Gson 关于Array和List的序列化.

关于Gson对于Array和List的 serialize 输出. 都是中括号括起来的.

1Gson gson=new Gson();
2String[] arrays=new String[]{"a","b","c"};
3List<String> list=new ArrayList<String>();
4list.add("listA");
5list.add("listB");
6list.add("listC");
7System.out.println(gson.toJson(arrays));//["a","b","c"]
8System.out.println(gson.toJson(list));//["listA","listB","listC"]

所以需要在deserialize中注意泛型的匹配.

1        String jsonArrayStr="[\"arrayA\",\"arrayB\",\"arrayC\"]";
2        Type arrayType=new TypeToken<String[]>(){}.getType();
3        String[] rstArray=gson.fromJson(jsonArrayStr,arrayType);
4        for (String s : rstArray) {
5            System.out.println(s);//arrayA  //arrayB    //arrayC
6        }
7
8        String jsonListStr="[\"listA\",\"listB\",\"listC\"]";
9        Type listType=new TypeToken<List<String>>(){}.getType();
10        List<String> rstList=gson.fromJson(jsonListStr,listType);
11        for (String s : rstList) {
12            System.out.println(s);//listA   //listB     //listC
13        }
