MyBatis-Plus 调用service.save()方法正常的，为啥在调用saveBatch()方法时会出现映射不到的问题

当前使用版本(必填,否则不予处理)

    <dependency>
        <groupId>com.baomidou</groupId>
        <artifactId>mybatis-plus-boot-starter</artifactId>
        <version>3.5.1</version>
    </dependency>

该问题是如何引起的？(确定最新版也有问题再提!!!)

重现步骤(如果有就写完整)

提供了demo，可调用接口重现报错 demo.zip

serviceImpl 的泛型传递错误，没有传递业务 Mapper 的类型，而是传递了 BaseMapper
