问题描述

出现该错误的原因是Pom.xml中的mybatis-plus引用版本错误。我使用的spring-boot3版本，但mybatis-plus却引用的是spring-boot2对应的start。

原mybatis-plus版本:

        <dependency>
           <groupId>com.baomidou</groupId>
           <artifactId>mybatis-plus-boot-starter</artifactId>
           <version>3.5.1</version>
       </dependency>

修改后的mybatis-plus版本

<dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-spring-boot3-starter</artifactId>
            <version>3.5.5</version>
        </dependency>
