excel导出

下面为本地生成excel的例子，若需导出，则将文件输出流转为response输出流。

 

package excel;

import java.io.File;
import java.io.FileOutputStream;
import java.io.OutputStream;

import jxl.Workbook;
import jxl.format.UnderlineStyle;
import jxl.write.Colour;
import jxl.write.Label;
import jxl.write.WritableCellFormat;
import jxl.write.WritableFont;
import jxl.write.WritableSheet;
import jxl.write.WritableWorkbook;

public class WriteExcel {
	
	public void writeExcel() throws Exception{
		File file = new File("D:\\Sim\\Project\\Excel\\test2.xls");
		if (!file.exists()) {
			file.createNewFile();
		}
		
		OutputStream os = new FileOutputStream(file);// 取得输出流


        WritableWorkbook wbook = Workbook.createWorkbook(os); // 建立excel文件
        String tmptitle = "测试数据"; // 标题
        WritableSheet wsheet = wbook.createSheet(tmptitle, 0); // sheet名称

        // 设置excel标题
        WritableFont wfont = new WritableFont(WritableFont.ARIAL, 16, WritableFont.BOLD, false,
                                              UnderlineStyle.NO_UNDERLINE, Colour.BLACK);
        WritableCellFormat wcfFC = new WritableCellFormat(wfont);
        wcfFC.setBackground(Colour.AQUA);
        wsheet.addCell(new Label(1, 0, tmptitle, wcfFC));
        wfont = new jxl.write.WritableFont(WritableFont.ARIAL, 14, WritableFont.BOLD, false,
                                           UnderlineStyle.NO_UNDERLINE, Colour.BLACK);
        wcfFC = new WritableCellFormat(wfont);

        // 开始生成主体内容
        wsheet.addCell(new Label(0, 2, "姓名"));
        wsheet.addCell(new Label(1, 2, "性别"));
        wsheet.addCell(new Label(2, 2, "证件类型"));
        wsheet.addCell(new Label(3, 2, "证件号码"));
        wsheet.addCell(new Label(4, 2, "手机号"));
       
        int count = 0;
        for (int i=0;i<10;i++) {
            wsheet.addCell(new Label(0, count + 3, "我是"+i+"号"));
            wsheet.addCell(new Label(4, count + 3, "my phone is:"+i));
            count++;
        }

        // 主体内容生成结束
        wbook.write();   // 写入文件
        wbook.close();
        os.close();   // 关闭流

		
	}
	
}

 

 

pom依赖：

 

		
			org.apache.poi
			poi-ooxml
			3.9
		
		
		
			net.sourceforge.jexcelapi
			jxl
			2.6
		

	

 

结果图： 

 

 

new Label(0, 2, "姓名")  指 新建一格 A3     相当于直角坐标系的X/Y轴定位

x轴 数组对应关系为{0,1,2,3,.......,25} to  {A,B,C,........,Z}

y轴 从也是从0开始
