Java读取execl数据

1.先创建execl：sample.xls

2.Java部分：先下载导入poi-*.jar架包。楼主使用的是poi-3.9.jar　　

package test;

import java.io.FileInputStream;

import org.apache.poi.hssf.usermodel.HSSFSheet;
import org.apache.poi.hssf.usermodel.HSSFWorkbook;
import org.apache.poi.ss.usermodel.Cell;
import org.apache.poi.ss.usermodel.Row;

public class ExeclDemo {
    public static void main(String[] args) {
        ExeclDemo execlDemo = new ExeclDemo();
        try {
            execlDemo.sheet1();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    public void sheet1(){
        String filePath = "C:/Users/it_zhaojie/Desktop/sample.xls";
        FileInputStream stream;
        try {
            stream = new FileInputStream(filePath);
            HSSFWorkbook workbook = new HSSFWorkbook(stream);// 读取现有的Excel
            HSSFSheet sheet = workbook.getSheet("Sheet1");// 得到指定名称的Sheet
            for (Row row : sheet) {
                for (Cell cell : row) {
                    System.out.print(cell + "	");
                }
                System.out.println();
            }
        } catch (Exception e) {
            e.printStackTrace();
        }

    }

}

2.1不读取第一行只读取内容

    public void sheet2(){
        String filePath = "C:/Users/it_zhaojie/Desktop/sample.xls";
        FileInputStream stream;
        try {
            stream = new FileInputStream(filePath);
            HSSFWorkbook workbook = new HSSFWorkbook(stream);// 读取现有的Excel
            HSSFSheet sheet = workbook.getSheet("Sheet1");// 得到指定名称的Sheet
            List<Row> list = new ArrayList<Row>();
            for (Row row : sheet) {
                list.add(row);
            }
            
            for (int i = 1; i < list.size(); i++) {
                for (Cell cell : list.get(i)) {
                    System.out.print(cell + "	");
                }
                System.out.println();
            }
        } catch (Exception e) {
            e.printStackTrace();
        }

    }

3.运行效果
