Question

我从弹簧控制器得到了错误的请求问题。（原因：客户端发送的请求在语法上是不正确的。）以下是我的休息电话：

请求的有效负载：

categoty: "Game"
itemDescription: "adas"
itemDiscount: 1
itemName: "asdas"
itemPrice: 1
itemQuantity: 1

休息方法

 @RequestMapping(value="/addItem", method = RequestMethod.POST,headers="Accept=application/json")
 public  @ResponseBody String createItem(@RequestBody Item item) {

     ItemDAO itemDAO=new ItemDAO(item);      

     try{
         itemDAO.createProduct();
         return "Success";
     }catch(Exception e){  
         System.out.println("Exception occured in item update");
         e.printStackTrace();
         return "Exception occured in item add";
     }  

 }

模型（仅属性）

@Entity  
@Table(name= "Item")
public class Item {

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    @Column(name="id")
    private int id; 
    private String itemName,itemDescription,categoty;   
    private double itemPrice;
    private float itemDiscount;
    private int itemQuantity;
}

标记

      <p class="{{errorClass}}">{{newProductError}}</p>

          </div>
        </div>
      </form>
  </div>

服务

addItem: function(item){
    return $http({
        method : 'POST',
        url : '/Ecomm-Java-Backend/item/addItem',
        data: item,
        heades:{
            'Content-type': 'application/json'
        }
    }).success(function(result){
        console.log(result.length);
        console.log("result success "+ result);
        return result;
    }).error(function(err){
        console.log("result success "+ err);
        return err;
    });     
}

当我调用其余的电话时，我收到了错误的请求错误。

这可能是什么问题？任何帮助都会受到赞赏。

Answer 1

在Spring控制器中试试这个

@RequestMapping(value="/addItem", method = RequestMethod.POST,consumes=MediaType.APPLICATION_JSON_VALUE)
     public  @ResponseBody String createItem(@RequestBody Item item) {

         ItemDAO itemDAO=new ItemDAO(item);      

         try{
             itemDAO.createProduct();
             return "Success";
         }catch(Exception e){  
             System.out.println("Exception occured in item update");
             e.printStackTrace();
             return "Exception occured in item add";
         }  

     }

这在您的客户端

    addItem: function(item){
        return $http({
            method : 'POST',
            url : '/Ecomm-Java-Backend/item/addItem',
            data: {
     categoty: "Game" ,
     itemDescription: "adas", 
     itemDiscount: 1 ,
     itemName: "asdas",
     itemPrice: 1,
     itemQuantity: 1
// get values from item object
},
            headers : { 'Accept': 'application/json',
                'Content-Type': 'application/json'
            }
        }).success(function(result){
            console.log(result.length);
            console.log("result success "+ result);
            return result;
        }).error(function(err){
            console.log("result success "+ err);
            return err;
        });     
    }

Answer 2

终于解决了将json数据更改为

categoty: "Game"
description: "test1"
discount: 10
name: "Test"
price: 10
quantity: 10

但仍然无法弄清楚为什么会有效...
