【EasyExcel】 easyExcel 3.2.1 生成多sheet的xlsx文件

 

pom依赖：

<dependency><groupId>com.alibaba</groupId><artifactId>easyexcel</artifactId><version>3.2.1</version></dependency>

 

核心util写法：

import com.alibaba.excel.EasyExcel;
import com.alibaba.excel.ExcelWriter;
import com.alibaba.excel.write.metadata.WriteSheet;
import lombok.extern.slf4j.Slf4j;import java.io.File;
import java.util.List;/*** xlsx工具类* @date 2025/02/05*/
@Slf4j
public class XlsxUtil {public static String createMultiSheetXlsx(String fileName, List<XlsxSheetVO> multiSheetList){String tempFilePath = "/" + fileName + ".xlsx";ExcelWriter excelWriter = EasyExcel.write(tempFilePath).build();for (XlsxSheetVO xlsxSheetVO : multiSheetList) {WriteSheet writeSheet = EasyExcel.writerSheet(xlsxSheetVO.getSheetName()).head(xlsxSheetVO.getClazz()).build();excelWriter.write(xlsxSheetVO.getContext(), writeSheet);}// 关闭writer，释放内存
        excelWriter.finish();log.info("create createMultiSheetXlsx  file success, file path: {}", tempFilePath);return tempFilePath;}public static void deleteFile(String filePath) {File file = new File(filePath);if (file.exists()) {if (file.isDirectory()) {// 如果是目录，递归删除目录下的所有文件和子目录
                deleteDirectory(file);} else {// 如果是文件，直接删除
                file.delete();}log.info("delete file success, file path: {}", filePath);} else {log.info("file not exist, file path: {}", filePath);}}private static void deleteDirectory(File directory) {File[] files = directory.listFiles();if (files != null) {for (File file : files) {if (file.isDirectory()) {deleteDirectory(file); // 递归删除子目录} else {file.delete(); // 删除文件
                }}}directory.delete(); // 删除空目录
    }
}

 

支持多个sheet的dto:

import lombok.Data;import java.util.List;/*** 支持多个sheet的xlsxSheetVO*/
@Data
public class XlsxSheetVO {private String sheetName;private List<?> context;private Class<?> clazz;}

 

入口大概这样：

List<StampInventoryReportVo> stampInventoryReportVos = new ArrayList<>();
List<StampInventorySimpleReportVo> simpleReportVos = new ArrayList<>();XlsxSheetVO sheet1 = new XlsxSheetVO();
sheet1.setSheetName("ALL");
sheet1.setContext(stampInventoryReportVos);
sheet1.setClazz(StampInventoryReportVo.class);XlsxSheetVO sheet2 = new XlsxSheetVO();
sheet2.setSheetName("差異數據");
sheet2.setContext(simpleReportVos);
sheet2.setClazz(StampInventorySimpleReportVo.class);List<XlsxSheetVO> multiSheetList = Lists.newArrayList();
multiSheetList.add(sheet1);
multiSheetList.add(sheet2);String tempXlsxPath = XlsxUtil.createMultiSheetXlsx(fileName, multiSheetList);

 

 

 

生成文件如下：
