我在发布对Spring控制器的调用时遇到异常

例外情况是:

 org.springframework.web.bind.MissingServletRequestParameterException : Required Long parameter 'userId' is not present"

我的Javascript文件是:

$scope.removeUser = function(user){
        var userId = JSON.stringify(user);
        $http.post('/portal/settings/user/deletecustomeruser', userId).success(function(data){
                $scope.response = data;
            })
        }
    }

Spring控制器代码是:

      @RequestMapping( value = "/user/deletecustomeruser", method = RequestMethod.POST , headers="Accept=application/json")
public @ResponseBody String deleteCustomerUser( @RequestParam (value = "userId") Long userId,
        HttpServletRequest request )
                throws Exception
                {
    String returnString = "";
    User user = userService.getUserById( userId );

当我放(required = false),然后userId价值变成了null.JavaScript控制器显然"userId"是以JSON格式发送的,但是从控制器端出现了一些问题.

我在stackoverflow中检查了几乎所有问题,但给定的解决方案没有帮助.
