首先、建包 com.puckasoft.shopping.po 下面写一个product
如下
package com.puckasoft.shopping.po;
import java.io.Serializable;
public class Product implements Serializable {
private String id;
private String name;
private Double price;
private int num;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Double getPrice() {
return price;
}
public void setPrice(Double price) {
this.price = price;
}
public int getNum() {
return num;
}
public void setNum(int num) {
this.num = num;
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
}
包 package com.puckasoft.shopping.servlet 下面写servlet
package com.puckasoft.shopping.servlet;
import java.io.IOException;
import java.io.PrintWriter;
import java.util.HashMap;
import java.util.Map;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import com.puckasoft.shopping.po.Product;
public class shoppingServlet extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
String id = request.getParameter("id");
String name = request.getParameter("name");
String price = request.getParameter("price");
String num = request.getParameter("num");
Product p = new Product();
p.setId(id);
p.setName(name);
p.setPrice(Double.parseDouble(price));
p.setNum(1);
Map<String, Product> map = (HashMap<String, Product>) request.getSession().getAttribute("showMap");
if(map == null){
map = new HashMap<String,Product>();
}
if(map.containsKey(id)){
p = map.get(id);//获得map中已经存在的商品
p.setNum(p.getNum()+1);
}else{
map.put(id, p);
}
request.getSession().setAttribute("showMap",map);
request.getRequestDispatcher("/shoppList.jsp").forward(request, response);
return;
}
package com.puckasoft.shopping.servlet;
import java.io.IOException;
import java.io.PrintWriter;
import java.util.HashMap;
import java.util.Map;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import com.puckasoft.shopping.po.Product;
public class DeleteManyServlet extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
String[] ids = request.getParameterValues("id");
Map map = (HashMap)request.getSession().getAttribute("showMap");
for (String str : ids) {
Product p = (Product) map.get(str);
if(p.getNum()>1){
p.setNum(p.getNum()-1);
}else{
map.remove(str);
}
}
request.getRequestDispatcher("/shoppList.jsp").forward(request, response);
return;
}
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
doGet(request, response);
}
}
