java - 如何为 Broadleaf Commerce REST API 设置 JSON 格式 - 包装器成员为空？

Question

我在目录端点上创建了一个新路径。它应该接受产品的 JSON 表示并将其添加到数据库中。

public ProductWrapper insertProduct(HttpServletRequest request, ProductWrapper wrapper)
{
    return wrapper;
}


@RequestMapping(value="product",method=RequestMethod.POST)
public ProductWrapper addProduct(HttpServletRequest request, ProductWrapper wrapper){
    return insertProduct(request, wrapper);
}

但是当我将 JSON 放入消息正文中时。它没有将其保存到我的包装中。我的 JSON 如下所示:

{
  "id": 1,
  "name": "Sudden Death Sauce",
  "longDescription": "As my Chilipals know, I am never one to be satisfied. Hence, the creation of Sudden Death. When you need to go beyond... Sudden Death will deliver! ",
  "retailPrice": {
    "amount": "10.99",
    "currency": "USD"
  },
  "primaryMedia": {
    "id": 101,
    "title": "Sudden Death Sauce Bottle",
    "url": "/cmsstatic/img/sauces/Sudden-Death-Sauce-Bottle.jpg",
    "altText": "primary"
  },
  "active": true,
  "activeStartDate": "2017-01-25T16:32:36.993-0500",
  "manufacturer": "Blair's",
  "defaultCategoryId": 2002,
  "productAttribute": [
    {
      "id": 1,
      "productId": 1,
      "attributeName": "heatRange",
      "attributeValue": "4"
    }
  ],
  "media": [
    {
      "id": 102,
      "title": "Sudden Death Sauce Close-up",
      "url": "/cmsstatic/img/sauces/Sudden-Death-Sauce-Close.jpg",
      "altText": "alt1"
    },
    {
      "id": 101,
      "title": "Sudden Death Sauce Bottle",
      "url": "/cmsstatic/img/sauces/Sudden-Death-Sauce-Bottle.jpg",
      "altText": "primary"
    }
  ]
}

我错过了什么吗？我设置了一个断点，效果很好。包装器已实例化，但所有成员均为空。

您需要使用 @RequestBody 注释 wrapper 参数，并在 @RequestMapping 上添加 accepts :

@RequestMapping(value="product",method=RequestMethod.POST, accepts="application/json")
public ProductWrapper addProduct(HttpServletRequest request, @RequestBody ProductWrapper wrapper){
    return insertProduct(request, wrapper);
}

当您发送请求时，请确保同时发送 Content-Type header ，例如 Content-Type=application/json ，以便 Spring 适本地序列化它.
