java - @QueryParam 无法获取请求参数

我正在尝试从 REST Web 服务的 URL 请求中获取请求参数。 @Path 能够映射方法。但 QueryParam 无法从查询参数中获取值。

我的请求网址是

        Vector oResult = (Vector) request.getAttribute("NESToutObject");

       if (oResult == null || oResult.size() == 0 || oResult.contains(NESTerror.BAD_INPUT) || oResult.contains(NESTerror.NO_DATA) || oResult.contains(NESTerror.MSG_FAILURE)) {
           } else {

       }

        return null;
}
 }

AccountId、exch 和 sym 不是查询参数，而是路径参数，因此不要使用 @QueryParam @PathParam。
