Allow Errors/BindingResult after @RequestBody [SPR-7114] #11774
Description
Nick Padgett opened SPR-7114 and commented
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:
