hutool導出Excel 和 autopoi一對多導出Excel

一.hutool導出方式

1.jar包
poi-4.1.0.jar
poi-ooxml-4.1.0.jar
poi-ooxml-schemas-3.9.jar
poi-scratchpad-3.9.jar

2.方法

//        ArrayList<Map<String, Object>> rows = CollUtil.newArrayList(row1, row2);

        //通過工具類創建writer
        ExcelWriter writer = ExcelUtil.getWriter();

        //通過構造方法創建writer
        //ExcelWriter writer = new ExcelWriter("d:/writeTest.xls");

        //跳過當前行，既第一行，非必須，在此演示用
//        writer.passCurrentRow();


        //自定義標題別名
//        writer.addHeaderAlias("name", "姓名");
//        writer.addHeaderAlias("age", "年齡");
//        writer.addHeaderAlias("score", "分數");
//        writer.addHeaderAlias("isPass", "是否通過");
//        writer.addHeaderAlias("examDate", "考試時間");
        //合併單元格後的標題行，使用默認標題樣式
//        writer.merge(row1.size() - 1, "一班成績單");
        //一次性寫出內容
        writer.write(sfPatrolLogs);

        //response爲HttpServletResponse對象
        //response.setContentType("application/vnd.ms-excel;charset=utf-8");
        response.setContentType("application/octet-stream");
        //test.xls是彈出下載對話框的文件名，不能爲中文，中文請自行編碼
        response.setHeader("Content-Disposition","attachment;filename=PatrolLog.xls");
        ServletOutputStream out=response.getOutputStream();

        writer.flush(out);
        // 關閉writer，釋放內存
        writer.close();

//        return ResponseEntity.ok(Result.success(true));

二.autopoi導出方式

1.jar包
autopoi-web-1.0.2.jar
