Java导出excel表格
可以使用Apache POI库来设置导出的Excel表格纵向打印。具体步骤如下:
1. 创建Workbook对象:
Workbook workbook = new HSSFWorkbook(); // 创建xls格式的Workbook对象
Workbook workbook = new XSSFWorkbook(); // 创建xlsx格式的Workbook对象
2. 创建Sheet对象:
Sheet sheet = workbook.createSheet("Sheet1"); // 创建名为Sheet1的Sheet对象
3. 设置打印方向:
PrintSetup printSetup = sheet.getPrintSetup();
printSetup.setLandscape(false); // 设置为纵向打印
4. 导出Excel表格:
FileOutputStream fos = new FileOutputStream("path/to/excel.xlsx"); // 创建输出流
workbook.write(fos); // 将Workbook对象写入输出流
fos.close(); // 关闭输出流
完整代码示例:
import org.apache.poi.hssf.usermodel.HSSFWorkbook;
import org.apache.poi.ss.usermodel.PrintSetup;
import org.apache.poi.ss.usermodel.Sheet;
import org.apache.poi.ss.usermodel.Workbook;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;
import java.io.FileOutputStream;
import java.io.IOException;
public class ExcelExport {
public static void main(String[] args) throws IOException {
Workbook workbook = new XSSFWorkbook(); // 创建xlsx格式的Workbook对象
Sheet sheet = workbook.createSheet("Sheet1"); // 创建名为Sheet1的Sheet对象
PrintSetup printSetup = sheet.getPrintSetup();
printSetup.setLandscape(false); // 设置为纵向打印
FileOutputStream fos = new FileOutputStream("path/to/excel.xlsx"); // 创建输出流
workbook.write(fos); // 将Workbook对象写入输出流
fos.close(); // 关闭输出流
}
}
