报错大意：factoryBeanObjectType 属性值类型无效
探索过程
显然这个错误不是我们代码内部出错导致的
应该是jar包版本的问题，但是我MybatisPlus的起步依赖已经是目前最高版本了3.5.4
那有没有可能是Maven依赖传递的问题呢？还真让我发现了
在这个起步依赖的直接依赖中，myBatis-Spring的版本竟然是2.1.1
而我的SpringBoot版本是3.2.0，试试换一个myBatis-Spring的版本
成了！
总结
问题原因：这个问题是由于依赖传递导致，在MyBatis起步依赖中的myBatis-spring版本过低，导致程序无法运行
解决方法：在pom.xml文件中配置一个更高版本的myBatis-spring依赖即可，别忘了刷新maven配置哦~
