[FIXED] Get values and fields from BindingResult

Issue

I have method which have BindingResult.

@PostMapping("/spare-create")
    public String saveSpare(@Valid Spares spares, BindingResult bindingResult, RedirectAttributes attributes) {
        if (bindingResult.hasErrors()) {
            attributes.addAttribute("orderNumberError", spares.getOrderNumber());
            attributes.addAttribute("orderMarkError", spares.getOrderMark());           
            List<ObjectError> errors = bindingResult.getAllErrors();
            errors.forEach(element -> System.out.print(errors + ""));
            
            return "redirect:/ab2";
        } else {
            sparesServiceImpl.saveSpares(spares);
            return "redirect:/new-docs";
        }
    }

I tried to get all errors, but get output like

[Field error in object 'spares' on field 'orderNumber': rejected value [12345]; codes [Size.spares.orderNumber,Size.orderNumber,Size.java.lang.String,Size]; arguments [org.springframework.context.support.DefaultMessageSourceResolvable: codes [spares.orderNumber,orderNumber]; arguments []; default message [orderNumber],2147483647,6]; default message [размер должен находиться в диапазоне от 6 до 2147483647]]

How can I get data in format like: "Field and value"?

Solution

As long as you're interested only in field errors you can call getFieldErrors() method on BindingResult instead of getAllErrors(), which will return collection of FieldErrors instead of ObjectErrors.

FieldError provides access to field name and rejected value, so you can achieve your goal like that:

bindingResult.getFieldErrors()
                .forEach(e -> System.out.println(
                        "field: " + e.getField() + ", rejected value: " + e.getRejectedValue()));
