使用具有多个对象值的 Gson

Question

我有这个 Json 代码：

{
 "term" : {
   "PrincipalTranslations" : {
      "0" : {
            termine:"casa", 
            traduzione:"home"
            }
      "1" :{
             termine:"testa",
             traduzione:"head"
           }
       "2" :{
             termine:"dito",
             traduzione:"finger"
           }
   }
 }
}

How can I deserialize the object 0, 1, 2?? 如果我写对象“零”（并停止）而不是对象 0、1、2，它就可以工作！ 我已经使用了这个实现：

public class Item {    
        private term term;

        public term getTERM() {
                return term;
        }  
}

public class term {
       private PrincipalTranslations PrincipalTranslations;

        public PrincipalTranslations getPrincipalTranslations() {
                return PrincipalTranslations;
        }      
}

public class PrincipalTranslations {
        private zero zero;

        public zero getZero() {
                return zero;
        }
}

public class zero {
        private String termine;

        public String gettermine() {
                return termine;
        }
}

并使用它，它打印（以正确的方式）“casa”

public class MainClass {

    public static void main(String[] args) throws IOException {

        FileReader reader = new FileReader("/home/peppe/test_ff"); 

        Gson gson = new GsonBuilder().create();

        Item p = gson.fromJson(reader, Item.class);
        System.out.print(p.getTERM().getPrincipalTranslations().getZero().gettermine());


        reader.close();
      }
}

如果您想将对象调用为零，请在“Principal Translations”类中使用“SerializedName”注释：http://google-gson.googlecode.com/svn/tags/1.2.3/docs/javadocs/com/google/gson/annotations/SerializedName.html

它看起来像这样：

@SerializedName("0")
public Zero zero;
