How to globally configure `@DateTimeFormat` pattern in Spring Boot?
@britter: thanks.
spring.mvc.date-format= # Date format to use. For instance, dd/MM/yyyy
works fine with
Spring Boot 2.1.0.x
See # SPRING MVC (WebMvcProperties) properties.
UPDATE: But it doen't work for Spring Data Rest params ...
You can use spring.mvc.format.date, spring.mvc.format.time
and spring.mvc.format.date-time
For example:spring.mvc.format.time=HH:mm:ss
spring.mvc.format.date=iso
spring.mvc.format.date-time=iso-offset
as in the example above, you can use shortcuts iso
аnd iso-offset
from spring boot 2.4.1
This is currently not easily possible (e.g. by setting a simple configuration property), see #5523. The best solution I found so far is to register a Formatter<LocalDate>
. This will also work with optional parameters modeled as Optional<LocalDate>
:
@Bean
public Formatter<LocalDate> localDateFormatter() {
return new Formatter<LocalDate>() {
@Override
public LocalDate parse(String text, Locale locale) throws ParseException {
return LocalDate.parse(text, DateTimeFormatter.ISO_DATE);
}
@Override
public String print(LocalDate object, Locale locale) {
return DateTimeFormatter.ISO_DATE.format(object);
}
};
}
It may become possible to set this using a configuration property when my proposal in #9930 has been merged.
