 后台获取filePostName参数值,即可,

FileOutputStream fos;
				
				fos = new FileOutputStream(this.getRequest().getSession().getServletContext().getRealPath(
						Constants.SPRIT) + fileSaveUrl);
				// 以上传文件建立一个文件上传流
				FileInputStream fis = new FileInputStream(getUpload());
				// 将上传文件的内容写入服务器
				byte[] buffer = new byte[1024];		
				int len = 0;
				while ((len = fis.read(buffer)) > 0)
				{
					fos.write(buffer, 0, len);
				}				  			
				fos.close(); 
				fis.close();
				
				this.getResponse().getWriter().print(fileSaveUrl);	

 fileSaveUrl为返回值,windows下必须返回值不为空,否则不会触发uploadSuccess事件

 

 

HTML调用,如下

$(id).swfuInit({
// 自定义参数值

});
