poi根据模板导入导出数据

导出数据数据库

1.要先获取模板路径（模板放在项目的根目录下了）app

2.获取到表里面的全部单元格ide

XSSFWorkbook wb = new XSSFWorkbook(new FileInputStream(saveFile)); sheets = wb.iterator();//获取到表里面的全部单元格

3.遍历excel中每一个sheet的数据
字体

4.判断表格中标题内容，根据标题内容获取相对应模板sheetspa

5.以后根据此sheet中的单元格位置放相应的数据（这次模板中第一列放的是代号，代号是惟一的，能够根据代号查到相应的数据放入具体单元格中）excel

能够进行for循环进行放入数据，此表中有几行是对下面一些进行分类的小标题，因此要判断当前行中是否有数据，若是有的话在下一行放数据code

6.放入完成以后按照格式导出表格orm

response.setContentType("application/binary;charset=UTF-8");
// 设置响应输出的头类型
response.setHeader("content-Type", "application/vnd.ms-excel");
// 下载文件的默认名称
response.setHeader("Content-Disposition", "attachment;filename=" + downloadFilename + format);
response.setCharacterEncoding("UTF-8");
wb.write(response.getOutputStream());blog

//根据模板导出测评分数
 @Override public void exportInfo(Map<String, Object> map, HttpServletResponse response) throws Exception { SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd"); String format = sdf.format(new Date()); String downloadFilename = ""; //excel模板路径

            while (sheets.hasNext()) { Sheet sheet = sheets.next(); String sheetName = sheet.getSheetName(); List<Map<String, Object>> list = null; if (sheetName.equals("健康")) { map.put("firstSymbol", "H"); map.put("type", 0); List<AssessmentInfoEntity> healList = assessmentInfoService.exportInfo(map); for (int i = 0; i < sheet.getLastRowNum(); i++) { Row row = sheet.getRow(i); if (row != null && !row.equals("")) { if (row.getCell(1) != null && row.getCell(1).getStringCellValue().replace(" ", "") != null && row.getCell(1).getStringCellValue().replace(" ", "") != "") { for (int z = 0; z < healList.size(); z++) { if (row.getCell(0).getStringCellValue().replace(" ", "").equals(healList.get(z).getSymbol())) { //判断数据库代号和excel中代号是否相等

导入表格：ci

1.根据模板导入数据时只能导入日期格式的时间，

但根据模板导出的时候会把时间输出为字符串格式的，因此这时须要对其进行转化（先要判断读到的数据是什么格式的，若是是字符串就进行转化，是日期格式就能够直接放进去）

Map<String, Object> birthday = null;

if (sheet.getRow(3).getCell(i+3).getCellType() == 1) { //1指的是String类型

birthday = DateUtils.getAgeYearMonth2(sdf.parse(String.valueOf(map.get("birthday"))), sdf.parse(sheet.getRow(3).getCell(i + 3).getStringCellValue()));

}else{

birthday = DateUtils.getAgeYearMonth2(sdf.parse(String.valueOf(map.get("birthday"))), sheet.getRow(3).getCell(i + 3).getDateCellValue());

}

listAge.add(birthday);

//导入获取数据
    public List<Map<String, Object>> getHealCellValue(Sheet sheet, Map<String, Object> map) throws ParseException { SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd"); List<AssessmentScoreEntity> list = new ArrayList<>(); List<AssessmentInfoEntity> listInfo = assessmentInfoService.list();//获取全部的题目信息
        for (int i = 4; i < sheet.getPhysicalNumberOfRows(); i++) { List<Map<String, Object>> mapList = new ArrayList<>();//存score数据 list<map<String,Object>>形式
