在這裏我得到問題，同時提交網格到Java我得到日期解析錯誤。如何解決這個錯誤。請幫幫我。以下是我的迴應。Json數據解析錯誤
這是響應
{"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}
這是格列配置
columns: [
{
xtype: 'gridcolumn',
dataIndex: 'afs',
text: 'AFS'
},
{
xtype: 'gridcolumn',
dataIndex: 'date',
text: 'Date',
flex :1
}]
這是我的POJO類配置日期
@JsonSerialize(using=JsonDateSerializer.class)
public Date getDate() {
return this.date;
}
這是我的控制器類
[email protected] 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);
}

我得到日期解析錯誤，請幫我在此先感謝。
這是正確的。我們想將給定的字符串轉換成Java的Date對象，但它提供了上述例外。應該做些什麼以便它將「04-22-2011」轉換爲Java的Date對象。 – Mayur
