ここで、グリッドをJavaに送信しているときに問題が発生し、日付解析エラーが発生します。このエラーを解決する方法。私を助けてください。以下は私の回答です。

これは応答です

{"gridData":[{"id":170,"afs":5,"date":"04-22-2011","qty":12,"quantity":11,"shift":"A","sourceLocation":"Office","time":"12:00:00 AM"},{"id":171,"afs":6,"date":"04-22-2011","qty":12,"quantity":11,"shift":"B","sourceLocation":"Office","time":"12:00:00 AM"},{"id":172,"afs":7,"date":"04-22-2011","qty":12,"quantity":11,"shift":"C","sourceLocation":"Office","time":"12:00:00 AM"},{"id":173,"afs":8,"date":"04-22-2011","qty":12,"quantity":11,"shift":"A","sourceLocation":"Office","time":"12:00:00 AM"},{"id":174,"afs":9,"date":"04-22-2011","qty":12,"quantity":11,"shift":"B","sourceLocation":"Office","time":"12:00:00 AM"},{"id":175,"afs":10,"date":"04-22-2011","qty":12,"quantity":11,"shift":"C","sourceLocation":"Office","time":"12:00:00 AM"},{"id":176,"afs":11,"date":"04-22-2011","qty":12,"quantity":11,"shift":"A","sourceLocation":"Office","time":"12:00:00 AM"},{"id":177,"afs":12,"date":"04-22-2011","qty":12,"quantity":11,"shift":"B","sourceLocation":"Office","time":"12:00:00 AM"},{"id":178,"afs":13,"date":"04-22-2011","qty":12,"quantity":11,"shift":"C","sourceLocation":"Office","time":"12:00:00 AM"},{"id":179,"afs":14,"date":"04-22-2011","qty":12,"quantity":11,"shift":"A","sourceLocation":"Office","time":"12:00:00 AM"},{"id":180,"afs":15,"date":"04-22-2011","qty":12,"quantity":11,"shift":"B","sourceLocation":"Office","time":"12:00:00 AM"},{"id":181,"afs":16,"date":"04-22-2011","qty":12,"quantity":11,"shift":"C","sourceLocation":"Office","time":"12:00:00 AM"},{"id":182,"afs":17,"date":"04-22-2011","qty":12,"quantity":11,"shift":"A","sourceLocation":"Office","time":"12:00:00 AM"}],"success":true}

これはグリッド列の構成です

columns: [
            {
                xtype: 'gridcolumn',
                dataIndex: 'afs',
                text: 'AFS'
            },
            {
                xtype: 'gridcolumn',
                dataIndex: 'date',
                text: 'Date',
                flex :1
            }]

これは、日付のPOJOクラス構成です

@JsonSerialize(using=JsonDateSerializer.class)
public Date getDate() {
    return this.date;
}

これは私のコントローラークラスです

 public@ResponseBody String saveGridData(HttpServletRequest request,@RequestParam("grid") String gridData){
    System.out.println("Group Name :"+request.getParameter("groupName"));
    JSONPObject json = new JSONPObject("encode", gridData);
    System.out.println(gridData);
    NewSand[] newSands =    getJsonString(gridData, NewSand[].class);
    for(NewSand newSand: newSands){
        System.out.println("Shift --> " + newSand.getShift());
    }
    return "true";
}

private static <T> T getJsonString(String json,  Class<T> type) throws JsonParseException{

    GsonBuilder gsonBuilder = new GsonBuilder();
    gsonBuilder.serializeNulls();
    JsonSerializer<Date> ser = new JsonSerializer<Date>() {
          public JsonElement serialize(Date src, Type typeOfSrc, JsonSerializationContext 
                     context) {
            return src == null ? null : new JsonPrimitive(src.getTime());
          }
        };

        JsonDeserializer<Date> deser = new JsonDeserializer<Date>() {
          public Date deserialize(JsonElement json, Type typeOfT,JsonDeserializationContext context) throws JsonParseException {
            return json == null ? null : new Date(json.getAsLong());
          }
        };
        Gson gson = gsonBuilder.registerTypeAdapter(Date.class, ser).registerTypeAdapter(Date.class, deser).create();
    //Gson gson = gsonBuilder.create();
    return (T) gson.fromJson(json, type);   
}

例外コードは次のとおりです。

日付解析エラーが発生しました。助けてください。よろしくお願いします。

エラーは非常に明白です。NumberFormatException: For input string: "04-22-2011"]数値であるはずの値を渡していますが、実際には日付形式です。

私はそれがあなたがするところだと思います：json.getAsLong()、それは「12345654」のような文字列を持っていることを期待しますが、代わりにそれは日付文字列を取得します。

編集：

行う代わりに：

new Date(json.getAsLong())

試す：

new Date(json.getAsString())
