@Validated annotation not working

Question

I'm trying to use the @Validated annotation to valid form data returned to a controller, but it fails to call the custom validator that I have created. Code below:

@PostMapping("/saveTransaction")
    public String saveTransaction(@ModelAttribute("transaction") 
@Validated Transactions transaction, BindingResult bindingResult) {

    if(bindingResult.hasErrors()) {
        System.out.println("Non formated form stuff.");
        return "transactions/transactionsForm";
    }

The code works if I manual call the Validator as in:

@PostMapping("/saveTransaction")
    public String saveTransaction(@ModelAttribute("transaction") Transactions transaction, BindingResult bindingResult) {
        validator.validate(transaction, bindingResult);
        if(bindingResult.hasErrors()) {
            System.out.println("Non formated form stuff.");
            return "transactions/transactionsForm";
        }

I am auto wiring my class and initializing the validator using the following code.

    @Autowired
    private TransactionService transactionService;

    @Autowired
    @Qualifier("transactionValidator")
    private Validator validator;

    @InitBinder
    private void initBinder(WebDataBinder binder) {
        binder.setValidator(validator);
    }

I have the following code in Spring.xml file:

    <mvc:annotation-driven validator="transactionValidator" />

    <bean id="transactionValidator" class="org.lexusmanson.lexbudget.validator.TransactionValidator" />

Why won't the annotation call my validation code?

Answer 1

Can you try with @valid annotation instead of @validated hope it will help.

Answer 2

Change the code as mentioned below: Binding result should come after @Valid annotation

@PostMapping("/saveTransaction")
    public String saveTransaction(@Valid Transactions transaction, BindingResult bindingResult) {
        validator.validate(transaction, bindingResult);
        if(bindingResult.hasErrors()) {
            System.out.println("Non formated form stuff.");
            return "transactions/transactionsForm";
        }
