shop++改造之ResponseEntity的坑

后台shop++購物車請求的數據是一個Map結構的數據，業務需要要在類似的購物車中加一個套餐。

那么套餐里面就包含商品信息了，覺得不用他的Map了於是封裝了兩個類：

套餐信息顯示類，商品信息顯示類

請求返回數據都正常，但是js就是解析不了后台返回來的數據。也不報錯。
主要原因是SetMealView 類的setMeal原來是一個SetMeal對象，后來改成了String就可以了。

 */
public class SetMealView {

    private String setMeal;//套餐名稱

    private List<ProductDateilView> viewList=new ArrayList<ProductDateilView>();//套餐商品信息


    public SetMealView() {
    }

    public SetMealView(String setMeal, List<ProductDateilView> viewList) {
        this.setMeal = setMeal;
        this.viewList = viewList;
    }

    public String getSetMeal() {
        return setMeal;
    }

    public void setSetMeal(String setMeal) {

    }

    public List<ProductDateilView> getViewList() {
        return viewList;
    }

    public void setViewList(List<ProductDateilView> viewList) {
        this.viewList = viewList;
    }
}

那么請求數據的時候在原來獲取購物車的基礎上進行了改造。

    Map<String, Object> data = new HashMap<>();

        //List<Map<String, Object>> cartItems = new ArrayList<>();//存套餐外的商品
        List<ProductDateilView> cartItems = new ArrayList<>();//存套餐外的商品
        List<SetMealView> setmealist = new ArrayList<>();//setmealist保存套餐內的商品
        //這里做一個小小的改動，要對套餐進行一個分組
        for (CartItem cartItem : currentCart) {
            ProductDateilView productDateilView=new ProductDateilView();
