Java Date Time – How to build SpringBoot RestApi – Post/Get request with Java Date Time using Jackson and Make Query with Spring JPA example

[no_toc]
In the tutorial, we build a SpringBoot RestAPIs example that post/get data with java.util.Date time and save it to MySQL/PostgreSQL database using Spring JPA. Working with Java Date Time is an exciting part but also not easy task, fortunately we have the supporting from utilities of Jackson lib, now the job can be done in an easy way.

Let’s do details by steps!

Format Java Date Time with Jackson

Set the Format with @JsonFormat

With the @JsonFormat annotation of Jackson, we can use it to format a specific field in Java model:

public class DateTimeModel {	
    
    @JsonFormat(pattern="yyyy-MM-dd")
    private Date date;
    
    @JsonFormat(pattern="yyyy-MM-dd HH:mm:ss")
    private Date datetime;
	
	...
}

Set TimeZone with @JsonFormat

For setting Time Zone, we use timezone attribute of the @JsonFormat:

@JsonFormat(pattern="yyyy-MM-dd HH:mm:ss", timezone="Europe/Paris")
private Date datetimewithzone;

Set Default Format

We can configure a default format & time-zone for all dates in application.properties:
