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.

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

所以需要在deserialize中注意泛型的匹配.

        String jsonArrayStr="[\"arrayA\",\"arrayB\",\"arrayC\"]";
        Type arrayType=new TypeToken<String[]>(){}.getType();
        String[] rstArray=gson.fromJson(jsonArrayStr,arrayType);
        for (String s : rstArray) {
            System.out.println(s);//arrayA  //arrayB    //arrayC
        }

        String jsonListStr="[\"listA\",\"listB\",\"listC\"]";
        Type listType=new TypeToken<List<String>>(){}.getType();
        List<String> rstList=gson.fromJson(jsonListStr,listType);
        for (String s : rstList) {
            System.out.println(s);//listA   //listB     //listC
        }
