遇到这个问题之前，我先遇到的问题就是如图所示的bug

![1763f1e49e6b4d2288477c9988231cb7.png][]

简而言之就是说找不到dao层的bean，建议我将dao配置到spring中，但是我已经为dao加了注解，如图

mapper注解理应自动将这个类配置到了spring中，后续帮助我自动注入，但是他没起到作用

只能尝试用@MapperScan，扫描dao层，如图

所以我在主类上加了个MapperScan

结果上面的报错消失了，取而代之的就是今天的主题报错

没有办法，只能继续研究，

截取一段，我们重点研究：

> Error creating bean with name 'tbUserDao' defined in file: Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Property 'sqlSessionFactory' or 'sqlSessionTemplate' are required

他还是说创建bean出错，调用初始化方法失败，不一样的是IllegalArgumentException: Property 'sqlSessionFactory' or 'sqlSessionTemplate' are required

对于这个报错的解决方法就要去检查你自己的依赖了，我创建springboot项目的时候用的默认最新板3.0的，后期我改成了2.3.4，但是mybatis的依赖没有跟着改，我将mybatis的版本降低，清空缓存重启后，问题解决，如图
