Question

我试图使用$ js来获取一个对象数组的ajax调用。我传递一个路径变量，它是对象的id，当我尝试在$ resource上调用查询时，它显示下面给出了错误。资源和控制器代码如下。我在后端使用Spring MVC，下面给出了Spring代码的其余控制器。请给出一些建议，我在这里做错了什么，最佳做法是什么？这是控制台中的错误 -

这是我的服务和控制器代码 -

function getSubCategoryIdNameFn(catId){
    var deferred = $q.defer();
    $resource("admin/rest/subcategory-id-name/:catId",{catId:"@catId"}).query({catId:catId})
    .$promise
    .then(function(response){
        deferred.resolve(response);
    },function(error){
        deferred.reject(error);
    });
    return deferred.promise;
}

控制器 -

$scope.catChanged = function (){
    categoryService.getSubCategoryIdName($scope.coupon.category).then(function(response){
        $scope.subcatList = response;
    },function(error){

    });
}

我是棱角分明的新手，所以不知道控制台错误说的是什么？服务器端控制器在春天 -

@RequestMapping(value="subcategory-id-name/{catId}", method=RequestMethod.GET,produces={"application/json"})
public List<SubCategory> getSubCategoryIdAndName(@PathVariable int catId){
    return subCategoryService.getSubCategoryIdName(catId);
}

使用path参数在$ resource上调用查询时出现Angular js $ resource错误
