json转java实体

1.单个实体转换

    

    String json = "[{\"EmployeeID\":\"1\",\"AttendancePhoto\":\"20150715164240_1\"}]";

    if(json.indexOf("[")!=-1){

        json=json.replace("[", "");

    }

    if(json.indexOf("]")!=-1){

        json=json.replace("]", "");

    }

    AttendanceVO simInfo= new GsonBuilder().create().fromJson(json, AttendanceVO.class);

    System.out.println(simInfo);

 2.List实体转换
  

String json = "[{\"EmployeeID\":\"1\",\"AttendancePhoto\":\"20150715164240_1\"},"+

    "{\"EmployeeID\":\"1\",\"AttendancePhoto\":\"20150715164240_1\"}]";

List<AttendanceVO> list = new GsonBuilder().create()

.fromJson(json, new TypeToken<List<AttendanceVO>>(){}.getType());

System.out.println(list.size());
