EasyExcel使用模板填充数据

public void fillExcel(HttpServletResponse response) throws IOException {
        ServletOutputStream out = response.getOutputStream();
        response.setContentType("multipart/form-data");
        response.setCharacterEncoding("UTF-8");
        //文件名字
        String fileName = "demo.xlsx";
        response.setHeader("Content-disposition", "attachment;filename=" +fileName);
        //文件模板输入流，将excel模板放到resources目录下
        InputStream inputStream = new ClassPathResource("templates/demo.xlsx").getInputStream();
 
        //标题数据
        FillTitle fillTitle = new FillTitle();
        fillTitle.setTitleDate(new Date());
        //列表数据
        List<FillData> list = new ArrayList<>();
        for (int i = 0; i < 10; i++) {
            FillData fillData = new FillData();
            fillData.setName("张三");
            fillData.setNumber(5.2);
            list.add(fillData);
        }
 
        ExcelWriter writer = EasyExcel.write(out).withTemplate(inputStream).build();
        WriteSheet sheet = EasyExcel.writerSheet(0).build();
        //填充列表开启自动换行,自动换行表示每次写入一条list数据是都会重新生成一行空行,此选项默认是关闭的,需要提前设置为true
        FillConfig fillConfig = FillConfig.builder().forceNewRow(true).build();
        //填充标题
        writer.fill(fillTitle,sheet);
        //填充数据
        writer.fill(list,fillConfig,sheet);
        //填充完成
        writer.finish();
        out.flush();
 
    }
