Question

Plain and simple issue:

• I would like to annotate my method parameter with some sort of annotation that would fire regular spring validation mechanism (based on Validator interface)
• I don’t want to include JSR303 dependency

Any ideas? I looked on @Validated but it seems that it was not created for this purpose.

Right now I do it like this:

public String req(@ModelAttribute SomeRequest request, BindingResult errors) {
        validator.validate(request, errors); // This can be avoided
        if (!errors.hasErrors()) {
            // Valid request
            return ...
        } else {
            // There were errors 
            return ...
        }
}

In that case you need to create custom annotation using @interface and then use that instead of standard @Valid annotation and at runtime identify it and validate your fields accordingly. Hope this helps you. Cheers.
