コントローラーで IllegalStateException が発生しています。ここに関連するのは、私のコントローラーのマッピングと署名です。
@RequestMapping(value = "/poll1", method = RequestMethod.POST)
public String processPoll1(@RequestParam String vote, Model model, BindingResult result) {
BindingResult 引数が明らかに Model 引数に従っているにもかかわらず、次のエラーが発生します。
java.lang.IllegalStateException: An Errors/BindingResult argument is expected to be immediately after the model attribute argument in the controller method signature: public java.lang.String com.controller.PollController.processPoll1(java.lang.String,org.springframework.ui.Model,org.springframework.validation.BindingResult)
