MyBatis-Plus封装抽取多个xxxMapper类作为方法参数

抽取出来的方法：

public void testBaseMapper(String fix, Object reachGoalMapper) {
        int count = ((BaseMapper<Object>)reachGoalMapper).selectCount(new QueryWrapper<Object>().eq("reach_id", 1));
        ReachGoalTemp reachGoalTemp = new ReachGoalTemp;
        if (count < 1) {
            Object rg = null;
            switch (fix) {
                case "2":
                    reachGoalTemp.setDm("2222222");
                    rg = new ReachGoal2();
                    break;
                case "3":
                    reachGoalTemp.setDm("33333");
                    rg = new ReachGoal3();
                    break;
                case "4":
                    reachGoalTemp.setDm("444444");
                    rg = new ReachGoal4();
                    break;
            }
            BeanUtils.copyProperties(reachGoalTemp, rg);
            ((BaseMapper<Object>)reachGoalMapper).insert(rg);
        }
    }

BeanUtils是：org.springframework.beans.BeanUtils，用来复制属性值

Controller层调用：

@Resource
ReachGoalService reachGoalService;
@Resource
ReachGoal2Mapper reachGoal2Mapper;
@Resource
ReachGoal3Mapper reachGoal3Mapper;
@GetMapping("/test")
    public void test() {
        reachGoalService.testBaseMapper("2", reachGoal2Mapper);
        reachGoalService.testBaseMapper("3", reachGoal3Mapper);
}
