关于JSTL标签

<% } else {
List list = cart.getProductsList();
for (int i = 0; i < list.size(); i++) {
CartItem item = (CartItem) list.get(i);
}
把这些脚本表达式换成LSTL标签体。。谢谢。。

Answer 1

将cart.getProductsList()存储到session中，获得实体类entity
<c:if>
<c:foreach var="list" item="sessionScope.list">
${entity.属性}
</c:foreach>
</c:if>

你在action中设置list
request.setAttribute("item",集合)；
jsp中
<c:forEach items="${item}" var="item" scope="request">
${item.属性}
</c:forEach>

c:foreach标签

Answer 4

<c:forEach items="${cart}" var="item">
${item.nidedongxi}
</c:forEach>
