如何用Java将excel数据导入数据库

Posted 2023-03-19

我前端时间要导数据，，随便找代码弄了一个 能用的，贴给你看看。

public String uploadExcel(HttpServletRequest request) throws Exception
MultipartHttpServletRequest multipartRequest = (MultipartHttpServletRequest) request;
System.out.println("通过传统方式form表单提交方式导入excel文件！");

InputStream in =null;
List<List<Object>> listob = null;
MultipartFile file = multipartRequest.getFile("upfile");
if(file.isEmpty())
throw new Exception("文件不存在！");

in = file.getInputStream();
listob = new ImportExcelUtil().getBankListByExcel(in,file.getOriginalFilename());
in.close();

//该处可调用service相应方法进行数据保存到数据库中，现只对数据输出
for (int i = 0; i < listob.size(); i++)
List<Object> lo = listob.get(i);

System.out.println(lo.get(0));
System.out.println(lo.get(1));

Word word = new Word();
word.setId(UUIDTools.getUUID());
word.setChinese(lo.get(1).toString());
word.setEnglish(lo.get(0).toString());
wordService.saveEnglishWord(word);
/* InfoVo vo = new InfoVo();
vo.setCode(String.valueOf(lo.get(0)));
vo.setName(String.valueOf(lo.get(1)));
vo.setDate(String.valueOf(lo.get(2)));
vo.setMoney(String.valueOf(lo.get(3)));

System.out.println("打印信息-->机构:"+vo.getCode()+" 名称："+vo.getName()+" 时间："+vo.getDate()+" 资产："+vo.getMoney()); */

return "result";


ImportExcelUtil类的getBankListByExcel方法：
public List<List<Object>> getBankListByExcel(InputStream in,String fileName) throws Exception
List<List<Object>> list = null;

//创建excel工作簿
Workbook work = this.getWorkbook(in,fileName);

Sheet sheet = null;
Row row = null;
Cell cell = null;

list = new ArrayList<List<Object>>();

//遍历Excel中所有的sheet
for (int i = 0; i < work.getNumberOfSheets(); i++)
sheet = work.getSheetAt(i);
if(sheet==null)continue;

//遍历当前sheet中的所有行
for (int j = sheet.getFirstRowNum(); j < sheet.getLastRowNum(); j++)
row = sheet.getRow(j);
if(row==null||row.getFirstCellNum()==j)continue;

//遍历所有的列
List<Object> li = new ArrayList<Object>();
for (int y = row.getFirstCellNum(); y < row.getLastCellNum(); y++)
cell = row.getCell(y);
li.add(this.getCellValue(cell));

list.add(li);


// work.close();
return list;
