않습니다이 내 컨트롤러 클래스 날짜

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

내 POJO 클래스 설정입니다

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); 
}

내가 무엇입니까 날짜 구문 분석 오류가 사전에 나에게 감사를 도와주세요.

Answer 1

오류는 매우 명확합니다. NumberFormatException: For input string: "04-22-2011"] 숫자가되어야하지만 실제로는 날짜 형식 인 값을 전달하고 있습니다.

내가 생각하는 곳은 json.getAsLong()이고 '12345654'와 같은 문자열이 있어야하지만 대신 날짜 문자열을 가져옵니다.

편집 : 일을 대신

:

new Date(json.getAsLong()) 

시도 : 맞습니다

new Date(json.getAsString())
