  • 假设我们已经创建好了对应的食物类，想要解析网页中的某个食物写入对应类中，以Pizza为例：
/*
* FoodHtmlParser.java
*/package com.example.service;import com.example.model.*;
import org.jsoup.nodes.Document;
import org.jsoup.nodes.Element;
import org.jsoup.select.Elements;
import org.jsoup.Jsoup;import java.io.File;
import java.util.ArrayList;
import java.util.List;public class FoodHtmlParser {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) {String imgUrl = pizzaDiv.selectFirst("img").attr("src");String name = pizzaDiv.selectFirst("h2").text();String weight = pizzaDiv.select("p:contains(Weight)").text().replace("Weight: ", "");String caloriesStr = pizzaDiv.select("p:contains(Calories)").text().replace("Calories: ", "").replace("kcal", "").trim();int calories = Integer.parseInt(caloriesStr);String priceStr = pizzaDiv.select("p.price").text().replace("$", "");double price = Double.parseDouble(priceStr);String radius = pizzaDiv.select("p:contains(Radius)").text().replace("Radius: ", "");String features = pizzaDiv.select("p.features").text().replace("Features: ", "");Pizza pizza = new Pizza();pizza.setName(name);pizza.setWeight(weight);pizza.setCalories(calories);pizza.setRadius(radius);pizza.setPrice(price);pizza.setFeatures(features);pizza.setImgUrl(imgUrl);pizzas.add(pizza);}} catch (Exception e) {e.printStackTrace();}return pizzas;}
}
  • 其余的食物类型同理：
    public List<FrenchFries> parseFrenchFriess(String filePath) throws java.io.IOException {List<FrenchFries> frenchFriesList = new ArrayList<>();Document doc = Jsoup.parse(new File(filePath), "UTF-8");Elements friesDivs = doc.select("div.french-fries");for (Element friesDiv : friesDivs) {String imgUrl = friesDiv.selectFirst("img").attr("src");String name = friesDiv.selectFirst("h2").text();String weight = friesDiv.select("p:contains(Weight)").text().replace("Weight: ", "");String caloriesStr = friesDiv.select("p:contains(Calories)").text().replace("Calories: ", "").replace("kcal", "").trim();int calories = Integer.parseInt(caloriesStr);String priceStr = friesDiv.select("p.price").text().replace("$", "");double price = Double.parseDouble(priceStr);String thickness = friesDiv.select("p:contains(Thickness)").text().replace("Thickness: ", "");String features = friesDiv.select("p.features").text().replace("Features: ", "");FrenchFries frenchFries = new FrenchFries();frenchFries.setName(name);frenchFries.setWeight(weight);frenchFries.setCalories(calories);frenchFries.setThickness(thickness);frenchFries.setPrice(price);frenchFries.setFeatures(features);frenchFries.setImgUrl(imgUrl);frenchFriesList.add(frenchFries);}return frenchFriesList;}public List<FriedChicken> parseFriedChickens(String filePath) throws java.io.IOException {List<FriedChicken> friedChickenList = new ArrayList<>();Document doc = Jsoup.parse(new File(filePath), "UTF-8");Elements friedChickenDivs = doc.select("div.fried-chicken");for (Element friedChickenDiv : friedChickenDivs) {String imgUrl = friedChickenDiv.selectFirst("img").attr("src");String name = friedChickenDiv.selectFirst("h2").text();String weight = friedChickenDiv.select("p:contains(Weight)").text().replace("Weight: ", "");String caloriesStr = friedChickenDiv.select("p:contains(Calories)").text().replace("Calories: ", "").replace("kcal", "").trim();int calories = Integer.parseInt(caloriesStr);String priceStr = friedChickenDiv.select("p.price").text().replace("$", "");double price = Double.parseDouble(priceStr);String spiciness = friedChickenDiv.select("p:contains(Spiciness)").text().replace("Spiciness: ", "");String features = friedChickenDiv.select("p.features").text().replace("Features: ", "");FriedChicken friedChicken = new FriedChicken();friedChicken.setName(name);friedChicken.setWeight(weight);friedChicken.setCalories(calories);friedChicken.setSpiciness(spiciness);friedChicken.setPrice(price);friedChicken.setFeatures(features);friedChicken.setImgUrl(imgUrl);friedChickenList.add(friedChicken);}return friedChickenList;}
  • 注意： Jsoup的parse方法需要throw Exception，若不抛出异常会导致编译错误。
