jsoup解析本地html网页到本地2

• 在之前的jsoup解析本地html网页到本地中，虽然可以实现不同食物的解析，但是每个食物单独写一个方法实在太麻烦了
• 注意到所有食物均属于Food的子类，且解析方法中有许多重复代码
• 可将Food food以及Element foodDiv这两个方法中重复的参数作为通用方法的参数，提取公用方法：

// 提取公共解析逻辑到独立方法
    private void parseCommonFields(Element foodDiv, Food food) {
        String imgUrl = Objects.requireNonNull(foodDiv.selectFirst("img")).attr("src");
        String name = Objects.requireNonNull(foodDiv.selectFirst("h2")).text();
        String weight = foodDiv.select("p:contains(Weight)").text().replace("Weight: ", "");
        String caloriesStr = foodDiv.select("p:contains(Calories)").text()
                .replace("Calories: ", "")
                .replace("kcal", "").trim();
        int calories = Integer.parseInt(caloriesStr);
        String priceStr = foodDiv.select("p.price").text().replace("$", "");
        double price = Double.parseDouble(priceStr);
        String features = foodDiv.select("p.features").text().replace("Features: ", "");

        food.setName(name);
        food.setWeight(weight);
        food.setCalories(calories);
        food.setPrice(price);
        food.setFeatures(features);
        food.setImgUrl(imgUrl);
    }

然后，每个食物只需要调用公共方法，并提取自己的特有部分即可：

1. Pizzas:

public List<Pizza> parsePizzas(String filePath) {
        List<Pizza> pizzas = new ArrayList<>();
        try {
            Document doc = Jsoup.parse(new File(filePath), "UTF-8");
            Elements pizzaDivs = doc.select("div.pizza");
            for (Element pizzaDiv : pizzaDivs) {
                Pizza pizza = new Pizza();
                parseCommonFields(pizzaDiv, pizza); // 调用公共解析方法

                // 只处理Pizza特有的字段
                String radius = pizzaDiv.select("p:contains(Radius)").text().replace("Radius: ", "");
                pizza.setRadius(radius);

                pizzas.add(pizza);
            }
        } catch (Exception e) {
            System.out.println("解析Pizza数据失败" + e.getMessage());
        }
        return pizzas;
    }

2. FrenchFries:

public List<FrenchFries> parseFrenchFriess(String filePath) {

        List<FrenchFries> frenchFriesList = new ArrayList<>();
        try {
            Document doc = Jsoup.parse(new File(filePath), "UTF-8");

        Elements friesDivs = doc.select("div.french-fries");

        for (Element friesDiv : friesDivs) {
            FrenchFries frenchFries = new FrenchFries();
            parseCommonFields(friesDiv, frenchFries); // 调用公共解析方法

            // 只处理FrenchFries特有的字段
            String thickness = friesDiv.select("p:contains(Thickness)").text().replace("Thickness: ", "");
            frenchFries.setThickness(thickness);

            frenchFriesList.add(frenchFries);
        }
        } catch (IOException e) {
            throw new RuntimeException(e);
        }
        return frenchFriesList;
    }

3. FriedChicken:

public List<FriedChicken> parseFriedChickens(String filePath) {
        List<FriedChicken> friedChickenList = new ArrayList<>();
        try {
            Document doc = Jsoup.parse(new File(filePath), "UTF-8");

        Elements friedChickenDivs = doc.select("div.fried-chicken");

        for (Element friedChickenDiv : friedChickenDivs) {
            FriedChicken friedChicken = new FriedChicken();
            parseCommonFields(friedChickenDiv, friedChicken); // 调用公共解析方法

            // 只处理FriedChicken特有的字段
            String spiciness = friedChickenDiv.select("p:contains(Spiciness)").text().replace("Spiciness: ", "");
            friedChicken.setSpiciness(spiciness);

            friedChickenList.add(friedChicken);
        }
        } catch (IOException e) {
            throw new RuntimeException(e);
        }

        return friedChickenList;
    }
