一:导入依赖:

 <dependency><groupId>org.apache.poi</groupId><artifactId>poi</artifactId><version>4.1.2</version></dependency><dependency><groupId>org.apache.poi</groupId><artifactId>poi-ooxml</artifactId><version>4.1.2</version></dependency><dependency><groupId>joda-time</groupId><artifactId>joda-time</artifactId><version>2.10.4</version></dependency><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>4.13.1</version><scope>test</scope></dependency>

二:代码实现:

 

public class ExcelWriteTest {
    String PATH="D:\\Hutool\\src\\main\\resources";
    @Testpublic void test() throws IOException {//创建一个工作蒲Workbook workbook = new HSSFWorkbook();//创建一个工作表   Sheet sheet=workbook.createSheet("小袁粉丝表");//创建一个行Row row=sheet.createRow(0);//创建一个单元格Cell cell=row.createCell(0);
        cell.setCellValue("二十岁以下");
        Cell cell1=row.createCell(1);
        cell1.setCellValue(55);

        Row row1=sheet.createRow(1);//创建一个单元格Cell cell2=row1.createCell(0);
        cell2.setCellValue("时间");
        Cell cell3=row1.createCell(1);
       String time=new DateTime().toString("yyyy-MM-dd HH:mm:ss");
       cell3.setCellValue(time);       //生成表FileOutputStream fileOutputStream = new FileOutputStream(PATH + "小袁粉丝表03.xls");
        workbook.write(fileOutputStream);
        fileOutputStream.close();
        System.out.println("Excel表生成完毕");
    }
}

 

使用POI生成Excel表_Excel表

 

 此时已经生成Excel表

使用POI生成Excel表_Excel表_02
