在Spring Boot中使用POI库可以方便地实现Excel导出,并且可以添加边框效果。下面是一个简单的示例代码:
1. 首先,确保在pom.xml文件中添加POI依赖:
```xml
<dependencies>
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi</artifactId>
<version>3.17</version>
</dependency>
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi-ooxml</artifactId>
<version>3.17</version>
</dependency>
</dependencies>
```
2. 创建一个Excel导出的方法,使用POI库生成Excel,并为需要添加边框的单元格设置边框样式,示例代码如下:
```java
import org.apache.poi.ss.usermodel.*;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;
import java.io.FileOutputStream;
import java.io.IOException;
public class ExcelExporter {
public void exportExcelWithBorder(String filePath) {
Workbook workbook = new XSSFWorkbook();
Sheet sheet = workbook.createSheet("Sheet1");
// 创建单元格样式并设置边框样式
CellStyle cellStyle = workbook.createCellStyle();
cellStyle.setBorderTop(BorderStyle.THIN);
cellStyle.setBorderBottom(BorderStyle.THIN);
cellStyle.setBorderLeft(BorderStyle.THIN);
cellStyle.setBorderRight(BorderStyle.THIN);
Row row = sheet.createRow(0);
Cell cell1 = row.createCell(0);
cell1.setCellValue("姓名");
cell1.setCellStyle(cellStyle);
Cell cell2 = row.createCell(1);
cell2.setCellValue("年龄");
cell2.setCellStyle(cellStyle);
// 导出Excel文件
try (FileOutputStream fos = new FileOutputStream(filePath)) {
workbook.write(fos);
} catch (IOException e) {
e.printStackTrace();
}
}
}
```
3. 在Spring Boot项目中调用导出Excel的方法,示例代码如下:
```java
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
ExcelExporter exporter = new ExcelExporter();
exporter.exportExcelWithBorder("output.xlsx");
}
}
```
以上就是使用Spring Boot实现Excel导出并添加边框样式的简单示例。注意,在使用POI库时,还可以进一步调整样式,如颜色、字体等,以满足具体需求。
