EasyExcel填充模板导出excel.xlsx

-南帝-2024-10-18 19:09

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

官网冲刺 EasyExcel

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 复制代码 
    <!--以下代码为 使用easyExcel需要用到的包-->
<dependencies>

<!--排除自带低版本poi,解决依赖冲突问题-->

三、 excel模板

四、 模板存放路径

五、 代码

5.1 Controller

参数不需要可以去掉

java 复制代码 
  @GetMapping("/excel/export/details")
    public void excelExport(@RequestParam(name = "xxxx", required = false) String purchaseSeq, HttpServletResponse response) {
        purchaseOrderService.excelExportDetails(purchaseSeq, response);

5.3 Service

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

java 复制代码 
	@Value("classpath:template/excel/ExportPurchaseOrderDetailsTemplate.xlsx")
    private org.springframework.core.io.Resource templateResource;

方法

            response.setContentType("application/vnd.ms-excel");
            response.setCharacterEncoding("utf-8");

                        .withTemplate(templateInputStream) // 使用模板
                        .sheet() // 填充第一个sheet

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。

            response.setContentType("application/vnd.ms-excel");
            response.setCharacterEncoding("utf-8");
            response.setHeader("Content-Disposition", "attachment;filename=" + fileName);

            AdminPurchaseOrderDetailsExportDTO adminPurchaseOrderDetailsExportDTO = new AdminPurchaseOrderDetailsExportDTO();

                WriteSheet writeSheet = EasyExcel.writerSheet(0).build();

                // 填充单个对象数据
                excelWriter.fill(adminPurchaseOrderDetailsExportDTO, writeSheet);

                // 填充对象列表数据
