本内容主要包括（文件上传、excel2003数据导入数据库）excel导入数据库功能需要jxl jar包支持
下面是文件上传的前端测试代码
<%@ page language="java" contentType="text/html; charset=UTF-8"

<form action="getAllByExcel" method="post" enctype="multipart/form-data">
<input type="file" name="file" >
<input type="submit" value="上传">
</form>

</html>
下面控制类用于excel文件上传到服务器
@SuppressWarnings("unchecked")
@RequestMapping(value="getAllByExcel" ,method = RequestMethod.POST)
public Object getAllByExcel(HttpServletRequest request,HttpServletResponse response, ModelMap model){
MultipartHttpServletRequest mulltipartRequest=(MultipartHttpServletRequest)request;
MultipartFile files=mulltipartRequest.getFile("file");
//得到上传服务器路径
String path=request.getSession().getServletContext().getRealPath("/WEB-INF/res/upload");
String fileName=files.getOriginalFilename();
try {
InputStream inputStream=files.getInputStream();
byte[] b = new byte[1048576];
int length = inputStream.read(b);
path += "\\" + fileName;
// 文件流写到服务器端
FileOutputStream outputStream = new FileOutputStream(path);
outputStream.write(b, 0, length);
inputStream.close();
outputStream.close();
//解析excel
List<Map<String, Object>> lists=CommonUtil.getAllExcel(path);
此功能需要导入jxl相关jar包，此方法提供excel路径返回List<Map<String, Object>>
//获取excel数据
public static List<Map<String, Object>> getAllExcel(String url){
List<Map<String, Object>> models=new ArrayList<Map<String, Object>>();
try {
File filse=new File(url);
Workbook rwb=Workbook.getWorkbook(filse);
Sheet sheet=rwb.getSheet(0);
int clos=sheet.getColumns(); //获取列数
int rows=sheet.getRows();//获取行数
String[] heads =new String[clos];//保存所有的key值
for (int i = 0; i < rows; i++) {
Map<String, Object> mp =new HashMap<String,Object>();
for(int j=0;j<clos;j++){
if(i == 0 ){
heads[j] = sheet.getCell(j, i).getContents();//获取所有key值
}
else{
mp.put(heads[j], sheet.getCell(j, i).getContents());//获取每行value值
}
}
//如果map不为空则添加到list集合
if (!mp.isEmpty()) {
models.add(mp);
}
}
} catch (Exception e) {
// TODO: handle exception
}
return models;
}
