使用POI-HSSF读取excel文件

POI官方网址：http://poi.apache.org/
POI是Apache一个开源项目,主要解决使用java阅读和创建MS系列的Word,Excel,PowerPoint,Visio等文档
这里只附上使用POI读取Excel文件的一个小例子，如果需要使用POI的其他功能，请浏览 http://poi.apache.org/ ，有很多例子。

本程序读取的excel文件样本


本程序使用以下jar

package com.wyh.excel.business;

import java.io.FileInputStream;
import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;

import org.apache.poi.hssf.usermodel.HSSFCell;
import org.apache.poi.hssf.usermodel.HSSFRow;
import org.apache.poi.hssf.usermodel.HSSFSheet;
import org.apache.poi.hssf.usermodel.HSSFWorkbook;
import org.apache.poi.poifs.filesystem.POIFSFileSystem;
