要使用EasyExcel.write导出内容居中,可以通过设置样式来实现。具体步骤如下:
1. 导入所需的类和包:
```java
import com.alibaba.excel.EasyExcel;
import com.alibaba.excel.write.style.HorizontalCellStyleStrategy;
import org.apache.poi.ss.usermodel.HorizontalAlignment;
import org.apache.poi.ss.usermodel.VerticalAlignment;
```
2. 创建一个样式策略对象,并设置内容居中的样式:
```java
HorizontalCellStyleStrategy styleStrategy = new HorizontalCellStyleStrategy.Builder()
.setHorizontalAlignment(HorizontalAlignment.CENTER) // 设置水平居中
.setVerticalAlignment(VerticalAlignment.CENTER) // 设置垂直居中
.build();
```
3. 使用样式策略对象来创建ExcelWriter对象:
```java
ExcelWriter excelWriter = EasyExcel.write("文件路径")
.registerWriteHandler(styleStrategy) // 注册样式策略
.build();
```
4. 编写导出逻辑,并使用ExcelWriter对象进行导出:
```java
excelWriter.write(data, sheet) // data为导出的数据,sheet为导出的sheet名称
.sheet().doWrite(data);
```
完整示例代码如下:
```java
import com.alibaba.excel.EasyExcel;
import com.alibaba.excel.ExcelWriter;
import com.alibaba.excel.write.style.HorizontalCellStyleStrategy;
import org.apache.poi.ss.usermodel.HorizontalAlignment;
import org.apache.poi.ss.usermodel.VerticalAlignment;
public class ExcelExportUtil {
public static void main(String[] args) {
// 创建样式策略对象
HorizontalCellStyleStrategy styleStrategy = new HorizontalCellStyleStrategy.Builder()
.setHorizontalAlignment(HorizontalAlignment.CENTER) // 设置水平居中
.setVerticalAlignment(VerticalAlignment.CENTER) // 设置垂直居中
.build();
// 创建ExcelWriter对象
ExcelWriter excelWriter = EasyExcel.write("文件路径")
.registerWriteHandler(styleStrategy) // 注册样式策略
.build();
// 编写导出逻辑,并使用ExcelWriter对象进行导出
excelWriter.write(data, sheet) // data为导出的数据,sheet为导出的sheet名称
.sheet().doWrite(data);
// 关闭ExcelWriter对象
excelWriter.finish();
}
}
```
