2024-04-11 03:02:36
这篇blog是介绍:
1. java中的poi技术读取Excel数据，然后保存到MySQL数据中。
2. jxl读写excel
你也可以在 ： java的poi技术读取和导入Excel 了解到写入Excel的方法信息
项目结构：
Excel中的测试数据：
数据库结构：
对应的SQL：
1 CREATE TABLE `student_info` ( 2 `id` int(11) NOT NULL AUTO_INCREMENT, 3 `no` varchar(20) DEFAULT NULL, 4 `name` varchar(20) DEFAULT NULL, 5 `age` varchar(10) DEFAULT NULL, 6 `score` float DEFAULT '0', 7 PRIMARY KEY (`id`) 8 ) ENGINE=InnoDB DEFAULT CHARSET=utf8;
插入数据成功：
如果重复数据，则丢掉：

一. 创建Excel 文档
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;
public class XLS {public static String outputFile = "./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();//创建第一行HSSFRow row = sheet.createRow((short)0);//创建第一列HSSFCell cell = row.createCell((short)0);//定义单元格为字符串类型cell.setCellType(HSSFCell.CELL_TYPE_STRING);//在单元格中输入一些内容cell.setCellValue("增加值");// 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();fOut.close();System.out.println("文件已经生成...");} catch (Exception e) {System.out.println("已运行 xlCreate() : " + e);}}
}
二. 读取Excel文档中的数据
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.FileInputStream;public class XLS {/** windows目录用反斜线 */public static String fileToBeRead = "./test.xls";//"D:\\test1.xls";public static void main(String argv[]) {try {// 创建对Excel工作簿文件的引用HSSFWorkbook workbook = new HSSFWorkbook(new FileInputStream(fileToBeRead));// 创建对工作表的引用。此处按名引用（让我们假定那张表有着缺省名"Sheet1"）HSSFSheet sheet = workbook.getSheet("Sheet0");// 也可用getSheetAt(int index)按索引引用，在Excel文档中，第一张工作表的缺省索引是0，其语句为：HSSFSheet sheet = workbook.getSheetAt(0);// 读取左上端单元HSSFRow row = sheet.getRow(0);HSSFCell cell = row.getCell((short) 0);// 输出单元内容，cell.getStringCellValue()就是取所在单元的值System.out.println("左上端单元是： " + cell.getStringCellValue());} catch (Exception e) {System.out.println("已运行xlRead() : " + e);}}
}
设置单元格格式
在这里，我们将只介绍一些和格式设置有关的语句，我们假定workbook就是对一个工作簿的引用。在Java中，第一步要做的就是创建和设置字体和单元格的格式，然后再应用这些格式：
1、创建字体，设置其为红色、粗体：
|
1
2
3
|
HSSFFont font = workbook.createFont();
font.setColor(HSSFFont.COLOR_RED);
font.setBoldweight(HSSFFont.BOLDWEIGHT_BOLD);
|
2、创建格式
|
1
2
|
HSSFCellStyle cellStyle= workbook.createCellStyle();
cellStyle.setFont(font);
|
3、应用格式
|
1
2
3
4
|
HSSFCell cell = row.createCell(( short ) 0 );
cell.setCellStyle(cellStyle);
cell.setCellType(HSSFCell.CELL_TYPE_STRING);
cell.setCellValue( "标题 " );
|
三. 处理WORD文档
|
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16

public class TestPoi {
public TestPoi() {}
public static void main(String args[]) throws Exception{
FileInputStream in = new FileInputStream( "D:\\a.doc" );
WordExtractor extractor = new WordExtractor();
String str = extractor.extractText(in);
//System.out.println("the result length is"+str.length());
System.out.println(str);
