	private File upload;//临时存储的文件
	private String uploadFileName;//上传的文件名
	private String uploadContentType;//文件类型
	private String savePath;//保存目录通过struts动态设置目录
	
	
	
	
	public String getSavePath() {
		return savePath;
	}
	public void setSavePath(String savePath) {
		this.savePath = savePath;
	}

    public void setUploadContentType(String uploadContentType) {

	}





	@Override
	public String execute()throws Exception{
		
        String realPath=ServletActionContext.getServletContext().getRealPath(this.getSavePath());
		File saveFile=new File(realPath,uploadFileName);
		
		FileUtils.copyFile(upload, saveFile);
		
		System.out.println("realPath："+realPath);//创建指定的目录
		System.out.println("upload.getName():"+upload.getName());//临时文件.tmp
		System.out.println("upload.toString:"+upload.toString());//临时文件.tmp
		System.out.println("uploadFileName:"+uploadFileName);//上传的文件名
		System.out.println("uploadContentType："+uploadContentType);//上传的文件类型
		System.out.println("savePath:"+savePath);//通过struts.xml文件设置的目录：如：/tempUpload
		System.out.println("saveFile.toString:"+saveFile.toString());//保存文件的真实目录包括文件名字
		return SUCCESS;
	}
   
}
