Minor Description
Instead of using a command/form object, I bind much of my data to the request body. I expected that I could specify an Errors/BindingResult object after a @RequestBody method parameter. Currently, I do the following:
@RequestMapping(value = "/events", method = RequestMethod.POST) public String create(@RequestBody final Event event, final HttpServletResponse response, final Model model) throws BindException { final BindingResult result = new BeanPropertyBindingResult(event, ""); ValidationUtils.invokeValidator(this.eventValidator, event, result); if (result.hasErrors()) { throw new BindException(result); } ... }
I would like to do the following:
@RequestMapping(value = "/events", method = RequestMethod.POST) public String create(@RequestBody final Event event, final BindingResult result, final HttpServletResponse response, final Model model) throws BindException { ValidationUtils.invokeValidator(this.eventValidator, event, result); if (result.hasErrors()) { throw new BindException(result); } ... }
However, when I do, I receive the following exception:
