gson如何将json映射到POJO，其中json键有2个空格分隔的单词

Question

我有一个json格式的yelp数据集。我正在使用gson映射到POJO。但是，某些键如"Drive-Thru", "Good For"是连字符或空格分隔。如何为这些类型的键映射POJO类？

{
    "business_id":"5UmKMjUEUNdYWqANhGckJw",
    "attributes":{
        "Take-out":true,
        "Drive-Thru":false,
        "Good For":{
            "dessert":false,
            "latenight":false
        },
        "Caters":false,
        "Noise Level":"average",
        "Has TV":false,
        "Good For Groups":true,
        "Wi-Fi":"free",
        "Price Range":1
    },
    "type":"business"
}

我有以下pojo但是对于特殊键类型

，这会返回null

public class BusinessPojo {    
   private String type;
   private String business_id;
   private BusinessAttributes attributes;
// getters and setters
}

public class BusinessAttributes {
    private boolean takeOut;
    private boolean driveThru;
    private boolean Caters;
    private String noiseLevel;
    private boolean hasTV;
    private String wiFi;
    private boolean goodforGroups;
    private int priceRange;
    private BusinessGoodFor goodFor;
//getters and setters
}

public class BusinessGoodFor {
    private boolean dessert;
    private boolean latenight;
//getters and setters
}

Gson提供了“序列化名称”注释：

public class BusinessAttributes {

  @SerializedName("Take-out")
  private boolean takeOut;

等...
