您可以使用 Apache POI 库来操作 Excel 文件,具体来说,可以通过设置单元格样式的方式来实现单元格右对齐。以下是一个示例代码:
```java
import org.apache.poi.ss.usermodel.*;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;
import java.io.FileOutputStream;
import java.io.IOException;
public class ExcelWriter {
public static void main(String[] args) throws IOException {
Workbook workbook = new XSSFWorkbook();
Sheet sheet = workbook.createSheet("Sheet1");
// 创建单元格样式
CellStyle style = workbook.createCellStyle();
style.setAlignment(HorizontalAlignment.RIGHT);
// 创建单元格并设置样式
Row row = sheet.createRow(0);
Cell cell = row.createCell(0);
cell.setCellValue("右对齐");
cell.setCellStyle(style);
// 输出到文件
FileOutputStream outputStream = new FileOutputStream("test.xlsx");
workbook.write(outputStream);
outputStream.close();
}
}
```
