flavors.stream().map((item) -> { item.setDishId(dishDto.getId()); return item; }).collect(Collectors.toList())这段代码的作用是什么?
这段代码的作用是将菜品的ID设置为每个口味对象的dishId属性,并将修改后的口味对象重新收集到一个新的列表中。通过使用stream()方法和map()方法,我们可以对每个口味对象进行操作并修改其属性值。最后,使用collect()方法将修改后的口味对象收集到一个新的列表中。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
