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'));
});
};
});
和我的addTocart按钮

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:)
