Question

我遇到了问题。我的应用程序不会从我的Web服务加载资源，因为它的格式已经更改。

在我的Web服务返回这样的JSON数组之前：

[{"productid":2,"sku":"SKU-2","productname":"SMART NEW","productdesc":"description","category":"default category","price":2000.1,"picture":"http://10.23.20.50:8080/msos-ws/images/products/smart.gif","remarks":"remarks"}]

现在它返回一个JSON对象我想：

{"product":[{"category":"default category","picture":"http://localhost:8080/msos-ws/images/products/smart.gif","price":"480.0","productdesc":"Dragon Flash Disk (Special)","productid":"7","productname":"Kingston 8GB","remarks":"remarks","sku":"SKU-7"}]}

这是我在后端的代码：

@GET
@Override
@Produces("application/json")
public List<Product> findAll() {
        return prodManager.getProducts();
}

我正在返回一个List，所以它应该在数组中，对吗？

Answer 1

你得到的是一个键/值对，其中键是

product

和1元素数组是

[{"category":"default category","picture":"http://localhost:8080/msos-ws/images/products/smart.gif","price":"480.0","productdesc":"Dragon Flash Disk (Special)","productid":"7","productname":"Kingston 8GB","remarks":"remarks","sku":"SKU-7"}]

参考www.json.org/javadoc/org/json/JSONObject.html，看看以下方法：

public java.lang.Object get(java.lang.String key)

public JSONObject put(java.lang.String key,
                  java.util.Collection value)

现在，修改您的应用以加载资源应该很简单：）

将JSON对象转换为JSON数组
