引入pom：

<dependency><groupId>com.alibaba</groupId><artifactId>easyexcel-core</artifactId><version>3.1.1</version><scope>compile</scope></dependency>

编写自定义拦截器：

java">
import com.alibaba.excel.write.handler.SheetWriteHandler;
import com.alibaba.excel.write.metadata.holder.WriteSheetHolder;
import com.alibaba.excel.write.metadata.holder.WriteWorkbookHolder;/*** 自定义模板导出sheet拦截器*/
public class CustomTemplateSheetStrategy implements SheetWriteHandler {private Integer sheetNo;private String sheetName;public CustomTemplateSheetStrategy(String sheetName) {this.sheetName = sheetName;}public CustomTemplateSheetStrategy(Integer sheetNo, String sheetName) {this.sheetNo = sheetNo;this.sheetName = sheetName;}@Overridepublic void beforeSheetCreate(WriteWorkbookHolder writeWorkbookHolder, WriteSheetHolder writeSheetHolder) {}/*** 功能：动态修改模板中sheet的名称* sheet创建完成后调用* @param writeWorkbookHolder* @param writeSheetHolder*/@Overridepublic void afterSheetCreate(WriteWorkbookHolder writeWorkbookHolder, WriteSheetHolder writeSheetHolder) {if (sheetName == null) {return;}if (sheetNo == null) {sheetNo = 0;}writeWorkbookHolder.getCachedWorkbook().setSheetName(sheetNo, sheetName);}
}

生成excel代码：

java">// ...省略外层接口逻辑
try (//文件模板输入流InputStream inputStream = new ClassPathResource("//使用系统路径+文件名").getInputStream();ExcelWriter excelWriter = EasyExcelFactory.write(getOutputStream(fileName, response)).withTemplate(inputStream).registerWriteHandler(new CustomTemplateSheetStrategy(0//sheet序号，从0开始 , "// 自定义sheet名称")).autoCloseStream(Boolean.TRUE).build()) {WriteSheet sheet0 = EasyExcelFactory.writerSheet(0, "基本信息表").build();
//填充配置：forceNewRow为true列表自动换行FillConfig fillConfig = FillConfig.builder().forceNewRow(true).build();// 填充excelWriter.fill(// 数据, sheet0);
// 填充完成excelWriter.finish();} catch (IOException e) {e.printStackTrace();}
// 省略后续逻辑
