你这oracle驱动没加载啊,

http://mvnrepository.com/artifact/oracle

要对应你的oracle版本,上面是maven仓库的信息(ojdbc)

下面是pom配置文件:<?xml version="1.0" encoding="UTF-8"?>

下面是application.properties:

Cannot load driver class: oracle.jdbc.driver.OracleDriver
不能加载驱动 !!!

看着像 oracle ojdbc的版本不对,ojdbc6 配的是jdk6,换个版本试试,中央仓库应该没有资源,你要重新下载个,然后打到本地的maven仓库

 Cannot load driver class: oracle.jdbc.driver.OracleDriver

报错信息确实说的是不能加载驱动,,题主检查下配置依赖了没,,

是不是没有引入mybatis包,


org.mybatis
mybatis
3.4.5

我也碰到过,这个是因为你的配置文件中配置jpa的那几个属性后面有空格,在springboot的jpa配置中,jpa的那几个属性=后面是不能有空格的。。。
