java快速导出excel文件

① java中导出到Excel

java中jxl导出数据到excel的例子
import jxl.*;
import jxl.write.*;
import java.io.*;
import java.io.File.*;
import java.util.*;

public class excel
{
public static void main(String[] args)
{

String targetfile = "c:/out.xls";//输出的excel文件名
String worksheet = "List";//输出的excel文件工作表名
String[] title = {"ID","NAME","DESCRIB"};//excel工作表的标题

WritableWorkbook workbook;
try
{
//创建可写入的Excel工作薄,运行生成的文件在tomcat/bin下
//workbook = Workbook.createWorkbook(new File("output.xls"));
System.out.println("begin");

OutputStream os=new FileOutputStream(targetfile);
workbook=Workbook.createWorkbook(os);

WritableSheet sheet = workbook.createSheet(worksheet, 0); //添加第一个工作表
//WritableSheet sheet1 = workbook.createSheet("MySheet1", 1); //可添加第二个工作
/*
jxl.write.Label label = new jxl.write.Label(0, 2, "A label record"); //put a label in cell A3, Label(column,row)
sheet.addCell(label);
*/

jxl.write.Label label;
for (int i=0; i<title.length; i++)
{
//Label(列号,行号 ,内容 )
label = new jxl.write.Label(i, 0, title[i]); //put the title in row1
sheet.addCell(label);
}

//下列添加的对字体等的设置均调试通过，可作参考用

//添加数字
jxl.write.Number number = new jxl.write.Number(3, 4, 3.14159); //put the number 3.14159 in cell D5
sheet.addCell(number);

//添加带有字型Formatting的对象
jxl.write.WritableFont wf = new jxl.write.WritableFont(WritableFont.TIMES,10,WritableFont.BOLD,true);
jxl.write.WritableCellFormat wcfF = new jxl.write.WritableCellFormat(wf);
jxl.write.Label labelCF = new jxl.write.Label(4,4,"文本",wcfF);
sheet.addCell(labelCF);

//添加带有字体颜色,带背景颜色 Formatting的对象
jxl.write.WritableFont wfc = new jxl.write.WritableFont(WritableFont.ARIAL,10,WritableFont.BOLD,false,jxl.format.UnderlineStyle.NO_UNDERLINE,jxl.format.Colour.RED);
jxl.write.WritableCellFormat wcfFC = new jxl.write.WritableCellFormat(wfc);
wcfFC.setBackground(jxl.format.Colour.BLUE);
jxl.write.Label labelCFC = new jxl.write.Label(1,5,"带颜色",wcfFC);
sheet.addCell(labelCFC);

//添加带有formatting的Number对象
jxl.write.NumberFormat nf = new jxl.write.NumberFormat("#.##");

jxl.write.Number labelNF = new jxl.write.Number(1,1,3.1415926,wcfN);
sheet.addCell(labelNF);

//3.添加Boolean对象
jxl.write.Boolean labelB = new jxl.write.Boolean(0,2,false);
sheet.addCell(labelB);

//4.添加DateTime对象
jxl.write.DateTime labelDT = new jxl.write.DateTime(0,3,new java.util.Date());
sheet.addCell(labelDT);

//添加带有formatting的DateFormat对象
jxl.write.DateFormat df = new jxl.write.DateFormat("ddMMyyyyhh:mm:ss");
jxl.write.WritableCellFormat wcfDF = new jxl.write.WritableCellFormat(df);
jxl.write.DateTime labelDTF = new jxl.write.DateTime(1,3,new java.util.Date(),wcfDF);
sheet.addCell(labelDTF);

//和宾单元格
//sheet.mergeCells(int col1,int row1,int col2,int row2);//左上角到右下角
sheet.mergeCells(4,5,8,10);//左上角到右下角
wfc = new jxl.write.WritableFont(WritableFont.ARIAL,40,WritableFont.BOLD,false,jxl.format.UnderlineStyle.NO_UNDERLINE,jxl.format.Colour.GREEN);
jxl.write.WritableCellFormat wchB = new jxl.write.WritableCellFormat(wfc);
wchB.setAlignment(jxl.format.Alignment.CENTRE);
labelCFC = new jxl.write.Label(4,5,"单元合并",wchB);
sheet.addCell(labelCFC); //

//设置边框
jxl.write.WritableCellFormat wcsB = new jxl.write.WritableCellFormat();
wcsB.setBorder(jxl.format.Border.ALL,jxl.format.BorderLineStyle.THICK);
labelCFC = new jxl.write.Label(0,6,"边框设置",wcsB);
sheet.addCell(labelCFC);
workbook.write();
workbook.close();
}catch(Exception e)
{
e.printStackTrace();
}
System.out.println("end");
Runtime r=Runtime.getRuntime();
Process p=null;
//String cmd[]={"notepad","exec.java"};
String cmd[]={"C:\\Program Files\\Microsoft Office\\Office\\EXCEL.EXE","out.xls"};
try{
p=r.exec(cmd);
}
catch(Exception e){
System.out.println("error executing: "+cmd[0]);
}

}
}

② java怎样输出excel文件

//java生成简单的Excel文件
packagebeans.excel;
importjava.io.IOException;
importjava.io.OutputStream;
importjxl.Workbook;
importjxl.write.Label;
importjxl.write.WritableSheet;
importjxl.write.WritableWorkbook;
importjxl.write.WriteException;

publicclassSimpleExcelWrite{
publicvoidcreateExcel(OutputStreamos)throwsWriteException,IOException{
//创建工作薄
WritableWorkbookworkbook=Workbook.createWorkbook(os);
//创建新的一页
WritableSheetsheet=workbook.createSheet("FirstSheet",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
Labelxuexiao=newLabel(0,0,"学校");
sheet.addCell(xuexiao);
Labelzhuanye=newLabel(1,0,"专业");
sheet.addCell(zhuanye);
Labeljingzhengli=newLabel(2,0,"专业竞争力");
sheet.addCell(jingzhengli);

Labelqinghua=newLabel(0,1,"清华大学");
sheet.addCell(qinghua);
Labeljisuanji=newLabel(1,1,"计算机专业");
sheet.addCell(jisuanji);
Labelgao=newLabel(2,1,"高");
sheet.addCell(gao);

Labelbeida=newLabel(0,2,"北京大学");
sheet.addCell(beida);
Labelfalv=newLabel(1,2,"法律专业");
sheet.addCell(falv);
Labelzhong=newLabel(2,2,"中");
sheet.addCell(zhong);

Labelligong=newLabel(0,3,"北京理工大学");
sheet.addCell(ligong);
Labelhangkong=newLabel(1,3,"航空专业");
sheet.addCell(hangkong);
Labeldi=newLabel(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();
}

}

③ java怎么导出excel表格

通过这个例子，演示以下如何用java生成excel文件：
import org.apache.poi.hssf.usermodel.*;
import java.io.FileOutputStream;
import java.io.IOException;
publicclass CreateCells
{
publicstaticvoid main(String[] args)
throws IOException
{
HSSFWorkbook wb = new HSSFWorkbook();//建立新HSSFWorkbook对象
HSSFSheet sheet = wb.createSheet("new sheet");//建立新的sheet对象
// Create a row and put some cells in it. Rows are 0 based.
HSSFRow row = sheet.createRow((short)0);//建立新行
// Create a cell and put a value in it.
HSSFCell cell = row.createCell((short)0);//建立新cell
cell.setCellValue(1);//设置cell的整数类型的值
// Or do it on one line.
row.createCell((short)1).setCellValue(1.2);//设置cell浮点类型的值
row.createCell((short)2).setCellValue("test");//设置cell字符类型的值
row.createCell((short)3).setCellValue(true);//设置cell布尔类型的值
HSSFCellStyle cellStyle = wb.createCellStyle();//建立新的cell样式
cellStyle.setDataFormat(HSSFDataFormat.getFormat("m/d/yy h:mm"));//设置cell样式为定制的日期格式
HSSFCell dCell =row.createCell((short)4);
dCell.setCellValue(new Date());//设置cell为日期类型的值
dCell.setCellStyle(cellStyle); //设置该cell日期的显示格式
HSSFCell csCell =row.createCell((short)5);
csCell.setEncoding(HSSFCell.ENCODING_UTF_16);//设置cell编码解决中文高位字节截断
csCell.setCellValue("中文测试_Chinese Words Test");//设置中西文结合字符串
row.createCell((short)6).setCellType(HSSFCell.CELL_TYPE_ERROR);//建立错误cell
// Write the output to a file
FileOutputStream fileOut = new FileOutputStream("workbook.xls");
wb.write(fileOut);
fileOut.close();
}
}

④ java怎么实现导出excel

import java.io.FileOutputStream;

}

public static void main(String[] args) throws Exception
{
// 第一步，创建一个webbook，对应一个Excel文件
HSSFWorkbook wb = new HSSFWorkbook();
// 第二步，在webbook中添加一个sheet,对应Excel文件中的sheet
HSSFSheet sheet = wb.createSheet("学生表一");
// 第三步，在sheet中添加表头第0行,注意老版本poi对Excel的行数列数有限制short

// 第五步，写入实体数据 实际应用中这些数据从数据库得到，
List list = CreateSimpleExcelToDisk.getStudent();

for (int i = 0; i < list.size(); i++)
{
row = sheet.createRow((int) i + 1);
Student stu = (Student) list.get(i);
// 第四步，创建单元格，并设置值
row.createCell((short) 0).setCellValue((double) stu.getId());

cell.setCellValue(new SimpleDateFormat("yyyy-mm-dd").format(stu
.getBirth()));
}
// 第六步，将文件存到指定位置
try

FileOutputStream fout = new FileOutputStream("E:/students.xls");
wb.write(fout);
fout.close();
}
catch (Exception e)
{
e.printStackTrace();

需要的jar包：jxl.jar

⑦ java导出excel

wb = Workbook.getWorkbook(file);//按路径获取抄excel表
Sheet sheet = wb.getSheet(0);//第一个工作簿
sheet.getCell(x,y).getContents())//获取x列y行的数据；
需要一个jxl架包

⑧ java如何另存导出Excel

1./**

* 出险信息导出到excel（fc）

* @param mapping

* @param form

* @param request

* @param response

* @throws IOException

*/

public void exportActoExcel(ActionMapping mapping, ActionForm form ,

HttpServletRequest request,HttpServletResponse response) throws IOException {

ActionErrors errors = new ActionErrors();

AcExcelBusi acBusi = new AcExcelBusi();

AccidentRecordForm arForm= (AccidentRecordForm) form;

AccidentRecordBusi arBusi = new AccidentRecordBusi();

// ////查询条件

FwUsers sessUser = (FwUsers)request.getSession().getAttribute(ConstValues.SESS_USER_MANAGE);

Map<String,Object> cisMap = arBusi.getTodoPageList(arForm,sessUser,errors);

List AcList = null;// 当页的记录

if (null != cisMap) {

AcList = (List) cisMap.get("list");

}

//导出excel的路径、文件名

String uuid = UUID.create("exp");

String path = request.getSession().getServletContext().getRealPath("/") + ConstValues.EXP_PATH_EXCEL + uuid + ".xls";

acBusi.exprotAcExcel(AcList, path,request);

response.sendRedirect("stdownload.jsp?path=" + path );

}

⑨ 如何用java完成Excel快速的导入导出

导出
现在我们定义好对象了,如何导出Excel --ExcelExportUtil 这个导出工具类
public void testExportExcel_1() throws Exception {
ExportParams params = new ExportParams("0328课程表", "日期：2016-03-28", "六年一班");
Workbook workbook = ExcelExportUtil.exportExcel(params, CourseEntity.class,courseList);
FileOutputStream fos = new FileOutputStream("D:/excel/0328课程表.xls");
workbook.write(fos);
fos.close();
}
我们只要把我们定义好的对象的class传进去,以及对象的集合,Easypoi就可以返回一个Excel的workbook了,同时Easypoi是兼容03版本office和07版本office,你要穿个参数指定下类型及可以了,是不是不是比我们自己写代码简单多了,最少只需要2行代码就可以完成我们的office操作了

导入
我们把导出写完了,导入是不是很复杂呢,也不是,导入也是同样简单,定时实体和上面定义的方式一样
导入是用导入工具类
ImportParams params = new ImportParams();
params.setHeadRows(2);
List<CourseEntity> list = ExcelImportUtil.importExcel(inputStream, CourseEntity.class, params);

定义下表头的参数,然后把流传入进去就可以得到我们的对象列表是不是so easy.赶快来使用吧

⑩ 如何导出生成excel文件 java

在编程中经常需要使用到表格（报表）的处理主要以Excel表格为主。下面给出用java写入数据到excel表格方法：
1.添加jar文件
