uid()不能使用了吗？
看到CmsArticleController.java 的addDo方法里面 需要手动赋值

 article.setPublishAt(time[0] / 1000);
            article.setEndAt(time[1] / 1000);
            article.setSiteid(siteid);
            article.setStatus(0);
            article.setOpBy(StringUtil.getPlatformUid());
            cmsArticleService.insert(article);
