能把简单购物车的代码发我下吗

一个EJB例子如下（购物车） import java.util.*; import javax.ejb.Stateful; import javax.ejb.*; @Stateful(mappedName="cart") public class CartBean implements Cart{ String customerName; String customerId; List<String> contents; //ArrayList<String> contents; public void initialize(String person) throws BookException { if (person == null) { throw new BookException("不允许没有用户！"); } else { customerName = person; } customerId = "0"; contents = new ArrayList<String>(); } public void initialize(String person, String id) throws BookException { if (person == null) { throw new BookException("不允许没有用户！"); } else { customerName = person; } IdVerifier idChecker = new IdVerifier(); if (idChecker.validate(id)) { customerId = id; } else { throw new BookException("无效的ID: " + id); } contents = new ArrayList<String>(); } public void addBook(String title) { contents.add(title); } public void removeBook(String title) throws BookException { boolean result = contents.remove(title); if (result == false) { throw new BookException(title + " 不在购物车中。

"); } } public List<String> getContents() { return contents; } @Remove() public void remove() { contents = null; } }
