1. 求一套完整的JAVA WEB项目的网络购物网站源代码
我这里有一套自己写的仿京东的购物网站，你要吗？
数据库你就自己创建吧，然后商品的图片是varchar类型的，只需要给一个路径就可以了。
也希望能帮到你，望采纳。
2. 用JAVA编写购物系统的代码是什么（急）
算是最简单的吧
package cn.job01;
import java.util.Scanner;
public class Lx07 {
public static void choice() {
System.out.println("登陆菜单 ");
System.out.println("1登陆系统");
System.out.println("2退出");
}
static void choice1() {
System.out.println("购物管理系统>客户信息");
System.out.println("1显示所有客户信息");
System.out.println("2添加客户信息");
System.out.println("3修改客户信息");
System.out.println("4查询客户信息");
}
static void choice2() {
System.out.println("购物管理系统>真情回馈");
System.out.println("1幸运大放送");
System.out.println("2幸运抽奖");
System.out.println("3生日问候");
}
public static void main(String[] args) {
choice();
Scanner input = new Scanner(System.in);
System.out.println("请输入1or2");
int num = input.nextInt();
switch (num) {
case 1:
System.out.println("主菜单");
System.out.println("1客户信息管理");
System.out.println("2购物结算");
System.out.println("3真情回馈");
System.out.println("4注销");
break;
}
System.out.println("选择输入数字");
int num1 = input.nextInt();
switch (num1) {
case 1:
choice1();
break;
case 2:
System.out.println("购物结算");
break;
case 3:
choice2();
break;
case 4:
choice();
break;
}
}
}
3. 购物车的Java代码
import java.util.ArrayList;
import java.util.HashMap;
import java.util.Iterator;public class ShoppingCartManager {
HashMap<String, String> hm=new HashMap<String, String>();
float totlePrice=0;
//添加book到购物车
public void addBook(String bookId,String bookQuantity){
if(hm.containsKey(bookId)){
int value=Integer.parseInt(hm.get(bookId));
value+=Integer.parseInt(bookQuantity);
hm.put(bookId, value+"");
}else{
hm.put(bookId, bookQuantity);
}
}
//修改数量
public void updateQuantity(String bookId,String bookQuantity){
hm.put(bookId, bookQuantity);
}
//获取购物车的所有信息 并计算总价
public ArrayList<BookBean> getShoppingCart(){
ArrayList<BookBean> al=new ArrayList<BookBean>();
Iterator<String> i=hm.keySet().iterator();
String ids="";
BookTableManager btm=new BookTableManager();
while(i.hasNext()){
ids=ids+","+i.next();
}
al= btm.selectByBookIds(ids);
totlePrice=0; //清空总价，防止无限累计
for(int j=0;j<al.size();j++){
BookBean bb=al.get(j);
totlePrice+=bb.getPrice()*Integer.parseInt(getQuantityById(bb.getBookId()+""));
}
return al;
}
//获取总价
public float getTotlePrice(){
return totlePrice;
}
//根据ID获取数量
public String getQuantityById(String id){
String quantity=hm.get(id);
return quantity;
}
//清空购物车
public void clear(){
hm.clear();
}
//删除购物车中的一本书
public void deleteById(String id){
hm.remove(id);
}
}
4. 求一个完整的javaweb项目的购物网站源代码
我这里有几个完整的javaweb商城，一个是仿当当，一个是仿京东，框架采用springmvc和mybatis
严格按照mvc设计模式做的，远超大学的平均水平了
5. 如何使用java实现京东优惠券的功能
你做页面，然后登陆到京东网站？？？？还是你模拟京东的登陆页面？如果是前一种的方式，你永远也登陆不了，数据库是京东设计的，第二种方式都是可行的。
6. java抓取网页优惠券信息那位大神会写帮忙写一下，一直取不到，附上链接
使用jsoup-1.7.3.jar
importjava.io.IOException;
importorg.jsoup.Jsoup;
importorg.jsoup.nodes.Document;
publicclassCrawler{
publicstaticvoidmain(String[]args)throwsIOException{
版Stringurl="你的url";
Documentdoc=Jsoup.connect(url)
.userAgent("Mozilla/5.0(WindowsNT10.0;WOW64)AppleWebKit/537.36(KHTML,likeGecko)Chrome/56.0.2924.87Safari/537.36")
.get();
System.out.println(doc.select("div[class=coupon-info]").text());
}
}
