i have a JSP with hyperlink
<table>
<tr>
<td>Product Name : </td>
<td>${product.name}</td>
</tr>
<tr>
<td>Description:</td>
<td>${product.description}</td>
</tr>
<tr>
<td>Price:</td>
<td>${product.price}</td>
</tr>
<tr><td> </td></tr>
<tr>
<td>
<a href="../shopbasket/populateBasket?code=${product.productCode}&name=${categoryName}">Add to shopping basket</a>
</td>
</tr>
<tr><td> </td></tr>
<tr><td> </td></tr>
<tr>
<td>
<table>
<tr>
<td><a href="<c:url value="../index.html"/>">Return to Home Page</a></td>
<td> </td>
<td><a href="<c:url value="/j_spring_security_lo开发者_如何学运维gout"/>">Logout</a>
(<security:authentication property="principal.username" />)
</td>
</tr>
</table>
</td>
</tr>
And the controller
@Controller @SessionAttributes("basket") public class ShopBasketController {
private BasketManager basketManager;
private CustomerManager customerManager;
private CategoryManager categoryManager;
@Autowired
public ShopBasketController(BasketManager basketManager, CustomerManager customerManager, CategoryManager categoryManager) {
this.basketManager = basketManager;
this.customerManager = customerManager;
this.categoryManager = categoryManager;
}
@RequestMapping(value="/basketItems", method=RequestMethod.POST)
public String removeProduct(@ModelAttribute("basket") Basket basket, BindingResult bindingResult, Model model) {
Basket newBasket = ShoppingBasketUtils.removeFromBasket(basket, basketManager);
basketManager.update(newBasket);
model.addAttribute("basket",newBasket);
model.addAttribute("customer", "Sonx"+" Nkuks");
model.addAttribute("totalItems", basketManager.getTotalNumberOfItems(basket));
model.addAttribute("totalPrice", ShoppingBasketUtils.currencyFormat(basketManager.getTotalProductPrice(basket)));
return "basketItems";
}
@RequestMapping("/populateBasket")
public String populateBasket(@RequestParam("code") String productCode, @RequestParam("name") String categoryName, Model model) {
Customer customer = customerManager.getCustomer("Sonx", "Nkuks");
if(customer != null) {
Basket shopBasket = ShoppingBasketUtils.addToBasket(productCode, categoryManager.getCategory(categoryName),
basketManager.getBasket(customer.getReferenceNumber()), basketManager);
basketManager.update(shopBasket);
model.addAttribute("basket",shopBasket);
model.addAttribute("customer", customer.getFirstName()+" "+customer.getLastName());
model.addAttribute("totalItems", basketManager.getTotalNumberOfItems(shopBasket));
model.addAttribute("totalPrice", ShoppingBasketUtils.currencyFormat(basketManager.getTotalProductPrice(shopBasket)));
return "basketItems";
}
model.addAttribute("customer", "test".concat(" test"));
return "/error";
}
}
Then the form ...
<form:form commandName="basket">
<table>
<tr>
<td>
<table>
<tr>
<td>Customer Name : </td>
<td>${customer}</td>
</tr>
</table>
</td>
</tr>
<tr>
<td>
<table width="600" border="1" cellspacing="0" cellpadding="2"
border="0">
<thead>
<tr>
<td>Products:</td>
</tr>
<tr>
<td>Product Name</td>
<td>Product Code</td>
<td>Description</td>
<td>Price</td>
<td>Remove</td>
</tr>
</thead>
<tbody>
<c:forEach items="${basket.products}" var="product">
<tr>
<td>${product.name}</td>
<td>${product.productCode}</td>
<td>${product.description}</td>
<td>${product.price}</td>
<td><form:checkbox path="removeItemCodes" value="${product.productCode}" /></td>
</tr>
</c:forEach>
</tbody>
</table>
</td>
</tr>
<tr>
<td>
<table>
<tr>
<td>Total Price</td>
<td> </td>
<td>${totalPrice}</td>
</tr>
<tr>
<td>Total Items</td>
<td> </td>
<td>${totalItems}</td>
</tr>
</table>
</td>
</tr>
<tr><td> </td></tr>
<tr>
<td><input type="submit" value="Remove Items" /></td>
</tr>
<tr><td> </td></tr>
<tr><td> </td></tr>
<tr>
<td>
<table>
<tr>
<td><a href="<c:url value="../index.html"/>">Return to Home Page</a></td>
<td> </td>
<td><a href="<c:url value="/j_spring_security_logout"/>">Logout</a>
(<security:authentication property="principal.username" />)
</td>
</tr>
</table>
</td>
</tr>
</table>
When i press the link from the first JSP "" the controller succesfully execute the method populateBasket and loads the Form. But when i submit the form, i want it to call the POST method (basketItems)... But it doesn't, pressng the submit button always executes the GET method (populateBasket) .. This doesn't happen if i load the form directly from the index page, it loads successfully . Problem is when coming from that JSP ?
If you want the form to submit to a different URL from the one that was used to retrieve the page, you need to explicitly set the action
on it. Otherwise Spring is going to just fill it in with the current URL.
