How to deserialize JS date using Jackson?

Question

I'm getting a date string from ExtJS in the format:

"2011-04-08T09:00:00"

when i try to deserialize this date, it changes the timezone to Indian Standard Time (adds +5:30 to the time) . This is how i'm deserializing the date:

SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss"); getObjectMapper().getDeserializationConfig().setDateFormat(dateFormat); 

Doing this also doesn't change the timezone. I still get the date in IST:

SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss"); dateFormat.setTimeZone(TimeZone.getTimeZone("GMT")); getObjectMapper().getDeserializationConfig().setDateFormat(dateFormat); 

How do I deserialize the date in the way in which it is coming without the hassles of Timezone?

I found a work around but with this I'll need to annotate each date's setter throughout the project. Is there a way in which I can specify the format while creating the ObjectMapper?

Here's what I did:

public class CustomJsonDateDeserializer extends JsonDeserializer<Date> {     @Override     public Date deserialize(JsonParser jsonParser,             DeserializationContext deserializationContext) throws IOException, JsonProcessingException {          SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");         String date = jsonParser.getText();         try {             return format.parse(date);         } catch (ParseException e) {             throw new RuntimeException(e);         }      }  } 

And annotated each Date field's setter method with this:

@JsonDeserialize(using = CustomJsonDateDeserializer.class)
