无法使用角度和 spring 发射有效请求

在 Spring 天使用角度处理Web服务时我无法对其执行任何操作,因为以下是我的代码@cartRestcontroller

@RestController
@RequestMapping("/rest/cart")
public class CartRestController {
@RequestMapping(value = "/add/{productId}", method = RequestMethod.PUT)
    @ResponseStatus(code = HttpStatus.NO_CONTENT)
    public void addItem(String productId, HttpServletRequest request) {
        String sessionId = request.getSession(true).getId();

        Cart cart = cartService.read(sessionId);

        if (cart == null)
            cart = cartService.create(cart);

        Product product = productService.getProductById(productId);
        System.out.println(product.getName());
        if (product == null)
            throw new IllegalArgumentException("Product does not exist");

        cart.addCartItem(new CartItem(product));

        cartService.update(sessionId, cart);
    }

@ExceptionHandler(Exception.class)
    @ResponseStatus(code = HttpStatus.INTERNAL_SERVER_ERROR, reason = "Please verify your payload")
    public void handleServerErrors(Exception ex) {
        ex.printStackTrace(System.out);
    }

我的控制员为这份工作

var cartApp =   angular.module('cartApp',   []);
cartApp.controller('cartCtrl',  function ($scope, $http)    {
        console.log("Inside Controller");
        $scope.refreshCart  =   function(cartId)    {
                $http.get('/webstore_ecommerce/rest/cart/'+$scope.cartId)
                .success(function(data) {
                        $scope.cart =   data;
                });
        };
        $scope.clearCart    =   function()  {
            $http.delete('/webstore_ecommerce/rest/cart/'+$scope.cartId)
            .success($scope.refreshCart($scope.cartId));

    };

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

    $scope.addToCart = function(productId)  {

            $http.put('/webstore_ecommerce/rest/cart/add/'+productId)
            .success(function(data) {
                    $scope.refreshCart($http.get('webstore_ecommerce/rest/cart/get/cartId'));
                    conslole.log("Sucess, added to cart");
                    alert("Product  Successfully    added   to  the Cart!");
            });
    };
    $scope.removeFromCart   =   function(productId) {
            $http.put('/webstore_ecommerce/rest/cart/remove/'+productId)
            .success(function(data) {
                    $scope.refreshCart($http.get('/webstore_ecommerce/rest/cart/get/cartId'));
            });
    };
});

这就是我现在得到的错误

Edit 如果我使用邮递员发送请求,一切正常 Edit 这是我从stacktrace获得的错误

我的cartRepositiry

@Repository公共类CartRepositiryImpl实现CartRepositiry {

Map<String, Cart> listOfCarts;

    public CartRepositiryImpl() {
        listOfCarts = new HashMap<>();
    }

    @Override
    public Cart create(Cart cart) {
        if (listOfCarts.containsKey(cart.getCartId()))
            throw new IllegalArgumentException(String.format("Cart with id : (%s) already exists", cart.getCartId()));

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

这就是firebug的回报:

“NetworkError:500 - http://localhost:8080/webstore_ecommerce/rest/cart/add/P1235”P1235由于我是新手,请帮我解决这个问题,感谢任何帮助

谢谢

你写了conslole而不是控制台...你最好去睡觉或喝咖啡休息:)

===> conslole.log("Sucess, added to cart");
