To change the date format of a request parameter field in a DTO while sending in a Spring Boot application, you can use the @DateTimeFormat
annotation provided by Spring Framework.
Here is an example of how to use @DateTimeFormat
to change the date format of a request parameter field in a DTO:
import org.springframework.format.annotation.DateTimeFormat;
public class MyRequestDTO {
@DateTimeFormat(pattern = "dd/MM/yyyy")
private LocalDate date;
// getter and setter
}
In this example, the @DateTimeFormat
annotation is used to specify the pattern for the input date, which is expected to be in the format “dd/MM/yyyy”. The LocalDate
field will be automatically parsed from the input using the specified pattern.
When sending this DTO as a request parameter, the date
field will be automatically converted to a string using the specified format, and included in the request URL as a query parameter.
For example, if you have a MyController
class with a myEndpoint
method that accepts a MyRequestDTO
object as a request parameter, you can send a request to this endpoint like this:
http://localhost:8080/my-endpoint?date=01/05/2023
In this example, the date
field in the MyRequestDTO
object will be set to 2023-05-01
(parsed using the dd/MM/yyyy
format).
