一、HSSF  97-2003

      需要jar:poi-3.9.jar

      简单示例：生成EXCEL

            //93---2003

            String [] titlie={"id","name","sex"};

            //创建Excel工作簿

            HSSFWorkbook  workBook=new HSSFWorkbook();

            //创建一个Sheet页

            HSSFSheet  sheet=workBook.createSheet();

            //创建第一行

            HSSFRow  row=sheet.createRow(0);

            //定义单元格

            HSSFCell  cell=null;

            //插入第一行数据id，name,sex

            for (int i = 0; i < titlie.length; i++) {

                cell=row.createCell(i);

                cell.setCellValue(titlie[i]);

            }

            //追加数据

            for(int i=1;i<10;i++){

                HSSFRow   nextrow=sheet.createRow(i);

                HSSFCell  cell2=nextrow.createCell(0);

                cell2.setCellValue("a"+i);

                cell2=nextrow.createCell(1);

                cell2.setCellValue("user"+i);

                cell2=nextrow.createCell(2);

                cell2.setCellValue("男");

            }

            //创建一个文件

            File  file=new File("C:/Users/Administrator/Desktop/POI_test.xls");

            try {

                file.createNewFile();

                FileOutputStream stream=FileUtils.openOutputStream(file);

                workBook.write(stream);

                stream.close();

                System.out.println(">>>结束");

            } catch (IOException e) {

                e.printStackTrace();

            }

解析EXCEL

        //93---2003

        //引入需要解析的Excel文件

        File  file=new File("C:/Users/Administrator/Desktop/POI_test.xls");

        try {

            //创建Excel,读取文件内容

            HSSFWorkbook   workbook=

                    new HSSFWorkbook(FileUtils.openInputStream(file));

        //HSSFSheet  sheet=workbook.getSheet("");//名称或者（获取第一个工作表）

        HSSFSheet sheet=workbook.getSheetAt(0);

        int firstRowNum=0;

        //获取sheet中最后银行行号

        int lastRowNum=sheet.getLastRowNum();

        for (int i = firstRowNum; i < lastRowNum; i++) {

            HSSFRow  row=sheet.getRow(i);

            //获取当前行最后单元格列号

            int lastCellNum=row.getLastCellNum();

            for(int j=0;j<lastCellNum;j++){

                HSSFCell  cell=row.getCell(j);

                String value=cell.getStringCellValue();

                System.err.print(value+"  >>");

            }

            System.err.println();

        }

        } catch (IOException e) {

            // TODO Auto-generated catch block

            e.printStackTrace();

        }

2007------生成EXCEL

需要JAR:

    //2007

            String [] titlie={"id","name","sex"};

            //创建Excel工作簿

            XSSFWorkbook  workBook=new XSSFWorkbook();

            //创建一个Sheet页

            Sheet  sheet=workBook.createSheet();

            //创建第一行

            Row  row=sheet.createRow(0);

            //定义单元格

            Cell  cell=null;

            //插入第一行数据id，name,sex

            for (int i = 0; i < titlie.length; i++) {

                cell=row.createCell(i);

                cell.setCellValue(titlie[i]);

            }

            //追加数据

            for(int i=1;i<10;i++){

                Row   nextrow=sheet.createRow(i);

                Cell  cell2=nextrow.createCell(0);

                cell2.setCellValue("a"+i);

                cell2=nextrow.createCell(1);

                cell2.setCellValue("user"+i);

                cell2=nextrow.createCell(2);

                cell2.setCellValue("男");

            }

            //创建一个文件

            File  file=new File("C:/Users/Administrator/Desktop/POI_test07Last.xlsx");

            try {

                file.createNewFile();

                FileOutputStream stream=FileUtils.openOutputStream(file);

                workBook.write(stream);

                stream.close();

                System.out.println(">>>结束");

            } catch (IOException e) {

                e.printStackTrace();

            }
