如何在对象映射器中将时间戳映射到日期

Question

Right now I am mapping my timestamp to date using object mapper, but this is turning my date object's date to something like this, if timestamp is 1359657000, then it's date should be 01/31/2013, but it is showing me date as 01/31/1970, so I didn't get it what is the issue with this approach.

public class Abcd{ 
   private Date year
 }

And now I get this json

{
"data":
{
"fromDate": 1335810600"
}
}

and when I map it like this from Object Mapper

ObjectMapper mapper =new Mapper();
mapper.readValue(data,Abcd.class);

now the value of year is coming as 31st Dec 1970, although it should be coming 31st Dec 2013

Not sure if I really understand your issue, but in most of situations you don't want to deal with timestamps:

mapper.disable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS);

Then you can define the format of your Date :

@JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "dd-MM-yyyy")
public Date date;
