How to register global databinding for LocalDate in spring mvc?

Question

I\'d like to use LocalDate as type in a Servlet created with spring-mvc. The users should be able to provide the date in multiple vali

Answer 1

Well, Even I faced the problem and could not get PropertyEditor to work without initBinder():

Adding below code to each controller would work, I am using springboot v1.5:

@InitBinder
    public void initBinder(WebDataBinder binder) {
        binder.registerCustomEditor(LocalDate.class, 
            new LocalDateEditor());
    }

But bit more easier solution apart from using WebMvcConfigurerAdapter as described by @membersound is to use converters

@Component
public class LocalDateSerializeConverter implements Converter<String, LocalDate> {
    DateTimeFormatter formatter = DateTimeFormatter.ofPattern(AppConstants.DATE_FORMAT_YYYY_MM_DD);

    @Override
    public LocalDate convert(String text) {
        return LocalDate.parse(text, formatter);
    }
}

I still don't know why PropertyEditor does not work. But the following solutions worked.

@Configuration
public class LocalDateConfig extends WebMvcConfigurerAdapter {
    @Override
    public void addFormatters(FormatterRegistry registry) {
        super.addFormatters(registry);
        registry.addFormatterForFieldType(LocalDate.class, new Formatter<LocalDate>() {
            //override parse() and print()
        });
    }
 }
