java关于excel的操作

最近在写anroid的一个项目里面用到了将数据库中的信息导出到excel表格的操作，就来记录一下java如何控制excel表格
首先你的需要一个外部jar包：jxl-2.6.12.jar
百度网盘下载：链接：https://pan.baidu.com/s/1aD8_Aryz9EhYhAgr6mAaVw
提取码：zrc1
然后将jar包导入到ecplise中，先在项目里面创建一个lib文件夹，接着不用解压直接复制到lib下

然后右键点击构建路径选择添加至构建路径：

然后写代码：

package test;

import  java.io.File;
import  jxl.Workbook;
import  jxl.write.Label;
import  jxl.write.WritableSheet;
import  jxl.write.WritableWorkbook;
public   class  CreateExcel  {
    public   static   void  main(String args[])  {
        try   {
            //  打开文件
            WritableWorkbook book  =  Workbook.createWorkbook( new  File( " test.xls " ));
            WritableSheet sheet  =  book.createSheet( " 第一页 " ,  0 );       
            Label label1  =   new Label( 0 ,  0 ,  " id号" );
            sheet.addCell(label1);
            Label label2  =   new Label( 1 ,  0 ,  " 姓名" );
            sheet.addCell(label2);
            Label label3  =   new Label( 2 ,  0 ,  " 学号" );
            sheet.addCell(label3);
            Label label4  =   new Label( 3 ,  0 ,  " 性别" );
            sheet.addCell(label4);
            Label label5  =   new Label( 4 ,  0 ,  " 电话号" );
            sheet.addCell(label5);
            Label label6  =   new Label( 5 ,  0 ,  " 年" );
            sheet.addCell(label6);
            Label label7  =   new Label( 6 ,  0 ,  " 月" );
            sheet.addCell(label7);
            Label label8  =   new Label( 7 ,  0 ,  " 日" );
            sheet.addCell(label8);
            //列 行
            jxl.write.Number number  =   new  jxl.write.Number( 0,  1 , 12.0 );
            jxl.write.Number number1  =   new  jxl.write.Number( 1,  1 , 12.0 );
            jxl.write.Number number2  =   new  jxl.write.Number( 2,  1 , 12.0 );
            jxl.write.Number number3  =   new  jxl.write.Number( 3,  1 , 12.0 );
            jxl.write.Number number4  =   new  jxl.write.Number( 4,  1 , 12.0 );
            jxl.write.Number number5  =   new  jxl.write.Number( 5,  1 , 12.0 );
            jxl.write.Number number6  =   new  jxl.write.Number( 6,  1 , 12.0 );
            jxl.write.Number number7  =   new  jxl.write.Number( 7,  1 , 12.0 );
            sheet.addCell(number);
            sheet.addCell(number1);
            sheet.addCell(number2);
            sheet.addCell(number3);
            sheet.addCell(number4);
            sheet.addCell(number5);
            sheet.addCell(number6);
            sheet.addCell(number7);
            book.write();
            book.close();
       }   catch  (Exception e)  {
           System.out.println(e);
       }
   }
}

执行后就在这个项目下生成一个test.xls文件，打开后如图：


是不是很容易
