Large projects of online bookstores (XI) - Reception complete

The main changes

Yesterday's issue is resolved, the user interface is divided into three, the original user page browsing history into the present interface, and more than a modified interface information and shipping address settings interface. At the same time, shopping cart and order code complete, before the bug to be modified. Front display may be considered completed. Worse administrator management interface, as well as filling the database. Oh, yes, I added a new table today, designed to keep the delivery address, and user tables are n-to-1.

New Code

Changes in 11.NewOrderServlet cart

        HttpSession session = request.getSession();
        List<Book>cart = (List<Book>) session.getAttribute("cart");
        if(cart!=null) {
            List<Book>need_del = new ArrayList<Book>();
            BookDao bookDao = new BookDaoImpl();
            for(String book_id:book_ids) {
                for (Book book : cart) {
                    if(book.getBook_id()==Integer.parseInt(book_id)) {
                        need_del.add(book);
                    }
                }
            }
