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：

xml 复制代码

    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-jdbc</artifactId>

<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。
