AngularJS Spring mvc @RequestParam

Question

我是Angularjs的新手，以下Spring控制器通過id從數據庫獲取對象我想使用AngularJs通過@RequestParam獲取此id，我嘗試以下代碼，但收到此錯誤“錯誤：id未定義.findOne @本地主機： 8080 / myapp / scripts / services.js：126：79 $ scope.findOne @ localhost：8080 / myapp / scripts / controllers.js：280：4

Spring MVC控制器

    @RequestMapping(value = "/rest/chartConfigs/getById",
            method = RequestMethod.GET,
            produces = MediaType.APPLICATION_JSON_VALUE)
    @RolesAllowed(AuthoritiesConstants.ADMIN)
    public ChartConfigs findOne(@RequestParam(value = "id") Integer id) {
     System.out.println(chartConfigService.getOne(id));
         return chartConfigService.getOne(id);

    }

AngularJS服務

    myappApp.factory('ChartConfigService', function ($http) {
    return {
    findOne: function() {
        var promise = $http.get('app/rest/chartConfigs/getById',{params: {id: id}}).
                        then(function  (response) {
            return response.data;
        });
        return promise;
    }
  }
 });

AngularJS控制器

  myappApp.controller('ChartConfigController', function ($scope, ChartConfigService) {
    $scope.findOne= function() {
     ChartConfigService.findOne($scope.id).then(function(obj) {
            $scope.message=obj;
            console.log(obj.type);
        });
    };      
  });

您忘記將id傳遞給findOne作為函數參數：

findOne: function(id) {
        var promise = $http.get('app/rest/chartConfigs/getById',{params: {'id': id}}).
                        then(function  (response) {
            return response.data;
        });
        return promise;
    }
