今天使用POI解析XLS，报错如下：

Servlet.service() for servlet [rest] in context with path [/cetBrand] threw exception [Request processing failed; nested exception is org.apache.poi.openxml4j.exceptions.InvalidOperationException: Can't open the specified file: 'd:\cet_Brand\examSorce\Sheet名不对.xls'] with root cause

报错原因是因为:

后台代码：

XSSFWorkbook workbook = new XSSFWorkbook(thisFile);
        XSSFSheet  sheet = workbook.getSheet("成绩单");

这个逻辑没有错 就是我解析的是.xls文件 而使用的是XSSFWorkbook类，应该使用

HSSFWorkbook workbook = new HSSFWorkbook(is);
        HSSFSheet sheet = workbook.getSheet("成绩单");
