struts2实现文件上传功能(FileUtils类的copyFile方法实现) 

//action类代码
package com.rocky.uploadaction;

import java.io.File;

import org.apache.commons.io.FileUtils;
import org.apache.struts2.ServletActionContext;

import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.ActionSupport;

public class ImageAction extends ActionSupport {
	public File fileN;
	public String fileNFileName;

	public File getFileN() {
		return fileN;
	}

	public void setFileN(File fileN) {
		this.fileN = fileN;
	}

	public String getFileNFileName() {
		return fileNFileName;
	}

	public void setFileNFileName(String fileNFileName) {
		this.fileNFileName = fileNFileName;
	}

	public String excute() throws Exception {
		if (fileN != null) {
			String save = ServletActionContext.getServletContext().getRealPath(
					"/images");
			File f = new File(save);
			if (!f.exists())
				f.mkdirs();
			FileUtils.copyFile(fileN, new File(f, fileNFileName));
			ActionContext.getContext().put("message", "文件上传成功！");
		}
		return "success";
	}

}
