将JSON对象转换为JSON数组

我遇到问题。我的应用程序不会从我的Web服务加载资源，因为它的格式已更改。将JSON对象转换为JSON数组

我的web服务之前返回一个JSON数组是这样的：

[{"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"}]}

这里是我的代码在后端：

@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？

你得到的是一个键/值对，其中关键是

product

和1-元件阵列

[{"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"}]

指www.json.org/javadoc/org/json /JSONObject.html，看看下面的方法：

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

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

修改你的应用程序加载资源应该很容易n ow :)
