List<SpecialTesting> specialTestingFour = baseMapper.selectList(Wrappers.<SpecialTesting>query().lambda()
.in(SpecialTesting::getId, listId)); 

以上述Demo为例,如何查询parentCode为1~9的数据????

List<SpecialTesting> specialTestingFour = baseMapper.selectList(Wrappers.<SpecialTesting>query().lambda()  .eq(SpecialTesting::getType, "parameter")  .in(SpecialTesting::getId, listId)  .or() // 开始or条件组  .eq(SpecialTesting::getParentCode, "1")  .or().eq(SpecialTesting::getParentCode, "2")  .or().eq(SpecialTesting::getParentCode, "3")  .or().eq(SpecialTesting::getParentCode, "4")  .or().eq(SpecialTesting::getParentCode, "5")  .or().eq(SpecialTesting::getParentCode, "6")  .or().eq(SpecialTesting::getParentCode, "7")  .or().eq(SpecialTesting::getParentCode, "8")  .or(
