我想向数据库插入一条记录，所以这是我的控制器：

@RequestMapping(value="/ajouter_activite",method = RequestMethod.POST)
    public String AddActivity(@ModelAttribute Movement movement, ModelMap model,BindingResult result){
        AddActivityValidator actvalidator = new AddActivityValidator();
        actvalidator.validate(movement, result);
        if(!result.hasErrors()){
        boolean n;
        n=actservice.addMovement(movement);
        if(n==true){model.addAttribute("success","true");}
        else {model.addAttribute("echec","true");}
        return "/FicheService";}
        else{return "/FicheService";
        }

    }

当我发送我的表格时，我得到了这个例外：

Etat HTTP 500 - Request processing failed; nested exception is org.springframework.web.bind.annotation.support.HandlerMethodInvocationException: Failed to invoke handler method [public java.lang.String gestion.delegation.controller.FicheServiceController.AddActivity(gestion.delegation.domaine.Movement,org.springframework.ui.ModelMap,org.springframework.validation.BindingResult)]; nested exception is java.lang.IllegalStateException: Errors/BindingResult argument declared without preceding model attribute. Check your handler method signature!

那哪里错了？

尝试 

public String AddActivity(@ModelAttribute Movement movement, BindingResult result, ModelMap model)

方法签名。
