Hibernate Search 和 Lucene：无法确定排序类型

发布于 2024-07-26 14:49:35 字数 3123 浏览 1 评论 0原文

我正在使用 Hibernate - Lucene 搜索。

当索引文件/表中没有可用数据时，我在排序时出现以下运行时异常。

这是我的代码：

......... ………… 查询.setFirstResult(startIndex); query.setMaxResults(displayCount);

                 Sort sort = null;
            SortField sortField = new SortField**("vendorName",!true);
            sort = new Sort(sortField);
            query.setSort(sort);

            objList = query.setProjection(searchFields).setResultTransformer(objSavantAliasToBeanResultTransformer).list();

………… ........

I am using Hibernate - Lucene Search.

I have the following Runtime Exception while sorting when no data available in index file/table.

This is my code:

..........
..........
query.setFirstResult(startIndex);
query.setMaxResults(displayCount);

                 Sort sort = null;
            SortField sortField = new SortField**("vendorName",!true);
            sort = new Sort(sortField);
            query.setSort(sort);

            objList = query.setProjection(searchFields).setResultTransformer(objSavantAliasToBeanResultTransformer).list();
