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";
    @Test
    public 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");
    }
}

 

 

 此时已经生成Excel表
