当前使用版本(必须填写清楚，否则不予处理)

3.1.2

该问题是怎么引起的？(最新版上已修复的会直接close掉)

BaseEntity中有parentIds等属性；ChildEntity继承BaseEntity;在BaseService, T extends BaseEntity\> extends ServiceImpl中使用 QueryWrapper qw = new QueryWrapper<>(); qw.lambda().like(T::getParentIds,entity.getId()); baseMapper.selectList(qw); 查询时抛出can not find lambda cache for this property [parentIds] of entity [BaseEntity]的异常

调试发现AbstractLambdaWrapper的getColumn方法中56行得到的aClass是父类BaseEntity

重现步骤
