【SpringBoot】SpringBoot3.X 兼容 mybatis-plus 解决全过程

1、事件起因

最近闲来无事，将springboot 2.X 升级到 springboot 3.X，整个3.X的项目

springboot 采用3.X后，结果出现各种问题，网上也是一堆的解决方案，可惜很多方案并不适合自己

2、网络上的解决方案

首先罗列下网络上的解决方案，此处先声明一下：不是说网络上的各种方案是有问题的，只是说明网络上有着各种方案，由于我们所处的环境不一样，出现的问题也不尽相同

2.1springboot由3.1.5升级到3.2.0 报Invalid value type for attribute ‘factoryBeanObjectType‘: java.lang.String

2.1.1 表现形式
