菜鸟的自我救赎，自从有了GPT，还是头一次一个bug写一天。
直接贴导出excel模板的完整案例
EasyExcel填充模板导出excel.xlsx / 导出excel模板
一、bug(不需要请跳过)
1.1 使用apache poi操作excel报错 java.lang.NoSuchMethodError: org.apache.logging.log4j.Logger.atTrace()Lorg/apache/logging/log4j/
1.2EasyPoi读取word时报错java.util.zip.ZipException: Unexpected record signature: 0X9
二、配置文件
xml

使用 @Value("classpath:xx/xx/xxx.xlsx") 获取文件路径

// 设置响应头，告诉浏览器这是一个文件下载请求
String fileName = URLEncoder.encode("导出采购订单详情", "UTF-8") + ".xlsx";
response.setContentType("application/vnd.ms-excel");

}8.2 修改service
由于流使用一次就会关闭，这里选择一次性操作。
你也可以使用缓存的方式分两次写入。
java
@Value("classpath:template/excel/ExportPurchaseOrderDetailsTemplate.xlsx")
private org.springframework.core.io.Resource templateResource;
public void excelExportDetails(String purchaseSeq, HttpServletResponse response) {
try (InputStream templateInputStream = templateResource.getInputStream()) {
// 检查模板文件是否存在
if (!templateResource.exists()) {
throw new RuntimeException("模板文件不存在！路径为：" + templateResource.getDescription());
}
// 设置响应头，告诉浏览器这是一个文件下载请求
String fileName = URLEncoder.encode("导出采购订单详情", "UTF-8") + ".xlsx";
response.setContentType("application/vnd.ms-excel");
response.setCharacterEncoding("utf-8");
response.setHeader("Content-Disposition", "attachment;filename=" + fileName);
AdminPurchaseOrderDetailsExportDTO adminPurchaseOrderDetailsExportDTO = new AdminPurchaseOrderDetailsExportDTO();
adminPurchaseOrderDetailsExportDTO.setOrderStore("1");
adminPurchaseOrderDetailsExportDTO.setStoreCode("21321");
adminPurchaseOrderDetailsExportDTO.setUser("312321");
adminPurchaseOrderDetailsExportDTO.setUserMobile("12321");

excelWriter.fill(orderItemList, writeSheet);
// 结束写入
excelWriter.finish();
}catch (Exception e){
throw new RuntimeException("导出 Excel 文件失败11111111111", e);
}
} catch (Exception e) {
throw new RuntimeException("导出 Excel 文件失败", e);
}
}8.3 成品
这里只做了几个简单的参数例子
