将JSON对象转换为JSON数组

Question

我有个问题。我的应用程序无法从我的web服务加载资源，因为它的格式已更改。

在我的web服务像这样返回一个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，我猜：

{"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"}]}

下面是我在后台的代码：

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

我返回一个列表，所以它应该在数组中，对吗？

Answer 1

您得到的是一个键/值对，其中key是

product

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)

修改您的应用程序以加载资源现在应该很容易了:)
