java读取excel文件内容

1.导入依赖JAR包

<!-- jxl 操作excel -->
<dependency>
    <groupId>org.jxls</groupId>
    <artifactId>jxls-jexcel</artifactId>
    <version>1.0.6</version>
</dependency>

2.创建工作簿并载入excel文件流

jxl.Workbook wb =null;
InputStream is = new FileInputStream("D://G201.xls");
wb = Workbook.getWorkbook(is);

3.通过索引或者名称获取Sheet

wb.getSheet(0);

4.通过行号获取Cell

sheet.getRow(j)

5.示例代码展示

package com.bret.test;

import jxl.Cell;
import jxl.Sheet;
import jxl.Workbook;
import jxl.read.biff.BiffException;
import org.junit.Test;

import java.io.FileInputStream;
import java.io.IOException;
import java.io.InputStream;

public class ExcelUtil {

    @Test
    public void test(){
        try{
            jxl.Workbook wb =null;
            InputStream is = new FileInputStream("D://G201.xls");
            wb = Workbook.getWorkbook(is);

            int sheetSize = wb.getNumberOfSheets();
            Sheet sheet = wb.getSheet(0);
            int row_total = sheet.getRows();
            for (int j = 0; j < row_total; j++) {
                if(j == 0){
                    Cell[] cells = sheet.getRow(j);

                    System.out.println(cells[0].getContents());
                    System.out.println(cells[1].getContents());
                    System.out.println(cells[2].getContents());
                }
            }
        }catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (BiffException e){
            e.printStackTrace();
        }
    }

}

注意，JAVA读取exlcel仅支持.xls(97-2003工作簿)，读取后缀为.xlsx前需将文件另存为.xls。
