在springboot升级到3.2时，服务启动报错 java.lang.IllegalArgumentException: Invalid value type for attribute ‘factoryBeanObjectType’: java.lang.String：

这主要是因为 mybatis-plus 依赖的 mybatis-spring 版本低导致的问题，只需要将 mybatis-spring 升级到3.0以上就可以了，将原来的依赖排除掉添加高版本的依赖项：

<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-jdbc</artifactId>
</dependency>
<dependency><groupId>com.baomidou</groupId><artifactId>mybatis-plus-boot-starter</artifactId><version>3.5.4.1</version><exclusions><exclusion><groupId>org.mybatis</groupId><artifactId>mybatis-spring</artifactId></exclusion></exclusions>
</dependency>
<dependency><groupId>org.mybatis.spring.boot</groupId><artifactId>mybatis-spring-boot-starter</artifactId><version>3.0.3</version>
</dependency>
<dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>8.0.33</version>
</dependency>

重新加载maven就可以解决问题。
