importorg.apache.poi.hssf.usermodel.HSSFWorkbook;

publicclassTest {

publicstaticvoidmain(String[] args) {

try{

HSSFWorkbook workbook = newHSSFWorkbook();

FileOutputStream fileOut = newFileOutputStream("D:/2.xls");

workbook.write(fileOut);

fileOut.close();

} catch(IOException e) {

e.printStackTrace();

}

}

}

java如何生成excel具体的

poi或jxl都行

你从网上下载个jxl.jar的jar包

简单说一下jxl导出excel过程

//先创建一个excel文件

String excelPath = "D:\\系统用户.xls";

File excelFile = new File(excelPath);

if (!excelFile.exists()) {

excelFile.createNewFile();

}

WritableWorkbook book = Workbook.createWorkbook(excelFile);

WritableSheet ws = book.createSheet("用户信息", 0); //新建一个sheet

---------------

//往表中添加内容

ws.addCell(WritableCell )

------------

//将数据写入所建的excel

book.write();

book.close();

java怎样输出excel文件

//java生成简单的Excel文件

package beans.excel;

import java.io.IOException;

import java.io.OutputStream;

import jxl.Workbook;

import jxl.write.Label;

import jxl.write.WritableSheet;

import jxl.write.WritableWorkbook;

import jxl.write.WriteException;

public class SimpleExcelWrite {

public void createExcel(OutputStream os) throws WriteException,IOException{

//创建工作薄

WritableWorkbook workbook = Workbook.createWorkbook(os);

//创建新的一页

WritableSheet sheet = workbook.createSheet("First Sheet",0);

//创建要显示的内容,创建一个单元格,第一个参数为列坐标,第二个参数为行坐标,第三个参数为内容

Label xuexiao = new Label(0,0,"学校");

sheet.addCell(xuexiao);

Label zhuanye = new Label(1,0,"专业");

sheet.addCell(zhuanye);

Label jingzhengli = new Label(2,0,"专业竞争力");

sheet.addCell(jingzhengli);

Label qinghua = new Label(0,1,"清华大学");

sheet.addCell(qinghua);

Label jisuanji = new Label(1,1,"计算机专业");

sheet.addCell(jisuanji);

Label gao = new Label(2,1,"高");

sheet.addCell(gao);

Label beida = new Label(0,2,"北京大学");

sheet.addCell(beida);

Label falv = new Label(1,2,"法律专业");

sheet.addCell(falv);

Label zhong = new Label(2,2,"中");

sheet.addCell(zhong);

Label ligong = new Label(0,3,"北京理工大学");

sheet.addCell(ligong);

Label hangkong = new Label(1,3,"航空专业");

sheet.addCell(hangkong);

Label di = new Label(2,3,"低");

sheet.addCell(di);

//把创建的内容写入到输出流中,并关闭输出流

workbook.write();

workbook.close();

os.close();

}

}
