Question

我在这里看到了许多类似的问题，但是我仍然无法弄清楚为什么我的java程序出现相同的错误。

我将所有.jar文件放在类路径中，但是存在相同的错误。我的代码：

import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.Date;

import org.apache.poi.hssf.usermodel.HSSFCell;
import org.apache.poi.hssf.usermodel.HSSFCellStyle;
import org.apache.poi.hssf.usermodel.HSSFDataFormat;
import org.apache.poi.hssf.usermodel.HSSFRow;
import org.apache.poi.hssf.usermodel.HSSFSheet;
import org.apache.poi.hssf.usermodel.HSSFWorkbook;
import org.apache.poi.hssf.util.HSSFColor;

public class Export2Excel {

    public static void main(String[] args) {
        try {
            //create .xls and create a worksheet.
            FileOutputStream fos = new FileOutputStream("D:\\data2excel.xls");
            HSSFWorkbook workbook = new HSSFWorkbook();
            HSSFSheet worksheet = workbook.createSheet("My Worksheet");

            //Create ROW-1
            HSSFRow row1 = worksheet.createRow((short) 0);

            //Create COL-A from ROW-1 and set data
            HSSFCell cellA1 = row1.createCell((short) 0);
            cellA1.setCellValue("Sno");
            HSSFCellStyle cellStyle = workbook.createCellStyle();
            cellStyle.setFillForegroundColor(HSSFColor.GOLD.index);
            cellStyle.setFillPattern(HSSFCellStyle.SOLID_FOREGROUND);
            cellA1.setCellStyle(cellStyle);

            //Create COL-B from row-1 and set data
            HSSFCell cellB1 = row1.createCell((short) 1);
            cellB1.setCellValue("Name");
            cellStyle = workbook.createCellStyle();
            cellStyle.setFillForegroundColor(HSSFColor.LIGHT_CORNFLOWER_BLUE.index);
            cellStyle.setFillPattern(HSSFCellStyle.SOLID_FOREGROUND);
            cellB1.setCellStyle(cellStyle);

            //Create COL-C from row-1 and set data
            HSSFCell cellC1 = row1.createCell((short) 2);
            cellC1.setCellValue(true);

            //Create COL-D from row-1 and set data
            HSSFCell cellD1 = row1.createCell((short) 3);
            cellD1.setCellValue(new Date());
            cellStyle = workbook.createCellStyle();
            cellStyle.setDataFormat(HSSFDataFormat
                    .getBuiltinFormat("m/d/yy h:mm"));
            cellD1.setCellStyle(cellStyle);

            //Save the workbook in .xls file
            workbook.write(fos);
            fos.flush();
            fos.close();
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }

    }

}

我将这些jar文件包含在代码文件夹中； commons-codec-1.9.jar poi-3.11-beta2.jar poi-ooxml-3.11-beta2.jar poi-ooxml-schemas-3.11-beta2.jar stax-api-1.0.1.jar xmlbeans-2.6.0.jar

这些是我的命令； javac“ Export2Excel.java” java“ Export2Excel”

有人可以指出正确的方向来解决这个问题吗？

错误“包org.apache.poi.hssf.usermodel不存在，导入org.apache.poi.hssf.usermodel.HSSFSheet;”
