Dates with Swagger and Spring Boot — 02 April, 2020

When using a date parameter in a API call with a Swagger generated Controller interface I noticed some problems concerning the date format.

I was struggling to find a solution to receive the dates without adding the @DateTimeFormat(iso = DateTimeFormat.ISO.DATE_TIME) annotation to the date parameter, which defeats the purpose of using generated code.

The solution I found here is to add a formatter to a WebMvcConfigurer class.


public class RestConfiguration extends WebMvcConfigurerAdapter {

    public void addFormatters(FormatterRegistry registry) {
        DateTimeFormatterRegistrar registrar = new DateTimeFormatterRegistrar();
