我的pom文件里使用

mybatis-plus

<dependency>
                <groupId>com.baomidou</groupId>
                <artifactId>mybatis-plus-boot-starter</artifactId>
                <version>3.3.2</version>
            </dependency>

但是我的Spring Boot版本比较低，而mybatis-plus使用的mybatis版本比较高导致

所以我们要自己控制mybatis版本

解决方法是自己引入mybatis：

        <dependency>
            <groupId>org.mybatis.spring.boot</groupId>
            <artifactId>mybatis-spring-boot-starter</artifactId>
            <version>2.1.3</version>
        </dependency>
