struts2上传文件到系统根目录，但是一直报路径错误

下面是我写的代码

import java.io.File;

import java.io.FileInputStream;

import java.io.FileNotFoundException;

import java.io.FileOutputStream;

import java.io.IOException;

import java.io.InputStream;

import java.io.OutputStream;

import java.util.List;

import org.apache.struts2.ServletActionContext;

import com.baosight.bocs.spring.service.ImportExcelService;

import com.opensymphony.xwork2.ActionSupport;

public class ImportExcelAction extends ActionSupport {

//上传文件集合

private List file;

//上传文件名集合

private List fileFileName;

//get和set方法就不写了

public get....

public set....

// 执行上传功能

private void uploadFile(int i) throws FileNotFoundException, IOException {

try {

InputStream in = new FileInputStream(file.get(i));

String dir = ServletActionContext.getRequest().getRealPath("/upload");

File uploadFile = new File(dir, this.getFileFileName().get(i));

OutputStream out = new FileOutputStream(uploadFile);

byte[] buffer = new byte[1024 * 1024];

int length;

while ((length = in.read(buffer)) > 0) {

out.write(buffer, 0, length);

}

in.close();

out.close();

} catch (FileNotFoundException ex) {

ex.printStackTrace();

} catch (IOException ex) {

ex.printStackTrace();

}

}

}

然后执行代码后报出的错误

14:21:51,281 ERROR [STDERR] java.io.FileNotFoundException: D:\JAVA\jboss-4.2.0.CR2\server\default\.\deploy\bocs.war\upload\2.14.xls (系统找不到指定的路径。)

我知道是路径不对 但是为什么getRealPath方法得不到正确的绝对路径啊，我用的是ISS框架(Ibatis;Spring;Struts2)

正确的路径是：

D:\JAVA\jboss-4.2.0.CR2\server\default\deploy\bocs.war\upload\2.14.xls

getRealPath方法给我的路径却是：

D:\JAVA\jboss-4.2.0.CR2\server\default\.\deploy\bocs.war\upload\2.14.xls

其中多出了一个“\.\”的目录 没想通这个目录是怎么多出来的
