帮小弟看个struts2上传文件报错信息，，在线等！！！
前台jsp：
<form action="<%=basePath%>m/file/uploadFile.action" method="post" enctype="multipart/form-data">
<p><input type="text" name="fileName" id="fileName" value=""></input>File Description</p>
<p><input type="file" name="upload" id="upload" value="file"></input></p>
<p><input type="submit" value="UpLoad"></input></p>
</form>

struts配置文件:

后台action：
package com.start.action;

import java.io.*;

import org.apache.struts2.ServletActionContext;

import com.opensymphony.xwork2.ActionSupport;
import com.start.upload.FileFiler;

public class FileUpLoadAction extends ActionSupport {
//private FileFiler file;
//
//public FileFiler getFile() {
//return file;
//}
//
//public void setFile(FileFiler file) {
//this.file = file;
//}
private String fileName;
private File upload;
private String uploadContentType;
private String uploadFileName;
private String savePath;

public String getFileName() {
return fileName;
}
public void setFileName(String fileName) {
this.fileName = fileName;
}
public File getUpload() {
return upload;
}
public void setUpload(File upload) {
this.upload = upload;
}
public String getUploadContentType() {
return uploadContentType;
}
public void setUploadContentType(String uploadContentType) {
this.uploadContentType = uploadContentType;
}
public String getUploadFileName() {
return uploadFileName;
}
public void setUploadFileName(String uploadFileName) {

this.uploadFileName = uploadFileName;
}
public String getSavePath() {
return ServletActionContext.getRequest().getRealPath(savePath);

}
public void setSavePath(String savePath) {
this.savePath = savePath;
}
public String fileUpload() throws Exception{

//以服务器的文件保存地址和原文件名建立上传文件输出流

FileOutputStream fos=new FileOutputStream(this.getSavePath()+"\\"+this.getUploadFileName());
FileInputStream fis=new FileInputStream(this.getUpload());
byte[] buffer=new byte[1024];
int len=0;
while((len=fis.read(buffer))>0){
fos.write(buffer,0,len);
}

return SUCCESS;
}
}

情况是这样的，debug跟踪到后台FileInputStream fis=new FileInputStream(this.getUpload());再往下就是报错了，文件可以上传，后台也没有报错，但是前台报错了，说临时文件找不到。大大们帮下小弟吧！！

[解决办法]
java.io.FileNotFoundException: \tmp\upload__3e019d96_12ec6707d88__7fff_00000001.tmp (系统找不到指定的文件。)

相对路径不行就换成绝对路径试试
[解决办法]

Java code

FileInputStream fis = new FileInputStream("这里应当是文件的路径和文件名字")
