Java json response shows date in numeric value

@Data
public class Reponse {

    private String event;

    @Temporal(TemporalType.TIMESTAMP)
    private Date eventDate;

    private Double amount;
}

Json response is like

{ 
  event: "transcation',
  eventDate: 1213123434,
  amount: 100
}

Here, eventDate is showing numeric value 1540317600000 instead of 2018-10-23

spring 2.x flipped a Jackson configuration default to write JSR-310 dates as ISO-8601 strings. If you wish to return to the previous behavior, you can add 

spring.jackson.serialization.write-dates-as-timestamps=true

to your application-context configuration file.

You can annotated the field with @JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "yyyy-MM-dd HH:mm"). Then, response time format will be like "yyyy-MM-dd HH:mm"

import com.fasterxml.jackson.annotation.JsonFormat;


public class Reponse {

    private String event;

    @Temporal(TemporalType.TIMESTAMP)
    @JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "yyyy-MM-dd HH:mm")
    private Date eventDate;

    private Double amount;
}

add spring.jackson.serialization.write-dates-as-timestamps=true to your configuration to return to the previous behavior

I suppose you are using rest framework such as spring boot or jersey which in turn 
converts your java date into epoch format before sending it to the client. So while 
sending response you can format you date into the format you want. Please refer 
the code below.

import java.text.SimpleDateFormat;

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.S");
sdf.setLenient(false);
String responseDate = sdf.format(date);
