strtus2中上传时的路劲问题，解决办法

package com.zjlolife.upload;

import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;

import javax.servlet.http.HttpServletRequest;

import org.apache.struts2.ServletActionContext;

import com.opensymphony.xwork2.ActionContext;

public class UploadAction {

	private File upload;
	
	private String uploadContentType;
	
	private String uploadFileName;
	
	private String savePath;

	

	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 execute() throws Exception{
	
		FileOutputStream fos = new FileOutputStream(getSavePath()+"\\"+uploadFileName);
		FileInputStream fis = new FileInputStream(getUpload());
		int count = 0;
		byte [] buff = new byte[1024]; 
		while((count=fis.read(buff))>0) {
			fos.write(buff, 0, count);
		}
		System.out.println(savePath);
		System.out.println(upload);
		return "success";
	}
	
	

}

用绝对路劲：

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