无法使用GSON将JSON字符串转换为JAVA对象

我有一个json文件，其中保存了特定通道的计划。现在，我想使用gson将string转换为java对象。我知道这很简单，但是我对字符串的结构感到困惑。这是我的JSON字符串格式：无法使用GSON将JSON字符串转换为JAVA对象

{ 
    "date": "28022014", 
    "channelName": "star-movies", 
    "listOfShows": [ 
    {

At that point, Will Turner (Orlando Bloom), her would-be suitor, seeks the help of Captain Jack Sparrow (Johnny Depp), a notorious conman. But then, Jack has his own reasons for hunting down Barbossa and his crew. They have stolen Sparrow\u0027s ship, The Black Pearl." 
     } 
    }, 
    { 
     "showTitle": "Fillers", 
     "showTime": "03:30:00", 
     "showThumb": "http://tv.burrp.com/images/s/e/i/eims7nmh_1fwv_1_75.jpg",

     "Language:": "English", 
     "Show Type:": "Promo/Filler", 
     "Show Description": "It\u0027s a series featuring film based program." 
     } 
    }, 
    .... 
    ... 
    }] 
}

这是我想出了类结构：

我无法弄清楚如何物化在清单showDetails？由于它的主要价值对之间有空间......？我在这里错过了什么吗？或者有没有解决方法？

目前尚不清楚你的问题是什么。在Java中建模JSON时遇到问题吗？或者在尝试反序列化时遇到一些错误？如果你问的是建模，我会建议使用非结构化的Map，因为它看起来像是可变的键值对。 – chrylis

是的，建模是，在这种情况下'maps'如何工作？ – faizanjehangir

..并'gson'支持'地图'？ – faizanjehangir

你有两种选择;

看起来像showDetails可以有很多不同的东西在里面。您可以映射出每一个可能的一个，如果你知道它们是什么：

public class ShowDetails { 

    @SerializedName("IMDB Rating") 
    String imdbRating; 
    @SerializedName("Repeats on:") 
    String repeatsOn; 
    // etc , etc 

}

，然后添加到您的Show类：

... 
ShowDetails showDetails; 
...

但是，这可能有点疯狂，这取决于如何许多事情可以在那里，或者如果你不知道所有的可能性。选项B是简单，使用Map<String, String>：

public class Show { 

    private String showTitle; 
    private String showTime; 
    private String showThumb; 
    private Map<String, String> showDetails; 
    // ... 
}

键/在你的JSON值对将被放置在地图上的...键/值对。

您将ShowDetails设置为不同的类，并在Show类中具有ShowDetails属性。要使用空格和冒号符号来引用属性，请使用anotations @“key”。

在这种情况下不起作用，因为该对象是关于该节目的随机分组的琐事。我认为'Map '是最好的。 – chrylis
