优化这段代码：public void fixedSpProduct(List<CrmSpProduct> crmSpProductList,Long spApplyId) { if (CollectionUtils.isNotEmpty(crmSpProductList)) { Map<String,Object> map = new HashMap<>(); map.put("SP_APPLY_ID",spApplyId); List<CrmSpProduct> list = this.getBaseMapper().selectByMap(map); if (CollectionUtils.isNotEmpty(list)){ crmSpProductMapper.deleteByMap(map); } for (CrmSpProduct c : crmSpProductList){ c.setSpApplyId(spApplyId); } super.saveOrUpdateBatch(crmSpProductList); } else { throw new BusinessRuntimeException("当前没有任何产品清单，操作失败"); } }

可以考虑使用批量操作来优化代码：

public void fixedSpProduct(List<CrmSpProduct> crmSpProductList,Long spApplyId) {
  if (CollectionUtils.isEmpty(crmSpProductList)) {
    throw new BusinessRuntimeException("当前没有任何产品清单，操作失败");
  }

  Map<String,Object> map = new HashMap<>(); 
  map.put("SP_APPLY_ID",spApplyId); 
  crmSpProductMapper.deleteByMap(map); 

  for (CrmSpProduct c : crmSpProductList){
    c.setSpApplyId(spApplyId);
  }

  super.saveOrUpdateBatch(crmSpProductList);
}
