JAVA用POI读取EXCEL的例子 超简单

import org.apache.poi.hssf.usermodel.HSSFWorkbook;

import org.apache.poi.hssf.usermodel.HSSFSheet;

import org.apache.poi.hssf.usermodel.HSSFCell;

import java.io.FileInputStream;

public class ReadXL {

/** Excel文件的存放位置。注意是正斜线 */

public static String fileToBeRead = "E:/201012排班.xls";

public static void main(String argv[]) {

try {

// 创建对Excel工作簿文件的引用

HSSFWorkbook workbook = new HSSFWorkbook(new FileInputStream(

fileToBeRead));

// 创建对工作表的引用。

// 也可用getSheetAt(int index)按索引引用，

// 在Excel文档中，第一张工作表的缺省索引是0，

// 其语句为：HSSFSheet sheet = workbook.getSheetAt(0);

// 读取左上端单元

System.out.println("sheet数目： " + workbook.getNumberOfSheets());

for (int i = 0; i < workbook.getNumberOfSheets(); i++) {// 循环sheet

System.out

.println("==========开始第 " + i + " 个sheet============");

HSSFSheet childSheet = workbook.getSheetAt(i);

for (int r = 0; r < childSheet.getPhysicalNumberOfRows(); r++) {// 循环该

// 子sheet

// row

System.out.println("childSheet " + (r + 1) + "行数:: "

+ childSheet.getPhysicalNumberOfRows());

System.out.println("childSheet 单元格的数目:: "

+ childSheet.getRow(r).getPhysicalNumberOfCells());

for (int c = 0; c < childSheet.getRow(r)

.getPhysicalNumberOfCells(); c++) {// 循环该子sheet行对应的单元格项

HSSFCell cell = childSheet.getRow(r).getCell(c);

System.out.println("cell:: " + cell);

String value = null;

if (cell == null)

continue;

System.out.println("cell.getCellType():: "

+ cell.getCellType());

switch (cell.getCellType()) {

case HSSFCell.CELL_TYPE_NUMERIC:

value = "" + cell.getNumericCellValue();

break;

case HSSFCell.CELL_TYPE_STRING:

value = cell.getStringCellValue();

break;

case HSSFCell.CELL_TYPE_BLANK:

;

break;

default:

}

System.out.println("value :: " + value);

}

}

}

// HSSFRow row = sheet.getRow(0);//行

// HSSFCell cell = row.getCell((short) 0);//单元格

// 输出单元内容，cell.getStringCellValue() 就是取所在单元的值

} catch (Exception e) {

System.out.println("已运行xlRead() : " + e);

}

}

}
