代码

Map<String,String> map = new HashMap<>();
            map.put("aa","aa");
            map.put("bb","bb");
            map.put("cc","cc");
            Map<String,String> ss = new HashMap<>();
            ss.put("dd","dd");
            ss.put("ee","ee");
            ss.put("ff","ff");
            NutMap nutMap = new NutMap();
            nutMap.setv("itype","1");
            nutMap.setv("map",map);
            nutMap.setv("ss",ss);
            String content = Json.toJson(nutMap);
            System.out.println("--------------content="+content);
            Map<String,String> map1 = Json.fromJsonAsMap(String.class,content);
            System.out.println("--------------"+Json.toJson(map1));

结果：

--------------content={
   "itype": "1",
   "map": {
      "aa": "aa",
      "bb": "bb",
      "cc": "cc"
   },
   "ss": {
      "dd": "dd",
      "ee": "ee",
      "ff": "ff"
   }
}
--------------{
   "itype": "1",
   "map": "",
   "ss": ""
}

我想取出所有的内容，该怎么写？
