公共静态RecipeIndicatorsDto配方指标Dto（RecipeIndicator配方指标，订购单）{ 如果（recipeIndicator！= null && order！= null）{ RecipeIndicatorsDto recipeIndicatorsDto =新的RecipeIndicatorsDto（）; recipeIndicatorsDto.setVerificationStatus（recipeIndicator.getVerificationStatus（））;
recipeIndicatorsDto.setUploadTime（recipeIndicator.getUploadTime（））; recipeIndicatorsDto.setRemark（order.getRemark（））; recipeIndicatorsDto.setUseDays（order.getUseDays（））;

Answer 1

DtoFactory::recipeIndicatorsDto是对静态方法的方法引用，该方法需要一个RecipeIndicator参数和一个Order参数。由于您将其传递给map的{{1}}，因此只有Stream<RecipeIndicator>实例可用。

您可以改用lambda表达式：

RecipeIndicator

我不确定要将哪个.map(recipeIndicator -> DtoFactory.recipeIndicatorsDto(recipeIndicator, qOrder))实例传递给它。我猜可能是Order。
