我想顯示產品表中顯示的所有可用產品以顯示在此頁面上。我的jstl核心taglib被添加到頭文件中。jstl標籤<c:forEach不起作用
productList.jsp
<%@ taglib prefix="spring" uri="http://www.springframework.org/tags" %>
<%@include file="header.jsp"%>
<div class="container-wrapper">
<div class="container">
<div class="page-header">
<h1>All Products</h1>
<p class="lead">Checkout all the awesome products available now!</p>
</div>
<table class="table table-striped table-hover">
<thead>
<tr class="bg-success">
<th>Product Code</th>
<th>Product Name</th>
<th>Product Price</th>
<th></th>
</tr>
</thead>
<c:forEach items="${products}" var="product">
<tr>
<td>${product.code}</td>
<td>${product.name}</td>
<td>${product.price}</td>
<td><a href="<spring:url
value="/product/viewProduct/${product.productId}" />"
> <span class="glyphicon glyphicon-info-sign"></span></a></td>
</tr>
</c:forEach>
</table>
<jsp:include page="footer.jsp" />
我ProductController的是返回的產品清單。
ProductController的
@Controller
public class ProductController {
@Autowired
ProductServiceImpl productService;
@RequestMapping(value="addProduct")
public String addProduct(){
return ("addProduct");
}
@RequestMapping(value = "/saveProduct")
public String saveProduct(@ModelAttribute("product") Product productInfo){
productService.sace(productInfo);
return ("addProduct");
}
@RequestMapping(value = "/productList", method = RequestMethod.GET)
public String productList(Model model){
List<Product> productInfoList=productService.productList();
model.addAttribute("products",productInfoList);
return "productList";
}
}
當我運行在調試模式下,我可以清晰的看到產品的刀返回列表,所以沒有數據從數據庫中獲取的問題,這個代碼
。
ProductDao的
@Repository
public class ProductDaoImpl implements ProductDao {
@Autowired
SessionFactory sessionFactory;
Session session;
Transaction tx;
public List<Product> productionList() {
session=sessionFactory.openSession();
List<Product> productList=session.createQuery("from Product").list();
return productList;
}
}
上的pom.xml依賴列表是

當前產品列表頁
請出示你的web.xml也。當servlet規範版本設置得太低時,這通常是一個問題。 – Gimby
