Java json响应以数字值显示日期 [英] Java json response shows date in numeric value

问题描述

@Data
public class Reponse {

    private String event;

    @Temporal(TemporalType.TIMESTAMP)
    private Date eventDate;

    private Double amount;
}

Json的响应就像

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

在这里，eventDate显示的是数值1540317600000而不是2018-10-23

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

推荐答案

您可以使用 @JsonFormat注释该字段（shape = JsonFormat.Shape.STRING，pattern = yyyy-MM-dd HH：mm）。然后，响应时间格式将类似于 yyyy-MM-dd HH：mm

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;
}
