Java解析Excel内容的方法

本文实例讲述了Java解析Excel内容的方法。分享给大家供大家参考。具体实现方法如下：

代码如下:

import java.io.File; 
import java.io.FileInputStream; 
import java.io.InputStream; 
import java.util.ArrayList; 
import org.apache.poi.hssf.usermodel.HSSFWorkbook; 
import org.apache.poi.ss.usermodel.Cell; 
import org.apache.poi.ss.usermodel.Row; 
import org.apache.poi.ss.usermodel.Sheet; 
import org.apache.poi.ss.usermodel.Workbook; 
import org.apache.poi.xssf.usermodel.XSSFWorkbook; 
public class Test { 
    /**
     * @param args
     */ 
    public static void main(String[] args) { 
        meetquery("403", "e:\\Excel\\1火灾三级预案处置流程.xlsx"); 
    } 
    private static ArrayList<MeetBean> meetquery(String level, String filename) { 
        ArrayList<MeetBean> list = new ArrayList<MeetBean>(); 
        try { 
            File file = new File(filename); 
            InputStream is = new FileInputStream(file); 
            Workbook workbook = null;// 一个workbook对象，就是一个Excel文件 
            Sheet sheet = null;// sheet页，因excel总有多个sheet页，需要判断具体取值哪一个 
            Row row1 = null;// Sheet页数中的某一行 
            int colNum = 0;// Sheet总行数 
            Cell cell = null;// 第一列内容 
            Cell cell1 = null;// 第二列内容 
            String meetname = null;// 要点名称 
            String meetid = null;// 要点编号

            if (filename.endsWith(".xls")) { 
                workbook = new HSSFWorkbook(is);// Excel 2003 
            } else if (filename.endsWith(".xlsx")) {

            } else { 
                return null; 
            }
