我試圖做一些非常簡單的事情。我只想在Spring MVC應用程序中顯示JSP頁面上的列表。我GOOGLE了很多，有很多的例子（包括一些在Stackoverflow），但它只是不適合我。我使用的是Maven和Spring 3.2.4。這是我的文件：使用Spring MVC在JSP頁面上未解決的EL表達式顯示列表
Item.java
public class Item
{
private final String value;
public Item(String value)
{
this.value = value;
}
public String getValue()
{
return value;
}
}
MainController.java
@Controller
public class MainController
{
@RequestMapping("/")
public String home(ModelMap map)
{
final List<Item> items = new ArrayList<Item>();
items.add(new Item("Value 1"));
items.add(new Item("Value 2"));
items.add(new Item("Value 3"));
items.add(new Item("Value 5"));
map.addAttribute(items);
return "list";
}
}
的List.jsp

當我運行的AP摺疊，我得到的是：
Naked List
${item.value}
我真的希望我失去了一些非常明顯的配置，這是一個快速簡單的解決方法。
我似乎無法重現你的問題。你能告訴我們你的'Item'類和你的pom.xml嗎？ –
@SotiriosDelimanolis，感謝您花時間嘗試。我已經添加了Item類和我的pom.xml。 –
