it helps some times I´m trying to create a form and validate its data via @Valid on the command object. The validation performs well, but an error is ocurring going back to web. , This
code :
public String register(final ModelMap model,
        @Valid final UsuarioForm userForm,
        final BindingResult result)
public String register(final ModelMap model,
        @ModelAttribute("userForm") @Valid final UsuarioForm userForm,
        final BindingResult result)

With these it helps You need a validation.properties file at /WEB-INF/messages with an entry similar to this (for example):
code :
NotEmpty.homeFormItem.one=The field {0} is empty
<bean id="messageSource" class="org.springframework.context.support.ReloadableResourceBundleMessageSource">
    <property name="basename" value="/WEB-INF/messages/validation" />
</bean>

help you fix your problem I think you may be having the same issue as I did - please see :
Fields object functions (Spring)
code :
public String post(@Valid FormData formData, BindingResult result, Model model){
    // th:object="${formData}"
}
public String post(@Valid @ModelAttribute("data") FormData data, BindingResult result, Model model){
    // th:object="${data}"
}

Does that help I believe that the BindingResult needs to directly follow the Valid annotation'd parameter in the parameter list.
See Why does BindingResult have to follow @Valid?

will help you You're not adding the model in the controller, to match the th:Object in the form. In your ReserveHandler you need to add the model attribute. I'm not sure how things have changed (if at all) recently, but I've done this before (using some of your model names in this case):
code :
public String myGetRequest(Model model) {
    if (!model.containsAttribute("Booking")) {
        // Add the named model attribute here
        model.addAttribute("Booking", new Booking());
    }
    return "booking/reserve";
}

@PostMapping(...)
public String myPostRequest(
    @Valid @ModelAttribute Booking booking,
    final BindingResult bindingResult,
    final RedirectAttributes redirectAttributes
) {
    if (bindingResult.hasErrors()) {
        // Adds the validation errors
        redirectAttributes.addFlashAttribute("org.springframework.validation.BindingResult.Booking", bindingResult);

        // Set the model attribute
        redirectAttributes.addFlashAttribute("Booking", booking);
        return "redirect:/booking/reserve";
    }
    // Otherwise...
    return "redirect:/booking/show";
}

With these it helps First of all your current message is not due to the date being in the future but due to the date format is wrong and the date cannot be parsed.
Other than that you can customize error messages like this: https://stackoverflow.com/a/5781678/878361
