JDK17 + springboot-3.1.2 + mybatis-2.0.0

写完简单的登录接口启动之后，抛出错误如下：

解决方案

删除mybatis3.5.2依赖

   <dependency>  
        <groupId>org.mybatis</groupId>  
        <artifactId>mybatis</artifactId>  
        <version>3.5.2</version>  
    </dependency> 

升级mybatis-spring-boot-starter依赖，由2.0.0升级到3.0.0

 <dependency>  
        <groupId>org.mybatis.spring.boot</groupId>  
        <artifactId>mybatis-spring-boot-starter</artifactId>  
        <version>3.0.0</version>  
 </dependency>
