在 EasyExcel 中,可以通过以下步骤插入图片:
1. 导入 EasyExcel 相关的类库:
```java
import com.alibaba.excel.EasyExcel;
import com.alibaba.excel.write.builder.ExcelWriterBuilder;
import com.alibaba.excel.write.builder.ExcelWriterSheetBuilder;
import com.alibaba.excel.write.builder.ExcelWriterTableBuilder;
import com.alibaba.excel.write.metadata.style.WriteCellStyle;
import com.alibaba.excel.write.metadata.WriteSheet;
import com.alibaba.excel.write.metadata.WriteTable;
import com.alibaba.excel.write.metadata.fill.FillConfig;
```
2. 创建 ExcelWriterBuilder 对象,并指定输出文件路径:
```java
String outputPath = "path/to/output.xlsx";
ExcelWriterBuilder writerBuilder = EasyExcel.write(outputPath);
```
3. 创建 ExcelWriterSheetBuilder 对象,并指定 sheet 名称:
```java
String sheetName = "Sheet1";
ExcelWriterSheetBuilder sheetBuilder = writerBuilder.sheet(sheetName);
```
4. 创建 WriteTable 对象,并指定表格的起始行和起始列:
```java
int startRow = 0; // 起始行
int startCol = 0; // 起始列
WriteTable writeTable = EasyExcel.writerTable(startRow, startCol).build();
```
5. 加载图片到 Excel 中,可以使用 `com.alibaba.excel.write.handler.WriteHandler` 接口的实现类 `com.alibaba.excel.write.handler.impl.DefaultImageWriteHandler`:
```java
String imagePath = "path/to/image.png"; // 图片路径
DefaultImageWriteHandler imageWriteHandler = new DefaultImageWriteHandler(imagePath);
writeTable.setWriteHandler(imageWriteHandler);
```
注意:`DefaultImageWriteHandler` 是 EasyExcel 提供的默认实现类,也可以自定义实现 `WriteHandler` 接口,进行更多的图片处理操作。
6. 将 WriteTable 对象添加到 WriteSheet 中,并将 WriteSheet 添加到 ExcelWriterSheetBuilder 中:
```java
WriteSheet writeSheet = EasyExcel.writerSheet(sheetName).build();
writeSheet.setWriteTable(writeTable);
sheetBuilder.withWriteSheet(writeSheet);
```
7. 完成写入并关闭 ExcelWriterBuilder 对象:
```java
writerBuilder.build().finish();
```
通过以上步骤,就可以将图片插入到 EasyExcel 中了。记得替换代码中的文件路径和文件名,以适应你的实际情况。
