我正在使用休眠 - Lucene 搜索。
当索引文件/表中没有可用数据时，排序时出现以下运行时异常。
这是我的代码：
.......... .......... 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();
