在Java中解析JSON并在UI中排列

我是JAVA新手，以前从未处理过JSON数据。 我必须创建一个新闻桌面应用程序，为此我发送了一个GET 请求一个web地址，我得到如下所示的JSON输出

 ****OUTPUT in JSON****

    {
    "status": "ok",
    "source": "the-hindu",
    "sortBy": "top",
    -"articles": [
    -{
    "author": "AP",
    "title": "Liu Xiaobo, Chinese dissident who won Nobel prize, dies",
    "description": "He succumbed to cancer in a hospital while remaining under 
    police custody.",
    "url": "http://www.thehindu.com/news/international/chinese-nobel-laureate-
    liu-xiaobo-dies/article19271778.ece",

    "urlToImage":"http://www.thehindu.com/news/international/Xiaobo",
    "publishedAt": null
    },

    -{
    "author": "Pavan Dahat",
    "title": "BJP leader beaten for carrying ‘beef’",
    "description": "A video of the incident that went viral on social media, 
    shows the attackers accusing the man of “ killing a cow.”",
    "url": "http://www.thehindu.com/news/national/other-states/man-attacked-
     in-
    nagpur-for-allegedly-carrying-beef/article19269863.ece",
    "urlToImage": "http://www.thehindu.com/news/national/other-
    states/article19269862.ece/ALTERNATES/LANDSCAPE_615/beef1",
    "publishedAt": null
    },

    ]
   }

现在，我必须解析这些JSON数据，并将标题与图像安排在适当的位置。我如何才能做到这一点？

使用jackson2，您可以轻松做到这一点：

首先将jackson2添加为应用程序中的依赖项：

将其保存到数组列表中的示例：

//Declare an array list of the object that you want to use    
private List<YourOwnObject> cart = new ArrayList<>();

//Create an instance of ObjectMapper
ObjectMapper mapper = new ObjectMapper();

//Third pass your json string to the object mapper
this.cart = mapper.readValue(yourJsonResponseString, mapper.getTypeFactory().constructCollectionType(List.class, YourOwnObject.class));

//声明要使用的对象的数组列表
私有列表购物车=新的ArrayList（）；
//创建ObjectMapper的实例
ObjectMapper mapper=新的ObjectMapper（）；
//第三，将json字符串传递给对象映射器
this.cart=mapper.readValue（yourJsonResponseString，mapper.getTypeFactory（）.ConstructionCollectionType（List.class，YourOwnObject.class））；

希望这有帮助！

关于，您可以使用Jackson库解析JSON。你可以看看。
