spring-mvc-initbinders

Hi I am a new to spring framework. I have done a small example where I tried to validate my input field using spring validation api. This is the code @RequestMapping(value = "/applicationFormSubmit", method = RequestMethod.POST) public String insertdata( @ModelAttribute("applicationForm") @Valid ApplicationFormBean applicationFormBean, @RequestParam("file") MultipartFile file, BindingResult result,Model model) { if(result.hasErrors()) { return "applicationForm"; } try { Blob blob = Hibernate.createBlob(file.getInputStream()); // applicationFormBean..setFilename(file.getOriginalFilename());

Would it be possible to have multiple initBinder Methods inside a single Controller? Where each InitBinder() (see code) depends on a unique request handler e.g. initBinder() is called on url: "/update/account" and initBinderOne() on "update/account/pass"? I would prefer to have a single Controller for all updates instead of multiple. Please advise. @Controller @RequestMapping(value="/uodate/account") public class UpdateController { @RequestMapping(method=RequestMethod.GET) public String updateAccount(@ModelAttribute("account") Account account...){ .. } @RequestMapping(method=RequestMethod.POST

I have following controller method: @RequestMapping(value = "/owner/terminals/save", method = RequestMethod.POST) public String saveTerminal( @RequestParam(value = "name") String name, @RequestParam(value = "file") @Valid OnlyForImagesFileWrapper file, BindingResult bindingResult ) { ... and I see the following stacktrace: org.springframework.beans.ConversionNotSupportedException: Failed to convert value of type 'org.springframework.web.multipart.commons.CommonsMultipartFile' to required type 'com.terminal.domain.validation.OnlyForImagesFileWrapper'; nested exception is java.lang
