beforeDoOperation方法获取操作状态（保存、提交）

@Override

            String operateKey = button.getOperateKey();
            if (HRStringUtils.equals(operateKey, HRBaseConstants.SAVE)) {
                // todo 为了测试, 之后再审核完后调用
                ApplyHelper.setCerInfo(this.getModel().getDataEntity());
                this.getModel().getDataEntity().set(ApplyConstants.FIELD_CERSTATUS, CerStatusEnum.SUBMIT_NO.getNumber());
                // 构造活动处理人
                constructHandler();
