 After analyzing the problem, it was found that the select package under mybatis was referenced.

 This package was not found in my maven pom.xml

Use your special move and execute it in the idea terminal window

mvn dependency:tree > a.txt

All maven dependency packages of the project will be generated in the project directory.

 The mybatis jar package was introduced in the pagehelper paging plug-in.

Next, the problem is easily solved. Find the pagehelper dependency in the project and exclude the package mybatis dependency.

        <!--pagehelper-->
        <dependency>
            <groupId>com.github.pagehelper</groupId>
            <artifactId>pagehelper-spring-boot-starter</artifactId>
            <version>1.2.13</version>
            <exclusions>
                <exclusion>
                    <artifactId>mybatis</artifactId>
                    <groupId>org.mybatis</groupId>
                </exclusion>
            </exclusions>
        </dependency>

 After completing the above operations, restart the project and the startup is successful.
