一开始看控制台报错以为是service、mapper没有更新或者扫描到依赖
Error creating bean with name 'xxxController': Unsatisfied dependency expressed through field 'xxxService'
尝试maven各种clean、install；加@Service、@Mapper、@component、@ComponentScan各种注解还是无解
留意到最后两项报错

查阅资料后发现是mybatis-plus版本冲突
打开依赖树一看。。。果然爆红了
解决办法也很简单，双击爆红的那线段，找到对应的依赖再把版本改成需要的即可
我这里需要3.4.3的苞米豆，改完ok
