我正在关注使用Intellij Idea中的spring框架构建电子商务Web应用程序的教程，我对购物车功能有疑问。

功能正常：我可以添加产品但是当我想在购物车中显示产品时没有显示

这是我的代码

CartController 

@Controller
@RequestMapping("/rest/cart")
public class CartController {

    @Autowired
    private CartDao cartDao;

    @Autowired
    private ProductDao productDao;

    @RequestMapping(value = "/{cartId}",headers="Accept=*/*", method = RequestMethod.GET)
    public @ResponseBody Cart read(@PathVariable(value = "cartId") String cartId) {
        return cartDao.read(cartId);
    }

    @RequestMapping(value = "/{cartId}",headers="Accept=*/*", method = RequestMethod.PUT)
    @ResponseStatus(value = HttpStatus.NO_CONTENT)
    public void update(@PathVariable(value = "cartId") String cartId, @RequestBody Cart cart) {
        cartDao.update(cartId, cart);
    }

    @RequestMapping(value = "/{cartId}",headers="Accept=*/*", method = RequestMethod.DELETE)
    @ResponseStatus(value = HttpStatus.NO_CONTENT)
    public void delete(@PathVariable(value = "cartId") String cartId) {
        cartDao.delete(cartId);
    }

    @RequestMapping(value = "/add/{productId}",headers="Accept=*/*", method = RequestMethod.PUT)
    @ResponseStatus(value = HttpStatus.NO_CONTENT)
    public void addItem(@PathVariable (value = "productId") String productId, HttpServletRequest request) {
        String sessionId = request.getSession(true).getId();
        Cart cart = cartDao.read(sessionId);

        if(cart == null) {
            cart = cartDao.create(new Cart(sessionId));
        }

        Product product = productDao.getProductById(productId);
        if(product == null) {
            throw new IllegalArgumentException(new Exception());
        }

        cart.addCartItem(new CartItem(product));

        cartDao.update(sessionId, cart);
    }

    @RequestMapping(value = "/remove/{productId}",headers="Accept=*/*", method = RequestMethod.PUT)
    @ResponseStatus(value = HttpStatus.NO_CONTENT)
    public void removeItem(@PathVariable(value = "productId") String productId, HttpServletRequest request) {
        String sessionId = request.getSession(true).getId();
        Cart cart = cartDao.read(sessionId);

        if(cart == null) {
            cart = cartDao.create(new Cart(sessionId));
        }

        Product product = productDao.getProductById(productId);
        if(product == null) {
            throw new IllegalArgumentException(new Exception());
        }

        cart.removeCartItem(new CartItem(product));

        cartDao.update(sessionId, cart);
    }

    @ExceptionHandler(IllegalArgumentException.class)
    @ResponseStatus(value = HttpStatus.BAD_REQUEST, reason = "Illigal request, please verify your payload")
    public void handleClientError(Exception e) {}


    @ExceptionHandler(Exception.class)
    @ResponseStatus(value = HttpStatus.INTERNAL_SERVER_ERROR, reason = "Internal Server Error")
    public void handleServerError(Exception e) {}

}

The CartDao 

public interface CartDao {

    Cart create(Cart cart);

    Cart read(String cartId);

    void update (String cartId, Cart cart);

    void delete (String cartId);
}

CartDao的实施

@Repository
public class CartDaoImpl implements CartDao{

    private Map<String, Cart> listOfCarts;

    public CartDaoImpl() {
        listOfCarts = new HashMap<String, Cart>();
    }

    public Cart create(Cart cart) {
        if(listOfCarts.keySet().contains(cart.getCartId())) {
            throw new IllegalArgumentException(String.format("Cannot create a cart. A cart with the given id(%) " + "already" + "exists", cart.getCartId()));
        }

        listOfCarts.put(cart.getCartId(), cart);

        return cart;
    }

    public Cart read(String cartId) {
        return listOfCarts.get(cartId);
    }

    public void update(String cartId, Cart cart) {
        if(!listOfCarts.keySet().contains(cartId)) {
            throw new IllegalArgumentException(String.format("Cannot create cart. The cart with the given id(%) " + "does not" + "exist", cart.getCartId()));
        }

        listOfCarts.put(cartId, cart);
    }

    public void delete(String cartId) {
        if(!listOfCarts.keySet().contains(cartId)) {
            throw new IllegalArgumentException(String.format("Cannot delete cart. A cart with the given id(%) " + "does not" + "exists", cartId));
        }

        listOfCarts.remove(cartId);
    }
}

模型（Cart.java）

public class Cart {
    private String cartId;
    private Map<String, CartItem> cartItems;
    private double grandTotal;

    private Cart() {
        cartItems = new HashMap<String, CartItem>();
        grandTotal = 0 ;
    }

    public Cart(String cartId) {
        this();
        this.cartId = cartId;
    }

    public String getCartId() {
        return cartId;
    }

    public void setCartId(String cartId) {
        this.cartId = cartId;
    }

    public Map<String, CartItem> getCartItems() {
        return cartItems;
    }

    public void setCartItems(Map<String, CartItem> cartItems) {
        this.cartItems = cartItems;
    }

    public double getGrandTotal() {
        return grandTotal;
    }

    public void setGrandTotal(double grandTotal) {
        this.grandTotal = grandTotal;
    }

    public void addCartItem (CartItem item) {
        String productId = item.getProduct().getProductId();

        if(cartItems.containsKey(productId)) {
            CartItem existingCartItem = cartItems.get(productId);
            existingCartItem.setQuantity(existingCartItem.getQuantity()+item.getQuantity());
            cartItems.put(productId, existingCartItem);
        } else {
            cartItems.put(productId, item);
        }

        updateGrandTotal();
    }

    public void removeCartItem (CartItem item) {
        String productId = item.getProduct().getProductId();
        cartItems.remove(productId);
        updateGrandTotal();
    }

    public void updateGrandTotal() {
        grandTotal = 0;
        for (CartItem item : cartItems.values()) {
            grandTotal = grandTotal + item.getTotalPrice();
        }
    }
}

controller.js文件，其中包含购物车功能的所有功能

var cartApp = angular.module("cartApp", []);

cartApp.controller("cartCtrl", function ($scope,$http) {

    $scope.refreshCart = function (cartId) {
        $http.get('/eCafeteriaStore/rest/cart/'+$scope.cartId).success(function (data) {
            $scope.cart=data;
        });
    };

    $scope.clearCart = function () {
        $http.delete('/eCafeteriaStore/rest/cart/'+$scope.cartId).success($scope.refreshCart($scope.cartId));
    };

    $scope.initCartId = function (cartId) {
        $scope.cartId = cartId;
        $scope.refreshCart(cartId);
    };

    $scope.addToCart = function (productId) {
          $http.put('/eCafeteriaStore/rest/cart/add/'+productId).success(function (data) {
              $scope.refreshCart($http.get('/eCafeteriaStore/rest/cart/cartId'));
              alert("Le produit a été ajouté au panier")
          });
    };

    $scope.removeFromCart = function (productId) {
        $http.put('/eCafeteriaStore/rest/cart/remove/'+productId).success(function (data) {
            $scope.refreshCart($http.get('/eCafeteriaStore/rest/cart/cartId'));
        });
    };

});

JSP文件viewProduct我在哪里可以看到＆＃34;添加到购物车按钮＆＃34;和＃34;查看购物车＆＃34;按钮

这是cart.jsp。这是添加到购物车的产品应该是什么，我什么也看不见

    </div>
</div>

<script src="<c:url value="/resources/js/controller.js" /> "></script>
<%@include file="/WEB-INF/views/template/footer.jsp"%>

我在标题部分中包含了Angular 

   <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.1/angular.min.js" > </script>

当我尝试调试cart.jsp页面时，我在Chrome " Failed to load resource: the server responded with a status of 406 (Not Acceptable) "

中的开发者工具中收到此消息

这个Apache错误406 

 The resource identified by this request is only capable of generating responses with characteristics not acceptable according to the request "accept" headers.

任何人都可以帮我这个吗
