我使用的IDE是IDEA,springBoot的版本是2.0以下的,所有配置信息也是完全跟老师视频的配置信息相同的
这是我的项目目录结构
我已经把mybatis-config.xml所在的目录设置资源目录了
下面是输出的target文件夹,里面也有mybatis-config.xml文件,但是报错信息就是找不到
之前在问答里面看到也有其他同学遇到了相同的问题,但好像都没有解决,麻烦老师再帮我看一下这个问题
这是我的代码(我这个去掉了加密功能)

#数据库驱动

#数据库用户名(已加密)
jdbc.username=root
#数据库密码(已加密)
jdbc.password=12345ysp
#MyBatis
#mybatis-config.xml配置文件的路径
