/13713299
解决方式：
使用WIN+R打开命令提示符输入cmd；输入该命令：mvn install:install-file -Dfile=F:\ojdbc8-12.2.0.1.jar -DgroupId=com.oracle -DartifactId=ojdbc8 -Dversion=12.2.0.1 -Dpackaging=jar -DgeneratePom=true
指令参数
install:可以将项目本身编译并打包到本地仓库 install-file:安装文件 -Dfile=F:\ojdbc8-12.2.0.1.jar : 指定要打的包的文件位置 -DgroupId=com.oracle : 指定当前包的groupId为com.oracle -DartifactId=ojdbc8 : 指定当前的artifactfactId为ojdbc8 -Dversion=12.2.0.1 : 指定当前包的版本为12.2.0.1-DgeneratePom=true:是否生成pom文件-DgroupId=包名-DartifactId=项目名-Dversion=版本号-Dpackaging=jar-Dfile=jar文件所在路径
看到提示BUILD SUCCESS就表示成功了，然后再在SpringBoot项目当中引入pom坐标
<!--oracle连接驱动--><dependency><groupId>com.oracle</groupId><artifactId>ojdbc8</artifactId><version>12.2.0.1</version></dependency>
