Spring – Why failed to convert from string to Date in this case

springspring-mvc

I try to convert from String to Date by doing this:

Form:

   <tr>
        <td><form:label path="dateOfBirth" cssErrorClass="error"><spring:message
                code="account.dob"/></form:label></td>
        <td><form:input path="dateOfBirth" type="date"/></td>
        <td><form:errors path="dateOfBirth"/></td>
    </tr>

in configuration class

import org.springframework.format.datetime.DateFormatter
// .....

@Configuration
@EnableWebMvc
@ComponentScan(basePackages = { "..." })
public class WebMvcContextConfiguration extends WebMvcConfigurerAdapter {

    //....
    @Override
    public void addFormatters(FormatterRegistry registry) {
        registry.addFormatter(new DateFormatter("yyyy-MM-dd"));
    }
}

The input value return correct string format for date

enter image description here

But it keep reporting an error

Failed to convert property value of type java.lang.String to required
type java.util.Date for property dateOfBirth; nested exception is
org.springframework.core.convert.ConversionFailedException: Failed to
convert from type java.lang.String to type java.util.Date for value
1999-01-01; nested exception is java.lang.IllegalArgumentException:
Unable to parse 1999-01-01

What did i probably miss here?

UPDATE:

My validator

 @Override
    public void validate(Object target, Errors errors) {
        ValidationUtils.rejectIfEmpty(errors, "username", "required", new Object[] { "Username" });
        ValidationUtils.rejectIfEmpty(errors, "password", "required", new Object[] { "Password" });
        ValidationUtils.rejectIfEmpty(errors, "emailAddress", "required", new Object[] { "Email address" });
        ValidationUtils.rejectIfEmpty(errors, "address.street", "required", new Object[] { "Street" });
        ValidationUtils.rejectIfEmpty(errors, "address.city", "required", new Object[] { "City" });
        ValidationUtils.rejectIfEmpty(errors, "address.country", "required", new Object[] { "Country" });

        if (!errors.hasFieldErrors("emailAddress")) {
            Account account = (Account) target;
            String email = account.getEmailAddress();
            if (!email.matches(EMAIL_PATTERN)) {
                errors.rejectValue("emailAddress", "invalid");
            }
        }
    }

My handler

@RequestMapping(method = { RequestMethod.POST, RequestMethod.PUT })
public String handleRegistration(@Valid @ModelAttribute Account account,
                                 BindingResult result)
{
    this.logger.info("Registering account: {}", account);

    if (result.hasErrors()) {
        return "customer/register";
    }
    this.accountService.save(account);
    return "redirect:/customer/account/" + account.getId();
}

Add this to your controller: 

@InitBinder
public void initBinder(final WebDataBinder binder){
  final SimpleDateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy"); 
  binder.registerCustomEditor(Date.class, new CustomDateEditor(dateFormat, true));
}
