感谢两位。

使用的包：

 
代码如下：

import java.util.ArrayList;
import java.io.FileInputStream;
import java.io.IOException;

            } catch (Exception ex) {
            workBook = new HSSFWorkbook(new FileInputStream(path+"\\"+fileName));
        }   

            for (int numSheet = 0; numSheet < workBook.getNumberOfSheets(); numSheet++) {
