如何用Java将excel数据导入数据库

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 = 0i <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 = 0i <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

}

前台弄个上传标签 访问这个action就行了。

BufferedReader input

try {

String s = new String()

input = new BufferedReader(new FileReader("f:\\123.txt"))

while ((s = input.readLine()) != null) { // 判断是否读到了最后一行

String info[] = s.split(" ")

System.out.println( info[0] + " " + info[1] + " " + info[2] )

}

input.close()

} catch (FileNotFoundException e) {

// TODO Auto-generated catch block

e.printStackTrace()

} catch (IOException e) {

// TODO Auto-generated catch block

e.printStackTrace()

}

把info[0] + " " + info[1] + " " + info[2] 这三个值放在insert语句里就行了 经过测试
