文件从本地到服务器的功能，其实是为了解决目前浏览器不支持获取本地文件全路径。不得已而想到上传到服务器的固定目录，从而方便项目获取文件，进而使程序支持EXCEL批量导入数据。
java中文件上传到服务器的指定路径的代码：
在前台界面中输入：
<form method="post" enctype="multipart/form-data" action="../manage/excelImport.do">
请选文件:<input type="file" name="excelFile">
<input type="submit" value="导入" onclick="return impExcel()"/>
</form>
action中获取前台传来数据并保存
/**
* excel 导入文件
* @return
* @throws IOException
*/
@RequestMapping("/usermanager/excelImport.do")
public String excelImport(
String filePath,
MultipartFile excelFile,HttpServletRequest request) throws IOException{
log.info("<<<<<<action:{} Method:{} start>>>>>>","usermanager","excelImport" )
if (excelFile != null){
String filename=excelFile.getOriginalFilename()
String a=request.getRealPath("u/cms/www/201509")
SaveFileFromInputStream(excelFile.getInputStream(),request.getRealPath("u/cms/www/201509"),filename)//保存到服务器的路径
}
log.info("<<<<<<action:{} Method:{} end>>>>>>","usermanager","excelImport" )
return ""
}
/**
* 将MultipartFile转化为file并保存到服务器上的某地
*/
public void SaveFileFromInputStream(InputStream stream,String path,String savefile) throws IOException
{
FileOutputStream fs=new FileOutputStream( path + "/"+ savefile)
System.out.println("------------"+path + "/"+ savefile)
byte[] buffer =new byte[1024*1024]
int bytesum = 0
int byteread = 0
while ((byteread=stream.read(buffer))!=-1)
{
bytesum+=byteread
fs.write(buffer,0,byteread)
fs.flush()
}
fs.close()
stream.close()
}
//文件写入流private void ReadFile()
{
Byte[] MesageFile
string path =@"c:\123.XML"
FileStream stream = new FileStream(path, FileMode.Open, FileAccess.Read)
int size = Convert.ToInt32(stream.Length)
MesageFile = new Byte[size]
stream.Read(MesageFile, 0, size)
stream.Close()
string fileName =path.Substring(path.LastIndexOf("\\") + 1, path.Length path.LastIndexOf("\\") - 1)
WriteFile(MesageFile, fileName)
}
//写入文件
private void WriteFile(Byte[] fileByte,string fileName)
{
string path = AppDomain.CurrentDomain.BaseDirectory + "\\UpLoad\\" + DateTime.Now.ToString("yyyy-MM-dd")+"\\"
if (!Directory.Exists(path))
