实现

public void fillInData() {

        // 输入模板路径
        String templatePath = "E:/upload_record.xlsx";
        // 结果输出路径
        String outputPath = "E:/数据上传统计HochladenStatistiks.xlsx";

        //第一个sheet页所用数据
        List<UploadRecordVo> recordList = getUploadRecordExcelData();

        //第二个sheet页左侧所用数据
        List<WeekDataStatisticsVo> yearWeekList = selectYearAndWeek();
        //第二个sheet页右侧所用数据
        List<MonthDataStatisticsVo> yearMonthList = selectYearAndMonth();

        //数据写出
        ExcelWriter writer = EasyExcel.write(new File(outputPath)).withTemplate(new File(templatePath)).build();
        //操作第一个sheet(记得注册自定义的CellWriteHandler)
        WriteSheet sheet1 = EasyExcel.writerSheet(0).registerWriteHandler(new EasyExcelCellWriteHandler()).build();

        //操作第二个sheet
        WriteSheet sheet2 = EasyExcel.writerSheet(1).registerWriteHandler(new EasyExcelCellWriteHandler()).build();


        // 填充第一个sheet页列表数据
        writer.fill(recordList, FillConfig.builder().forceNewRow(Boolean.TRUE).build(), sheet1);

        // 填充第二个sheet页左侧列表数据
        writer.fill(yearWeekList, FillConfig.builder().forceNewRow(Boolean.TRUE).build(), sheet2);

        // 填充第二个sheet页右侧列表数据
        writer.fill(yearMonthList, FillConfig.builder().forceNewRow(Boolean.TRUE).build(), sheet2);

        //设置强制计算公式：不然公式会以字符串的形式显示在excel中
        Workbook workbook = writer.writeContext().writeWorkbookHolder().getWorkbook();
        workbook.setForceFormulaRecalculation(true);

        writer.close();
    }

结果

第一个sheet页

第二个sheet页
