其余api过滤器服务，在角度6中具有多个参数

Question

我想使用多个参数作为Rest api进行搜索，并使用Angular 6进行使用

ServiceController.java

    @Spring3CorsFilter
    @ResponseBody
    @RequestMapping(value = "/searchcount", method = RequestMethod.GET,headers="Accept=application/json")
    public Integer getSearchcount(@RequestBody Orders A) {

        return this.s.getSuiviCommandeCount(A);

    }

    Service.ts

      constructor(private http: HttpClient) { }
      baseUrl = 'http://localhost:8080/FacadeController';
      private order:Orders;
      getSearchcount(order: Object): Observable<Object> {
        return this.http.get(`${this.baseUrl}` + `/searchcount`,order);
      }

我希望将过滤器参数作为对象类型Order发送
