请问Spring+Thymeleaf+Html 怎么用Session实现分页

我做一个购物车，想实现添加10个物品时，自动分页，11个物品在最顶页面里，刚才的10个物品自动刷新到第2页，该怎么实现呢
Spring
@RequestMapping(path = "/basket/shopping", method = RequestMethod.POST)
public String shopping(Model model, HttpSession session, ItemForm form) {

List<Item> shoppingBasket = new ArrayList<Item>();

if (session.getAttribute("shoppingBasket") != null) {

shoppingBasket = (List<Item>) session.getAttribute("shoppingBasket");

}

session.setAttribute("id", form.getId());

Item item = itemRepository.findOne(Integer.parseInt(form.getId()));

for (int i = 0; i < shoppingBasket.size(); i++) {
Item chek = shoppingBasket.get(i);
if (Integer.parseInt(form.getId()) == chek.getId()) {
return "basket/shopping_basket";
}
}

shoppingBasket.add(item);

session.setAttribute("shoppingBasket", shoppingBasket);

return "basket/shopping_basket";
}

Html

<tr th:each="item: ${session.shoppingBasket}">
<td><a th:href="@{/item/detail/{id}(id=${item.id})}"
th:text="${item.name}"></a></td>
<td th:id="'a' + ${item.id}">1</td>
<td><input type="button" value="个数-1"
th:attr="onclick='subtractNum(' +'a'+ ${item.id} + ');'" /> <input
type="button" value="个数+1"
th:attr="onclick='addNum(' +'a'+ ${item.id} + ');'" /> <input
type="hidden" th:value="${item.stock}" th:id="'c' + ${item.id}" /></td>
<td>
<form th:action="@{/basket/shopping/Delete/} + ${item.id}"
method="post">
<input type="hidden" /> <input type="submit" value="削除"
class="delete" />

</form>
</td>
</tr>
