this is Grid column config
columns: [
{
xtype: 'gridcolumn',
dataIndex: 'afs',
text: 'AFS'
},
{
xtype: 'gridcolumn',
dataIndex: 'date',
text: 'Date',
flex :1
}]
This is my POJO class config for date
@JsonSerialize(using=JsonDateSerializer.class)
public Date getDate() {
return this.date;
}
This is my Controller class
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) {

Gson gson = gsonBuilder.registerTypeAdapter(Date.class, ser).registerTypeAdapter(Date.class, deser).create();
//Gson gson = gsonBuilder.create();
return (T) gson.fromJson(json, type);

NumberFormatException: For input string: "04-22-2011"]You are passing in a value that supposed to be a number but is actually in date format.I think it is where you do :
json.getAsLong(), it expects to have a string like ‘12345654’ but instead it gets the date string.EDIT:
Instead of doing:
try:
