java 导出到excel
在使用Java导出Excel时,可以使用POI库来实现设置单元格的对齐方式。具体实现步骤如下:
1. 创建工作簿和工作表对象
```java
Workbook workbook = new HSSFWorkbook();
Sheet sheet = workbook.createSheet("sheet1");
```
2. 创建单元格样式对象,并设置对齐方式
```java
CellStyle cellStyle = workbook.createCellStyle();
cellStyle.setAlignment(HorizontalAlignment.RIGHT); // 设置水平对齐方式为右对齐
```
3. 创建单元格对象,并将样式应用到单元格
```java
Row row = sheet.createRow(0);
Cell cell = row.createCell(0);
cell.setCellValue("右对齐文本");
cell.setCellStyle(cellStyle); // 应用单元格样式
```
4. 导出Excel文件
```java
FileOutputStream fos = new FileOutputStream("test.xls");
workbook.write(fos);
fos.close();
```
完整代码示例:
```java
import java.io.FileOutputStream;
import org.apache.poi.hssf.usermodel.HSSFWorkbook;
import org.apache.poi.ss.usermodel.*;
import org.apache.poi.ss.usermodel.HorizontalAlignment;
public class ExcelExporter {
public static void main(String[] args) throws Exception {
Workbook workbook = new HSSFWorkbook();
Sheet sheet = workbook.createSheet("sheet1");
CellStyle cellStyle = workbook.createCellStyle();
cellStyle.setAlignment(HorizontalAlignment.RIGHT); // 设置水平对齐方式为右对齐
Row row = sheet.createRow(0);
Cell cell = row.createCell(0);
cell.setCellValue("右对齐文本");
cell.setCellStyle(cellStyle); // 应用单元格样式
FileOutputStream fos = new FileOutputStream("test.xls");
workbook.write(fos);
fos.close();
}
}
```
