找了好久原因，发现是在pom文件里plugin下面多引入了

mybatis-generator-core的 依赖导致；

只需要保留

mysql-connector-java 依赖即可；

注释后修改为如下：

            <!--mybatis-generator插件-->
            <plugin>

<!--                    </dependency>-->
                </dependencies>
            </plugin>

maybe，是因为mybatis-generator-core.jar这个包里有的类没找到
