从Servlet发送类似数组的Json Response

Question

我正在使用Google json jar从servlet发送Json。我想以类似的模式发送Json。

{
    "Id": "abcde12346",
"Id2": "12039",
    "IdName": "ghh",
    "Employee": [ {
        "EmpCode": "KGM",
        "EmpName": "ABC",
        "Emparrival": "15:35",      
        "Empdeparture": "19:35",        
        "EmpId": "1"
        },
        {
        "EmpCode": "HDW",
        "EmpName": "Haldwani",
        "Emparrival": "15:50",
        "Empdeparture": "19:35",
        "EmpId": "2"
        },
        {
        …
},
...
                ]
}

当前我正在发送类似数据

 json = new Gson().toJson(list);
             response.setContentType("application/json");
             response.getWriter().write(json);

这里的列表是HashMap对象。
