抽象父类中调用mapper时如何mock

增删改查太多，把常用的处理逻辑写在了抽象父类。
场景是这样，AServiceImpl实现了AService接口，继承了AbstractService抽象类，AServiceImpl部分方法直接super调用。
AbstractService通过AServiceImpl重写的getMapper方法获得相应mapper的引用，然后调用mapper的相关方法。
我在测试AServiceImpl相关方法的时候，尝试mock mapper的相关方法，但是不起作用，而且日志里也没有打印抽象类内部的调用链路。请问是我的操作有问题吗？

Start with the AServiceImpl test scenario described in the issue, then trace AbstractService#getMapper and the mapper calls reached through super. Reproduce the mock setup and inspect whether the abstract-class call path is exercised; done means the cause of the ineffective mock and missing logs is demonstrated by a focused test.
