当前使用版本(必填,否则不予处理)

3.4.2（之前用的3.1是正常的，更新后就不正常了） 配置文件：

/**
 * @description: ㅤ
 * @author: Zek @Date: 2020/4/29 on 1:04 下午
 */
@Slf4j
@MapperScan(basePackages = {"cn.nocov.hospital.*.mapper"})
@Configuration
@EnableTransactionManagement
public class MybatisPlusConfig {

  @Bean
  public MybatisPlusInterceptor mybatisPlusInterceptor() {
    MybatisPlusInterceptor interceptor = new MybatisPlusInterceptor();
    PaginationInnerInterceptor innerInterceptor = new PaginationInnerInterceptor();
    innerInterceptor.setDbType(DbType.MYSQL);
    interceptor.addInnerInterceptor(innerInterceptor);
    return interceptor;
  }
}

该问题是如何引起的？(确定最新版也有问题再提!!!)

打包运行时

重现步骤(如果有就写完整)

ClassNotFoundException发生的原因与mybatisPlus无关，请自行检查依赖冲突等原因
