ssm框架中界面取值,实体类中包含List怎么取值?

[qq_25460127]

jsp界面
<c:forEach items="${requestScope.cardsel}" var="card">
<tr>
<%-- <c:forEach items="${cardsel.cardTypes}" var="ty"> --%>

<td>${card.cardTypes.cardTypeName}</td>
<td>${card.cardTypes.cardPrice}</td>
<%-- </c:forEach> --%>

<c:forEach items="${cardsel.shopHistories }" var="sh">

<td>${sh.userId}</td>
<td>${sh.buyNum}</td>
</c:forEach>

<%-- <td>${card.cardState.cardStateId}</td> --%>
<td>${card.cardTotal}</td>
<td></td>
</tr>
</c:forEach>
controller层
@RequestMapping("/getAllHistory")
private String getAllHis(Model model) {
System.out.println("123");
List<Card> cardsel = cardSelServiceImpl.getAllSelCard();
/*
for (int i = 0; i < cardsel.size(); i++) {
System.out.println(cardsel.get(i).getShopHistories().get(i).getShopTime());
}*/
System.out.println(cardsel.size());
System.out.println(cardsel);
model.addAttribute("cardsel",cardsel);
return "admin/CardSales";
}

请问各位大神,这个界面取值我是不是写错了,具体应该怎么写呢,谢谢?刚学框架,很多不懂,谢谢!
