Adding multiple validators using initBinder

Question

I\'m adding a user validator using the initBinder method:

@InitBinder
    protected void initBinder(WebDataBinder binder) {
        binder.setVa         


        

Answer 1

You can add multiple validators by iterating over all org.springframework.validation.Validator in an ApplicationContext and set up suitable ones in @InitBinder for each request.

@InitBinder
public void setUpValidators(WebDataBinder webDataBinder) {
    for (Validator validator : validators) {
        if (validator.supports(webDataBinder.getTarget().getClass())
                && !validator.getClass().getName().contains("org.springframework"))
            webDataBinder.addValidators(validator);
    }
}

See my project for examples and simple benchmarks. https://github.com/LyashenkoGS/spring-mvc-and-jms-validation-POC/tree/benchamark

Declare request as

(... , Model model,HttpServletRequest request)

and change

model.addAttribute(customerPayment);

to

request.setAttribute("customerPayment",customerPayment);
