目前一个项目需要使用到用户信息导入功能，使用的是excel表单，有没有有这方面demo的大神，最好是适配谷歌、IE、火狐三大浏览器。谢谢。itxuxiang@sina.com
首先你要找到支持导入，导出的jar包，然后网上大把的资料进行参考，如：
String path = "F:\ZHY_WORK\hospital_20160926.xls";
List list = null;
try {
list = ExcelHelper.exportListFromExcel(new File(path), 0);
String regionName=null;//省
String cityName=null;//城市
String hospitalName=null;//医院
String departmentName=null;//科室
String[] strs=null;
Region r = null;
Hospital h= null;
Department d=null;
int rid=0;//省ID
int hid=0;//医院ID
int did=0;//科室ID
String createTime=SimplementDate.getStrformatH(new Date());
for (String str : list) {
｝
ExcelHelper.java这个类去网上一搜，大把
首先给你推荐一个前端插件：jquery.ocupload-1.1.2.js 帮助你解决上传问题（使用方法网上搜）
当你进去后端controller时：用poi的导出形式
import org.apache.commons.fileupload.FileItem;
import org.apache.poi.ss.usermodel.Row;
import org.apache.poi.ss.usermodel.Sheet;
import org.apache.poi.ss.usermodel.Workbook;
import org.apache.poi.ss.usermodel.WorkbookFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.multipart.commons.CommonsMultipartFile;
import org.springframework.web.servlet.ModelAndView;
需要的jar 百度框搜索（poi导出需要jar包）
然后开始写代码:下面是我的小dome，参考基本导出方式
@CheckLogin(ResultTypeEnum.json)
@RequestMapping("power/importExpertUser")
@ResponseBody
public JsonResult importExpertUser(HttpServletRequest request,
@RequestParam(required = false) CommonsMultipartFile uploadFile)
throws Exception {
JsonResult jsonResult = new JsonResult();
Workbook excel = null;
FileItem fileItem = uploadFile.getFileItem();
InputStream inputStream = fileItem.getInputStream();
try {
// 得到excel对象
excel = WorkbookFactory.create(inputStream);
// 得到excel对象的第一张表的 sheet对象
Sheet sheet = excel.getSheetAt(0);
// 遍历每列的数据，并放到list数组中
List list = new ArrayList();
// 第一次的遍历是表头，不需要插入到数据库中
int i = 0;
for (Row row : sheet) {
if (0 == i) {
i++;
continue;// 跳出本次循环
}
// String id = row.getCell(0).getStringCellValue();
String type = row.getCell(0).getStringCellValue();
String name = row.getCell(1).getStringCellValue();
String loginName = row.getCell(2).getStringCellValue();
String loginPass = row.getCell(3).getStringCellValue();
String phone = row.getCell(4).getStringCellValue();
String remark = row.getCell(5).getStringCellValue();
ExpertUser expertUser = new ExpertUser();
expertUser.setType(type);
expertUser.setName(name);
expertUser.setLoginname(loginName);
expertUser.setPhone(phone);
expertUser.setRemark(remark);
Encrypt des = new Encrypt();// 自定义密钥
expertUser.setPassword(des.encrypt(loginPass));
list.add(expertUser);
powerService.importExpertUser(list);
jsonResult.setResult(Const.RESULT_SUCCESS);
jsonResult.setMessage("保存成功");
return jsonResult;
}
} catch (Exception e) {
e.printStackTrace();
jsonResult.setResult(Const.RESULT_ERROR);
jsonResult.setMessage("保存失败");
return jsonResult;
}
return jsonResult;
}
主要你要找到上传文件的jar，然后前端用二楼的方式去实现。

首先，前台的文件上传插件，可以用jquery.fileupload.js插件进行上传，可以控制上传文件的类型及大小；
其次，就是后台controller层，如果用springMVC接收文件表单的话，直接用注解MultipartFile excelFile类型的参数接收文件表单；
最后，就是解析excel文件内容，可以用poi进行解析，就是简单的API调用了。
建议还是自己去实现，收获会更多的。
