工程目录结构以及所需的jar包如下:

工具:poi-2.0-RC2-20040102.jar(注意:这里并没有使用本机自带的Excel2007制作模板)
现在很多工具都要版本对应才能使用,eg:在使用poi-2.0-RC2时 必须使用老版本的Excel新建xls文件,Excel2007
新建的Excel是".xlsx"结尾的,不能使用poi-2.0-RC2。
又比如:在使用itext1.3时,使用现在普遍存在的adobe acrobat7.0以上的版本制作的模板都不行,但使用itext2.0就可以解决中文无法显示(或乱码的问题)
如果你电脑上安装的是Excel2007的话,可能就比较麻烦啦!当然也不是必须使用Excel来建立模板
我们可以这样做:使用poi自身来建立一个.xls文件,这个文件肯定是符合poi版本的
1.fos = new FileOutputStream(file); 直接建立一个xls文档
2.用如下方式
package com.excel;
import org.apache.poi.hssf.usermodel.HSSFWorkbook;
import org.apache.poi.hssf.usermodel.HSSFSheet;
import org.apache.poi.hssf.usermodel.HSSFRow;
import org.apache.poi.hssf.usermodel.HSSFCell;
import java.io.FileOutputStream;
/**
* 利用POI API创建Excel文档
* @author fshitd88

*/
public class CreateXL {
/** Excel 文件要存放的位置,假定在D盘下。
* 现在D盘下还没有excel文件,通过下面成程序可以创建Excel文件
* */
public static String outputFile = "D:\\test.xls";
public static void main(String argv[]) {
try {
// 创建新的Excel 工作簿
HSSFWorkbook workbook = new HSSFWorkbook();
// 在Excel工作簿中建一工作表,其名为缺省值
// 如要新建一名为"效益指标"的工作表,其语句为:
// HSSFSheet sheet = workbook.createSheet("效益指标");
HSSFSheet sheet = workbook.createSheet();
// 在索引0的位置创建行(最顶端的行)
HSSFRow row = sheet.createRow((short) 0);
// 在索引0的位置创建单元格(左上端)
HSSFCell cell = row.createCell((short) 0);
// 定义单元格为字符串类型
cell.setCellType(HSSFCell.CELL_TYPE_STRING);
cell.setCellValue("高红成");//写入中文有问题
//解决中文件乱码
HSSFCell cell1 = row.createCell((short) 1);
cell1.setEncoding((short) 1);//解决中文乱码问题
// 在单元格中输入一些内容
cell1.setCellValue("高伟刚");//写入中文有问题
// 新建一输出文件流
FileOutputStream fOut = new FileOutputStream(outputFile);
// 把相应的Excel 工作簿存盘
workbook.write(fOut);
fOut.flush();
// 操作结束,关闭文件
fOut.close();
System.out.println("文件生成...");
} catch (Exception e) {
System.out.println("已运行 xlCreate() : " + e);
}
}
}修改Excel文件第一行,就形成了一个简单的模板了
